How can the additive inverse be used to evaluate the problem below -3-(-6)

1 answer:

3 0

Since there are two subtraction signs next to each other, you can look at them both as one plus sign. So now the problem is -3+6 which equals 3.( Hope this helps)

-3-(-6)
-3+6
3

the equation y=15x can be used to determine the amount of money y pauli's pizzeria makes by selling x pizzas . the graph shows t

abruzzese [7]

Answer:

Pauli's pizzeria make more money per pizza

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find out the slope of the graph of Leo's pizzeria

looking at the graph take the point (2,24)

The graph show a proportional relationship (the line passes through the origin)

The slope is m=y/x

we have

For x=2, y=24

substitute

m=24/2=$12 per pizza sold

The linear equation is

y=12x

step 2

Compare the slopes

Pauli's pizzeria

we have

y=15x -----> slope m=$15 per pizza sold

Leo's pizzeria

we have

y=12x -----> slope m=$12 per pizza sold

$15 per pizza sold > $12 per pizza sold

therefore

Pauli's pizzeria make more money per pizza

When completing the square on the equation c2 + 110 = 12, the resulting solution is: It

Delvig [45]

Answer:

$c=1$ and $c=-12$

Step-by-step explanation:

The correct equation is:

$c^2+11c=12$

To solve by completing the square method.

Solution:

We have:

$c^2+11c=12$

In order to solve by completing the square method we will carry out the following operations to the given equation to get a perfect square binomial.

We can write as:

$c^2+2.\frac{11}{2}c=12$

$c^2+2.\frac{11}{2}c+(\frac{11}{2})^2-(\frac{11}{2})^2=12$

$(c+\frac{11}{2})^2-(\frac{11}{2})^2=12$ [As $c^2+2.\frac{11}{2}c+(\frac{11}{2})^2=(c+\frac{11}{2})^2$ ]

Adding both sides by $(\frac{11}{2})^2$

$(c+\frac{11}{2})^2-(\frac{11}{2})^2+(\frac{11}{2})^2=12+(\frac{11}{2})^2$

$(c+\frac{11}{2})^2=12+\frac{121}{4}$

Taking LCD to add fraction.

$(c+\frac{11}{2})^2=\frac{48}{4}+\frac{121}{4}$

$(c+\frac{11}{2})^2=\frac{169}{4}$

Taking square root both sides.

$\sqrt{(c+\frac{11}{2})^2}=\sqrt{\frac{169}{4}}$

$c+\frac{11}{2}=\pm\frac{13}{2}$

Subtracting both sides by $\frac{11}{2}$ :

$c+\frac{11}{2}-\frac{11}{2}=\pm\frac{13}{2}-\frac{11}{2}$

$c=\pm\frac{13}{2}-\frac{11}{2}$

So, we have:

$c=\frac{13}{2}-\frac{11}{2}$ and $c=-\frac{13}{2}-\frac{11}{2}$

$c=\frac{2}{2}$ and $c=\frac{-24}{2}$

$c=1$ and $c=-12$ (Answer)
