Answer:
x = 8.4
y = -2
Step-by-step explanation:
Step 1: Sub y=-2 into y=5x + 40
-2 = 5x + 40
Step 2: Solve for 'x'
-2 = 5x +40
-42 = 5x
x = 42/5
x = 8.4
Step 3: Solve for 'y'
y is given in the question, y=-2
Whether it can be equal to that value. For example, if 5 is greater than x, then an open circle will be useful. If 5 is greater than or equal to x, a closed circle will be used.
10 square units.
The quadrilateral is 2 x 2 = 4
Triangle a 2 x 2 = 4; divided by 2 = 2
Triangle b 4 x 2 = 8; divided by 2 4
4 + 2 + 4 = 10 units squared
