Which equation describes the same line as y – 3 = –1(x + 5)?A. y = –1x – 5
B. y = –1x – 2
C. y = –1x – 1
D. y = –1x + 8

Answers

Answer:

Option B is correct.

$y= -1x-2$

Step-by-step explanation:

The distributive property says that:

$a \cdot (b+c) = a\cdot b+ a\cdot c$

Given the equation of line:

$y-3 = -1(x+5)$

Apply the distributive property we have;

$y-3 = -1x-5$

Add 3 to both sides we have;

$y-3+3= -1x-5+3$

Simplify:

$y= -1x-2$

Therefore, an equation describes the same line as y – 3 = –1(x + 5) is, $y= -1x-2$

y – 3 = –1(x + 5)

y - 3 = -x - 5

y = -x - 5 + 3

y = -x - 2

answer is B. y = –1x – 2

The price of a pair of shoes is $28. The sales tax rate is 2.39 percent. What is the total amount you would pay if you bought these shoes?

Answers

Answer:

Total amount pay for the shoes is $28.67 .

Step-by-step explanation:

As given

The price of a pair of shoes is $28.

The sales tax rate is 2.39 percent.

2.39% is written in the decimal form .

$= (2.39)/(100)$

= 0.0239

Sales tax price = 0.0239 × Price of pair of shoes

= 0.0239 × 28

= $ 0.6692

= $0.67 (Approx)

Total shoes price = Price of pair of shoes + Sales tax price

Put all the values in the above

Total shoes price = $28 + $0.67

= $ 28.67

= $28.67

Therefore the total amount pay for the shoes is $28.67 .

$28.67 Multiply 28 x 0.0239 = 0.6692 round up to .67 and then add that answer to 28 and you get the answer of 28 dollars and 67 cents

A CARPENTER BOUGHT A PEICE OF WOOD THAT WAS 371.952 CENTIMETERS LONG . TTHEN HE SAWED 0.68 CENTIMETERS LONG OFF THE END. HOW LONG IS THE PEICE OF WOOD NOW

Answers

Answer: the piece of wood is now 371.272 centimeters long. also please stop yelling.

Step-by-step explanation: To find the length of the piece of wood after 0.68 centimeters are sawed off, you need to subtract 0.68 from the original length of 371.952 centimeters.

371.952 - 0.68 = 371.272 centimeters

1. what is the GCF of the terms of 8c^3+12c^2+10c? A.2
B.4
C.2c
D.4c

2. How can the polynomial 6d^4+9d^3-12d^2 be factored l?

Answers

Answer:

1. C. 2c

2. $3d^2(2d^2+3d-4)$

Step-by-step explanation:

A. We have been given an expression and we are asked to find the GCF of our given expression.

$8c^3+12c^2+10c$

Let us find factors of each of our given terms.

Factors of $c^3$ are $c*c*c$ ,

Factors of $c^2$ are $c*c$ ,

We can see that c is the greatest common factor of $c^3$ , $c^2$ and $c$ .

Factors of 8 are: 1, 2, 4, 8.

Factors of 12 are: 1, 2, 3, 4, 6, 12.

Factors of 10 are: 1, 2, 5, 10.

The greatest common factor of 8,12 and 10 is 2.

So let us factor out 2c from our expression.

$2c(4c^2+6c+5)$

Therefore, the greatest common factor of our given expression is 2c and option C is the correct choice.

2. We have been given a polynomial and we are asked to factor our given polynomial.

$6d^4+9d^3-12d^2$

We will pull out the greatest common factor of the terms of our given polynomial.

We can see that GCF of $d^4$ , $d^3$ and $d^2$ is $d^2$ .

The GCF of 6, 9 and 12 is 3.

So let us factor out $3d^2$ from our polynomial.

$3d^2(2d^2+3d-4)$

Therefore, the factored form of our given polynomial is $3d^2(2d^2+3d-4)$ .

If you pay attention 2 goes into 8, 10, & 12 and it looks like they all have one C. So what do you think it is lol?(:

Are the angles with the given measures complementary, supplementary, or neither? m∠J = 63° and m∠K = 27°

Answers

They're complementary.
Complementary angles are a pair of two angles that add up to a sum of 90 degrees
Supplementary angles add up to 180 degrees
63 + 27 = 90

well if the total is 90 so its complementary...
