Answer:
3
Step-by-step explanation:
Looking at the first three values of the table- when the x increases by 1, the y increases by 3.
If Rita has driven 30 miles so far (three-fifths of the way home), you can calculate what is the total length of her drive using the following steps:
x ... total length
three-fifths of the way home = 30 miles
3/5 of x = 30 miles
3/5 * x = 30 /*5/3
x = 30 * 5/3
x = 50 miles
The total length of her drive is 50 miles.
Answer: 39
Step-by-step explanation: you have to plug in -4 into each x so that would be f(-4)=2(-4)(2)+7(-4)(3)-8(-4)(2)-21(-4)+7= 39
hello :
y = 2(x + 3)² - 5
y = 2(x²+6x+9) -5
y = 2x² +12x +13...(answer : A) y=2x^2+12x+13 )
Option (a) is correct.
The standard form the equation is
Step-by-step explanation:
