Micah is deciding what rooms of his house he is going to paint. He wants to spend no more than $150 on the paint and supplies.
tatuchka [14]

Answer:

Micah spends $42.21 on paintbrushes.

Paint costs $21.64 per gallon.

Step-by-step explanation:

The paintbrushes are constant/fixed price, the number of gallons of paint are variable, the costs rises linearly with each gallon.

150 - 42.21 = 107.79

The fixed costs for paintbrushes are subtracted from his budget. He then has $107.79 left for paint

107.79 / 21.64 = 4.98105360444

Wich is, it's a pity, slightly less then 5 gallons.

he could buz 4.98 gallons. or, if it has to be a whole number, which I guess it has to be, just 4 gallons and has some money left.

What is the slope of a line that is parallel to the given line.<br> (1 Point)<br> y = 3x+5
Travka [436]
Slope = 3

Given the equation y = 3x + 5, the slope is 3. The slope of a line parallel to the given line would possess the same slope because they never touch. So the slope would simply be 3 as well.

What is the quadratic equation of the curve of best fit shown below
Kisachek [45]
First off, we know that the y-interecept is 2, so there is going to be a plus two in the final equation. Now with the two answers input the number 8 to see which will output 6.

6 = 1/12(8)^(2) + 2
6 = 1/12(64) + 2
6 = 64/12 + 2
6 = 16/3 + 6/3
6 does not equal 22/3

6 = 1/16(8)^(2) + 2
6 = 1/12(64) + 2
6 = 64/16 + 2
6 = 4 + 2
6 = 6
This means that y = 1/16 x^2 + 2 is the correct answer. I hope that helps!
