Answer: Y=2.50x+b
Step-by-step explanation:
Thats not the whole answer, you didnt attach the graph but what you need to do is find the y-intercept and put that into b and theres your equation. The y-intercept(B) represents the initial money that joe had in his savings the 2.50x part or the slope is the money that he states he can add each week.

Answer:
The other legs are 9 and 9√3
Step-by-step explanation:
The longer side of a 30-60-90 degree rectangle is 18.
The other legs will be

and

Where x is the longest side, which is given as 18.
Therefore one leg will be:

and the other leg will be:

Heya !
Given expression -

Subtracting 25 both sides ,

Dividing by 3 on both sides ,

Therefore ,
We can represent the base as z and the height as 2z+6. We are going to use the formula A=1/2*b*h and solve for z
180=1/2*z*(2z+6)
360=2z^2+6z
0=2z^2+6z-360
0=2(z^2+3z-180)
0=(z+15)(z-12)
So z=-15 and 12 but it must be positive so then the base is equal to 12
When we plug this into 2z+6 we get 30 for the height
2(12)+6=30
Hope this helps
