Identifying the values a, b, and c is the first step in using the Quadratic Formula to find solution(s) to a quadratic equation.

MatroZZZ [7]

Answer:

To find a b and c in a quadratic equation, the x^2 number is a, so 7x^2 is your a value, your b value is just the x, so your b value is -9, and your c value is the regular number, which is 18. a=7x^2 b=-9x c = 18. So your answer is answer B.

justin is 10 years less than half his father's age. if justin is 12 years old, how old is his father?

postnew [5]

Make an equation:

J = 1/2F - 10

Where 'J' represents Justin's age and 'F' represents his Father's age.

Plug in 12 for J:

12 = 1/2F - 10

Add 10 to both sides:

22 = 1/2F

Divide 1/2 to both sides or multiply by its reciprocal, 2:

F = 44

Anit [1.1K]

Answer:

Dinda received a 32% loss percentage.

Step-by-step explanation:

<u><em>The question in English is</em></u>

Dinda bought a phone for Rp.2,500,000.00. After 5 months, she sells it with

the price of Rp1,700,000.00. What percentage of losses did Dinda receive?

we know that

Rp.2,500,000.00 represent the 100%

so

Using a proportion

Find out what percentage represent the difference between the original value and the final value

$\frac{2,500,000}{100\%}=\frac{2,500,00-1,700,000}{x}\\\\x=100(800,000)/2,500,000\\\\x=32\%$

therefore

Dinda received a 32% loss percentage.
