Answers
Answer: {(-6, -6), (-2,-2), (7,-6),(-5,0)}
Step-by-step explanation:
To find the ordered pairs that represent a function, we want to find one that doesn't have multiple outputs for one input.
{(-6, -6), (-2,-2), (7,-6),(-5,0)} is the correct answer because all the x are different, and have only one output.

3x - 6 = 2(x + 4). find the value
Answers
Multiply x by two and 4 by 2 to get
3x - 6 = 2x + 8
You want the x to be alone on one side so you add six on both sides to get rid of it to get:
3x = 2x + 14
You still don’t have just one x and it isn’t alone on one side, so you subtract 2x from both sides and get
x = 14

(x - 3)(x + 5) + (x - 3)(2x - 1)

Answer:
144 cm²
Step-by-step explanation:
A prism's surface has 2 triangles & 3 rectangles.
In both the triangles , length of :
Perpendicular = 4 cm
Base = 6 cm
So , Area of both triangles = [tex]2(\frac{1}{2} * Base * Perpendicular) = 2(\frac{1}{2}* 6 * 4) = 24 cm^2[/tex]
In the 3 rectangles ,
Length = 8 cm
Width = 5 cm
So , Area of the rectangles = [tex]3( Length * Width) = 3(8 * 5) = 120 cm^2[/tex]
Hence the total surface area of the prism is = 120 + 24 =144 cm²

Hi there! :)
[tex]\huge\boxed{x = -2}[/tex]
m(x) = 4x + 15
Find the value of "x" that would satisfy m(x) = 7:

Subtract 15 from both sides:
4x = -8
Divide both sides by 4:
x = -2.

Jose has $178.74 in his checking account. He wrote checks for $36.52, $18.92, and $25.93. He also deposited $300.00, $100.00, and $205.16. What is the final balance in Bob's checking account?V
Answers
Answer:
$702.53
Step-by-step explanation:
Start with Jose's initial balance.
[tex]178.74[/tex]
He wrote checks, so we have to subtract the total amount the checks were worth. Let's first add the three amounts.
[tex]36.52+18.92+25.93[/tex]
Solve.
[tex]81.37[/tex]
Subtract the total amount of the checks from Jose's initial balance.
[tex]178.74-81.37[/tex]
Solve.
[tex]97.37[/tex]
The amount above is now what is in Jose's checking account.
But, he also deposited money, meaning he put money in his checking account. Now, let's add the three amounts he deposited.
[tex]300.00+100.00+205.16[/tex]
Solve.
[tex]605.16[/tex]
The amount above is what Jose adds to his checking out.
Add the total value of the deposited money and his new balance.
[tex]605.16+97.37[/tex]
Solve.
[tex]605.16+97.37=702.53[/tex]

JM is parallel to KL by the definition of parallelogram (opposite sides of any parallelogram are parallel)

We're also given angle 2 = angle 3

m=3
b): 97/29 ,64/18,-14/-8, 52/14,-71/-27
No, it does not matters which points you take to calculate the slope because at each point m=3for points (18,64) and (-8,-14)m=-14-64/-8-18
m=-78/-26

6x + 9 = 4x + 25
Answers
Answer:
x = 8
Step-by-step explanation:
Solve for x:
6 x + 9 = 4 x + 25
Subtract 4 x from both sides:
(6 x - 4 x) + 9 = (4 x - 4 x) + 25
6 x - 4 x = 2 x:
2 x + 9 = (4 x - 4 x) + 25
4 x - 4 x = 0:
2 x + 9 = 25
Subtract 9 from both sides:
2 x + (9 - 9) = 25 - 9
9 - 9 = 0:
2 x = 25 - 9
25 - 9 = 16:
2 x = 16
Divide both sides of 2 x = 16 by 2:
(2 x)/2 = 16/2
2/2 = 1:
x = 16/2
The gcd of 16 and 2 is 2, so 16/2 = (2×8)/(2×1) = 2/2×8 = 8:
Answer: x = 8
