Answer:

y=2x-6

Step-by-step explanation:

y+4=2(x-1)

Subtract 4 to both sides of the equation:

y+4-4=2(x-1)-4

y=2(x-1)-4

Distribute the 2:

y=2x-2-4

y=2x-6

Where 2 is the slope and -6 is the y - intercept.

Tell what you would do to isolate the variable. -5c = 5/24

Masteriza [31]

To isolate the variable here is what you would do:

−5c= $\frac{5}{24}$

Step 1: Divide both sides by -5.

$\frac{-5c}{-5}$ = $\frac{5}{24}$ (A five was supposed to go underneath the 24 to show the division but whatever)

Answer: c= $\frac{-1}{24}$

Answer:

$\large\boxed{39^o}$

Step-by-step explanation:

$m\angle ABC=90^o\\\\m\angle ABC=m\angle ABD+m\angle DBC\\\\m\angle DBC=51^o\\\\\text{Substitute:}\\\\m\angle ABD+51^o=90^o\qquad\text{subtract }\ 51^o\ \text{from both sides}\\\\m\angle ABD=39^o$

The right triangle above has height h centimeters and hypotenuse t centimeters. What is the area, in square centimeters, of the

White raven [17]

Answer:

$A = \frac{h\sqrt{t^{2} - h^{2}}}{2}$

Step-by-step explanation:

Right triangle:

height h, width w, hypotenuse h

Area is: $A = \frac{h*w}{2}$

Pytagoras theorem: $h^{2} + w^{2} = t^{2}$

In this question:

To find the area, in terms of h and t, we have to write w as a function of h and t. So

$h^{2} + w^{2} = t^{2}$

$w^{2} = t^{2} - h^{2}$

$w = \sqrt{t^{2} - h^{2}}$

So the area is:

$A = \frac{h*w}{2}$

$A = \frac{h\sqrt{t^{2} - h^{2}}}{2}$
