A mountain road is 5 miles long and gains elevation at a constant rate. After 2 miles, the elevation is 5500 feet above sea leve
l. After 4 miles, the elevation is 6200 feet above sea level.
What would be the equation of this line?
Find the elevation of the road at the point where the road begins.
Describe where you would see the point in part (a) on a graph where represents the elevation in feet and represents the distance along the road in miles.

Answer:
The temperature of the part won’t reach or exceed 141℉
Step-by-step explanation:
Substituting the value of T= 141 the given equation becomes
we know that discriminant D =
Three conditions: - D < 0: imaginary roots, D = 0: real and equal roots,
D > 0: two real and unequal roots Substituting a = -0.005, b = 0.045 and c = -16, Therefore, it won't reach the temperature.
Answer:
A'(-3, 5), B'(1, 7), C'(2, 3)
Step-by-step explanation:
The rule means to subtract 1 from all the <em>x</em>-coordinates and add 2 to all the <em>y</em>-coordinates. (It also means move each point 1 unit to the left and 2 units up.)
