Answer:
(-2,-3) and (3,2)
Step-by-step explanation:
sub in x-1 into y
x^2 + (x-1)^2 = 13
x^2 + (x-1)(x-1)=13
x^2 + x^2 -2x +1 = 13
2x^2 -2x-12=0
solve for x by factoring (quadratic formula, product sum etc..)
x= -2 and 3
plug in those values into y=x-1 and solve for y
Me toooo! if anyone in these comments could answer my question, that'd be awesome!
Answer:
Step-by-step explanation:
Any parallelogram has the area of the length between the left and right side times the length from the top to the bottom.
Here the horizontal length is easy, it's just 6. it tries to trick you witht he vertical length. You want the straight up nd down line from the top and bottom, which is that 8 on the right. so the area is 6*8
6*8 = 48
Answer: No, there isn't a proportional relationship.
Step-by-step explanation: In these type of problems, always divide. For it to be proportional, the number of children/ apple slices should be the same for all days. But it isn't, the value differs.
Answer:
![t = wR_p [R_p = 1.05]](https://tex.z-dn.net/?f=t%20%3D%20wR_p%20%20%20%20%20%20%20%20%20%5BR_p%20%3D%201.05%5D)
Step-by-step explanation:
<em>For the case of victor: </em>, let total cost be 
and total weight be 
.
So the price rate per 1 pound of blueberries should be,
<em>For general case: </em>1 pound costs 
so 
pound costs 
pounds. So the equation should be,
