Answer:
7.(1,0) and (-4,0)
8. (-3,0) and (-2,0)
Step-by-step explanation:
7.
When the function is equal to zero, we are looking for the zeros, or the x intercepts
Where it crosses the x axis are 1 and -4
(1,0) and (-4,0)
8. When the function is equal to zero, we are looking for the zeros, or the x intercepts
Where it crosses the x axis are -3 and -2
(-3,0) and (-2,0)
Answer:
3 cups
Step-by-step explanation:
we can solve this by setting up ratios
cross multiply:
solve for x
Answer:
Width = 5
Length = 2*5 = 10
Step-by-step explanation:
Givens
Let the width = W = x
Let the length = L = 2x
Equation
Area = L * W
Solution
Area = 2W * W Substitute into the given equation
Area = 2W^2 Simplify the right
50 = 2W^2 Divide by 2
50/2 = 2W^2 / 2 Simplify
25 = W^2 Switch
W^2 = 25 Take the square root of both sides
sqrt(w^2) = sqrt(25)
Answers
w = 5 ft
L = 2 * 5 = 10 ft
Answer:
Mapping A
Step-by-step explanation:
To clarify this, the first box in each mapping has to go to only one number to resemble a function. Function A works because each number is going to another number once while Function B doesn't work because of the number 2 going into two numbers.
