Answer:
16√5
Step-by-step explanation:

Answer:
y = 4x -5
Step-by-step explanation:
Gradient is also known as slope . The gradient of a line is represented by the equation
Slope (m) = y - y1/ x - x1
Where m = 4 , x1= 1 and y1 = -1
Imputing the values into the equation
m = y - y1/ x - x1
4 = y - -1/x - 1
Cross multiply, we have
y + 1= 4(x - 1)
Expand
y+1= 4x - 4
Subtract 1 from both sides
y+1-1= 4x -4-1
y = 4x -5

Answer:
x=32, y=17
Step-by-step explanation:
Difference between two numbers is 15:
x-y=15
Greater number (x) is two less than twice the lesser number:
x=2y-2
-----
x-y=15,
x=2y-2.
x-y-x=15-2y+2
-y=15-2y+2
y=15+2
y=17
-----
x-y=15
x-17=15
x=17+15
x=32
