Answer:
- y1 = -x +5
- y2 = 2x +14
- (x, y) = (-3, 8)
Step-by-step explanation:
We notice that x=0 is halfway between x = -1 and x = 1, so the corresponding y-intercepts will be ...
for y1, (6+4)/2 = 5
for y2, (12+16)/2 = 14
Each step in x is +2. The steps in y1 are -2, so the slope is -2/2 = -1.
The steps in y2 are +4, so the slope is 4/2 = 2.
Now, we have the slopes and intercepts, so we can write the system of equations as ...
y1 = -x +5
y2 = 2x +14
__
The y-values are shown as equal in the table for x=-3, so the solution of the system of equations is ...
(x, y) = (-3, 8)
Answer:
<u>The answer is x = -2</u>
Step-by-step explanation:
Let's solve for x the equation -3(x+5)=-9, this way:
-3 (x + 5) = - 9
-3x - 15 = -9 (Solving the parenthesis)
-3x = -9 + 15 (Adding 15 at both sides)
-3x = 6
x = 6/-3 (Dividing by -3 at both sides)
x = -2
<u>The answer is x = -2</u>
