Mathematics
1 answer:

Answer:

(x1,y1)=(−2,2)

(x2,y2)=(0,−2)

Use the slope formula:

m= y2−y1 /x2−x1

= −2−2 /0−−2

= −4 /2

=−2

Answer:

m=−2 This is the slope

So,the slope intercept form for 2 points is y-y1=m(x-x1)   m=slope  

y-y1=m(x=x1)

y-2=-2(x-(-2)     ( - and - is +) So,the final equation is:

y-2=-2(x+2)

I hope this help you :)

Hello from MrBillDoesMath!

Answer:

5, 10, 0

Discussion:

Let "f" be the first number. Then the questions tells us that

f + 2f  + (f-5) = 15           =>

f + 2f + f - 5 = 15            => add 5 to both sides

4f = 5+ 15 = 20              => divide both sides by 4

f = 20/4 = 5

The numbers as

f:        5

2f:     10

(f-5):  0

Thank you,

MrB

PLEASE PLEASEE ANSWER THE QUESTION IN THE PICTURE BELOW
KatRina [158]

Answer: Choice C

Vertex = (5, -2)

===============================================

Explanation:

Vertex form is y = a(x-h)^2 + k where the vertex itself is located at (h,k)

As the name implies, we can very quickly pull out the coordinates of the vertex without doing much math at all.

In the case of choice C, we have y=  \frac{1}{2}(x-5)^2 - 2 which is the same as y = \frac{1}{2}(x-5)^2 + (-2) and we can see that h = 5 and k = -2. Therefore, the vertex is located at (h,k) = (5, -2)

Question: The hypotenuse of a right triangle has a length of 14 units and a side that is 9 units long. Which equation can be use
kramer

Answer:

The hypotenuse is the longest side in a triangle.

a^2=b^2+c^2.

14^2=9^2+c^2.

c^2=196-81.

c^2=115.

c=√115.

c=10.72~11cm
