Maria created a graph of b(t), the temperature over time. for the interval between t = 3 and t = 7, the average rate of change in her graph of b(t) is 8. which statement must be true?
a. the temperature was 8 degrees higher when t = 7 than when t = 3.
b. the temperature was 8 times higher when t = 7 than when t = 3.
c. the temperature was 32 degrees higher when t = 7 than when t = 3.
d. the temperature was 2 degrees higher when t = 7 than when t = 3.

Which statement accurately explains whether a reflection over the y-axis and a 270° counterclockwise rotation would map figure acb onto itself? a coordinate plane with figure acb with point a at 1, 1, c at 3, 4 and b at 5, 1 yes, a″c″b″ is located at a″(1, 1), c″(4, 3), and b″(1, 5) yes, a″c″b′ is located at a″(1, 1), c″(3, 4), and b″(5, 1) no, a″c″b″ is located at a″(1, 1), c″(4, 3), and b″(1, 5) no, a″c″b″ is located at a″(1, 1), c″(3, 4), and b″(5, 1)

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"

Aquadratic equation in standard from is written ax^2= bx+c, where a, b and c are real numbers and a is not zero?
