Someone please explain how this in general form 2x – 3y – 7 = 0 is 2x - 3y + 10 = 0
Answer:
Step-by-step explanation:
yes....the pair of linear equations has unique solution.....
2x + 3y - 7 = 0 ...... (i)
3x + 2y + 10 = 0 ....... (ii)
on comparing the equation i nd ii with a1x + b1y + c1 = 0

a1 = 2 ; b1 = 3 ; c1 = -7
a2 = 3 ; b2 = 2 ; c2 = 10
here....its clear that......
a1 / a2 is not equal to b1 / b2
Therefore the given pair of linear equation have a unique solution........
5. Find the equation of the line that goes through the points (4,7) and (-2,-5)

where m= gradient or slope
slope = y²-y¹
x²-x¹
= -5-7

equation= y-7=2(x-4)
y-7=2x-8
y= 2x-8+7
y=2x-1
Write an equation in slope-intercept form for the following line:
(-17,-4) and (-7,-13)
Linear equations are often organized in slope-intercept form:
[tex]y=mx+b[/tex]
(x,y) = a point that falls on the linem = the slope of the lineb = the y-intercept of the lineSlope (m)The slope of a line is equal to its [tex]\dfrac{rise}{run}[/tex].
"Rise" refers to the number of units the line travels up."Run" refers to the number of units the line travels to the right.Typically, we would solve for the slope by using the following formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]Y-intercept (b)The y-intercept of a line refers to the y-value that occurs when x=0.
On a graph, it is the y-value where the line crosses the y-axis.
Writing the Equation1) Determine the slope of the line (m)
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Plug in the two given points, (-17,-4) and (-7,-13):
[tex]m=\dfrac{-13-(-4)}{(-7)-(-17)}\\\\m=\dfrac{-13+4}{-7+17}\\\\m=\dfrac{-9}{10}[/tex]
Therefore, the slope of the line is [tex]-\dfrac{9}{10}[/tex]. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-\dfrac{9}{10}x+b[/tex]
2) Determining the y-intercept (b)
[tex]y=-\dfrac{9}{10}x+b[/tex]
Plug in one of the given points and solve for b:
[tex]-4=-\dfrac{9}{10}(-17)+b\\\\-4=\dfrac{153}{10}+b\\\\b=-\dfrac{193}{10}[/tex]
Therefore, the y-intercept of the line is [tex]-\dfrac{193}{10}[/tex]. Plug this back into our equation:
[tex]y=-\dfrac{9}{10}x-\dfrac{193}{10}[/tex]
Answer[tex]y=-\dfrac{9}{10}x-\dfrac{193}{10}[/tex]

Chien always works 20 hours/week at $15/hour and gets paid every 2 weeks.
- What should he expect the gross pay on his next paycheck to be?
- Which one -- gross pay or net pay -- is synonymous with "take home pay"?
- Chien is always dismayed, however, to learn that his net pay is noticeably less. What items on his pay stub could be accounting for the difference?
- When creating his budget, which pay should Chien use and why?
Answer:
$600net paytaxes, insurance, retirement plan contributionsnet payStep-by-step explanation:
The gross pay that shows up on your paycheck is the sum of wages, commissions, and any other earnings your employer may share with you (tips, insurance offsets, bonuses). From this gross pay, government regulations may require the deduction of taxes of various kinds. Your employer may deduct the cost of insurance, and you may voluntarily have amounts deducted for additional taxes, insurance, union dues, or retirement plan contributions. The pay that you take home is the net pay after these deductions.
__
Chien gets paid at the rate of $15 per hour for 20 hours per week and 2 weeks per pay-period. We are not told of any other earnings or contributions to his gross pay. So, it will be ...
($15/h)(20 h/wk)(2 wk/period) = $600/period
Chien's gross pay will be $600 each pay period.
__
As discussed above, "net pay" and "take-home pay" are synonymous.
__
As discussed above, there may be a variety of deductions from his gross pay that will reduce his net pay. Often the largest of these is income tax together with Social Security tax. There may be additional deductions for insurance, union dues, health plan contributions, and retirement plan contributions.
__
Chien's budget should be based on money he actually has available to spend. That would generally be his net pay.
If Chien is considering changing jobs or his family situation, changes to payroll deductions may figure into his budget. Ordinarily, those costs would be considered "fixed" and not subject to a budgeting process.

A decision maker wants to incorporate geographic region into a multiple regression model, where the possible responses are: north, south, east, and west. How many dummy variables will be added to the model
The decision-maker is advised to use three dummy variables. The rule of thumb states that it is better to use lesser dummy variables than the categories being investigated. In this case, the categories are four - North, South, East, and West.
What is a Dummy Variable?This is a statistical term that refers to a factor that is characterized with the value of one or zero in order to explain the presence of absence of an effect that is categorized.
This is used mainly in regression analysis.

help please 50 points Tia and Marcus are having a debate about the graph below. Tia says that this is an x^5 function while Marcus claims that it is an x^4 function. Find the fully factored form of this equation and determine who is correct in the debate. You can use the end behavior chart to help you explain your reasoning.
Answer:
[tex]f(x) = \dfrac14(x + 1)^2(x + 3)(x -2)( x - 3)[/tex]
Tia is correct
Step-by-step explanation:
From inspection of the graph, we can say that the leading coefficient of the function is positive as:
[tex]f(x) \rightarrow - \infty, \textsf { as } \ x \rightarrow - \infty\\f(x) \rightarrow +\infty, \textsf { as } \ x \rightarrow + \infty[/tex]
From inspection of the graph, we can see that the curve intercepts the x-axis at x = -3, x = 2, x = 3
As the curve touches the x-axis at (-1, 0) then this means that the root x = -1 has multiplicity 2
Therefore, [tex]f(x) = a(x + 1)^2(x + 3)(x -2)( x - 3)[/tex] where [tex]a[/tex] is some positive constant.
If we multiply the constants, we can determine the y-intercept:
y-intercept = a x 1² x 3 x -2 x -3 = 18a
Therefore, the y-intercept is at y = 18a
From inspection of the graph, the y-intercept is at y = 4.5
So to determine the value of a: 18a = 4.5 ⇒ a = 1/4
Therefore, the fully factored form of the equation is:
[tex]f(x) = \dfrac14(x + 1)^2(x + 3)(x -2)( x - 3)[/tex]

Answer:
6. mean = 1.4
7. variance = 1.64
standard deviation = √1.64
Step-by-step explanation:
6.
[tex]\textsf{mean }\mu=\[ \sum [x \cdot p(x)][/tex]
⇒ [tex]\mu[/tex] = 0 x 0.4 + 1 x 0.1 + 2 x 0.2 + 3 x 0.3 = 1.4
7. see attached for completed table
[tex]\textsf{variance }\sigma^2=\[ \sum [(x -\mu)^2 \cdot p(x)][/tex]
Therefore, variance is the total of the last column:
[tex]\sigma^2[/tex] = 0.784 + 0.016 + 0.072 + 0.768 = 1.64
standard deviation is the square root of variance:

Bill and Felicia both bake cookies for a party. Bill bakes 3 times as many as Felicia. Felicia bakes 24 fewer cookies than Bill. Bill bakes b cookies and Felicia bakes f cookies. What pair of equations can be used to determine the number of cookies Bill and Felicia bake?
A. b = 3f
f = b - 24
B. b = 3(f + 24)
f = b - 24
C. b = 3f
f = 24 - b
D. f = 3b
b = f - 24
PLEASE HELP ♡
Answer: Below
Step-by-step explanation:
So we start off with b and f. Our first piece of information, Bill baked 3 times as many as Felicia, gives us the equation:
b = 3f
The second piece gives us the equation:
b = f + 24
We have a 3f, but no b = f + 24 in the possible answers. So:
b = f +24
b - 24 = f
Our answer is A.
a. Find the slope of the line that passes through the points (2,-5) and (-2,3).
b. What are the slope and y-intercept of the equation 2x - 5y = -10?
c. Find the x value so that the line through the points (x,-9) and (0,1) has a slope of -4.
d. Write the equation of a line that passes through the point (-1,5) and has a slope of -7. Your answer should be given in the form y = mx + b.
PART A:
Solve for the slope by solving change in y over change in x. We have (3-(-5)/(-2-2) = 8/-4=-2
PART B:
Change in to y=mx+b: -5y = -2x-10. Divide all terms by -5: y = 2/5x + 2. The slope is 2/5 and the y-intercept is 2.
PART C:
Remembering from part a that m=change in y/change in x, we have the equation: -4=1-(-9)/0-x. If we simplify, we have -4=10/0-x. If we multiply both sides from 1/10 we have: -2/5 = -x. So, x = 2/5.
PART D:
We can use point-slope form first:
y-5=-7(x+1). Then we solve the equation! y-5 = -7x-7. After adding 5 to both sides, we have the equation: y=-7x-2.

The perimeter of a square and rectangle are equal . If the square has a side length of 24m and the breadth of the rectangle is 10m , find the length of the rectangle and also find which figure has greater area by how much ?
Answer:
Step-by-step explanation:
Perimeter of the square is 24(4)=96.
Perimeter of the rectangle is 2(10+length)=96
10+length=48
length=38 m
Area of the square is 24^2 = 576.
Area of the rectangle is 10 * 38 = 380
So the square has an area 196 m^2 greater.
