Answer:
A because it's most likely to be like that at tryouts
Here is your answer in the format of a PNG file.
The last would be a < 40 if you'd be going under $40.
Answer:
x=-4
y=1
Step-by-step explanation:
For the given system of equations,
2.5x-3y=-13.....eqn(1)
3.25x-y=-14.....eqn(2)
We first make y the subject of eqn (2)
This implies that,
y=3.25x+14.....eqn(3)
We substitute eqn (3) into eqn (1)
2.5x-3(3.25x+14)=-13
2.5x-9.75x-42=-13
-42+13=9.75x-2.5x
-29=7.25x
Dividing through by 7.25, we obtain
x=-4
We now put the value of x into eqn (2)
3.25(-4)-y=-14
This implies that,
-13+14=y
y=1
The you find this is by first finding the slope. You do this by finding the difference between both x values and then both y values. You get 12(x), 6(y) then write it as a fraction. it is 12/6 which simplifies to 2. 2 is our slope. then you write it out in slope intercept form (y=mx+b) and plug in your numbers. pick one set of original points an put them in to x and y. now you just solve for b. this gives you -9 as b. you put it together to get
y=2x-9
hope this helps!!!! :)
