Step-by-step explanation:
y = -5x - 1 should be your function.
Check. Plug in the x to get the desired y
9 = -5(-2) - 1
9 = 10 - 1
9 = 9 (correct)
4 = -5(-1) - 1
4 = 5 - 1
4 = 4 (correct)
-1 = -5(0) - 1
-1 = 0 - 1
-1 = -1 (correct)
etc.

The would both be correct in it's own way depending on how the teacher is teaching.
Answer:
see explanation
Step-by-step explanation:
Given
+ 2c + 11
= - + 2c + 11
= 3c - 1 + 2c + 11
= 5c + 10
(b)
We have the expression
5c + 10 ← factor out 5 from each term
= 5(c + 2)
We have two unknowns from the equation therefore, two equations are needed. These equations are:
<span>
3x + y = 9
y = –4x +10
To solve for y, we first substitute the second equation to the first one.
</span>3x + –4x +10<span>= 9
</span><span>x = 1
We substitute the value of x to either of the equations and solve for y.
</span>y = –4(1) +<span>10
</span><span>y = 6
</span>
The Answer Is 500. 350 Is 70% Of 500.
