Answer:

you will need to find the difference (subtract) between two of the y points then do the same for the x points and put to difference of y on top of x and there is you slope using a graph( or if eaven, will come put as a whole number

Answer:

Solving the equation : $y+\frac{y}{a}=b\:if\:a\neq\: -1$ for y we get $\mathbf{y= \frac{ab}{a+1},\:if\:a\neq -1}$

Step-by-step explanation:

We need to solve for y the equation: $y+\frac{y}{a}=b\:if\:a\neq\: -1$

We need to find value of y

Solving:

$y+\frac{y}{a}=b$

Taking LCM of a, 1 we get a

$\frac{a*y+y}{a}=b\\\frac{ay+y}{a}=b$

Multiply both sides by a, a will be cancelled on left side

$a(\frac{ay+y}{a})=ab\\ay+y=ab$

Taking y common from left side:

$y(a+1)=ab$

Divide both sides by a+1

$\frac{y(a+1)}{a+1}=\frac{ab}{a+1}\\y= \frac{ab}{a+1},\:if\:a\neq -1$

So, Solving the equation : $y+\frac{y}{a}=b\:if\:a\neq\: -1$ for y we get $\mathbf{y= \frac{ab}{a+1},\:if\:a\neq -1}$

Which ordered pair could not be the coordinates for a clockwise rotation of the point W(-3, 4)?

Eduardwww [97]

Step-by-step explanation:

<em>Look at the picture.</em>

Any pair of choice can be the coordinates of the rotation of the point

W (-3, 4) clockwise.

All points have the same distance from the beginning.

The formula of a distance between the origin and a point (x, y):

$d=\sqrt{x^2+y^2}$

W(-3, 4)

$d=\sqrt{(-3)^2+4^2}=\sqrt{9+16}=\sqrt{25}=5$

(3, -4)

$d=\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5$

(4, 3)

$d=\sqrt{4^2+3^2}=\sqrt{9+16}=\sqrt{25}=5$

(-4, -3)

$d=\sqrt{(-4)^2+(-3)^2}=\sqrt{9+16}=\sqrt{25}=5$

(-4, 3)

$d=\sqrt{(-4)^2+3^2}=\sqrt{9+16}=\sqrt{25}=5$

How do I find the missing side

vekshin1

Answer:

x = 11.8639

Step-by-step explanation:

cos∅ = adjacent / hypotenuse

Since we are dealing with right triangles, we can use trig to help solve for missing values:

cos22° = 11/x

xcos22° = 11

x = 11/cos22°

x = 11.8639
