Answer:
Step-by-step explanation:
We first need to define a couple of variables. Let s = the cost of 1 squash and z = the cost of 1 zucchini.
Now lets translate the words into algebra:
"The cost of 5 squash and 2 zucchini is $1.32" ===> 5s + 2z = 1.32
"Three squash and 1 zucchini cost $0.75" ===> 3s + z = 0.75
There are several ways to solve systems of equations. Let's use substitution. We can find what z equals in terms of s by manipulating the second equation:
3s + z = 0.75
-3s -3s
------------ -------------
z = -3s +0.75
Now lets substitute (-3s + 0.75) into the first equation for z, then solve for s:
5s + 2(-3s + 0.75) = 1.32
Can you handle it from here?
(Hint: Once you have solved for s, you can substitute that value back into either of the equations and solve for z.)
Answer:
-20
Step-by-step explanation:
It is like the opposite number. Because 20 is positive its inverse is negative 20.

Answer:
0 or 0/6
Step-by-step explanation:
3+6=9
-2+0=-2
0/6=0
A(-5,5)
B(4,5)
C(2,0)
D(-5,-2)
AB,BC,CD,DA
AB = [4-(-5)),5-5]=[9,0]
Lenght
BC = [2-4,0-5]=[-2,-5]
Lenght
CD = [-5-2,-2-0]=[-7,-2]
Lenght
DA =[-5-(-5),-2-5]=[0,-7]
Lenght
sorted from longest to shortest:
AB, CD,DA,BC
Okay so here to find the answer you have to solve for any one by setting them in y=mx+b form
y=-3x+7 x=-2y-16
2y=-x-16 6=-2y-16
x=6 22=-2y
-11=y
