Art [367]3 years ago
5 0

Answer: 4

Step-by-step explanation:

Set them equal to each other since they're both equal to y

3x-5=.5x +5

add 5 to both sides

3x=.5x+10

subtract .5x from both sides

2.5x=10

divide both sides by 2.5

x= 4

Given the function g(x) = –11 + 12x + x over 3, evaluate g(4).
Paraphin [41]

g(−3)=2

g(0) = 3g(0)=3

Step-by-step explanation:

Given

The attached graph

Required

Determine

g(-3)g(−3)

g(x) = 3g(x)=3

Since a graph has been provided, the question will be solved graphically;

Solving g(-3)

This implies that;

x = -3

And the interpretation is to solve for the y value when x = -3

From the attached graph;

When x = -3; y = 2

Hence;

g(-3) = 2g(−3)=2

Solving g(x) = 3

This implies that;

y = 3

And the interpretation is to solve for the x value when y = 3

From the attached graph;

When y = 3; x = 0

in sub-Saharan African an estimated 28.5 million people are infected with AIDS. Unfortunately that number is rising. and it is e
Viktor [21]

Answer:

About 28,671,342 people

Step-by-step explanation:

This is compound growth problem. This goes by the formula:

F=P(1+r)^t

Where

F is the future amount (in 3 years)

P is the present amount (28.5 million)

r is the rate of growth (0.4% = 0.4/100 = 0.004)

t is the time in years (3 years)

We first, need to find the rate of growth annually. It is given 0.4% every 2 years, so in 1 year that would be:

0.4%/2 = 0.2% = 0.002

Now, we put the information into formula and solve:

F=P(1+r)^t\\F=28500000(1+0.002)^3\\F=28500000(1.002)^3\\F=28,671,342

So, around 28,671,342 people will be infected in 3 years.
