Answer:
24,6
Step-by-step explanation:
Answer:
x=-2
Step-by-step explanation:
The first step is to find the slope
m = (y2-y1)/ (x2-x1)
= (5-0)/(-2--2)
= (5-0) /(-2+2)
= 5/0
The slope is undefined
That means it is a vertical line (up and down) The x value does not change
x=-2
Let's find out.
David needs to score an average of 145 across all four games, so first we do:
145 × 4 = 580
Then we add all the scores he currently has:
139 + 143 + 144 = 426
Then we subtract 426 from 580 to find out how much he needs to score for his fourth:
580 - 426 = 154
David needs to score 154 on his 4th game to have an average score of 145 for all 4 games.
Answer:
A. x = 50, y = 130, z = 130
Step-by-step explanation:
50 and z are adjacent angles,
Sum of adjacent angles = 180,
50 + z = 180
z = 180 - 50
z = 130
z and x are adjacent angles,
Sum of adjacent angles = 180,
x + z = 180
130 + x = 180
x = 180 - 130
x = 50
z and y are opposite angles,
Opposite angles are equal in a parallelogram,
z = y = 130
Answer:
x ≥ 88
Step-by-step explanation:
In order to have at least an average of 80 after 4 tests, the sum of her scores must be at least 80 * 4 = 320 so we can write the following inequality:
71 + 78 + 83 + x ≥ 320
232 + x ≥ 320
x ≥ 88
