What are the factors of expression (y-3)(x+7)

1 answer:

4 0

That is easy!! :)
y=3 and x=-7

When you find the factors of something like this, you have to just get the letter alone.

For example: y-3. You have to first write it as y-3=0, then you add 3 from BOTH sides of the = so that you can make the -3 go away and y will be alone. So, it will look like this: y-3+3=0+3. Then, you solve it for y (which just means that you want y by itself on one side of the = ). So, -3+3=0, which means they disappear from that side; since 0+3=3, that's what that side turns into, so what you end up with is y=3

Same thing goes for the x+7 equation:
x+7=0
x+7-7=0-7
x=-7

Nathans drive to and from work each day is about 45 miles if he goes to work 226 days in a given year what is the minimal amount

enot [183]

Answer: The minimum amount that Nathan will pay including extra charges for exceeding mileage limit is $5,598.50¢

Step-by-step explanation:

Since Nathan went to work for 226 days, covering 45 miles daily to and from work with the car he leased from the leasing company, he therefore covered a total of:

45 × 226

= 10170 miles.

He covered a total of 10170 miles in that particular year.

If the mileage limit was 10,000 miles, then the additional miles that will attract extra charges will be derived by subtracting the mileage limit from the total miles covered within the given period =

10170 - 10,000

= 170 miles

If the extra mile charge on every mile that exceeds the mileage limit was set at $0.25 per mile, then the amount that Nathan will pay for only exceeding the mileage limit within the year =

0.25 × 170

= $42.50

Again, if leasing a car from the company attracts a monthly payment of $463, the amount that is expected of Nathan to pay for leasing the car from the company for the year is then:

$463 × 12 months

= $5,556

The minimum amount that Nathan will pay for the car in that particular year including charges for exceeding the mileage limit will then be:-

$5,556 + $42.5

= $5,598.50

What algebraic expression represents GK?

dsp73

Answer:

Part a) GK=(7x+1)

Part b) GH=5 units and JK=8 units

Step-by-step explanation:

Part a) what algebraic expression represents GK?

we know that

GK=GH+HJ+JK

step 1

Find GH

we have

GH=GJ-HJ

substitute the given values

GH=(2x+3)-x=x+3

step 2

Find JK

JK=HK-HJ

substitute the given values

JK=(6x-2)-x=5x-2

step 3

Find GK

GK=GH+HJ+JK

we have

GH=x+3

HJ=x

JK=5x-2

substitute

GK=(x+3)+x+(5x-2)

GK=(7x+1)

Part b) If GK=15, what are GH and JK?

we know that

GK=(7x+1)

For GK=15

substitute the value of GK and solve for x

15=(7x+1)

7x=15-1

7x=14

x=2

Find the value of GH

GH=x+3

substitute the value of x

GH=2+3=5 units

Find the value of JK

JK=5x-2

substitute the value of x

JK=5(2)-2=8 units

You get tired of the sand and head up to the amusement park. You can purchase 20 ride tickets for $14 or you can purchase 30 rid

Helga [31]

Answer:

The one with the better deal would be 30 ride tickets for $22.50 this is because you pay less money for more rides.

Step-by-step explanation:

First you divide 20 by 14. Doing this will give you the cost of a ride per ticket.

20/14 = 1.42

Then you do the same thing to 30 and 22.50.

30/22.50 = 1.30

Last you compare which deal has less money per ride.

1.42 > 1.30
