Answer:
The answer to the question is A
Plz help me!!!!!!!! Which expressions are equivalent?
A.
B.
C.
D.
Answer:
Option A
Step-by-step explanation:
The answer is Option A because [tex]- \frac{2}{3} j + \frac{1}{5}k[/tex] can be writen as [tex]\frac{1}{5}k - \frac{2}{3}j[/tex].
Write an equation for the translation of [tex]y=\frac{4}{x}[/tex] that has the asymptotes x = 7 and y = 6.
Show all your steps, then graph it. (Be sure to link your graph with your steps.)
a.) [tex]y=\frac{4}{x+7}+6[/tex]
b.) [tex]y=\frac{4}{x-6}+7[/tex]
c.) [tex]y=\frac{4}{x+6}+7[/tex]
d.) [tex]y=\frac{4}{x-7}+6[/tex]
______________________________
1.) Substitute x, y, and general form using the formulas: Formula for x: [tex]x=d=7[/tex]Formula for y: [tex]y=k=6[/tex]Formula for general form y: [tex]y=\frac{a}{x-d}+k=y=\frac{4}{x-7}+6[/tex]
Note:
- When doing problems like this, it's best to list out each formula and do the drag down method, and replace methods rather than doing it the entire mathematical way, as doing it that way takes a long time and it's more confusing than it should be.
Equation at the end of Step 1:
[tex]y=\frac{4}{x-7}+6[/tex]2.) Simplify the d and k forms:[tex]y=\frac{4}{x-7}+6=y=\frac{4}{x-7}+6[/tex]
Note:
- The x(d) stays the same since the 7 was positive and we plugged it in making it negative, so it doesn't need to be changed. (Another way to know if you need to change it is if the original [tex](d)[/tex] or [tex](k)[/tex] when plugged in, you had to put them in parenthesis then most likely it needs to be changed.
- The y(k) stays the same since the 6 was positive and we plugged it, keeping it positive so it doesn't need to be changed. (Another way to know if you need to change it is if the original [tex](d)[/tex] or [tex](k)[/tex] when plugged in, you had to put them in parenthesis then most likely it needs to be changed.
So the answer is d, [tex]\bold{y=\frac{4}{x-7}+6}[/tex].

what does it mean for a ordered pair to be a solution to a linear equation
Answer:
What's a Solution to a System of Linear Equations? Note: If you have a system of equations that contains two equations with the same two unknown variables, then the solution to that system is the ordered pair that makes both equations true at the same time.

Complete the equation of the line through (1,4)(1,4)left parenthesis, 1, comma, 4, right parenthesis and (2,2)(2,2)left parenthesis, 2, comma, 2, right parenthesis.
Answer:
[tex]y = -2x + 6[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (1,4)[/tex]
[tex](x_2,y_2) = (2,2)[/tex]
Required
Determine the line equation
First, we calculate the slope (m) using
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{2-4}{2-1}\\[/tex]
[tex]m = \frac{-2}{1}[/tex]
[tex]m = -2[/tex]
The equation is then calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 4 = -2(x - 1)[/tex]
Open bracket
[tex]y - 4 = -2x + 2[/tex]
[tex]y = -2x + 2 + 4[/tex]
[tex]y = -2x + 6[/tex]
Answer:
The answer is y = -2x + 6
Step-by-step explanation:
Complete Question:
Complete the equation of the line through (1,4) and (2,2)
Answer: y = -2x + 6

Heba ate \dfrac{1}{12} 12 1 start fraction, 1, divided by, 12, end fraction of a box of cereal. Now the box is \dfrac{3}{4} 4 3 start fraction, 3, divided by, 4, end fraction full. What fraction of a full box was there before Heba ate
9514 1404 393
Answer:
5/6
Step-by-step explanation:
If q is the quantity of cereal in the box before Heba ate some, the problem tells us ...
q - 1/12 = 3/4
q = 3/4 + 1/12 = 9/12 + 1/12 = 10/12
q = 5/6
There was 5/6 of a box before Heba ate.

Step-by-step explanation:
eddie drinks 12 ounces of water before running and then another 8 ounces each time he runs a mile. Find the number of miles he runs each day if he drinks less than 60 ounces of water when he runs.
Answer:
x>6
Step-by-step explanation:
Your equation would be set up like so:
Y= 8X+12
Then plug in your Y value
60 > 8x+12
Subtract 12
48 > 8x
Divide by 8
x > 6
He runs less than 6 miles a day if he drinks less than 60oz of water. If he drank 60oz TOTAL, he would have run 6 miles TOTAL. (hence why there's no equal sign).
10. Write the equation of the line that is parallel tox-3y = 9 and passes through the point (3,-1).
Answer:
Equation of the line that is parallel tox-3y = 9 and passes through the point (3,-1) is
[tex]y+1= - \frac{1}{3} (x-2)[/tex]
Step-by-step explanation:
Slope of line x-3y = 9 is -1/3
Since Parallel lines have same slope. Therefore slope of line passing through the point (3,-1) is also -1/3.
Equation of line in point slope form is given as
[tex]y-y_1=m(x-x_1)[/tex] ---------- (1)
Here
[tex]m=-\frac{1}{3} \ \ and \ \ (x_1, y_1)= (3, -1)[/tex]
substituting values in equation (1)
[tex]y+1= - \frac{1}{3} (x-2)[/tex]

What is the solution to the equation 2x+4 - 12 = 20?
O X=0
O X=1
O X= 2
O X=9
Answer:
x = 14
Step-by-step explanation:
2x+4 - 12 = 20
2x - 8 = 20
2x = 28
x = 14
The solution is, x = 14, is the solution to the equation 2x+4 - 12 = 20.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have,
given that,
the equation is , 2x+4 - 12 = 20
now, we have to solve it for x
so, for solving the equation,
we isolate the numbers & the variables, then, calculating,
we get,
2x+4 - 12 = 20
2x - 8 = 20
2x = 28
x = 14
Hence, The solution is, x = 14, is the solution to the equation 2x+4 - 12 = 20.
