What are the 2 numbers when 30 is the product and -11 is the sum

MArishka [77]

the answer would be -5 and -6.

-5 + -6 = -11 and -5 * -6 = 30 because when multiplying, you cancel out the negative sign when you've got an even amount of negatives.

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle f(x) = \frac{1}{3} - \frac{1}{21}x$

Step 2: Find inverse

Rewrite: $\displaystyle y = \frac{1}{3} - \frac{1}{21}x$
Swap: $\displaystyle x = \frac{1}{3} - \frac{1}{21}y$
[Subtraction Property of Equality] Isolate y term: $\displaystyle x - \frac{1}{3} = -\frac{1}{21}y$
[Multiplication Property of Equality] Isolate y: $\displaystyle -21(x - \frac{1}{3}) = y$
[Distributive Property] Distribute -21: $\displaystyle 7 - 21x = y$
Rewrite: $\displaystyle f^{-1}(x) = 7 - 21x$

Can someone answer this PLEASE!!!

bixtya [17]

Answer:

Equation: 2.75c + 3.59

Step-by-step explanation:

We know that she needs one bag of flour, so that's going to be the constant term. The constant is the one that remains the same, so in this case $3.59. 2.75 is being multiplied by c.
