Answer:
(-3, 0), (0, -9)
Step-by-step explanation:
x-intercept: Let y = 0 and find x: 0 = -3x - 9), or 3x = -9. Then x = -3, and the x-intercept is (-3, 0).
y-intercept. Let x = 0 and find y. y = -3(0) - 9 = -9. The y-intercept is (0, -9).
Your answer would be 18.39
And here's why:
Behind the decimal your numbers are in the following places.
The (3) is in the tenths place.
The (8) is in the hundredths place.
And the (6) is in the thousandths place.
Whatever number is AFTER the place your rounding, is going to help you out.
If the number is 1-4, you round down.
If the number is 5-9, you round up.
Hope this helps! (:
Answer:
(x - 5)² + (y + 3)² = 16
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (5, - 3) and r = 4, so
(x - 5)² + (y - (- 3))² = 4², that is
(x - 5)² + (y + 3)² = 16
Answer:
B
Step-by-step explanation:
The area between the curves y = d and y = f(x), between the limits x=a and x=b, is:
∫ₐᵇ (d − f(x)) dx
Alternatively, the area between the curves x = f(y) and x = a, between the limits y = c and y = d, is:
∫ᵈ (f(y) − a) dy
Answer A would give you the area between x = f(y) and the y-axis. It needs to include the − a term to be correct.
Answer:
Since we have g(4) just replace every x with 4:
g(4) = (4² -6)/(3×4 + 10)
= (16 - 6)/(12 + 10)
= 10/22 = 5/11
