Which is the equation of this best line of fit?

Neporo4naja [7]

Answer:

D) y = 5x + 25

Step-by-step explanation:

the line of fit is defined by y = mx + b where:

m = the slope of the line (the rate of change)

b = the y-intercept (where it crosses the y-axis)

We see that for every 1 unit the graph moves horizontally... it moves 5 units vertically, thus we are given m = 5

If you look at the y-axis... we can determine that the graph crosses the y-axis at (0, 25), thus we are given b = 25

Therefore, the answer is y = 5x + 25

HELP!!! please this is my last question for my paper

s2008m [1.1K]

Answer:

$\sqrt{2}$

Step-by-step explanation:

We can use pytho theorem to find X because its a right triangle, so:

a^2 + b^2 = c^2

plug our numbers

1^2 + 1^2 = x^2

simplify

1+1 = x^2

2=x^2

answer = root2

John needs to paint one wall in his school. He knows that 1 can of paint covers an area of 24 square feet. John uses a meter sti

laila [671]

The complete question in the attached figure

step 1
find the area of the wall

[area of the wall]=[area of rectangle]+[area of triangle]
[area of the wall]=[3*2]+[3*1/2]----> 7.5 m²

1 m²-------> 10.7639 ft²

area of the wall------> 7.5*10.7639------> 80.73 ft²

we know that
1 can of paint covers an area of --------> 24 ft²
x---------------------------------------------> 80.73 ft²
x=80.73/24---------> x=3.36 can of paints

the answer is
T<span>he fewest number of cans is 4</span>
