Answer:

Ayden meet his goal, because I paint 83% of the house that is greater than 80%

Step-by-step explanation:

to know the  part that he painted with respect to the total we have to divide the amount that he paint by the total amount

415ft² / 500ft² = 0.83

if we want it as a percentage we simply multiply it by 100

0.83 * 100 = 83%

now we compare the percentage that I paint with what was his goal

83% > 80%

Ber [7]

Answer:

87

Step-by-step explanation:

A negative times a negative always equals a positive, and 10 times anything is just moving the decimal point to the right once, so 8.7 becomes 87.0

What is the answer plz I really need help

6) slope is 1, y-intercept is 3, equation in slope-intercept form:

y=x+3

7) Slope of the line that goes through the points (3,9) and (-5,3) is Slope=\frac{3}{4}

8) Slope = m= \frac{2}{3}

y-intercept = b= -4

Step-by-step explanation:

6) Create table of coordinate points:

x     y

-2    1

-1     2

0     3

1      4

2     5

Identify the slope:

Using formula:

Slope=\frac{y_2-y_1}{x_2-x_1}

Putting values:

Slope=\frac{2-1}{-1-(-2)}

Slope=\frac{1}{-1+2}

Slope=\frac{1}{1}

Slope=1

So, slope is 1

Identify y-intercept.

y-intercept is found when x=0, so, looking at the table when x = 0, y= 3 so, y-intercept is 3

Equation in the form: y=mx+b

here m is slope and b is y-intercept

Putting values:

y=mx+b\\y=1x+3\\or\,\,y=x+3

So, equation in slope-intercept form:

y=x+3

7) Find the slope of the line that goes through the points (3,9) and (-5,3)

Using formula:

Slope=\frac{y_2-y_1}{x_2-x_1}

Putting values:

Slope=\frac{3-9}{-5-(3)}

Slope=\frac{-6}{-5-3}

Slope=\frac{-6}{-8}

Slope=\frac{3}{4}

So, slope of the line that goes through the points (3,9) and (-5,3) is Slope=\frac{3}{4}

8) What is the slope and y-intercept of the following equation:

y=\frac{2}{3}x-4

The equation is in slope-intercept form

The general equation of slope-intercept form is:

y=mx+b

where m is slope and b is y-intercept

Comparing both equations we get:

Slope = m= \frac{2}{3}

y-intercept = b= -4
