What is a possible first step and the solution set for - 4x + 10 > 5x + 55? (2 points)
add 10 to each side: xs-45
add 10 to each side: x 25
subtract 10 from each side: x 45
subtract 10 to each side: xs -5

c, after you move the 5x to the left side to make the equation (-4x-5x+10>55), you subtract the +10 to erase it, and also subtract the 55 to be 45.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

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
