Answer:
<h2>y + 1 = 5(x - 1)</h2>Step-by-step explanation:
The slope-intercept form:
m - slope
b - y-intercept
Parallel lines have the same slope.
We have y = 5x → m = 5.
The point-slope form:
We have the slope m = 5 and the point (1, -1). Substitute:
The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.
Step-by-step explanation:
Let,
The longer leg = x
The shorter leg = x-7
Hypotenuse = x+7
Using Pythagoras theorem;
Either,
x= 0
Or,
x-28=0 =>x=28
As length cannot be zero, therefore,
Longer side = 28cm
Shorter side = x-7 = 28-7 = 21cm
Hypotenuse = x+7 = 28+7 = 35cm
The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.
