Step-by-step explanation:





x = 3 or x = -2 we dont use the (-2) because we have a sqrt
So x =3
Answer:
99
Step-by-step explanation:
Answer:
x=60
Step-by-step explanation:
Pick whichever equation where x=60 is true. I cannot see the other equations
Firstly you multiply 5 with everything in the brackets on the left side of = . and than you put t on the left side and change sign (if it was + then its going to be -) and numbers on right side and do the same with signs. then just calculate the rest
5(5t +1) = 25t - 7
25t + 5 = 25t - 7
25t - 25t = -7 + 5
0=-2
the statement is false
The rate of change for the points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
y=5x^2 and find the slope between x=-2 and x=6
y=6(-2)^2=6(4)=24
y=6(6)^2=6(36)=216
(-2,24)
(6,216)
slope=(216-24)/(6-(-2))=(192)/(6+2)=192/8=96/8=48/4=24/2=12
the rate of change is 12
