Answer 1

Answer: x + y = 3
- x - x
y = -x + 3

y - y₁ = m(x - x₁)
y - (-1) = -1[x - (-1)]
y + 1 = -1(x + 1)
y + 1 = -1(x) - 1(1)
y + 1 = -x - 1
- 1 - 1
y = -x - 2

The answer is B.

One point on a line is given the coordinate 5.3. A second point on the line has a coordinate of 8.7.The distance between these points is __________ units.

Answers

Answer: The distance between these points is 5 units.

Step-by-step explanation:

We know that by Distance formula , the distance between two points (a,b) and (c,d) is given by :-

$D=√((d-b)^2+(c-a)^2)$

The given points = (5,3) and (8,7)

The distance between theses points will be :

$D=√((7-3)^2+(8-5)^2)\n\n\Rightarrow\ D=√((4)^2+(3)^2)\n\n\Rightarrow\ D=√(16+9)\n\n\Rightarrow\ D=√(25)=\pm5$

Since , Distance is always positive , it means the distance between the given points is 5 units.

Answer:

3.2

Step-by-step explanation:

The distance formula on a number line is

d= x2-x1

d= 8.7-5.3 =3.2

Two cars leave Denver at the same time and travel in opposite directions. One car travels 10 mi/h faster than the other car. The cars are 500 mi apart in 5 h. How fast is each car traveling?

Answers

The speed of one car is 'S'. The speed of the other car is (S + 10).

In 5 hours, the first car travels (5S) miles, and the other car travels 5(S + 10) miles.

Since they're going in opposite directions, the distance between them at any time
is the sum of the distance that each one has traveled.

500 = (5S) + 5(S + 10)

500 = 5S + 5S + 50

500 = 10S + 50

Subtract 50 from each side:

450 = 10S

Divide each side by 10

S = 45

S + 10 = 55

Let one car travel at x mph

The other car travels at x+10 mph

Their combined speed is 2x+10 mph.

Distance = 500

time = 500 /2x+10 =5

10x+50=500

10x= 450

x=45 speed of one car

The other car travels at 45+10 = 55 mph

Which of the following is not a disadvantage of using cash instead of credit?a.
Using cash will not help you improve your credit rating.
b.
Using cash can be awkward when making large purchases.
c.
Using cash generally requires trips to the bank or ATM to keep cash on hand.
d.
Using cash can make it easier to over-spend since you know exactly how much you have.

Answers

The correct answer is:

D) Using cash can make it easier to over-spend since you know exactly how much you have.

Explanation:

Knowing exactly how much you have on hand will actually help you avoid over-spending.

When using cash, you are aware of exactly how much money you have. With a credit card, this may not be the case; this makes it easier with a credit card to spend more money than you should for your budget. With cash it's easier to avoid this problem.

The statement that is not a disadvantage of using cash instead of credit card is: Option D.

What is a Credit Card?

A credit card can be described as a payment card issued to an account holder, which allows card owners charge the card owner even beyond the deposit the individual has in their account.

The individual's account accrues a balance which the individual must pay in each month.

Using a credit card can be of disadvantage to an individual, because you may spend more than what you intend to spend.

Therefore, the statement that is not a disadvantage of using cash instead of credit card is: Option D.
