The problem ask to choose among the following functions in the given choices that has the greatest value and the best answer among the following function is letter D. a linear function that goes through point 2,0 and point 0,2. I hope you are satisfied with my answer
Answer:
34 m
Step-by-step explanation:
The proportion between sides AD and EH:
AD/EH = 1/2
must be also satisfied with the proportion:
AD/EH = DC/GH = 1/2
because they are corresponding sides between the two figures.
DC measures 17 meters, therefore:
GH = 17*2
GH = 34 m
This is a system of equations problem:
Part one set up general equations
1) Peanuts = 3x ($3 per pound)
2) Jellybean = 1.5y ($1.50 per pound)
Relate x and y to the information you have
He wants 30lb. total: x + y = 30
He also wants the mixture to be valued at $2.50 per pound = 3x + 1.5y = 30(2.5)
*I'm taking $2.50 times 30 because you want the total cost to equal since he wants $2.50 per pound.
You want to substitute one equation into the other.
x + y = 30
3x + 1.5y = 75
1) x + y = 30 => x = 30 - y
2) 3(30 - y) + 1.5y = 75
3) 90 - 3y + 1.5y = 75
4) -1.5y = -15
5) y = 10lb.
Then plug that into one of the original equations to get x.
6) x+ y = 30 => 10 + x = 30 => x = 20lb.
He wants 20lb. of peanuts and 10lb. of jellybeans
12x=-48 (divide 12 from both sides)
x=-4
10y-13y=30
-3y=30 (divide -3 from both sides)
-10=y
10x+14x=48
24x=48 (divide 24 from both sides)
x=2
Answer:
step 1. for time = 1, distance = 6.
step 2. if time = 4/3 then distance = 6(4/3) = 8
step 3. if distance = 9 then time = 9/6 = 3/2.
