Answer:
Hi, your answer is y=
-3
Step-by-step explanation:
We will use the slope-intercept formula which is
We will use two points in this case I'll use
(-2,-2) and (-8,1)
=
which can be simplified as 
Your Y will be -3
which your final answer will be y=-1/2x-3
Hope this helps :)
Answer:
A)
Step-by-step explanation:
Answer:
$10
Step-by-step explanation:
Let a = the amount Angela has saved.
Let e = the amount Eli has saved.
"Eli has saved $8 more than 1/3 of Angela's savings."
e = a/3 + 8
"If they each save $10 more." then
Eli will have: e + 10
Angela will have a + 10
"Eli will have saved $4 more than Angela's savings."
e + 10 = a + 10 + 4
This equation simplifies to: e = a + 4
We have a system of two equations in two variables.
e = a/3 + 8
e = a + 4
Since both equations are solved for e, we just equate the right sides.
a/3 + 8 = a + 4
Subtract a/3 from both sides. Subtract 4 from both sides.
a/3 - a/3 + 8 - 4 = a - a/3 + 4 - 4
4 = (2/3)a
Multiply both sides by 3/2
(3/2)4 = (3/2)(2/3)a
6 = a
a = 6
Angela has $6.
e = a + 4 = 6 + 4 = 10
Eli has $10.
(12/30)x100 is 40%
This is percent of incorrect answers. The total percent must be 100% so subtract 100-40=60%.
60% answers were answered correctly.
