What I Want To Know Is.. Why Is That Possible?And, Why We Could Add The Two Inequalities Together Down

Answers

Answer 1

Answer: Explanation below.

Step-by-step explanation:  A good question, since working with inequalities  and using the same operations as with "=" equations is a bit uncomfortable.  I don't have a mathematical proof for this operation, but approach it with a "Why not?" attitude.  If 9>6 and 130 > 30, why wouldn't 139>36?  There is nothing in the add operation that should upset the basic inequality.  I suggest https://www.storyofmathematics.com/inequalities-math for more information.

The function y = 5.75 + 2.5(x - 2) can be used to determine cost in dollars to rent a house of x square feet. What is the rate of change of the cost in dollars with respect to the number of square feet?

Answers

The rate of change is given by the coefficient of x in the cost function. Hence, the rate of change of cost in the function is 2.5

Given the cost function :

y = 5.75 + 2.5(x - 2)

Expanding the function and expressing in slope intercept form:

y = 5.75 + 2.5x - 5

y = 2.5x + 2.75

Therefore, the slope of the function is 2.5 ; which ubsthe rate of change of the cost function.

how do I determine what a function is for a line graph

Answers

Answer: Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

Michael wants to save $46,000.00 for a down payment on a home. How much will he need to invest in an account with 6.1% APR, compounding daily, in order to reach his goal in 7 years? Round the answer to the nearest cent

Answers

Step-by-step explanation:

Simple Interest

Discussing interest starts with the principal, or amount your account starts with. This could be a starting investment, or the starting amount of a loan. Interest, in its most simple form, is calculated as a percent of the principal. For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5. The total amount you would repay would be $105, the original principal plus the interest.

EXAMPLES

A friend asks to borrow $300 and agrees to repay it in 30 days with 3% interest. How much interest will you earn?

Show Solution

The following video works through this example in detail.

One-time simple interest is only common for extremely short-term loans. For longer term loans, it is common for interest to be paid on a daily, monthly, quarterly, or annual basis. In that case, interest would be earned regularly.

For example, bonds are essentially a loan made to the bond issuer (a company or government) by you, the bond holder. In return for the loan, the issuer agrees to pay interest, often annually. Bonds have a maturity date, at which time the issuer pays back the original bond value.

EXERCISES

Suppose your city is building a new park, and issues bonds to raise the money to build it. You obtain a $1,000 bond that pays 5% interest annually that matures in 5 years. How much interest will you earn?

The Blazers hockey team has won 5 of its first 12 games. No game was tied. The Rockets’ record is 5 wins and 3 losses. Which team has the better record?
help please

Answers

Answer:

The Rockets' team has the better record.

Step-by-step explanation:

The Blazers hockey team has played 12 games but they won only 7 out of the 12 games, so that means that they loss the other 5 games. So that makes the Blazers record 7 wins and 5 losses.

The Rockets' team has played 8 games but they won only 5 out of the 8 games, so that means that they loss the other 3 games. So that makes the Rockets' record 5 wins and 3 losses.

So, the Rockets' team has the better record because they loss less games than the Blazers team did.

Find the X intercept and the Y intercept for 2x-6y=12

Answers

Answer:

x: (6,0)

y: (0,-2)

Step-by-step explanation:

To find the x-intercept, substitute in  0  for  y  and solve for  x . To find the y intercept, substitute in  0  for  x  and solve for  y .

Ex -

X : 2x -6(0)=12

2x=12

2 cancels out with 2

12/2 = 6

Y: 2(0 )- 6y =12

-6y=12

negative 6 times negative 6 cancels

12/-6 = -2

Answer:

See Below

Step-by-step explanation:

Given: 2x-6y=12

Plug 0 in the equation for y:

y is zero

2x-6(0)=12

2x=12

The x-intercept:  (6,0)

Plug 0 in the equation for x:

x is zero

2(0)-6y=12

−6y=12

The y-intercept:  (0,−2)

Answers

Step-by-step explanation:

I can't see picture very well but as I see first angle is

-4x+5 and second is -13x+39 ( if it isn't, correct me)

sum of this angles is 180° because they are inner angles

(-4x+5) + (-13x+39) = 180

-4x+5 -13x+39=180

-17x+44=180

-17x = 180-44

-17x= 136

x= -8

angle -4x+5 will be:

-4*-8 + 5= 32+5= 37°

Answers

Answer:

x = 9

Step-by-step explanation:

Vertical angles are congruent ( equal to each other )

So if ∠A and ∠B are vertical angles than they are congruent ( so ∠A = ∠B )

If ∠A = 2x + 1 and ∠B = x + 10

Then 2x + 1 must equal x + 10

( note that we've just created an equation that we can use to solve for x )

We now solve for x using the equation we just created

2x + 1 = x + 10

Subtract x from both sides

x + 1 = 10

subtract 1 from both sides

x = 9

1.45 x 10^2

Step-by-step explanation:

In scientific notation, you get the number down to 1 digit before the decimal place and all the rest after it, then multiply by 10 raised to a power in order to get it back to the original. An easy way to do it is to count the number of times you moved the decimal and remember which direction you did it. The number is the power (in this case 2) and the direction tells you if it's positive or negative (in this case it was to the left, so it's positive two.)

In simpler terms, slide the decimal to the right two places and make it 1.45, then multiply it by 10^2 (which is 100) to make it equal to 145. This leaves you with 1.45 x 10^2.

Answer: 1.45 x 10^2


when making a whole number a decimal, the decimal is at the end of the number so you move it to make it have just one whole number. Then the times you moved the decimal forward is how many exponents you write in top

You have at most $20 to spend at an arcade. Arcade games cost $0.75 each, and snacks cost $2.25 each. Write an inequality that represents the numbers of games (x )you can play and snacks( y) you can buy.
The inequality is ??

Answers

Answer:

y ≤ -1/3x+80/9

Step-by-step explanation:

(1). 0.75(x)+2.25(y) ≤ 20

0.75 - Number of arcade games (X).

2.25 - Number of snacks (Y).

20 - The total.

(2). 0.75x+2.25y≤20

(After multiplying the x's and y's together, with the numbers).  

(3). 0.75x (-0.75x) + 2.25y ≤ 20 (-0.75x)

(Subtract -0.75x to each side, which allows the equation to get closer to the answer).

(4). 2.25y       -0.75x + 20

   ————   =   ————

    2.25            2.25

(Divide by 2.25 to each side).

(5). y ≤ -1/3x + 80/9
