Help Please!!!What is the slope of the line passing through the points (-1, 7) and (3, 4)?

A) 4/3
B) 3/4 (wrong)
C) -3/4
D) -4 (Wrong)

Answers

Answer:

The answer is option C

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

We have

[tex]m = \frac{4 - 7}{3 - - 1} = \frac{ - 3}{3 + 1} = - \frac{3}{4} \\ [/tex]

We have the final answer as

[tex] - \frac{3}{4} \\ [/tex]

Answers

The answer is C.) x=15

The equation that you provided is - x - 6 = -26

To solve it, we need to isolate x, so we add 6 to both sides and we get

Now, we have to isolate x by doing the reciprocal of  which is  

So we multiply both sides by  to cancel it out and we are left with

Step-by-step explanation:

Step-by-step explanation:

draw 3 boxes.

put 6 on the side of the one on the left and then put 3 over the first two boxes and then put one over the last box. then on the side of the last box draw three tiny ones.

i'll try and draw it

    3    3    1

6 (18) (18) (6) then draw three tiny boxes.

you do this because 6 times 3 is 18 and if you do that twice its 36. then you do 6 times 1 which gives you 6. and 6 +36=42. then you add three boxes to make 45.

this probably made no sense. sorry

What is the equation, in vertex form, of the quadratic function that has a vertex at V(−2, −6) and passes through point P(−4, −7)?

Answers

Answer:

            f(x) = -¹/₄(x + 2)² - 6

Step-by-step explanation:

The vertex form of an equation of the parabola:  

                                                         f(x) = a(x - h)² + k

vertex is (-2, -6)  so  h = -2,  k = -6

so:

      f(x) = a(x - (-2))² + (-6)

      f(x) = a(x + 2)² - 6

the parabola goes through the point (-4, -7) so for x=-4,  f(x)=-7

  -7 = a(-4+2)²  - 6

  -7 +6 = a(-2)² - 6 +6

 - 1  = a(4)

     a = -¹/₄

Therefore the equation of the parabola in vertex form:

                                 f(x) = -¹/₄(x + 2)² - 6

What is x? please help

Answers

Answer:  x = 44

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

Work Shown:

The three interior angles of any triangle always add to 180

82+54+x = 180

136+x = 180

x = 180-136

x = 44

---------------

Extra info:

If you need the value of y, then,

x+y = 180

y = 180-x

y = 180-44

y = 136

Or you could use the remote interior angle theorem to find y

y = 82+54

y = 136

The value of z is equal to y since these two angles are vertical angles.
