Answer:
73.5
Step-by-step explanation:
y=kx
where k is a constant
y=7
x=2
7=2k
k=3.5
what about when x=21
y=3.5*21
y=73.5
Q1: y = -3/2x +1
Q2: The graph changes vertically from -1 to 3 (4 units) at the same time it changes horizontally from -4 to 1/2 (4.5 units). The rate of change is 4/4.5 = 8/9 ≈ 0.8889. The closest answer selection is 9/10.
Q3: x=-2
Q4: The graph changes vertically by -4 at the same time it changes horizontally by +1. The slope is 4/-1 = -4. The y-intercept is +1, so the equation is
.. y = -4x +1
Q5: After the same pattern as above,
.. y = 5/2*x +5
Y=-1x+2 I think .................
Answer:
x = 2
Step-by-step explanation:
f(x) is the range and values of x the domain
When f(x) = 4 the corresponding value of x in the domain is x = 2
Answer:
(-12, -10)
Step-by-step explanation:
Midpoint M is the average of endpoints A and B:
M = (A +B)/2
2M = A + B . . . . . . multiply by 2; next, subtract A
B = 2M - A . . . . . . the missing endpoint can be found this way
B = 2(-8, 0) -(-4, 10) = (2(-8)+4, 2(0)-10) = (-12, -10)
