Answer:
m<-5
Step-by-step explanation:
Answer: The number was incorrectly converted.
Explanation: The error is in the sign of the power: -9
While , the power should have been positive 9 because
So the correct conversion is as follows:
Answer:
8x^2 +5x -3
Step-by-step explanation:
(3x^2-2)+(5x^2+5x-1)
I like to line them up vertically
3x^2 -2
+5x^2+5x-1
------------------------
8x^2 +5x -3
1. num of minutes 2,

4 he ran faster in the last two minutes
5. yes because it passes the vertial line test. it is linear
Answer:
x = (-1/4)(1 ± √33)
Step-by-step explanation:
Let's "complete the square."
This procedure requires taking half of the coefficient of x and squaring it:
Half of 1/2 is 1/4, and the square of 1/4 is 1/16.
Then we have:
x^2 + (1/2)x + 1/16 = 2 + 1/16 = 33/16
Rewriting x^2 + (1/2)x + 1/16 as the square of a binomial, we get:
(x + 1/4)^2 = 33/16
We must solve this for x.
Taking the sqrt of both sides, we get:
x + 1/4 = ±√33/4, or:
x = -1/4 ±√33/4, or
x = (-1/4)(1 ± √33)
