13. A triangle has vertices with coordinates (-4, 3),
(6, 9), (2, -3). The triangle is translated 7 units
right and 3 units down, what is the rule for this
transformation?

14. Allison’s grandmother deposited $1000 in a
saving account on her birthday. The account
pays 3.5% simple interest. How much interest
will the account earn after 5 years? (I=Prt)

15. Jones deposited $7000 in a certificate of deposit
that pays 2.5% interest compounded annually.
What will be the value of his certificate of
deposit after 5 years? ( A=P(1+r)t)

i believe the answer is d.

hope it you! : d

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

i think the answer is d.

step-by-step explanation:

there are many, many solutions to this problem.

here are 5 examples:

7555531, 7+5+5+5+5+3+1 = 31

7155553, 7+1+5+5+5+5+3 = 31

7735531, 7+7+3+5+5+3+1 = 31

7375531, 7+3+7+5+5+3+1 = 31

7335931, 7+3+3+5+9+3+1 = 31
