Correct answer will get brainliest
Answer:
4.) Choice B
&
5.) Choice A
Step-by-step explanation:
Question 4:
First you have to solve for y to get slope intercept form.
[tex]2x-5y=6\\5y=-2x+6\\y=-\frac{2}{5}x+\frac{6}{5}[/tex]
The slope is a fraction but you need it to convert it to a decimal so that'll be Choice B.
Question 5:
For this one I we will use this formula [tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
I will choose the easy pairs to plug it in [tex](-12,-2) (20,6)[/tex]
[tex]\frac{6--2}{20--12}\\\\\\\frac{8}{32}=\frac{1}{4}[/tex]
The slope is a fraction again but you can convert it and that'll be Choice A.
P(A) = 2/5 P(B) = 1/4 P(A and B) = ?

D. The slope is 10.
The y-intercept is (0,-5).
Answer:d
Step-by-step explanation:
i just took the test
The slope of the function is 10. The y-intercept is (0,5).
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
The slope of the line is calculated as follows:
m = Δy/Δx
Given that the function y= 10x - 5.
To find the slope and y-intercept of the function y= 10x - 5.
Therefore, the slope of the line is;
m = 10
The y-intercept of the function is (0,5)
Hence,C. The slope is 10.
The y-intercept is (0,5).

Jillian invested $2000 in an account with a 1.25% annual
interest rate. She made no deposits or withdrawals on the
account for 3 years. What was the balance in the account
after the 3 years?
Answer:
the balance is 2075 dollars
Step-by-step explanation:
The answer is 2075 because 1.25% of 2000 is 25 and 25 multiplied by 3 is 75 and 75 plus 2000 is 2075.

On Monday, Elliot rode 6 miles on a bike. On Tuesday, he rode 6 miles. On Wednesday, he rode 3 times farther than he did Monday and Tuesday combined. How many miles has Elliot ridden so far this week?
Answer:
48 miles
Step-by-step explanation:
On Monday, Elliot rode 6 miles on a bike. On Tuesday, he rode 6 miles. On Wednesday, he rode 3 times farther than he did Monday and Tuesday combined.
How many miles has Elliot ridden so far this week?
This is calculated as:
Number of miles he rode on Monday + Number of miles he rode on Tuesday + Number of miles he rode on Wednesday
= 6 miles + 6 miles + 3(6 + 6)miles
= 12 miles + 3(12 miles)
= 12 miles + 36 miles
= 48 miles
Therefore, Elliot has ridden 48 miles so far

Teresa has a $100 gift card to her favorite restaurant. Each day, she uses her gift card to buy the same lunch for $8.50. Colin has a $75 gift card to the same restaurant. His lunches cost $6 each. For what numbers of lunches will Teresa's gift card balance be greater than Colin's gift card balance?
Answer:
12 lunches.
Step-by-step explanation:
Theresa:
$8.50 * 11 = $93.50 so she can buy 11 lunches with her gift card.
Colin:
$6 * 12 = $72 so he can buy 12 lunches with his gift card.
So Colin can buy one more lunch than Theresa. Therefore, if Theresa buys 12 lunches, she will go over her gift card.
The point A (3, 4) is reflected over the line x = 2, and then is reflected over the line x = -4. What are the coordinates of A'?
(9, 4)
(-9, 4)
(1, 4)
(1, 2)
9514 1404 393
Answer:
(-9, 4)
Step-by-step explanation:
Reflection over the line x=a performs the transformation ...
(x, y) ⇒ (2a -x, y)
So, reflection over the two lines will give the transformation ...
(x, y) ⇒ (2·2 -x, y) = (4 -x, y) . . . . . reflection over x=2
then ...
(4 -x, y) ⇒ (2(-4)-(4-x), y) = (x -12, y) . . . followed by reflection over x=-4
__
Reflecting (3, 4) over the two lines gives an image point of ...
(x, y) ⇒ (x -12, y)
(3, 4) ⇒ (3 -12, 4) = (-9, 4)
The coordinates of A' are (-9, 4).

Comment on double reflection
Reflection over the two lines results in a translation that is double the distance between the two lines. The translation is in the direction that the second line is from the first. Here, the lines are 2 -(-4) = 6 units apart, with the second line being to the left of the first. The translation is 12 units to the left.

Write the equation of the line that passes through the points (1,5) and (9,1). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
These are tough, you need a strategy and the formula to go with it, use the point slope formula { y-y1=m(x-x1) } where m = slope and (x1,y1 ) are the points from one of the given points.
find m .. then plug in your point to your formula ... as follows
Step-by-step explanation:
given: (x1,y1)=(1,5) and (x2,y2)=(9,1)
m = y2-y2 / x2- x1
m = 1-5 / 9-1
m = -4 / 8
m = -1/2
use the give point (1,5) and plug in with the slope you just solved for
y-y1 = m (x-x1)
y-5 = -1/2 (x -1)
y-5 = -1/2x + 1/2
y = -1/2x +5 1/2
above is the slope intercept form y = mx +b :) see?
as a side note.. notice that either point (1,5) or (9,1) gets the same slope intercept equation? when it's plugged in, so just use which ever one seems easier to you.
Answer:
This is the point-slope form.
[tex]y - 5 = - \frac{1}{2} (x - 1)[/tex]
Step-by-step explanation:
Let's find the slope first. Remember that:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let's find the slope now.
[tex]m = \frac{1 - 5}{9 - 1} = \frac{ - 4}{ \: \: \: 8} = - \frac{1}{2} [/tex]
-----------------------------------------------------------
Done. Remember that point-slope form is:
[tex]y - y_1 = m(x - x_1)[/tex]
All we have to do now is plug in.
[tex]y - 5 = - \frac{1}{2} (x - 1)[/tex]
And we are now done!

HELP PLZZ, this another one, i got a couple more questions
Answer:
x = 29
y = 10
Step-by-step explanation:
x - 3y = -1
Add 3y to both sides;
x = 3y - 1
2x - 5y = 8
Substitute x
2x - 5y = 8
2(3y - 1) - 5y = 8
Distribute;
6y - 2 - 5y = 8
Collect like terms;
y - 2 = 8
Add 2 to both sides;
y = 10
Substitute y
x - 3y = -1
x - 3(10) = -1
x - 30 = -1
Add 30 to both sides;
x = 29

Answer:
5. 27 + 21 = 48
6. 21 - 3 = 18
7. 12 + 9 = 21
Step-by-step explanation:
I could only see these three but I hope this helps :)
Answer:
4) x = 11
5) x = -6
6) x = 18
7) x = 21
Step-by-step explanation:
(the equations and the answers are bolded)
4)x + 9 = 21
subtract 9 from both sides of the equation
x + 9 - 9 = 21 - 9
x = 21 - 9
x = 11
5)
21 - x = 27
add x to both sides
21 - x + x = 27 + x
21 = 27 + x
subtract 27 from both sides
21 - 27 = 27 - 27 + x
-6 = x
6)
21 = x + 3
subtract 3 from both sides
21 - 3 = x + 3 - 3
21 - 3 = x
21 - 3 = 18
18 = x
7)
x - 9 = 12
add 9 to both sides
x - 9 + 9 = 12 + 9
x = 12 + 9
x = 21
