For part A add up all your students then add up all your students that like bike riding and skating (80+90) divide that by the total number of students who took the survey
For Part be put 20+40 over the toatl number of student then simplify
Answer:
y = -5/4x - 7
Step-by-step explanation:
First, find the slope:
3 - -7 / -8 - 0 = -5/4
Put it in point slope form:
y + 7 = -5/4(x-0)
y + 7 = -5/4x
y = -5/4x - 7
(2, -4) → x = 2, y = -4
Put the coordinates of the point to the inequality.
y < x - 2 → -4 < 2 - 2 → -4 < 0 TRUE
y ≥ -x -4 → -4 ≥ -2 - 2 → -4 ≥ -4 TRUE
Answer:
You can check other systems.
(2) y > x - 2 → -4 > 2 - 2 → -4 > 0 FALSE
(3) y ≤ -x - 4 → -4 ≤ -2 - 4 → -4 ≤ -6 FALSE
(4) y > x - 2 → -4 > 2 - 2 → -4 > 0 FALSE
Step-by-step explanation:
f(x) = x² + 2x - 4
g(x) = 3x + 1
f(g(x)) = f(3x + 1)
f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4
= 9x² + 6x + 1 + 6x + 2 - 4
= 9x² + 12x -1
Answer:
(9/2, 9/2)
Step-by-step explanation:
midpoint formula = (x1 + x2/2, y1 + y2/2)
(7,6) is x1 and y1.
(2,3) is x2 and y2.
Solve:
x-coordinate= (7+2)/2 = 9/2 or 4.5
y-coordinate= (6+3)/2 = 9/2 or 4.5
your final answer is (9/2, 9/2)
decimal form = (4.5, 4.5)
