Answer:

  1. Seconds in second row: 48
  2. Glasses in third row: 11

Step-by-step explanation:

Answer for seconds in second row:

  1. Set up a proportion: \frac{5}{20} = \frac{12}{x}  
  2. Cross multiply, then divide: 20 × 12 = 240, 240 ÷ 5 = 48

Answer for glasses in third row:

  1. Set up a proportion: \frac{5}{20} = \frac{x}{44}  
  2. Cross multiply, then divide: 44 × 5 = 220, 220 ÷ 20 = 11

I hope this helps!

Complete the steps to solve the equation. 9 – 4x = 2x 1. Addition property of equality: 9 = 6x 2. Division property of equality:
exis [7]

x = 3/2

Step-by-step explanation:

Given equation is:

9 - 4x = 2x

As we have to solve for x, x will be isolated on one side of the equation

So,

<u>1. Addition property of equality </u>

4x will be added on both sides

9-4x+4x=2x+4x\\9 = 6x

<u>2. Division property of Equality</u>

Dividing both sides by 6

\frac{6x}{6}=\frac{9}{6}\\x = \frac{3}{2}

Hence,

x = 3/2

Please help! what is y+7=-1/7(x+4) in slope intercept form?
Stells [14]
We know that
the equation of a line in <span>slope intercept form is--------------> y=mx+b
where
m-----------> is the slope
b-----------> is the y-intercept  point when x=0

</span><span>y+7=-1/7(x+4)---------> y+7=(-1/7)x-4/7
</span>y+7=(-1/7)x-4/7------> y=(-1/7)x-4/7-7------> y=(-1/7)x-(53/7)

the answer is
y=(-1/7)x-(53/7)-------------> this is the equation of a line in slope intercept form
m=(-1/7)=-0.14
b=(-53/7)=-7.57
y=-0.14x-7.57

I HAVE 5 MIN TO TURN THIS IN!!!! PLEASE HELP ME!!!<br> IT'S IN THE IMAGE BELOW
Mariulka [41]

Answer:

<h3>a.  x = 8 years</h3><h3>b.  52,000</h3><h3 />

Step-by-step explanation:

company A = 28,000 + 3,000 (x)

company B = 36,000 + 2,000 (x)

where x = no. of years.

  • <u>company A = company B</u>

28,000 + 3,000 (x) = 36,000 + 2000 (x)

3,000 (x) - 2,000 (x) = 36,000 - 28,000

1,000 (x) = 8,000

x = <u>8,000</u>

     1,000

<h3>x = 8 years</h3>

  • plugin value of x = 8 into company A and B

company A = 28,000 + 3,000 (8)

<h3>company A = 52,000</h3>

company B = 36,000 + 2,000 (8)

<h3>company B = 52,000</h3>

Given g(x) where f(x)= 3x-1 and g(x)= f(x+1). graph
tatiyna

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

f(x)=3x-1

we know that

To find out the function f(x+1) exchange the variable x for (x+1) in the function f(x)

so

f(x+1)=3(x+1)-1

f(x+1)=3x+3-1

f(x+1)=3x+2

therefore

g(x)=3x+2

using a graphing tool

see the attached figure
