Answer:

x=0 or x=2 or x=2

Step-by-step explanation:

Step 1: Factor left side of equation.

10x(x−2)(x−2)=0

Step 2: Set factors equal to 0.

10x=0 or x−2=0 or x−2=0

x=0 or x=2 or x=2

sorry if it is not right

Solve for x by simplifying both sides of the equation, then isolating the variable.

x=0

Suppose that y varies directly with x and y=5 when x=6. What is y when x=5? Be sure to simplify your answer.
Charra [1.4K]

Answer:

y = \frac{25}{6}

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 5 when x = 6

k = \frac{y}{x} = \frac{5}{6}

y = \frac{5}{6} x ← equation of variation

When x = 5, then

y = \frac{5}{6} × 5 = \frac{25}{6}

What is the value of ?
Ede4ka [16]
Remember
\frac{x^m}{x^n}=x^{m-n}
and
x^{-m}=\frac{1}{x^m}

so
\frac{3^2}{3^4}=3^{2-4}=3^{-2}=\frac{1}{3^2}=\frac{1}{9}

Please help me! if correct will mark brainliest
Wewaii [24]

Answer:

17.5

Step-by-step explanation:

formula:

y=k(x)

direct variation^^^

y=7, x=2

substitute it in the formula

7=(k)2 or 7=2k

7/2 or 3.5= k, k is the constant

now substitute k to the problem

y=5k

y=5(3.5)

y=17.5
