Bryan’s monthly electric bill is determined by adding a flat administration fee to the product of the number of kilowatt hours of electricity used and the cost per kilowatt hour. When he uses 1,100 kilowatt hours of electricity, his bill is $113. When he uses 1,500 kilowatt hours of electricity, his bill is $153. What is the monthly administration fee? $

Answer:

[tex]y=-4x^{2} +7x+6\\[/tex]

Step-by-step explanation:

[tex]y=ax^{2} +bx+c\\[/tex]

Points are (1,9), (2,4), and (4,-30).

[tex]\\9=a+b+c\\4=4a+2b+c\\-30=16a+4b+c\\[/tex]

Subtract the first from the second.

-5 = 3a+b

Subtract 4 times the second from the third.

-34=12a+2b

-14=-2b

b=7

a=-4

c=6

Answer:

32 Nickels

Step-by-step explanation:

Given

Coins: Nickels (N) and Dimes (D)

$0.05 = 1 nickel and $0.10 = 1 dime

So, the amount implies:

[tex]0.05N + 0.10D = 6.20[/tex]

The number of coin implies:

[tex]D = 14 + N[/tex]

Required

Determine the number of nickels found

Substitute 14 + N for D in [tex]0.05N + 0.10D = 6.20[/tex]

[tex]0.05N + 0.10(14 + N) = 6.20[/tex]

[tex]0.05N + 1.4 + 0.10N = 6.20[/tex]

Collect Like Terms

[tex]0.05N + 0.10N = 6.20 - 1.4[/tex]

[tex]0.15N = 4.8[/tex]

Solve for N

[tex]N = 4.8/0.15[/tex]

[tex]N = 32[/tex]

Hence, he found 32 nickels

Answer:2x-5y=-15

Step-by-step explanation:

Answer:

  y  = 12

Step-by-step explanation:

The equation of the expression is given as;

              2y  = 24

We are to write in slope form';

    In slope form, an equation is expressed as;

             y = mx + c

where y and x are the intercept

               m is the slope

                c is the intercept

Now to write 2y = 24 in intercept form, we have;

                 2y  = 24

  divide both sides by 2;

                y  = 12

f(-4)=5(2-3(-4)

f(-4)=10+60

f(-4)=70

Answer:

y = 9

Step-by-step explanation:

Collect the like terms:

2y = 18

Divide both sides by 2 to make y on its own

y = 9

Answer:

y = 5/24

Step-by-step explanation:

2/3 = 24/36

3/4 = 27/36

8/9 = 32/36

32-27 = 5

5/36 / 2/3 = 15/72 = 5/24

Answer:y=5/13

Step-by-step explanation:

8/9-3/4 is 5/36

divide by 2/3 is

Answer:

The piecewise function is shown in the graph is

Step-by-step explanation:

At first, you must find the equation of each line

The form of the equation of the line is f(x) = m x + b, where

From the graph

∵ The line to the left intersects the y-axis at point (0, 1)

∴ b = 1

∵ The line passes through points (0, 1) and (-2, 2)

∴ Δx = -2 - 0 = -2

∴ Δy = 2 - 1 = 1

→ Use them to find the value of m

∵ m = Δy/Δx

∴ m = [tex]\frac{1}{-2}[/tex]

∴ m = -0.5

→ Substitute the values of m and b in the form of the equation above

∴ f(x) = -0.5x + 1

∵ The domain of the function is the values of x

∵ The line starts with an empty circle

→ That means x = 0 does not belong to the domain

∴ The sign of inequality is < without equal

∴ The domain of f(x) is x < 0 ⇒ all values less than 0

∵ We have only one answer has f(x) = -0.5x + 1, x < 0

∴ The graph represents the first answer A

∴ The piecewise function is shown in the graph is

The drawing states that we are looking for the height of the tree.

h = unknown

horizontal length = 26

∅ = 24°

We will have to use tangent to solve for the missing length

Step 2: Solve for h

Answer:

300

Step-by-step explanation:

Evaluate 2 y^2 (y + x) where x = 1 and y = 5:

2 y^2 (y + x) = 2×5^2 (1 + 5)

Hint: | Evaluate 1 + 5.

1 + 5 = 6:

2×5^2×6

Hint: | Evaluate 5^2.

5^2 = 25:

2×25×6

Hint: | Multiply 2 and 25 together.

2×25 = 50:

50×6

Hint: | Multiply 50 and 6 together.

50×6 = 300:

Answer: 300

Step-by-step explanation:

we multiply both sides by the denominator on the right to eliminate fraction, so we have..

p*(n+a)= (n²+a/n+a)*n+a

so we have

p(n+a)= n²+a

so opening the bracket on the left hand side we have,

p*n+p*a

pn+pa

so,

pn+pa= n²+a

so collecting like terms we have,

pn-n²= a-pa

so removing a from the equation on the right hand side we have,

pn-n²=a(1-p)

dividing both sides by the equation in the bracket on the right hand side, we have..

pn-n²/(1-p)= a

a = pn-n²/1-p

or

a = n(p-n)/1-p
