Answer:
0.7 is the growth factor
0.3 is the growth rate
Step-by-step explanation:
Here, we want to get the growth rate and the growth factor
Let us consider the general form of an exponential equation
That will be;
y = a(1 + r)^n
The growth rate is r
while the growth factor is the term (1 + r)
From the given exponential function;
-0.3 is the rate of increase
Growth rate is 1-0.3 = 0.7
Answer:
x = ±3
Step-by-step explanation:
Step 1: Write equation
7x² = 63
Step 2: Solve for <em>x</em>
- Divide both sides by 7: x² = 9
- Square root both sides: x = ±3
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
7(3)² = 63
7(9) = 63
63 = 63
7(-3)² = 63
7(9) = 63
63 = 63
Simplify the following:
-3 w - 5 (6 z - 2 W) - 5 z
-5 (6 z - 2 W) = 10 W - 30 z:
-3 w + 10 W - 30 z - 5 z
-30 z - 5 z = -35 z:
Answer: -3 w + 10 W + -35 z
