Answer:
in the forth line of the equation it should be this
-6x+10=4x+20
-6x-4x=20-10
-10/-10x=10/-10
x=-1
Answer:
-1/5x -4/5 = y
Step-by-step explanation:
f(x) = -5x -4
y = -5x-4
Switch x and y
x = -5y -4
Solve for y
Add 4
x+4 = -5y
Divide by -5
-1/5x - 4/5 = -5y/-5
-1/5x -4/5 = y
Answer:
No, since 832 ≠ 900, using Pythagorean theorem, the width should be 18 in
Step-by-step explanation:
It is better to type the question in the 'Question' than the fact that you need help so that we can start seeing the problem immediately.
A rectangle has 4 right angles so if l = 24 and w = 16 then you can use the pythagorean theorem to see if this is possible since
24^2 + 16^2 = 30^2 since the diagonal is the hypotenuse of the triangles formed by the diagonal in the rectangle.
576 + 256 ≠ 900, since the left side is 832 and the right side is 900
It would be more correct if the width is 18 since 576 + 18^2 = 900
Answer:
x = 15
Step-by-step explanation:
you have a straight line and a straight line measures 180. You have a 90 degree symbol.
180 = 90 + 47 + 2x + 13
180 = 150 + 2x Subtract 150 from both sides of the equation
30 = 2x Divide both sides by 2
15 = x
