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.

Answer:
The first piece is 5 inches long, while the second is 15 inches and the third one is 20 inches.
Step-by-step explanation:
To determine the length of the 3 pieces, knowing that the total of the board is 40 inches, and that the second measures 3 times more than the first and the third measures 4 times more than the first, the following equation must be performed:
X + 3X + 4X = 40
8X = 40
X = 40/8
X = 5
Therefore, the first piece is 5 inches long, while the second is 15 inches and the third 20 inches.
Answer:
-2
Step-by-step explanation:
Step 1. Copy the given expression.
(a + y)^2 + 2y =
Step 2. Replace each variable by the value given.
We are given a = 5; y = -3.
= (5 + (-3))^2 + 2(-3)
Evaluate the expression using the correct order of operations.
= (2)^2 - 6
= 4 - 6
= -2
A linear pattern is when the points form a straight line. For example the following points follow a linear pattern: (0, 0), (1, 2), (2,4), (3,6). These points are all increasing by the same amount. X is increasing by 1 while Y increases by 2.
A non-linear pattern can pretty much be anything that doesn't follow an exact rule. Like: (0,1) (4,3), (6, 12), (7,9). These points would not form a straight line, it would just be a bunch of random points everywhere.

Answer:
x-intercept: x = -4/3
Step-by-step explanation:
x-intercept when y = 0
-6x + 0 = 8
so
-6x = 8
x = 8/-6
x = -4/3
