Answer:
Quadrant IV or D
Step-by-step explanation:
It is Quadrant IV or D, since it is a positive x (meaning it must be 1 or 4) and it has a negative y (so 3 or 4). You then find the common answer which is 4 or IV.
Answer:
x > 5
Step-by-step explanation:
14 - 3x < -1
-3x < -15
x > 5
He should tell Bill that depending on which side he wants the width or the length on, he should attach another board about 8 feet long to the 7 foot board since that is the length and he shouldnt attach anymore wood to the second board.
Answer:
(15/2, -5/2)
Step-by-step explanation:
1. Sub x=5y+20 into 2x+2y=10 and simplify as shown below.
2(5y+20)+2y=10
10y+40+2y=10
12y+40=10
12y=-30
y=-30/12
y=-5/2
2. Sub in y=-5/2 into 2x+2y=10 to find x and simplify as shown below.
2x+2(-5/2)=10
2x-5=10
2x=15
x=15/2
Answer:
100°
Step-by-step explanation:
I assume the image is the one attached below.
The shapes are quadrilaterals, so their interior angles add up to 360°. Three of those angles are 86°, 41°, and 133°. So the fourth angle is:
x + 86° + 41° + 133° = 360°
x = 100°
