Jessie = Todd + 6
Todd = Ryan -2
if Ryan = r
so Todd = r-2
then Jessie = (r-2) + 6 = r-4 years old
Answer:
3x^ - 4x - 76
Step-by-step explanation:
Answer:
a. 
b. 
Step-by-step explanation:
In numerical expressions we write numbers with the mathematical symbols ( i.e. '+', '-' etc )
a. Given phrase,
Three fifths of seven,
b. One sixth the product of four and eight,
Answer:
0.875
Step-by-step explanation:
7/8 as a decimal is 0.875. Another was of thinking of this is the number '7' is 87.5 percent of the number '8.
We can write the function in terms of y rather than h(x)
so that:
y = 3 (5)^x
A. The rate of change is simply calculated as:
r = (y2 – y1) / (x2 – x1) where r stands for rate
Section A:
rA = [3 (5)^1 – 3 (5)^0] / (1 – 0)
rA = 12
Section B:
rB = [3 (5)^3 – 3 (5)^2] / (3 – 2)
rB = 300
B. We take the ratio of rB / rA:
rB/rA = 300 / 12
rB/rA = 25
So we see that the rate of change of section B is 25
times greater than A
