2 - x = - 7

Adding x at both sides of the equal signe, we get:

2 - x + x = - 7 + x

2 = -7 + x

Adding 7 at both sides:

2 + 7 = -7 + x + 7

Step-by-step explanation:

The cost of Brandon's taxi ride is $ 4.8.

A taxi ride in a large city costs $3.50 plus $6 for each mile traveled .The 3 mile cab ride includes a basic charge as well as the cost for the distance covered.If Brandon traveled 7.5 miles by taxi, how much was the cost, C, of his taxi.

For a 6 mile trip, the cost is $4.80 which means that :

The cost of 3 miles is $4.80−$3.00=$1.80

Therefore the cost for 1 mile is $1.80÷3=$0.60

The basic fee for hiring the cab is $3.00−$1.80=$1.20

So the total cost, c for a trip of d miles will be shown below:

c=0.6d+1.2

Check:

If d=3

c=0.6(3)+1.2=3

If d=6

c=0.6(6)+1.2= 4.8

If Vladimir is looking to retire in 10 years and he has planned to put $25,000 into an investment from today itself, that earns interest at a fixed amount per year, considering the rate of interest to be (R%) per annum, the domain and range for a function modeling the total amount of the investment, including interest are as follows:

Domain [X = {0 ≤ years ≤ 10}]

Range (total amount), [Y = {$25,000 ≤ Y ≤ 25,000( 1 + 10R)}]

As per the question statement, Vladimir is looking to retire in 10 years and he has planned to put $25,000 into an investment from today itself, that earns interest at a fixed amount per year, and since there is no information about the rate of interest of that investment, we are considering the rate of interest to be (R%) per annum.

We are required to determine the domain and range for a function modeling the total amount of the investment, including interest using the question statement mentioned data and our assumptions.

Since the starting principal amount, say P is $25,000, given,

Time of investment, say T is 10 years, also given,

And considering the interest rate per year to be R (%),

Then after 10 years, the total amount Vladimir has is [25000( 1 + xR)].

Where, the Domain (No. of years ) is [X = {0 ≤ years ≤ 10}]

And Range (total amount), [Y = {$25,000 ≤ Y ≤ 25,000( 1 + 10R)}]

The thing that she can do to increase the savings is A. Deposit money into her savings account each month.

Your information is incomplete and the complete question is written below. Savings accounts offer interest based on the balance. Therefore, you can boost the interest you receive on a savings account by making a deposit each month. By doing so, you will increase the account's total balance and, consequently, the interest rate.

The alternate selections are incorrect since doing so will result in a decrease in the amount of money in the savings account and a reduced rate of interest. Instead, use the money to open a checking account.

Step-by-step explanation:

=====================================================

Explanation:

5624 is close to 5600

72 is close to 70

Therefore, 5624 ÷ 72 is close to 5600 ÷ 70 = 80

Think of it like saying 56 ÷ 7 = 8 but then we add the zeros onto each to get what is shown above.

--------

Use your calculator to find that

5624 ÷ 72 = 78.111 approximately

which isn't too far from the estimate value of 80. Our estimate is an over-estimate.

Answer: 80

Step-by-step explanation:

First change the equation to the nearest tenth,
5620 divided by 70

Now, break up the 70 into ( 10 * 7 )

So first do 5620 divided by 10

5620 divided by 10 = 562

Now if we round to the nearest tenth again we get 560

Now we can divide 560 by 7

Which comes out to 80

So first of all we have to solve this equation:

We can perform the operation 94+91=185 so we get:

And we can substract 185 from both sides of the equation:

Then the answer to part a is 215.

Now that we have the number of seats on the stage level we can find the max amount of money the theater can bring in. This will be given by the total number of seats in the stage level multiplied by the cost per ticket for these seats plus the total number of seats in balconies (185) multiplied by the cost per ticket for these seats. Then we get:

Then the max amount of money the theater can bring in for a show and answer to part b is $11075.

It's answer is option(C) i.e, 4/15

The average rate of function f  over the interval a≤x≤b is given by ,

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

It is the average amount by which the function changed per unit throughout that time period.

In this question the equation is given,

g(x) = log2 (x+6)-3

Solve this eq. by putting the values [-5, 10],

let, interval [-5, 10] = [a, b]

Then solve for g(a) and g(b), we know g(a) = g(-5),

g(-5) = log₂(-5+6) - 3

       = log₂1 - 3

       = 0 - 3

g(-5) = -3

Now, for g(b) = g(10)

g(10) = log₂(10+ 6) - 3

        = log₂16 - 3

        = 4 - 3

g(10) = 1

Now put these values in average rate formula,

Average rate = (g(b) - g(a)) / (b - a)

                      = (1 - (-3)) / (10 - (-5))

                      = (1 + 3) / (10 + 5)

                      = 4 / 15

Therefore, the average rate is 4/15 i.e, option(C)

Non shadow part (white one) seems to be 1/4 of a circumference

So we need to find area of square minus area of 1/4 of the circumference

Square area = L^2 = 6^2 = 36

Circumference Area = (πr^2)/4 = (π*6^2)/4 = 28.27

Area of the shaded portion = 36 - 28.27 = 7.72

o=day 1. t=day 2. th=day 3

o+t+th=36

o+4=th

64o+62t+58th=2196

(o+t+th=36)*58

58o+58t+58th=2088

64o+62t+58th=2196

-(58o+58t+58th)=2088

6o+4t=108

o+t+th=36

o+t+o+4=36 ==> th=o+4

2o+t+4=36

2o+t=32

(2o+t=32)*3

6o+4t=108

t=108-96

t=12

2o+12=32 ==> 2o+t=32

2o=20

o=10

o+4=th
