You rent an apartment that costs $800 per month during the first year, but the rent is set to go up $170 per year. What would be the monthly rent during the 8th year of living in the apartment?

Answers

The monthly rent during the 8th year of living in the apartment will be $2160.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

You rent an apartment that costs $800 per month during the first year, but the rent is set to go up by $170 per year.

Then the monthly rent during the 8th year of living in the apartment will be

Let y be the monthly rent and x be the number of years.

Then we have

y = 170x + 800

The rent after 8 years, then the rent will be

y = 170 × 8 + 800

y = 1360 + 800

y = $ 2160

Thus. the monthly rent during the 8th year of living in the apartment will be $ 2160.

Answer:

(f o g)(4)=27

Step-by-step explanation:

(f o g)(4)=2x+5

f(g(4))=2x+5

f(4²-2(4)+3)=2x+5

f(16-8+3)=2x+5

f(8+3)=2x+5

f(11)=2x+5

f(11)=2(11)+5

f(11)=22+5

f(11)=27

Therefore, (f o g)(4)=27

please help me with this slope problem! :) (brainliest)

Answers

Answer:

Plot these points

(1,935)

(2,870)

(3,805)

(4,740)

(5,675)

Slope= -65

y intercept = 1000

and what it's saying is that we travel at a speed of 65 units an hour and we start 1000 miles away

Step-by-step explanation:

Just graph these points which you can get by plugging in the numbers

1000-65= 935

(1,935)

1000-65*2=870

(2,870)

1000-65*3= 805

(3,805)

1000-65*4=740

(4,740)

1000-65*5= 675

(5,675)

B:

y= mx+b where m is the slope and B is the y intercept

we can re write the equation as follows

-65x+1000

It's pretty clear that -65 is the slope and 1000 is the y intercept

what is the inverse of f(x)=2-2x

Answers

In the usual sense, it has no inverse function. Since it is not an injection (f(0)=f(2)=0), an inverse function would have to map 0 both to 0 and 2, and that’s impossible.

However, if you restrict the domain to [1,+oo> (to make it injective), and the codomain to [-1,+oo> (to make it surjective), then it has an inverse function, given by g(y)=1+sqrt(y+1).

Mr. And Mrs. Jenkins wanted to make a down payment of $25,000 on a house. If the house costs $125,000, what percent is this?

Answers

Answer:

20%

Step-by-step explanation:

Mr. And Mrs. Jenkins wanted to make a down payment of $25,000 on a house. If the house costs $125,000, what percent is this?

The Percentage of the down payment is given as:

Down payment/Cost of the house × 100

Down payment = $25,000

Cost of the house = $125,000

$25,000/$125,000 × 100

= 20%

The percentage is 20%

for the pairs below put each question in slope intercept form and whether the graphs of the line will be identical, parallel, or intersecting, Also determine how many solutions the system of equations will have​

Answers

3: rearrange the 2nd equation so y is isolated, add 3x to both sides
Both equations are now y = 3x + 2. So they are identical, and therefore have infinite solutions since solution means how many times do these lines meet/overlap.

4: rewrite left-right and the equations are now:
y = -x
y = -x -2
Same slope but different intercept (b value), so they are parallel and NEVER meet (NO SOLUTIONS)

5. Rearrange:
y = -x + 4
y = x + 4

So they have different SLOPES in this example (m value). This means they are not parallel or identical, so they can only cross once (one solution)

6: rearrange both
y = 3x - 1
y = 3x + 1
Same slope (m=3), different intercepts (b= 1 and -1). Same slope means parallel, different b means different intercepts so they are NOT identical. Since parallel lines can not cross, there are no solutions

7: y = 2x + 4
y = 2x - 4
Same slope (m=2), different b values (y-intercepts are 4 and -4), so parallel but not identical, no solution

You roll a spinner that is numbered 1-4. What is the probability of landing on a number less than 3 and then landing on a 4? (determine the answer and explain your process for doing so)

Answers

Answer:

The probability is 1/4

Step-by-step explanation:

So there's 4 possible outcomes. So if you roll the spinner and you can only get one outcome. So it'll be 1/4.

Answer:

P(<3, then 4) = 1/2 x 1/4 = 1/8

Step-by-step explanation:

probability of a number less than 3 would mean landing on a 1 or 2, which has a prob. of 1/2

probability of landing on the number 4 is 1/4

multiply the probabilities

Answers

p and q are the numbers of pillows and quilts, respectively.
4p+5q = 57
9p+5q = 72

Subtract the second equation from the first equation.

4p+5q = 57
-9p-5q = -72
——————
-5p = -15

p = 3

4(3)+5q = 57
5q = 57-12 = 45
q = 9

A pillow costs $3. A quilt costs $9.

  y = y^2/2

  y^2/2 -y = 0

  y(y/2 -1) = 0 . . . . factor out y

Values of y that make these factors zero are ...

  y/2 -1 = 0   ⇒   y = 2

Then the segment lengths are ...

Frank invests $1,000 in simple interest investment account that pays 8% a year. After a number of years, he withdraws his balance of $2,200. Using the formula I = P r t, how many years was his money invested? Work backwards-but find the Interest first!

Answers

Answer:

15 years

Step-by-step explanation:

Given data

P=$1,000

R=8%

A= $2200

I= A-P

I=2200-1000

I=$1200

Applying the formula

I=PRT/100

1200=1000*8*T/100

cross multiply

1200*100= 8000T

120000= 8000T

divide both sides by 8000

T=120000/8000

T=15  years

Hence the time is 15 years

If Earth's total mass is 6 x 10^24 kg, what proportion of this is lost every year?

Answers

Step-by-step explanation:

This is well within the mass uncertainty of 0.01% (6×1020 kg), so the estimated value of Earth's mass is unaffected by this factor. Mass loss is due to atmospheric escape of gases. About 95,000 tons of hydrogen per year (3 kg/s) and 1,600 tons of helium per year are lost through atmospheric escape.

Point VV is located at (-5,3)(−5,3) on the coordinate plane. Point VV is reflected over the yy-axis to create point V'V ′ . Point V'V ′ is then reflected over the xx-axis to create point V''V ′′ . What ordered pair describes the location of V''?V ′′ ?

Answers

Given:

Point V is located at (-5,3) on the coordinate plane.

It is reflected over the y-axis to create point V'.

Point V' is then reflected over the x-axis to create point V''.

To find:

The location of point V''.

Solution:

We have,

Point V= (-5,3)

If point V reflected over the y-axis, then

[tex](x,y)\to (-x,y)[/tex]

[tex]V(-5,3)\to V'(5,3)[/tex]

If point V' reflected over the x-axis, then

[tex](x,y)\to (x,-y)[/tex]

[tex]V'(5,3)\to V''(5,-3)[/tex]

Therefore, the ordered pair (5,-3) describes the location of V''.

Walls were painted with resin or tar before being covered with the first of three layers of plaster. . . . A sketch of the projected work was then made on the plaster to serve as a guide for the various artisans. The outermost layer of plaster, in which the pieces, or tesserae, of the mosaic would be set, was spread on only enough area to contain a days work. Some of the tesseraesmall, carefully cut fragments of colored glass, marble, and semiprecious stoneswere pressed into the wet plaster so that they projected at a slight angle. The stones thereby better reflected light and imbued the finished mosaic with a shimmering life of its own.Empires Besieged: Time Frame A.D. 200600Which sentence of this passage best states the main idea?a.firstc.fifthb.thirdd.seventhPlease select the best answer from the choices providedABCD
