The pair of equations:
y = x + 4
y = -2x - 2
To solve the system of equation by substitution, you would substitute one variable for it's equivalent expression. Combining the pair of equations into one equation in only one variable. The easiest way to do this is by substituting out the variable y because it is already alone on one side of the equal sign. Substitute the y in the second equation for: x+4
x+4 = -2x - 2
solve for x
x + 2x = -2 -4
3x = -6
x = -2
now use the value for x to find y by putting into either equation.
y = x + 4
y = (-2) + 4
y = 2
solution is: (-2, 2)

(2x -3)(2x -1)
Step-by-step explanation:
We have filled in the X-diagram so the side values have a product equal to the top value, and a sum equal to the bottom values (the middle term).
We're not sure how you've been taught to split the leading coefficient to arrive at the factors shown on the right.

The answer is D
Step-by-step explanation:
You multiply the number of hours by 8 to calculate gross pay. Then you form coordinates. In this problem for example (0,0); (3,24); and so on.
Hope this helps!
Answer: 15
Step-by-step explanation: 5 roses are 25 dollars so what your going to do is multiply 5 by 3 to get 15 do the same with 25, 25 x 3 is 75 so you will get 15 roses for 75 dollars
