Answer:

12) y = 2x + 8

13) ( -4, 3)

14) y + 3 = 1(x + 2) ; y = x - 1

Step-by-step explanation:

12) ( -2, 4) and (1, 10)

m=(y2-y1)/(x2-x1)

m= (10-4)/(1+2)

m=6/3

m = 2

y - y1 = m(x - x1)

y - 4 = 2(x + 2)

y - 4 = 2x + 4

y = 2x + 8

13)

y - y1 = m(x - x1)

y - 3 = 2(x +4)

( -4, 3)

14) ( -2, -3) and (4, 3)

m=(y2-y1)/(x2-x1)

m=(3+3)/(4+2)

m=6/6

m=1

y - y1 = m(x - x1)

y + 3 = 1(x + 2)

y + 3 = x + 2

y = x - 1

Write a percent porportion and solve each number the numbers are 22 is 44% of what number?

Irina-Kira [14]

Answer:

The number is 50.

Step-by-step explanation:

If we express the percentage x% in the form of ratio then it can be written as $\frac{x}{100}$ .

Now, it is asked which number if we make 44 % will give 22.

Let the number is given by x.

Then expressing the % as ratio we can write $\frac{22}{x} = \frac{44}{100}$

⇒ $x=\frac{22 \times 100}{44} = 50$ ( Answer )

What is the net price if a purchase would have come to 1500 at the regular price but the 3% discount applied to this purchase

Julli [10]

Answer:

The net price of the product is $1445.

Solution:

Given, regular price of a product is $1500 and it has a discount at the rate of 3%

We have to find the final price of the product.

We know that, final product of price = regular price – discount price

Final price of product = 1500 – 3% of 1500

Final price of product $= 1500-\frac{3}{100} \times 1500$

= 1500 – 3 $\times$ 15 = 1500 – 45

Final price = 1455

Hence, the net price of the product is $1445.
