Answer:
The Answer is w - 982 = 922 because it whatever money he took from the 982 lead to 922
Step-by-step explanation:
For this case we have the following variables:
x: number of months
f (x): number of caps sold
The function that models the problem is given by:
By the time the store sells 64 caps we have:
From here, we clear the number of months:
Answer:
the store sells 64 caps in 3 monts
A. month 3
1. Solving an order system
2. Let us solve this one by combining the two equations:
2x – y = 7
2y = 4x – 14 --> y = 2x – 7
combine:
2x – (2x – 12) = 7
2x – 2x + 7 = 7
0 + 7 = 7
7 = 7
No variable at the end, therefore infinite solutions
3. From the given equations itself, we can see that this
is impossible to have solutions, therefore:
{}
4. y – x = -1 --> y = x – 1
x + (x – 1) = -5
2x – 1 = -5
x = -2
y = x – 1 = -2 – 1 = -3
(-2, -3)
5. x = y
x + x = 4
2x = 4
x = 2 = y
(2, 2)
1 solution
6. x – y = 2 --> x = 2 + y
3 (2 + y) + 2y = 6
6 + 3y + 2y = 6
5y = 0
y = 0
x = 2 + y = 2
(0, 2)
1 solution
7. 4x + (x + 6) = 1
5x + 6 = 1
5x = -5
x = -1
y = x + 6 = -1 + 6 = 5
(-1, 5)
8. x – y = 5 --> x = 5 + y
2 (5 + y) + y = 1
10 + 2y + y = 1
3y = -9
y = -3
x = 5 + y = 5 – 3 = 2
(2, -3)
1 solution

so the answer you got pls mark branlist
Answer:
1 = 68
2 = 68
3 = 125
Step-by-step explanation:
Hey there!
To find angle 1 all we have to do is subtract the given angles from 180 because remember all of the angles in a triangle add up to 180
180-73-39=68
1=68
angle 2 is vertical to angle 1 therefore they are congruent angles so
2 also equals 68
So we know that the interior angles in a 4 sided shape add up to equal 360
so to find 3 we subtract the given angles from 360
360-90-77-68=125
so 3 = 125
