Let the money spent by John = y
and Amy=x
ATQ
x+y = $29
It is given that jon spend 5 more than Amy. SO he spend
x +5
x+y = $29
x+x+5=$29
2x = 29-5
2x= 24
x = 24/2 =12
So Amy spend $ 12 and Jon spend x+5 = 12+5 = $17
Hello there!
The answer is C.
I will explain to you how I came to this answer.
•First of all, I counted the turning points. There are two, so that means this polynomial function has THREE roots. (# of turning points+1=number of roots.)
•Next, look to see how many times the function crosses the x-axis. This is the number of REAL solutions. In this case, there is one point at which the f(x) is crossing the x-axis so there is one real solution.
•Since there is one real solution there has to be 2 imaginary roots. (Total # of solutions-real solutions=imaginary solutions)
NOTE: the turning points are where the increasing intervals change to decreasing and the decreasing change to increasing. The first derivative at these points is 0.
I hope this helps!
Best wishes~

Answer:
Step-by-step explanation:
SA = bottom rectangle area+side rectangle area + slant rectangle area + 2 triangles
= 26(36) + 10(36)+36(28) +2(0.5)(10)(26) = 2564 cm2
I guess its 40 meters since
Area of a square is (Length)^2
and The area is 100, so square root that and you get your length which is 10 meters.
and since perimeter is the sum of lengths of sides, and a square has 4 sides, your perimeter is 40 meters! :)
Answer:
y = 9x + 10
Step-by-step explanation:
y = mx + b
Here, m is slope and b is y-intercept
y = 9x + 10
