It’s just 2(5(3y)-7) or 2(15y-7), which is 30y-14.

2(5b-7), you can input b as 3y
2(5(3y)-7) —> 2(15y-7) —> 30y -14
—> 30y = 14 —> y = 14/30 —> y = 4.6667

Lisa’s age is 4 years older than three times sammy’s Age. Lisa is 28 years old let s represent sammy’s Age
mel-nik [20]

Answer:

Sammy is 8 years old

Step-by-step explanation:

3s + 4 = 28 is the equation you need to use you have to get s on its own to find Sammy's age

3s + 4 = 28    subtract 4 from both sides

3s = 24      divide both sides by 3

s = 8      Sammy is 8 years old

Please Help I will give out brainliest
gizmo_the_mogwai [7]

Answer:

when y=1 then x=0.5

Step-by-step explanation:

The graph is provided.

The equation y=4x-1 can be graphed by first graphing the -1 which is the y-intercept in the y=mx+b form. 4=m that is our slope. you can find the lines second point by moving 4 up and 1 to the right. rise/run =4/1. So when you move 4 up and 1 right you get another point on the line (1,3).

You can find out x=0.5 when y=1 by just tracing your finger over the graph and the point when y equals 1 the line intercepts x=0.5. Another screenshot is given.

I hope this helps!
