find the vertex form of 4x^2+8x-8
Answers
Answer:
4(x + 1)^2 - 12.
Step-by-step explanation:
f(x) = 4x^2 + 8x - 8
f(x) = 4(x^2 + 2x) - 8
f(x) = 4[(x + 1)^2 - 1) - 8
f(x) = 4(x + 1)^2 - 4 - 8
f(x) = 4(x + 1)^2 - 12.
Water makes up about 60% of the average adult's body weight. Represent this percent by shading in the squares.
Answers
Answer:
shading three boxes
Step-by-step explanation:
It is given that :
The body weight of an average adult = 60%
We have to show this by shading the square boxes shown.
There are 5 square boxes in total which makes up 100%.
So divide 100 by 5, we can 20% for each box.
So, 20% + 20% + 20% will give us 60%
Therefore, shading three boxes will give us 60% which is the water percent in an average adult's body weight.

On a recent survey, 40% of the 900 people surveyed preferred running.
How many people preferred running?
Answers
Answer: 550
Explanation:
Well first, you need to solve 40 percent of 900 (which is 360) then subtract it from the main amount (900)
So 900-360
Answer:
360
Step-by-step explanation:
So we have 40% and 900 people. Before we ask ourselves what is 40 percent of 900, lets ask ourselves what is 10 percent. So 10 percent of 900 would be 90 because you have to move the decimal point 1 unit to the left.
Now, 40 percent is 4 times the value of 10 percent so 40 percent of 900 has to be 360, because 90 times 4 is 360.
And you can check it by multiplying 900 x .40 which would be 360

carpenter has a board that is 8 feet long. e cuts off two pieces. One piece is 32 feet ug and the other is 2 feet long. How ch of the board is left?
Answers
Answer:
2 1/6 feet
Step-by-step explanation:
A carpenter has a board that is 8 feet long. He cuts off two pieces. One piece is 3 1/2 feet long and the other is 2 1/3 feet long. How much of the board is left?
Total length of the board = 8 feet
Piece A = 3 1/2 feet
Piece B = 2 1/3 feet
Piece A + piece B
= 3 1/2 feet + 2 1/3 feet
= 7/2 + 7/3
= (21+14) / 6
= 35/6
= 5 5/6 feet
Length of the board remaining = Total length of the board - length of the two pieces
= 8 feet - 35/6 feet
= (48-35) / 6
= 13/6 feet
= 2 1/6 feet
Length of the board remaining = 2 1/6 feet

Answers
Answer:
x = -5 y = -5
Step-by-step explanation:
–x + 4y = -15
- 4y -4y
-1(-x = -4y - 15)
x = 4y + 15
Substitute x = 4y + 15 into 3x + 5y = -40
3(4y + 15) = -40
17y + 45 = -40
- 45 -45
17y = -85
/ 17 /17
y= -5
Substitute y = - 5 into x = 4y + 15:
x = 4(-5) + 15
x = -20 + 15
x = -5
Answer:
Part I
(-5,-5)
Part II
(3.75, 312.50)
Step-by-step explanation:
Part I
(1) 3x + 5y = -40
(2) -x + 4y = -15
solve for x in (2)
x = 15 + 4y
substitute into (1)
3(15+4y) + 5y = -40
45 +12y + 5y = -40
45 +17y = -40
17y = -85
y = -5
substitute y = -5 into (1)
3x + 5(-5) = -40
3x -25 = -40
3x = -15
x = -5
so (-5, -5)
Part II
Studio A
C = 125 + 50t
Studio B
C = 200 + 30t
125 + 50t = 200 + 30t
20t = 75
t = 3.75
