1. 64 - 7c

2. 4x-3

3. p< -28

Step-by-step explanation:

6. -6 -7(c+10)

$-6-7c+70\\-7c+64\\64-7c$

64 - 7c

7. 3x+4(x-6)-3(x-7)

$3x+4x-24-3x+21\\4x-3$

4x-3

8. p+4 < -24

Subtracting 4 from both sides

$p+4-4$

p< -28

Find the zeros of the polynomial function and state the multiplicity of each.

zheka24 [161]

$\bf f(x) = 4(x + 7)^2(x - 7)^3\implies 0 = 4(x + 7)^2(x - 7)^3
\\\\\\
0=(x+7)^2(x-7)^3\implies 
\begin{cases}
0=(x+7)^7\\
\qquad 0=(x+7)(x+7)\\
\qquad -7=x\\
\qquad -7=x\\
----------\\
0=(x-7)^3\\
\qquad 0=(x-7)(x-7)(x-7)\\
\qquad 7=x\\
\qquad 7=x\\
\qquad 7=x
\end{cases}$

the -7 is found there twice, so it has a multiplicity of 2
the +7 is there thrice, so it has multiplicity of 3

Y-x=4 and x is three times the value of y, what is the value of x+y?

slega [8]

Answer:

x+y=-8

Step-by-step explanation:

y-x=4

x=3y

y-3y=4

x=3y

-2y=4

x=3y

y=4/(-2)

x=3y

y=-2

x=3*(-2)

x=-6, y=-2 then

x+y=-6-2=-8

tensa zangetsu [6.8K]

Answer:

B. F(x) = 0.4x² - 1

Step-by-step explanation:

→The function F(x) has shifted downwards, meaning there has to be a 1 being subtracted.

→The function F(x) has grown wider, meaning there has to be a number of absolute value less than 1.

<u>This means answer choice, "B," is correct.</u>

Richland's Real GDP per person is #10b and poorland's Real GDP per person is #5b. However, Richland's Real GDP per person is gro

masya89 [10]

Answer:

after 5 years, rich : poor = 11.0 : 6.7
after 10 years, 12.2 : 9.0
35.3 years

Step-by-step explanation:

It is convenient to let a graphing calculator show the answers to these questions.

The exponential equation modelling the growth will be of the form ...

f(x) = (initial value) × (1 +growth rate)^x

Richland's GDP/person can be modeled by r(x) = 10·1.01^x

Poorland's GCP/person can be modeled by p(x) = 5·1.03^x

The attached graph shows values for x=5, 10 and r(x)=p(x).

It will take about 35.3 years for Poorland to catch up.
