Answer:
Step-by-step explanation:
20%, because if 65 is 100, then 52 is 80% out of 65; so 100 - 80 is 20
Answer:
D) x = 4, y = -2, z = 3
Step-by-step explanation:
x = 3z − 5
2x + 2z = y + 16
2(3z - 5) + 2z = y + 16
6z - 10 + 2z = y + 16
8z = y + 26 ---> (A)
7x − 5z = 3y + 19
7(3z - 5) - 5z = 3y + 19
21z - 35 - 5z = 3y + 19
16z = 3y + 54 ---> (B)
8z = y + 26
16z = 3y + 54
2(y + 26) = 3y + 54
2y + 52 = 3y + 54
y = -2
8z = -2 + 26
8z = 24
z = 3
x = 3(3) - 5
x = 4
5/6 x 2 3/4 = 5/6 x (2x4+3)/4 = 5/6 x 11/4 = 55/24 = 2 7/24
Answer:
Step-by-step explanation:
The functions are written in slope-intercept form.
The graph crosses the y-axis at (0,-2), so the y-intercept is -2.
You can eliminate D because its y-intercept is +2, not -2.
(1,1) and (0,-2) are points on the line.
The slope of the line is (-2-1)/(0-1) = 3
You can eliminate B because its slope is ⅓.
Eliminate C because its slope is -3, not 3.
Answer B
