Answer:

x = 2.5

Step-by-step explanation:

2x - 11 = -8x + 14

Add 8x to both sides

10x - 11 = 14

Add 11 to both sides

10x = 25

Divide both sides by 10

x = 2.5

Please help me this is due today
Serjik [45]

Answer:

1. 15 (A)

2. 12 (G)

Step-by-step explanation:

1.  We can make an equation out of this...

    3x+3=48

    x is the age of Geoff which is what we are trying to find out

   

    We have to add 3 to both sides of the equation

    3x+3=48

         -3   -3

     ________

    we end up with 3x=45

     we then have to divide 3 by both sides because its the opposite of                

     multipling

    3x=45

    _____

         3

    we get x=15

2.   We can write a problem statement  

      (2 x 9)-6=?

       multiply 2 and 9 <u>FIRST</u>

     

       18-6=?

       your answer is 12

      Your Welcome! Have a great rest of your day! :)

PLEASE HELP WILL MARK BRAINLIEST!!!!

1.

(a) The variables are:

→ y is the total cost

→ x is the number of ride tickets

→ c is the price of the fair admission

(b) The linear equation that can be used to determine the cost for

anyone who only pays for ride tickets and fair admission is

y = 1.25 x + c

(c) Because the equation is linear which means the value of y depends on

the value of x and the value of c = 5 does not change so the equation

can be used to determine the cost for anyone who only pays for ride

tickets and fair admission

2.

(a) The slope of the line is \frac{3}{4}

(b) The equation of the line in point-slope form is:

y - 3 = \frac{3}{4} (x + 4)

(c) The equation of the line in slope-intercept form is:

y = \frac{3}{4} x + 6

3.

The inequality that model the problem is:

20x + 10y ≥ 2000

Step-by-step explanation:

1.

The given is:

1. The county fair charges $1.25 per ticket for the rides.

2. Jermaine bought 20 tickets for the rides and spent a total of $35.00

    at the fair

3. Jermaine spent his money only on ride tickets and fair admission

4. The price of the fair admission is the same for everyone

Use y to represent the total cost and x to represent the number of

ride tickets

∵ The price of a ticket = $1.25

∵ The number of tickets = x

∵ y represents the total cost

∵ The total cost = the cost of a ticket × the number of tickets + the price

   of the fair admission

∴ y = 1.25 x + c, where c is the fair admission

∵ Jermaine bought 20 tickets

∴ x = 20

∵ Jermaine spent a total of $35.00 at the fair

∴ y = 35

- Substitute these values in the equation in step b

∴ 35 = 1.25(20) + c

∴ 35 = 25 + c

- Subtract 25 from both sides

∴ c = 5

∵ c represents a constant term (y-intercept) in the linear equation

∴ The price of the fair admission for any one is $5

(a)

The variables are:

→ y is the total cost

→ x is the number of ride tickets

→ c is the price of the fair admission

(b)

The linear equation that can be used to determine the cost for

anyone who only pays for ride tickets and fair admission is

y = 1.25 x + 5

(c)

Because the equation is linear which means the value of y depends on

the value of x and the value of c = 5 does not change so the equation

can be used to determine the cost for anyone who only pays for ride

tickets and fair admission

2.

A line goes through the points (-4 , 3) and (4 , 9)

The rule of the slope of a line is m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

∵ x_{1} = -4 and x_{2} = 4

∵ y_{1} = 3 and y_{2} = 9

∴ m=\frac{9-3}{4--4}=\frac{6}{8}=\frac{3}{4}

(a)

The slope of the line is \frac{3}{4}

(b)

The point-slope form of the equation is y-y_{1}=m(x-x_{1})

∵ y_{1} = 3 and x_{1} = -4

∵ m = \frac{3}{4}

∴ y - 3 = \frac{3}{4} (x - -4)

∴ y - 3 = \frac{3}{4} (x + 4)

The equation of the line in point-slope form is:

y - 3 = \frac{3}{4} (x + 4)

(c)

The slope-intercept form of the equation is y = mx + c, where c is the

y-intercept

∵ m = \frac{3}{4}

∴ y = \frac{3}{4} x + c

- To find c substitute x and y by the coordinates of one of the two

  given points

∵ x and y are the coordinates of point (4 , 9)

∴ 9 = \frac{3}{4} (4) + c

∴ 9 = 3 + c

- Subtract 3 from both sides

∴ c = 6

∴ y = \frac{3}{4} x + 6

The equation of the line in slope-intercept form is:

y = \frac{3}{4} x + 6

Jacob and Sarah are saving money to go on a trip

The given is:

1. They need at least $2000 in order to go

2. Jacob mows lawns and Sarah walks dogs to raise money

3. Jacob charges $20 each time he mows a lawn and Sarah charges

   $10 each time she walks a dog

4. x representing the number of lawns mowed and y representing the

   number of dogs walked

∵ x representing the number of lawns mowed

∵ Jacob charges $20 each time he mows a lawn

∴ Jacob can earn $20x

∵ y representing the number of dogs walked

∵ Sarah charges $10 each time she walks a dog

∴ Sarah can earn 10y

∵ They need at least $2000 in order to go to the trip

∴ 20x + 10y ≥ 2000

The inequality that model the problem is:

20x + 10y ≥ 2000

Which equation describes the relationship of the<br> graphs of f(x) and g(x)?
I am Lyosha [343]

Answer:

Depends on which function is which...

Step-by-step explanation:

The blue graph is the same as the yellow graph but raised up 1 unit. That means either:

blue function rule = yellow function rule + 1

or

yellow function rule = blue function rule - 1

Your picture doesn't say which function is  <em>f</em>  and which is <em>g</em>.

If, just to pick a possibility, the blue function is <em>g</em>(<em>x</em>), then

g(x) = f(x) + 1

If the blue function is <em>f</em>(<em>x</em>), then

g(x) = f(x) - 1

Twenty five percent of this square is shaded what percent of the square is not shaded
Dominik [7]

Answer:

75%

Step-by-step explanation:

If 25 percent of a square is shaded, that means that the rest of the square is not shaded. We want an answer that we can add to 25 to get 100. So this means that 75% of the square is not shaded.
