Option c : 9 is the answer.

Explanation:

The expression is 1.2-(-7.8)

We need to determine the subtracted value of the expression.

From the expression we can see that the expression contains two negative signs.

To simplify the expression, we know that, When we multiply two negative numbers then the product is always positive.

This means (-) *(-) = +

Thus, the expression can be written as

1.2+7.8

Adding the two numbers, we get,

1.2+7.8=9

Thus, the value of the expression is 9.

Hence, Option c is the correct answer.

If f(x)=2x^3-x+c and f(2)=10 then what's the value of c?
Goshia [24]

Answer:

c = -4

Step-by-step explanation:

If f(x) = 2x^3 - x + c and f(2) = 10, plug in 2 for the x values in the function and make the function output 10.

10 = 2(2^3) - 2 + c    Now, we only have to deal with one variable, that is c.

10 = 2(8) - 2 + c

10 = 16 - 2 + c

10 = 14 + c

-4 = c    After simplifying, we get that c is -4.

To check this, plug in 2 for x, and -4 for c in the function. If the function produces 10 as the result, the halleluja!

f(2) = 2(2^3) - 2 - 4

f(2) = 2(8) - 2 - 4

f(2) = 16 - 2 - 4

f(2) = 10

If p+q has the value that is exactly 1/3 less than p what is the value of q
solmaris [256]

Answer:

q = - \frac{1}{3} p

Step-by-step explanation:

\frac{1}{3} less than p = \frac{2}{3} p

Thus

p + q = \frac{2}{3} p ( multiply through by 3 to clear the fraction )

3p + 3q = 2p ( subtract 3p from both sides )

3q = - p ( divide both sides by 3 )

q = - \frac{1}{3} p
