For which values of x does 2x^2=10x?

x = 0; x = 5

Step-by-step explanation:

2x² = 10x

2x² - 10x = 0

2x(x - 5) = 0

x = 0; x = 5

The values of x for which it is true that    are:

and

Step-by-step explanation:

We have the following equation

To solve the equation subtract 10x on both sides of the equation

Now take the variable x as a common factor

Then the equation is equal to 0 when x = 0 or when x = 5

a. is correct

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
