Do you have answer choices or are they just fill in?
Answer:
x = 60
Step-by-step explanation:
We have, 45% • x = 27
or,
45
/100 • x = 27
Multiplying both sides by 100 and dividing both sides by 45,
we have x = 27 • 100/
45
x = 60
Step-by-step explanation:
It gained 15 minutes in 36 hours.
15/36 = x/24
36x = 360
x = 10 minutes
Insert the point, (5,-2) with the slope of the line to figure out the equation. You can either use point-slope form, or plug it for for slope-intercept form.
Slope-intercept form:
-2 = -2(5) + b
-2 = -10 + b
Add 10 on both sides
8 = b
Thus,
y = -2x + 8
Answer is B
Answer:
(2, -5)
Step-by-step explanation:
Convert to vertex form:
3x^2 - 12x + 7
= 3(x^2 - 4x) + 7
Completing the square:
= 3[ (x - 2)^2 - 4)] + 7
= 3(x - 2)^2 - 12 + 7
= 3(x - 2)^2 - 5.
Comparing with the general form
a(x - b)^2 + c we see that the vertex is (b, c) = (2, -5).
