Write an equation of the line that passes through each pair of points.
(-3,9), (-3,-5)
** Will mark brainliest, please show work!**

Answers

Answer 1

Answer:

y = 0x - 5 or just y = -5

Step-by-step explanation:

use the slope intercept equation

y2 - y1

x2 - x1

- 5 - 9 = 14

-3 + 3 = 0

14 / 0 = 0

so the slope is undefined

take one of the points (let's use -3, -5) and plug that in the slope intercept form (y = mx+b)

so -5 = 0(-3)+b

0 • 3 = 0 so the b (or y intercept) equals -5

so the equation is y = -5

A basketball team scored a total of 1470 points over the course of its 21-game season. 470 of the points were from 1-point baskets. The remaining points were either 2-point or3-point baskets.
There were 440 2-point or 3-point
baskets scored. How many of those 440 baskets were 3-point baskets?

Answers

To solve this you'll want to set up a system of equations.

Since there were 1470 points scored total, and 470 of them were from 1 point baskets, that means 1470-470 = 1000 points were scored by 2 and 3 point baskets. Assuming x = the number of 2 point baskets scored and y = the number of 3 point baskets scored, that gives us an equation of 2x + 3y = 1000.

We also know that there were a total of 440 2 or 3 point baskets scored. Using x and y as defined before, we get an equation of x + y = 440.

To solve this, we can use substitution. Let's solve for x in terms of y for the second equation.

So x + y = 440. If we subtract y from both sides, we get x = 440 - y. Now we substitute 440 - y for x in the first equation.

2*(440-y) + 3y = 1000. Now we simply solve the equation.
880 - 2y + 3y = 1000.
880 + y = 1000.
y = 120.

So 120 of the baskets scored were 3 point baskets.

If we want to solve for x, we can substitute in the known value of y to the first equation
x + 120 = 440.
x = 320.

So 320 of the baskets scored were 2 point baskets.

Twice a number is 26?

Answers

Answer:

13x2 is 26

Step-by-step explanation:

Answer: The answer is 13.

Step-by-step explanation: This is because if you set up the equation

2x = 26 then you divide by 2 on each side, this would leave you with x = 13 which is the answer.

State the equation of the line described.
A line passes through the point (-2,8) and is perpendicular to the line y = -3x + 3.


thank you guys!

Answers

Answer:

y = mx + b

Since it is perpendicular to the given line, its slope is the negative reciprocal of the slope of the given line.

Slope of given line:

m0 = -a/b = -(-3) / (1) = 3

Slope of perpendicular line:

m = -1/3

y = (-1/3)x + b

Use the given point to find b.

2 = (-1/3)(3) + b

2 = -1 + b

b = 3

y = (-1/3)x + 3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Perpendicular lines have their slope negative reciprocal

y= -3x +3 has the slope -3

y = (1/3)x +b is the line that is ⊥ so it has the slope (1/3)

The line passes trough the point (x=-2, y=8) so substitute the x and y to find b

8 = (1/3)(-2) +b, multiply (1/3)(-2) = -2/3 and add 2/3 on both sides

8+(2/3) = b, find the common denominator and add the fractions

[(3*8)+2 ]/3 =b

(26/3)  = b

The equation of the line described is y= (1/3)x +(26/3)

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $28 monthly fee and charges an additional
50.08 for each minute of calls. The second plan has a $19 monthly fee and charges an additional $0.13 for each minute of calls. For how many minutes of calls
w the costs of the two plans be equal?

Answers

Answer:

180 minutes

Step-by-step explanation:

Let x be the number of minutes of calls.

The first plan has a $28 monthly fee and charges an additional $0.08 for each minute of calls:

p(f) = 0.08x + 28

The second plan has a $19 monthly fee and charges an additional $0.13 for each minute of calls:

p(s) = 0.13x + 19

When p(f) = p(s) we get the following equation for x:

0.08x + 28 = 0.13x + 190.13x - 0.08x = 28 - 190.05x = 9x = 9/0.05x = 180

Antonia bought a set of dishes, a towel, and a candle at a housewares store. The set of dishes cost $35.02, the towel cost $21.43, and the candle cost $9.59 before any coupons or discounts.

She used a $0.50-off coupon on the candle, a $2.75-off coupon on the towel, and the set of dishes was on sale for 10% off the regular price. Which of the following best describes the amounts that Antonia saved?

Answers

Answer:

Antonia saved $5.39

Step-by-step explanation:

Candle:

$9.59 - $0.50 (coupon) = $9.09

Towel:

$21.43 - $2.75 (coupon) = $18.68

Dishes:

$21.43 x 10% = 2.143

$21.43 - $2.143 = $19.287, rounded to the nearest cent and it’s $19.29.

Calculate the amount of money saved by adding 0.50 + 2.75 + 2.143, which is 5.393. Round to the nearest cent and it will be $5.39.

Answers

Answer:

P=145.8m

Step-by-step explanation:

Answer: The perimeter is 145.8 square meters

Step-by-step explanation:

Area=513.5 square meters

513.5=l (length) times w (width)

513.5= 7.9 times w

513.5= 7.9w

(DIVIDE 513.5 AND 7.9 BY 7.9)

65= w

Perimeter= 2l + 2w

Perimeter=2(7.9) + 2(65)

Perimeter=15.8 + 130

Perimeter=145.8 square meters
