Answer:
(3, 2)
Step-by-step explanation:
y = 3x - 7
2x + 5y = 16
Solve for x:
2x + 5(3x - 7) = 16
2x + 15x - 35 = 16
17x = 51
x = 3
Solve for y:
y = 3(3) - 7
y = 9 - 7
y = 2

Answer:

Step-by-step explanation:
Existing walkway
l = 10 ft
w = 4 ft
A₁ = lw = 10 ft × 4 ft = 40 ft²
New walkway
Expanding a measurement by 25 % means that you multiply it by a factor of 1.25.
New length = 10 × 1.25 = 12.5 ft
New width = 4 × 1.25 = 5 ft
A₂ = lw = 12.5 ft × 5 ft = 62.5 ft²
Increase in area
A₂ - A₁ = 62.5 – 40 = 22.5 ft²
The increase in area is 
Answer:
y= -1/2x+5
Step-by-step explanation:
The formula you need to use is (y-y1)=m(x-x1)
x1=the x point provided
y1=the y point provided
m=the slope
Simply plug the numbers into the equation to start.
(y-3)= -1/2(x-4) Now we need to distribute the slope to both terms inside the parenthesis.
-1/2(x)= -1/2x
-1/2(-4)= 2 Now you put them back into the equation.
(y-3)= -1/2x+2
At this point you can get rid to the parenthesis around y-3 because it is basically saying to take it times 1.
y-3= -1/2x+2 Finally to get y alone you would add 3 to both sides.
+3 +3
y= -1/2x+5
