Hi there! :)

<u>Answer:</u>

Donovan babysat for 7 hours on Saturday in order to earn $31.50.


Step-by-step explanation:

In order for you to answer your question, you'll need to use the cross product method:

$9         → 2 hours

$31.50  → X hours

<u>(2 × 31.50)</u> ÷ 9 = X hours

<u>63 ÷ 9</u> = X hours

<u>7 = X hours</u>


There you go! I really hope this helped, if there's anything just let me know! :)

Answer:

To know the answer we'll have to divide 9 by 2 to know how much money Donovan would make in one hour.

9 ÷ 2 = 4.5

So that means Donovan makes $4.05 dollars per hour.

Now we'd divide $31.50 by $4.05 or, 31.50 ÷ 4.5 =

7.

Which means that Donovan babysat for <u><em>7 </em></u> hours.


Hope this helps.

Each month, a shopkeeper spends 5x+11 dollars on rent and electricity. if he spends 2x-3 dollars on rent, how muck dose he spend
timofeeve [1]
Rent and electricity = 5x + 11
rent = 2x - 3

electricity = (5x + 11) - (2x - 3) 
electricity = 5x + 11 - 2x + 3
electricity = 3x + 14

Write the slope-intercept form of an equation that passes through the given points.<br> (4,1),(8,2)
Talja [164]

Answer:

y = 1/4x or y = 0.25x

Step-by-step explanation:

In this question, we are trying to write an equation with the given points.

To solve this question, we would use the slope formula: y2-y1/x2-x1

Find the slope by plugging in variables:

2-1/8-4

1/4 = m

The slope would be 1/4

Find the y intercept:

To find the y-intercept, you would need to use the slope you've found and one point, and plug it into the slope-intercept equation:

1 = 1/4(4) + b

Solve:

1 = 1/4(4) + b

1 = 1 + b

Subtract 1 from both sides

0 = b

This means that the y-intercept is 0.

Our equation will be: y = 1/4x

2³+2²+2÷2²+2+1=2 prove that this relation is true for any natural numbers
UkoKoshka [18]

So, this question is basically asking us "If we had an x instead of a 2, would this be true?" We can try and see what we get:

\frac{x^3+x^2+x}{x^2+x+1}=x

So, if we want to show this we have to change the numerator or denominator in such a way that we can cancel some common factors. Notice that x^3+x^2+x=x(x^2+x+1)

If we replace the factored numerator with the original one, we get:

\frac{x(x^2+x+1)}{x^2+x+1}=x \implies \\ x=x

Since we have an equality, this relation is proved.
