No you did not

If original function is y= 3x-2 than inverse function is

3x=y+2 => x= (y+2)/3 than when we change the roles

we get inverse function y=(x+2)/3

Good luck!!!

Simplify each of the following ratios. e) 2/3 : 3/2 : 5/8

Snezhnost [94]

Answer:

32/45

Step-by-step explanation:

2/3 : 3/2 : 5/8

Remember, a ratio and a fraction are both division. Therefore you can rewrite the problem like so:

2/3 ÷ 3/2 ÷ 5/8

Dividing fractions is the same as multiplying them by the reciprocal.

2/3 * 2/3 * 8/5

Now simplify:

32/45

32 and 45 have no common factor, hence the final answer is 32/45

2x+5y=20. , -2x+20y=-90. one solution. infinity many ir no solution. use elimination to find your answer

scoundrel [369]

2x+5y=20
X=10-2.5y

-2(10-2.5y)+20y=-90
-20+5y+20y=-90
25y=-70
Y=2.8

2(2.8)+5y=20

5.6+5y=20
5y=14.4
Y=2.88

CHECK:
2(2.8)+5(2.88)=20

Find the point where the graph of -2x+2y=4 crosses the y-axis?

topjm [15]

When graph crosses y-axis, x=0

-2x+2y=4
-2*0+2y=4
2y=4
y=2

x=0, y=2,
so point is (0,2).
