Answer:

When e= 7 and f = 2, then $5f^2-2e$ is than $\frac{6(e+f)}{f}$ .

Step-by-step explanation:

We are given that:

e= 7
f= 2

Using this, we can plug into the values into the following equation in order to figure out how the two equation relate.

$5f^2-2e$
$5(2)^2-2(7)$
$5(4)-14$
$20 - 14$
$6\\$

Now that the first equation is solved, lets solve the second equation.

$\frac{6(e+f)}{f}$
$\frac{6(7+2)}{2}$
$\frac{6* 7 + 6 *2}{2}$
$\frac{42 + 12}{2}$
$\frac{54}{2}$
$27$

Therefore, when e= 7 and f = 2, then $5f^2-2e$ is than $\frac{6(e+f)}{f}$ .

Jully bought 3 slices of cheese pizza and 4 slices of pepperoni pizza for $18.00. Christian bought 3 slices of cheese pizza and

andrew11 [14]

Answer:

$2.00

Step-by-step explanation:

You can form an equation with these statements, x being the price of cheese pizza and y being the price of pepperoni. Making the equation,

3x+4y=18

3x+2y=12

Solving the equation,

3x+4y=18

6x+4y=24

-3x=-6

x=2

y=3

Solving another way,

2y=6

y=3

x=2

Therefore, the answer is $2.00

Evaluate Dx / ^ 9-8x - x2^

Solnce55 [7]

It depends on what you mean by the delimiting carats "^"...

Since you use parentheses appropriately in the answer choices, I'm going to go out on a limb here and assume something like "^x^" stands for $\sqrt x$ .

In that case, you want to find the antiderivative,

$\displaystyle\int\frac{\mathrm dx}{\sqrt{9-8x-x^2}}$

Complete the square in the denominator:

$9-8x-x^2=25-(16+8x+x^2)=5^2-(x+4)^2$

Now substitute $x+4=5\sin y$ , so that $\mathrm dx=5\cos y\,\mathrm dy$ . Then

$\displaystyle\int\frac{\mathrm dx}{\sqrt{9-8x-x^2}}=\int\frac{5\cos y}{\sqrt{5^2-(5\sin y)^2}}\,\mathrm dy$

which simplifies to

$\displaystyle\int\frac{5\cos 
y}{5\sqrt{1-\sin^2y}}\,\mathrm dy=\int\frac{\cos y}{\sqrt{\cos^2y}}\,\mathrm dy$

Now, recall that $\sqrt{x^2}=|x|$ . But we want the substitution we made to be reversible, so that

$x+4=5\sin y\iff y=\sin^{-1}\left(\dfrac{x+4}5\right)$

which implies that $-\dfrac\pi2\le y\le\dfrac\pi2$ . (This is the range of the inverse sine function.)

Under these conditions, we have $\cos y\ge0$ , which lets us reduce $\sqrt{\cos^2y}=|\cos y|=\cos y$ . Finally,

$\displaystyle\int\frac{\cos y}{\cos y}\,\mathrm dy=\int\mathrm dy=y+C$

and back-substituting to get this in terms of $x$ yields

$\displaystyle\int\frac{\mathrm dx}{\sqrt{9-8x-x^2}}=\sin^{-1}\left(\frac{x+4}5\right)+C$

Step-by-step explanation:

88 blue marbles, 55 green marbles, and 88 red marbles =231 marbles

P (blue or red marble) = number of red or blue/ total

= 88+88 / 231

=176/231
