Complete question :

Tom will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $57.98 and costs an additional $0.14 per mile driven. The second plan has an initial fee of $53.98 and costs an additional $0.16 per mile driven. How many miles would Tom need to drive for the two plans to cost the same?

Answer:

200 miles

Step-by-step explanation:

Let miles driven = x

First option :

57.98 + 0.14x

Second option :

53.98 + 0.16x

First option = second option

57.98 + 0.14 = 53.98 + 0.16x

57.98 - 53.98 = 0.16x - 0.14x

4 = 0.02x

x = 200

200 miles

Answer:

The formula of the geometric sequence is a[tex]_{n}[/tex] = [tex](-3)^{n-1}[/tex]

Step-by-step explanation:

The terms of the sequence are 1, -3, 9, -27

∵ -3 ÷ 1 = -3

∵ 9 ÷ -3 = -3

∵ -27 ÷ 9 = -3

∴ There is a common ratio between each two consecutive terms

∴ The sequence is geometric

∵ The formula of the geometric sequence is a[tex]_{n}[/tex] = a [tex]r^{n-1}[/tex], where

∵ The first term is 1

∴ a = 1

∵ The common ratio is -3

∴ r = -3

→ Substitute them in the formula above

∵ a[tex]_{n}[/tex] = (1) [tex](-3)^{n-1}[/tex]

∴ a[tex]_{n}[/tex] = [tex](-3)^{n-1}[/tex]

∴ The formula of the geometric sequence is a[tex]_{n}[/tex] = [tex](-3)^{n-1}[/tex]

Answer:

10 times 5 =50 (2.69 x 50) = 134.5

10 times 3=30 (1.21x30)= 36.3

Step-by-step explanation:

The difference between the area of Texas and Rhode Island in square miles and scientific notation should be (2.68 × 10⁵) square miles.

Area of Texas = (2.69 × 10⁵) square miles = 269000 square miles

Area of Rhode Island = (1.21 × 10³) square miles = 1210 square miles

Now

Difference between the Area of the Texas and Rhode Island should be

= 269000 - 1210

= 267,790 square miles

= (2.68 × 10⁵) square miles.

Answer:

A

Step-by-step explanation:

Answer:

point A (6,13) lies on the equation.  True

given point  B(21,33) lies on the equation.  True

given point  C (99, 137) lies on the equation.  True

The equation that was given was  y = 4/3x + 5

Now,check the given equation for the given points.

1)  A (6,13)

Substitute x = 6 in the given equation y = 4/3x +5

y = 4/3(6) + 5 = 4(2) + 5 = 8+5 = 13

y=13

the given point A (6,13) lies on the equation.

2)  B  (21,33)

Substitute x = 21 in the given equation y=4/3x+5

y=4/3(21) + 5 = 4(7) + 5=28+5=33

y = 33

the given point  B(21,33) lies on the equation.

3)  C (99, 137)

Substitute x = 99 in the given equation y = 4/3x + 5

y=4/3(99) + 5 = 4(33) + 5 = 132 + 5 = 137

y = 137

Answer:

The average rate of change is 76.8

Step-by-step explanation:

The average rate of change is ;

f(b)-f(a)/b-a

where ; a is 11 and b is 15

f(11) = 0.01(2)^11 = 20.48

f(15) = 0.01(2)^15 = 327.68

The average rate of change will

be;

(327.68-20.48)/15-11 = 307.2/4 = 76.8

Answer:

76.8

Step-by-step explanation:

So u basically do

f(11) = 0.01(2)^11 = 20.48

f(15) = 0.01(2)^15 = 327.68

The average rate of change will be uh 76.8

(327.68-20.48) /1 5-11 = 307.2/4

= 76.8

Answer:

x = 20

p = 144

y = 144

Step-by-step explanation:

Vertically opposite angles are equal.

2x - 4 = 96 - 3x

2x + 3x -4 = 96

    5x - 4 = 96

         5x = 96+4

         5x = 100

           x = 100/5

           x = 20

2x - 4 = 2*20 - 4 = 80 - 4

         = 36

p + (2x - 4) = 180  {linear pair}

p + 36 = 180

        p = 180 - 36

        p = 144

y =  p        {vertically opposite angles}

y = 144

Answer:

Step-by-step explanation:

Given

Finding (fog)(x)

(fog)(x)  = f(g(x))

(fog)(x)  = f(x+9)

(fog)(x)  = 5(x+9)             ∵ substitute x as x+9 in the f(x)

(fog)(x)  = 5x+45

Finding (gof)(x)

(gof)(x) = g(f(x))

(gof)(x)  = g(5x)

(gof)(x)   = 5x+9                 ∵ substitute x as 5x in the g(x)

Finding (fog)(3)

(fog)(3) = f(g(3))

substitute x = 3 in the g(x)=x+9

g(x) = x+9

g(3) = 3+9

g(3) = 12

so

(fog)(3) = f(g(3)) = f(12)

now substitute x = 12 in  f(x) = 5x

f(x) = 5x

f(12) = 5(12)

f(12) = 60

Thus,

(fog)(3) = f(g(3)) = f(12) = 60

Answer:

11 3/5 containers

Equivalent to 11.6 containers

Step-by-step explanation:

Total pounds of potato salad = 14 1/2 pounds

Pounds in each container = 1 1/4 pounds

How many containers does she need?

Number of containers needed = Total pounds of potato salad / Pounds in each container

= 14 1/2 ÷ 1 1/4

= 29/2 ÷ 5/4

= 29/2 × 4/5

= (29×4) / (2×5)

= 116/10

= 11 6/10

= 11 3/5 containers

Equivalent to 11.6 containers

Step-by-step explanation:

Answer:

y = 2x - 4

Step-by-step explanation:

Can I ask which variable you are solving?

PS I will assume you need the formula y=mx+b

-2x + y = - 4

Here you would translate the m and x variables to the right side making them positive.

y = 2x - 4

Now the formula is in proper form

Hey :)

If you are solving for x, the answer is: x = y/2 + 2

-2x + y = -4

Subtract y from both sides

−2x = −4 − y

The equation is in standard form:

−2x = − y −4

Divide both sides by −2:

-2x/-2 = -y - 4/-2

Dividing by −2 undoes the multiplication by −2

x = -y -4/-2

Divide −4 −y by −2

x = y/2 + 2

However, if you are solving for y, the answer is: y = −4 + 2x

−2x + y = −4

Add 2x to both sides:

y = −4 + 2x

Answer:

[tex]3^{12}[/tex]

Step-by-step explanation:

[tex]([/tex][tex]3^{5}[/tex][tex])^{2}[/tex]

You multiply the exponents to get:

[tex]3^{10}[/tex]

Then you divide it by [tex]3^{-2}[/tex]

When dividing exponents, you subtract.

10 - - 2 = 12 so the exponent is 12.

That leaves us with:

[tex]3^{12}[/tex]
