Answer:
(2, 1 )
Step-by-step explanation:
Given the 2 equations
y = 6x - 11 → (1)
- 2x - 3y = - 7 → (2)
Substitute y = 6x - 11 into (2)
- 2x - 3(6x - 11) = - 7 ← distribute and simplify left side
- 2x - 18x + 33 = - 7
- 20x + 33 = - 7 ( subtract 33 from both sides )
- 20x = - 40 ( divide both sides by - 20 )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = 6(2) - 11 = 12 - 11 = 1
Solution is (2, 1 )

Answer:
The width cannot be negative, so w = 9, l = 16.
Step-by-step explanation:
w = the width
l = w +7
A = l · w
A= w ( w + 7 )
144 = w2 + 7w
0 = w2 + 7w - 144
0 = ( w - 9 )( w + 16 )
The width cannot be negative, so w = 9, l = 16.
Given:
The function is
To find:
The value of f(-1).
Solution:
We have,
Putting x=-1, we get
Therefore, the value of f(-1) is -12.
Bill received $144 more than Pam.
Explanation:
To create the ratio, we can divide 360 by 5 which equals 72.
3x72= 216
360
The ratio that is proportionate to 3:5 is 216:360
So, 360 - 216 = 144
