19. Mariella is driving a distance of 100 miles. She drives at a constant rate of 60 miles per hour. The equation that represents the distance she has
left to go is y= 100 – 60x, where x is the number of hours she has
already driven.
a. Graph the equation.
b. State the slope and the y-intercept of the graph from part a.
c. Reason abstractly. Explain what the slope and y-intercept of the
line represent in this item.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i
