Answer:
v=0
Step-by-step explanation:
I think you mean 7(2+5v)=2v+14.
14+35v=2v+14 distribute
33v=0 Subtract 2v and 14
v=0 divide by 33 on both sides
Hope this helps plz mark brainliest if correct :D
Answer:
see the explanation
Step-by-step explanation:
we have
decompose the number 224 in prime factors
substitute
Simplify
Answer:
put x=1/2, you will get, r(1/2)=20*1/2-89
=10-89= -70.

Answer:
1. a, b, c - represent growth
2. b, c, d - represent decay
Step-by-step explanation:
If increasing x results in a larger value, the function represents growth. If it results in a smaller value, the function represents decay.

To answer these questions, you can look at the base and the exponent. When we say "exponent" here, we mean <em>the coefficient of the exponent variable</em>. There are four possibilities:
growth:
- exponent positive, base > 1
- exponent negative, base < 1
decay:
- exponent positive, base < 1
- exponent negative, base > 1

<u>Growth questions</u>:
1.77^x -- growth
1.5^(x/2) -- growth
0.5^(-x) -- growth (= 2^x)
e^(-t) -- decay (e ≈ 2.718)
<u>Decay questions</u>:
1.7^x -- growth
1.7^(-2x) -- decay
(1/3)^x -- decay (= 3^(-x))
2^(-x) -- decay
Answer:
80
Step-by-step explanation:
x*.25=20
x=20/.25
x=80
