Answer:

2=w

Step-by-step explanation:

28 = 14 + 7w

-14     -14

14 = 7w

14/7 = 2

7w/7 = w

Hello there.

The answer to this problem would be 2=w. To solve, simply subtract 14 from 28. The answer would be 2. We do this since we cannot add a number to variable, so we just add or subtract the number to number. Finally, divide both sides by 7 since you want to get rid of 7w. Then your answer should be 2=w.

HELP! Giving branliest to who answers!!!
WARRIOR [948]

Answer: A. -1.8

Step-by-step explanation: Hi there!

First, we have to see the constant rate of change in the x and y values.

For x: 2

For y: -3.6

If the slope is m=y/x

then we can do

-3.6/2

that simplifies to

-1.8/1

which is

-1.8

Hope this answer helps you!

Its y=3/4x+3

you can solve it

-3x+4y=12

add 3x both sides

4y=3x+12

divide 4 by both sides

y=3/4x+4

Y = 3x2 − 18x − 19.
Crank

Answer:

  A) y = 3(x -3)^2 -46

  B) (3, -46)

  C) look at the y-coordinate of the vertex

Step-by-step explanation:

A) Factor the leading coefficient from the variable terms.

  y = 3(x^2 -6x) -19

Inside parentheses, add the square of half the x-coefficient. Outside, subtract the same value.

  y = 3(x^2 -6x +9) -19 -3(9)

  y = 3(x -3)^2 -46

__

B) Compared to the vertex form, ...

  y = a(x -h)^2 +k

we find a=3, (h, k) = (3, -46).

The vertex is (3, -46).

__

C) The vertex is an extreme value (as is any vertex). The sign of the leading coefficient tells you whether the parabola opens upward (+) or downward (-). This parabola opens upward, so the vertex is a minimum.

If the leading coefficient is positive, the y-coordinate of the vertex is a minimum. If the leading coefficient is negative, the y-coordinate of the vertex is a maximum.
