Simple problem:

When simplifying 3(x-6) they subtracted 3 instead of multiplied by 3.
3(x-6) should be 3x-18.
Now when you simplify:
3x-18+4x+12-6x
Which is x -6 =0
Or x =6

The population of Jacksonville in 2018 is estimated to be 19,000 people with an annual rate of increase of 3.4%. Which equation
Umnica [9.8K]

Answer:

P=19,000(1.034)^{t}

Step-by-step explanation:

Let

P-------> the population of Jacksonville

t----> the number of years since 2018

we know that

The equation that models the population of Jacksonville in t years is

P=19,000(1+r)^{t}

we have

r=3.4\%=3.4/100=0.034

substitute

P=19,000(1+0.034)^{t}

P=19,000(1.034)^{t}

Given f(x)=4/5x + 13, find the inverse f-¹(x)<br>Given f(x)= 3/x+10 + 4 find the inverse f-¹(x)​
Elodia [21]
  • f-¹(x) = 69/5y
  • f-¹(x) = 13 + 4y/(y + 10)

<h3>How to determine the inverse </h3>

The steps involved in determining the inverse of a function are;

  • Replace f(x) with y in the equation describing the function
  • Interchange x and y
  • Solve for y
  • Replace y by f-1(x)

If f(x) = 4/5x + 13

y = 4/5y + 13

y = 4 + 65 /5y

f^-1 = 4 + 65 /5y

f^-1(x)= 69/5y

If f(x)= 3/x+10 + 4

y = 3/y + 10 + 4

y = 3 + 4y + 10/(y + 10)

y = 13 + 4y/(y + 10)

f^-1(x) = 13 + 4y/(y + 10)

Thus, the inverse of the functions is 69/5y and 13 + 4y/(y + 10)

A restaurant has 15 1/5 pounds of ground beef to make meat loaves. Each meat loaf requires 2 2/8 pounds of ground beef. How many
frosja888 [35]

Answer:

First make mixed

15 x 5 = 75+1=76

76/5

2x8=16+2=18

18/8

Divide

76/5 / 18/8

Use the reciprocal and multiply

76/5 x 8/18

76x8=608

5x18=90

608/90

Simplify

608/2=304

90/2=45

304/45

6 and 34/45 meat loaves

Hope this helps
