2x + By = 15
We solve for y to put the equationj in the y = mx + b form in which b is the y-intercept.
By = -2x + 15
y = -2/Bx + 15/B
The y-intercept is 15/B, and we are told the y-intercept is 5.
15/B = 5
15 = 5B
B = 3
Answer: E. 3
Answer:

Answer:
Step-by-step explanation:
f(x) = x⁵ – 8x⁴ + 16x³
As x approaches +∞, the highest term, x⁵, approaches +∞.
As x approaches -∞, x⁵ approaches -∞ (a negative number raised to an odd exponent is also negative).
Now let's factor:
f(x) = x³ (x² – 8x + 16)
f(x) = x³ (x – 4)²
f(x) has roots at x=0 and x=4. x=4 is a repeated root (because it's squared), so the graph touches the x-axis but does not cross at x=4.
The graph crosses the x-axis at x=0.
Answer:
Juan got 18.50 miles per gallon.
Step-by-step explanation:
We are given the following in the question:
Odometer in the beginning of trip = 1460.3 miles
Odometer at the end of trip = 1830.2
Gallons of gas used for trip = 20 gallons
Distance of trip =
= Odometer at the end of trip - Odometer in the beginning of trip
Thus, the trip was of 369.9 miles.
Miles per gallon =
Thus, Juan got 18.50 miles per gallon.
