Step-by-step explanation:
On the graph, when y=0 find the x intercept.
The y=0 the x is at 1 and 3 so the first one is
(1,0)
and the second one is
(3,0)
Answer: 5.39 hours
Step-by-step explanation:
For Jill:
Number of hours used = 8.4 hours
Number of bushels of apples picked = 40
Number of bushels of apples picked per hour will be: = 40/8.4 = 4.7619
For Maria:
Number of hours used = 15 hours
Number of bushels of apples picked = 40
Number of bushels of apples picked per hour will be: = 40/15 = 2.6667
We then add the number of bushels of apples picked per hour for both of them together. This will be:
= 4.7619 + 2.6667
= 7.4286
If they worked together, the hours they'll take to pick 40 bushel of apples will be:
= 40/7.4286
= 5.39 hours
Hello from MrBillDoesMath!
Answer: Choice C, -(3 +2/3)
Discussion:
Start with
13x^2 + 56x + 75 = 4x^2 -10x - 46
Subtract 4x^2 from both sides:
(13x^2 - 4x^2) + 56x + 75 = -10x - 46
Add 10x to both sides
(13x^2 - 4x^2) + (56x + 10x) + 75 = (-10x + 10x) - 46 or
9x^2 + 66x + 75 = -46.
Add 46 to each side
9x^2 +66x + (75 + 46) = 0 =>
9x^2 + 66x + 121 = 0.
This factors as follows:
9x^2 + 66x + 121 = (3x + 11)^2 = 0 =>
3x + 11 = 0 =>
x = -11/3 = - (3 + (2/3)) which is choice C
Thank you,

We know that
A direct variation is a<span> mathematical relationship between two variables that can be expressed by an equation
</span>y=kx
the rate of change is equal to the slope of a line
k=m
step 1
Find the slope of the graph
let
A(0,0)
B(10,50)
m=(y2-y1)/(x2-x1)------> m=(50-0)/(10-0)------> m=50/10-----> m=5
therefore
the equation is
y=5x
the answer is
the rate of change is 5
17/8 + 3/8 = 20/8
y = 20/8
Hope This Helps You!
Good Luck Studying :)
