Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 8x + 5
g(x) = 7x - 2
<u>Step 2: Find f(g(4))</u>
- Substitute in <em>x</em> [Function g(x)]: g(4) = 7(4) - 2
- Multiply: g(4) = 28 - 2
- Subtract: g(4) = 26
- Substitute in function value [Function f(x)]: f(g(4)) = 8(26) + 5
- Multiply: f(g(4)) = 208 + 5
- Add: f(g(4)) = 213
Answer:
26, 33
Step-by-step explanation:
rule is to add 7 everytime
next 2 numbers are 26, 33
Answer:
-2
Step-by-step explanation:
1) Look at the y-intercept. The line crosses the y-axis at (0,7)
Follow it down, it goes down two and over one to directly intersect the grid.
Rise over run = 2/1
2/1 = 2
However, the line is negative, as it's sloping down from the left to the right, making the slope -2
