X^2 - 7x = 0
Factoring:-
x(x - 7) = 0
x = 0'  x  - 7 = 0 so x = 7

Solution is 0, 7.

First just break it down,
set the value of x to 0 for the equation.
So already x=0.  
x(7+x)=0
-7+x=0
-7+7=0 
Your answer is
x=0
x=7

Which sentence correctly compares the two points shown on the number line? -1 > 0.25 , -1 < -0.25, -0.25 < -1
BartSMP [9]

Answer:

-1<-0.25

With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong

Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.

Question 8(Multiple Choice Worth 1 points) (08.02 MC) Which graph best represents the solution to the following pair of equation
elena-s [515]
<span>y = −2x + 13
y = 2x − 3

</span>−2x + 13  = 2x − 3
subtract 2x on both sides
−2x + 13  −2x = 2x − 3 - 2x
simplify
-4x + 13 = -3
subtract 13 on both sides
-4x + 13 -13  = -3 - 13
simplify
-4x = -16
divide both sides by (-4)
   x = 4

substitute x = 4 into y = 2x − 3 to find y

y = 2x − 3
y = 2(4)− 3
y = 8 - 3
y = 3

answer
solution x = 4 and y = 3

hope it helps
