7. y=-3/2x+8 (3rd answer choice)

substitute
-4=-3/2(8)+b
-4=-24/2 +b
-4=-12+b
+12 both sides
8=b

so equation would be...

y=-3/2x+8 (3rd answer choice)




8. y=-5x-17 (2nd answer choice)

substitute
-2=-5(-3)+b
-2=15+b
-15 both sides
-17=b

so the equation would be...

y=-5x-17 (2nd answer choice)


check your work by substituting each (x,y) value into the final equations if you want. hope this helps :))

3. A regular hexagon has six equilateral triangles with a common
hichkok12 [17]

Answer:

if the height of the triangle is 8 in, its side is 9.2379, and this side is also the side of the hexagon, so the perimeter is 6*9.2379 = 55.43 in

Step-by-step explanation:

As the hexagon is regular, each of those triangles will also be regular.

So if the height of one triangle is 8 inches, we can find the side of the triangle with the height formula of a regular triangle:

height = side * sqrt(3)/2

8 = side * 0.866

side = 8/0.866 = 9.2379

The side of the triangle will also be the side of the hexagon. So the perimeter of the hexagon will be:

P = 6 * 9.2379 = 55.43 inches

5/3v = 125/7<br> PLEASE HELP
Oxana [17]

Answer:

v =7/75

Step-by-step explanation:

5/3v = 125/7

\frac{5}{3v} = \frac{125}{7}  cross multiply

5*7 = 125 *3v

35 = 375v divide by 375

v = 35/375

v =7/75
