Answer:

x = -4

Step-by-step explanation:

let x equal the number

so

1/4(-x)+2=1/2(-x)+4

-1/4x + 2 = -1/2x + 4

+1/2x          +1/2x

1/2x + 2 = 4

        -2    -2

1/2x = 2

x = -4

Answer: x=-8

Step-by-step explanation:

1/4x+2=2x+16

Multiply by four to get rid of the fractions

X+8=2x+16

Combine like terms

-x=8

x=-8

Answer:

C.)

Step-by-step explanation:

Add the area if the rectangle, to the area of the two semi-circles.

Area of Rectangle: L: 6[tex]\frac{5}{8}[/tex] in times W: 8 in = 53 in

Area of Semi-circle: [tex]\frac{1}{2}[/tex](πr2): [tex]\frac{1}{2}[/tex](π(4)2) = 25.13  

(r is always half of diameter (d) so r=4)

53 + 25.13 + 25.13 = 103.26

Answer:

so Area of Outer part = 8x + 16 square inches

Step-by-step explanation:

2 squares.

inner square dimension is x inches by x inches.

width of outer region= 2inches.

We want the area of the border around the inner square.

so

Area of border = B = Area of Large - Area of Inner

B = (x+4)^2 - x^2

B = x^2 + 8x + 16 - x^2

B = 8x + 16 square inches

so Area of Outer part = 8x + 16 square inches

Answer:

Step-by-step explanation:

Zero represents sea level.

15 is above sea level because it’s a above 0.

-25 is below sea level because it’s below 0.

Second pic

Zero represents negative and positive degrees ( not sure how to word it )

-5 degrees is below average because it’s below 0.

55 degrees is above average because it’s above 0.

Third pic

Zero represents average temperature

-30 degrees is below average because it’s below 0

70 degrees is above average because it’s above 0

Fourth pic

Zero represents sea level

-10 feet is below sea level because it’s below 0

20 feet is above sea level because it’s above 0

Answer

Y= 2 x= -0.645

Step-by-step explanation:

you basically plug 0 into x and y

y=1.29(0)+ 2

y=2

0=1.29x+ 2

Answer:

Okay so "y = mx+b is a linear equation that represents a line on a graph; m represents the slope of the line and b is the y-intercept (The y-intercept of this line is the value of y at the point where the line crosses the y axis.)

In y = 1.29x+2, 1.29 is equal to m, so that is your slope.

The 2 is equal to the b so your y-intercept is 2.

Here's a  graph to better understand it :)

Answer:

4.5

Step-by-step explanation:

as the summation of all angles in a triangle must be 180

∠H = 180 - (130 +20)

       = 180-150

         =30

as the straight line has an angle of 180

∠G= 180 - 130

       = 50

since that

∠f = 180- (50+60)

    =180- 110

    =70

answer is C

Answer: Ben can only rent the boat for 5 hours.

Step-by-step explanation:

You have to set up an equation. It would be 20 + 12h = 80

20+12x=80

12x=80-20

Then divide both sides 12x=60

And you get 5

Answer:

2?

Step-by-step explanation:

i think its 2 because 1 is an odd number and it goes 1,1 ( two odd numbers) then __ 3,5 ( two more odd numbers then 8,13,21( even number then two more odd numbers) the 34( even number). i'm thinking the pattern is odd, odd, even, odd, odd, even, odd odd, even.

Answer:

84%

Step-by-step explanation:

Completed passes: 21

total: 25

fraction: 21/25

21/25 x100

= 84

He has completed 84% of passes.

Answer: 84%

Step-by-step explanation:

1. Convert each number to 100% to make it easier to work out.

2. Multiply 25 x 4 to get to 100, and 21 x 4.

3. 21 x 4=84.

4. So, Grady had completed 84% of the passes.

Answer:

Step-by-step explanation:

f(n)=30n

domain all real numbers

range all real numbers

I think.

Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.

A relation is a function if it has only One y-value for each x-value.

The function that relates the total number of minutes practiced, p, to the number of practice days, n, is given by:

p = 30n

where 30 is the number of minutes Elena practices each day.

Since we cannot have negative practice days, the domain of the function is the set of non-negative integers:

Domain: {0, 1, 2, 3, ...}

The range of this function is the set of all possible values of p that can be obtained by plugging in values of n from the domain.

In this case, since the function only outputs non-negative values, the range is the set of non-negative integers:

Range: {0, 30, 60, 90, ...}

Hence, Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.
