y=2x+6
y=2x+2
Solve y=2x+6 for y
Substitute 2x+6 for y in y=2x+2
y=2x+2
2x+6=2x+2
Add -2x to both sides
2x+6-2x= 2x+2-2x
6=2
Add -6 to both sides
6-6=2-6
0=-4
No Solution
The answer is A because from where it touches -1 it goes down 3 or -3 which is m(the slope) and b(y intercept) is -3.

Answer:
4 cookies
Step-by-step explanation:
Let the number of cookies he sold be c and that of brownies be b.
Assuming that brownies and cookies are the only type of baked goods sold,
b +c= 10 -----(1)
Amount of money received= $20
b(cost of brownie) +c(cost of cookie)= $20
2.50b +1.25c= 20 -----(2)
From (1): b= 10 -c -----(3)
Substitute (3) into (2):
2.50(10 -c) +1.25c= 20
Expand:
2.50(10) +2.50(-c) +1.25c= 20
25 -2.50c +1.25c= 20
-1.25c +25= 20
Being constants to 1 side:
-1.25c= 20 -25
-1.25c= -5
c= -5 ÷(-1.25)
c= 4
Thus, Joe sold 4 cookies.
Answer
$1.25
Step-by-step explanation:
well a quarter is 25 and 4 of them is $1.00 plus 25 = $1.25 cents
x = 27° (A)
Step-by-step explanation:
5x° + (x + 18)° = 180°
(5x + x)° + 18° = 180°
6x° + 18° = 180°
6x° = 180° - 18°
6x° = 162°
x° = 162 ÷ 6
x° = <u>2</u><u>7</u><u>°</u>
So, the value of x is 27° (A)
