4m -21 = 3(5m - 1) 
4m - 21 = 15m - 3
15m - 4m = -21 + 3
11m = -18
m = -18/11

To check: 
LHS → 4 (-18/11)  -21 = - 303/11
RHS → 3( 5(-18/11) - 1) = -303/11
LHS = RHS (The answer is right)

8t+12s=180 and t=3s is the system of equations that represents the given scenario.

Step-by-step explanation:

Given,

Cost of a t-shirt = $8

Cost of a shorts = $12

t-shirt = t

shorts = s

Revenue earned = $180

According to given statement;

8t+12s=180

The store sold three times as many T- shirts as shorts.

t = 3s

8t+12s=180 and t=3s is the system of equations that represents the given scenario.

Find the x-intercepts if the parabola with vertex (-3,-18) and y-intercept (0,0). Write your answer
anzhelika [568]
Vertex form is 
y = a(x - b)^2 + c

here a = -3 and b = -18 so we have

y = a(x + 3)^2 - 18

when x = 0 , y= 0  ( the y-intercept) so:-

0 = a(3^)2 - 18
9a = 18 
a = 2

so the parabola  is y = 2(x + 3)^2 - 18

x intercepts found as follows:-

2(x + 3)^2 - 18 = 0
(x + 3)^2 = 9
x + 3 =  +/- sqrt9  = +/- 3

so x intercepts  are 0 and -6 Answer
