Ju chan solved the previous question by finding the expression 4(-15).

which addition problem would give the same result? choose all that apply.
15 + 15 + 15 + 15
4 + 4 + 4 + 4
(–1)(15 + 15 + 15 + 15)
(–15) + (–15) + (–15) + (–15)

(-1)(15+15+15+15)

(-15)+(-15)+(-15)+(-15)

Step-by-step explanation:

1. The multiplication shown in the problem above is:

4(-15)

The product is -60

4(-15)=-60

2. The multiplication above could indicate that:

- The number -15 is added 4 times.

- The number 15 is added 4 times and then is multiplied by -1.

- The number -4 is added 15 times.

- The number 4 is added 15 times and then is multiplied by -1.

 Keeping these on mind, you can conclude that the correct options are the third option and the last option:

(-1)(15+15+15+15)=(-1)(60)=-60

(-15)+(-15)+(-15)+(-15)=-15-15-15-15=-60

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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
