Answer:
x = (-5 ± √57) / 2
Step-by-step explanation:
x² = 8 − 5x
x² + 5x − 8 = 0
Solve with quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -5 ± √(25 − 4(1)(-8)) ] / 2
x = (-5 ± √57) / 2
Answer:
answers are B,C and E
you got it right YAYYY !!!
good job haha
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
First you need to figure out what they multiplied 6 by to get 60, to do that reverse the operation to make it 60÷6=10. Then you multiply the 10 by the 2 to get 20.
Use the linear slope formula to solve for m:
m=(y2-y1)/(x2-x1)
using the points (-1,1) and (1,5) you can find the slope for the first interval:
m=(5-1)/(1-(-1))
m=4/2
m=2
you can double check by using the same formula on the second interval, which is (1,5) to (3,9).
m=(9-5)/(3-1)
m=4/2
m=2
therefore, the rate of change is 2.
