Answer:
-6(x-2)=-7(x-3) = False x = 9
Step-by-step explanation:
Solve for x:
-6 (x - 2) = -7 (x - 3)
Expand out terms of the left hand side:
12 - 6 x = -7 (x - 3)
Expand out terms of the right hand side:
12 - 6 x = 21 - 7 x
Add 7 x to both sides:
7 x - 6 x + 12 = (7 x - 7 x) + 21
7 x - 7 x = 0:
7 x - 6 x + 12 = 21
7 x - 6 x = x:
x + 12 = 21
Subtract 12 from both sides:
x + (12 - 12) = 21 - 12
12 - 12 = 0:
x = 21 - 12
21 - 12 = 9:
Answer: x = 9
A
The first equation has slope 6 and y intercept -4. I'd plot y intercept (0,-4) and (1,2), and connect the dots and extend for the first line.
The second equation has slope 5 and y intercept -3. I'd plot y intercept (0,-3) and (1,2), and connect the dots and extend for the second line.
We stumbled on the solution, both lines contain (1,2)
B
I don't like the graphing. This is algebra, not connect the dots.
We have two equations for y, we equate them to find the x where they meet.
6x - 4 = 5x - 3
6x - 5x = -3 + 4
x = 1
y = 6(1) - 4 = 2
Check: y = 5(1) - 3 = 2, good
Answer: (1, 2)

Answer:
$15.55
Step-by-step explanation:
12.50 x 2= 25
1.50 x 2= 3
18%=1.8 x 10(1.8)
25+3=28
28/1.8= 15.555555555555555555
Answer= 15.55
Hope this helps.
The answer is: x=4 and y=5
