A set of equations is given below:

Equation M: y = 3x + 4

Equation P: y = 3x + 7

Which of the following options is true about the solution to the given set of equations?

A. No Solution

B. One Solution

C. Two Solutions

D. Infinite Solutions

Answers

These would have infinite solutions because this is a slope-intercept equation. Since you are provided with the y-intercept in both, you can put anything in for the slope and it will work.

Step-by-step explanation:

How do you factor out 4v(squared) - 16v + 7?

Answers

it is a square trinomial:
4v^2 - 16v + 7 = 0
lets multiply and divide all by 4, the square term coefficient:
(16v^2 - 16(4)v + 28)(1/4) = 0
(4v - 14)(4v - 2)(1/4) = 0
factor 1/4
(4v - 14)(4v - 2)(1/2)(1/2) = 0
and divide each:
(2v - 7)(2v - 1) = 0

Which is an equation of the line containing (1, -3) and (7, 15)?

Answers

Answer:

You need to find equation of line containing (1,-3) and (7,15)

First find slope (m) = 15+3)/7-1 = 18/6 = 3

So, eq of line is y +3 = 3( x-1)

y+3 = 3x -3

y-3x +6 = 0

9(4 - s) = 10 + 4s
What is the answer?

Answers

36-9s=10+4s
36=10+13s
26=13s
2=s

Hope this helps :)

Before you can do anything, you need to get rid of the parenthesis so you can deal with the numbers inside them.

Distribute the 9:
36-9s=10+4s

Combine like terms (I subtracted the 10 from 36 and added the -9s to 4s)
26=13s

Divide by 13 to get s alone

s=2

Hope this helps

Which value is equivalent to the expression 4 (little 5)?

Answers

the little 5 is an index, sometimes known as a power. to use it we do:
4x4=16
16x4=64
64x4=256
256x4=1024

so the answer is 1024

i hope that makes sense to you, if it doesn't just let me know :)
