Answer:

9

Step-by-step explanation:1/4 *2= 1/4*2/1=2/8

2/8*(4 to the 3ed power)*(4-1)

4 to the 3ed power= 12

2/8*12*(4-1)

4-1=3

2/8*12*3=

2/8*12=24/8

24/8*3= 24/8*3/1=72/8 divied by 6=1 1/2

Answer: 41.58$

Step-by-step explanation:

Answer:

The inverse of this function is a parabola that has been rotated 90 degrees clockwise, with it's vertex at point 1, 0.

So it's domain is x ≥ 1

And it's range is y ≥ -2

Step-by-step explanation:

Given:

f(x) = (x + 2)² - 1

First we find the inverse:

x = (f(x) + 2)² - 1

x - 1 = (f(x) + 2)²

√(x - 1) = f(x) + 2

f(x) =  -2 ± √(x - 1)

Proof below

Step-by-step explanation:

Algebraic Manipulation

It refers to the process of modifying algebraic expressions, often into a simpler form or more easily handled and dealt with.

It also helps us to prove some identities.

We are given the relations:

a + m = n

n = 4a

Substituting the last equation in the first, we have:

a + m = 4a

Subtracting a on both sides of the equation:

m = 4a - a

Simplifying:

m = 3a

Hence proved

Answer:

[tex]\displaystyle Corresponding\:Angles; 40 = x[/tex]

Step-by-step explanation:

Corresponding Angles are congruent, therefore you set both angle measures equal to each other:

[tex]\displaystyle 135° = [3x + 15]° → 120 = 3x; 40 = x[/tex]

I am joyous to assist you at any time.

Hey there!

The answer to your question is [tex]x = 40[/tex]

These are two parallel lines cut by a transversal, which means that they are corresponding angles and, therefore, [tex](3x + 15)[/tex] is equal to [tex]135[/tex]°:

[tex]3x + 15 = 135[/tex]    

Subtract [tex]15[/tex] from both sides:

[tex]3x = 120[/tex]

Divide both sides by [tex]3[/tex]:

[tex]x = 40[/tex]

Have a terrificly amazing day!

Answer:

C

Step-by-step explanation:

So they bought 2 sneakers. A pair of sneakers cost $6.49. Multiply that by 2, and you get $12.98.

Then they bought a pair of flip flops. So one pair is $0.99. Add that to the $12.98 you got and now you have $13.97.

They also got a pair of flats. One pair is $7.19, so add that to your $13.97 and you now have $21.16.

They also have to pay $1.75 tax, meaning you add that to the $21.16 you have which makes $22.91 total.

But they said how much change they would get from $30 so we're not done yet. So subtract $22.91 from $30 and your answer will be $7.09 which is C.

Answer:

y= 1 and X=4

Step-by-step explanation:

8x +7y =39

8x +2y =34

elimination method(we multiply 8x+7y=39 or 8x + 2y= 34 by -1 to eliminate 8x)

lets multiply 8x+7y = 39 by - 1

-8x -7y = -39

8x +2y = 34

(8x-8x)+(2y-7y)= (-39+34)

0 + (-5y) = -5

-5y= -5......dividing both sides by -5

y = 1

8x +2y =34....... substituting y by 1

8x +2(1)= 34

8x + 2= 34

8x = 34-2

8x = 32.....dividing both sides by 8

x = 4

Lets check;

8x +2y = 34

8(4) +2(1) = 34

32 + 2 =34

34 = 34

8x + 7y = 39

8(4) + 7(1) = 39

32 + 7 =39

39 = 39

Answer:

 [tex]^{15} C_{5} = 3,003 \\[/tex]

Step-by-step explanation:

here , we want to evaluate the value of 15 combination 5

Mathematically, we have the general combination formula as follows;

[tex]{n} C^{r} =\frac{n!}{(n-r)!r!}[/tex]

In this case , n is 15 and r is 5

Thus , we have it that;

[tex]^{15} C_{5} = \frac{15!}{(15-5)!5!} \\= \frac{15!}{10!5!} =\frac{15x14x13x12x11x10!}{10!5!} \\=\frac{15x14x13x12x11}{5!} \\\frac{15x14x13x12x11}{5x4x3x2xx1}=3,003\\[/tex]

PLEASE MARK ME AS BRAINLIEST

After evaluating, we get [tex]^{15} C_{5}=3003[/tex]

The combination of selecting r object from n object is given as,

                    [tex]^{n} C_{r}=\frac{n!}{r!(n-r)!}[/tex]

We have to find [tex]^{15} C_{5}[/tex].

         [tex]^{15} C_{5}=\frac{15!}{5!*10!} \\\\^{15} C_{5}=\frac{15*14*13*12*11*10!}{(5*4*3*2*1)*(10!)} \\\\^{15} C_{5}==\frac{360360}{120} \\\\^{15} C_{5}=3003[/tex]
