Can someone please explain these two math problem. It’s hard for me.

Question 1: 1 inch = 4 feet

Question 2: 9.25 inches

Step-by-step explanation:

Question 1

8 inch / 32 x 12 inch = 1 / 48

scale: 1 inch to 48 inch ( 4 ft)

Question 2

scale factor 0.25 (1/4)

37 inch x 1/4 = 9.25 inch

the answer is 62.8 cubic units

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
