Write the equation of a line in point-slope form thatſgoes through the coordinate
(4, -3) and has a slope of 7. *

Answer:

y+2 = -3(x-2)

Step-by-step explanation:

Point slope form of an equation is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y - -2 = -3( x-2)

y+2 = -3(x-2)

Answer:

Y=-3x+4

Step-by-step explanation:

Please graphing and all I did was input the coordinates into the Y=mx+b form, got the b and filled in everything else. Hope this helps!

Answer:

D x>-3

Step-by-step explanation:

3(-x+2) < 15

-3x + 6< 15 (Subtract 6 from both sides)

-3x < 9 (Divide 3 on both sides)

x>-3 (Flip the inequality because the variable was negative)

Answer:

3/15 or 1/5 or 20%

Step-by-step explanation:

3+12=15 which is the total number of vases. 3 out of 15 vases were chipped so the probability that the next vase will be chipped is 3/15 or 1/5 or 20%.

Hi there!

The correct answer is: 408r in

Step-by-step explanation:

The formula for the volume of the cone is: V = [tex]\frac{1}{3}[/tex]π[tex]r^{2} h[/tex]

where h stands for height, in this case it's y=25

r stands for radius, in this case it's 7 in

when it says leave in terms of "r" it simply means don't multiply the π in

Answer:

2x(3y-4x)

Step-by-step explanation:

6xy - 8x^2

Factor out the greatest common factor of 2x

2x*3y  -2x*4x

2x(3y-4x)

Answer:

Equation of a circle:

radius = the sq. rt of (x - h)^2 + (y - k)^2

Plug in the values for the center of a circle and the radius:

15 = the sq. rt of (x + 9)^2 + (y + 4)^2

(x + 9)^2 + (y + 4)^2 = 225

The answer is A or the first one.

The answer would be B.

Answer:

p = -2

Step-by-step explanation:

(2p -1)/5 = (p-1)/3

Using cross products

(2p-1) *3 = (p-1)*5

Distribute

6p-3 = 5p -5

Subtract 5p from each side

6p-5p -3 = 5p-5p -5

p -3 = -5

Let's solve now

[tex] - \frac{8}{13} \times - \frac{26}{3} \\ = \frac{208}{39} \\ = \frac{16}{3} = 5 \frac{1}{3} [/tex]

Answer:

So we can first use the distance formula which is for 2 dimensional but seen as we're in 1 dimensions we dont have to use it. So we can just get the distance between them using a formula I made -

|a-d| = distance

So if we use that formula we can get that -7-(-2) = -7+2 = -5. Then take the absolute value which is 5.

Therefore the answer is

I've had this question on a test

Answer:

y = 2x - 6

Step-by-step explanation:

Slope-intercept form is  y = mx + b, where m is the slope and b is the y-intercept.

The y-intercept is already given and is -6.

By c intercept, I am assuming you meant x-intercept.  With an x-intercept of 3, the point is (3,0).  With a y-intercept of -6, the point is (0,-6).

Use the two points to find the slope using the following equation.

[tex]m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }[/tex]

Plug the points into their respective positions and solve.

[tex]m=\frac{-6-0}{0-3}\\ m=\frac{-6}{-3} \\m=2[/tex]

The slope is 2.

Your equation is  y = 2x - 6.

Answer:

a. 1. Trapezoid

2. Rectangle

b. Trapezoid

c.  Isosceles trapezoid

d. 6 feet

e. 65°

f. 115°

Step-by-step explanation:

a. The observed quadrilaterals are;

1. Trapezoid

2. Rectangle

b. Trapezoid

c.  Isosceles trapezoid

d. Whereby we have an isosceles trapezoid, the leg lengths are equal. therefore since one of the leg lengths = 6 feet, the other opposite leg on the side of the roof = 6 feet

e. The base angles of an isosceles triangle are equal, therefore, the other base angle is equal to the labelled base angle or 65°

f. The sum of the opposite angles in an isosceles trapezoid = 180°

∴ 65° + Opposite angle = 180°

Opposite angle = 180° -  65° = 115°.

Answer:

difference of cost between two company = 12  - 0.12 x

Step-by-step explanation:

For company ABC

start up fee = $12

cost of one minute call = $0.08

if x minute call are done then cost of x call =  0.08*x =  0.08x

total cost incurred in company ABC= startup fee+ cost of x minute call = 12+0.08X

___________________________________________________

For company WYZ

start up fee = 0

cost of one minute call = $0.20

if x minute call are done then cost of x call =  0.20*x =  0.20x

total cost incurred in company WYZ plan = startup fee+ cost of x minute call = 0+0.20x = 0.20x

______________________________________________

difference of cost between two company = 12+0.08x - 0.20x

difference of cost between two company = 12  - 0.12x (Answer)

Answer:

20

Step-by-step explanation:

To find area using coordinates, you would take the y-value of the first coordinate and the x-value of the second coordinate and multiply them. Then, take the x-value of the first coordinate and multiply it with the second y-coordinate. Take the second number and subtract it from the first number. for multiple coordinates, you would multiply the first and the second, the second and the third, and so on. Once you reach the last coordinate, just multiply it by the first again. then, take all of the numbers, from multiplying your coordinates and add them together and divide them by 2 to find your area.

We would start with coordinate (8,1) here because it's letter variable is W, which is first of the others alphabetically.

(8,1) (1,1)

1 x 1 = 1

8 x 1 = 8

1 - 8 = -7

next coordinate:

(1,1) (2,5)

1 x 2 = 2

1 x 5 = 5

2 - 5 = -3

next:

(2,5) (5,5)

5 x 5 = 25

2 x 5 = 10

25 - 10 = 15

next:

(5,5) (8,1)

5 x 5 = 40

5 x 1 = 5

40 - 5 = 35

-7 - 3 + 15 + 35 = 40

40/2 = 20
