(5t - 3) · (3t + 7)
t = 6
<u>Step 2: Evaluate</u>
- Substitute in <em>t</em>: (5(6) - 3) · (3(6) + 7)
- (Parenthesis) Multiply: (30 - 3) · (18 + 7)
- (Parenthesis) Subtract: 27 · (18 + 7)
- (Parenthesis) Add: 27 · 25
- Multiply: 675
Answer:
y = 3/8 x
Step-by-step explanation:
the smaller the number the steeper the graph
The answer is 4 units long
the x intercept is where the line crosses the x axis or where y=0
so set y=0 and solve for x
0=-2x-1
solve for x
add 2x to both sides
2x=-1
divide by 2
x=-1/2
the x intercept is at x=-1/2, the point is (-1/2,0)
