Answer:

y = 7

Step-by-step explanation:

-4y+6y-5=9

Add -4y and 6y

2y-5=9

Move all terms not containing  y  to the right side of the equation.

2y=14

Divide both sides by 2

y=7

The base of a triangle is 2 more than twice the height of the triangle. Find the measure of the base and the height if the area
vekshin1
B = 2 + 2H 
A = 20 ft^2
H = H

Since the Area of a Triangle is Base * Height then the formula should be:
A = BH
20 = H(2+2H)
20 = 2H^2 + 2H
0 = 2H^2 + 2H - 20 

Find the zeros of the quadratic equation through substituting the values of a,b, and c. You will get the zeros of x = 2.7 and -3.7. The only thing that would make sense is you use the x=2.7 because there are no negative heights.

Since b = 2h+2 
b= 2(2.7) + 2
b= 5.4 + 2 
b=7.4

I don't know where you got 4 and 10, but what I got is different.

Rewrite this function using function notation.<br> -3.7x = 3-y
Ivanshal [37]

Answer:

f(x) = 3.7x + 3

Step-by-step explanation:

Using the fact that y = f(x), then rearrange the equation making y the subject.

- 3.7x = 3 - y ( add y to both sides )

y - 3.7x = 3 ( add 3.7x to both sides )

y = 3.7x + 3 , that is

f(x) = 3.7x + 3
