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:
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.
find the value of x. What kind of angles are these?
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]

In a video game, Clare scored 50% more points than Tyler. If c is the number of points that Clare scored and t is the number of points that Tyler scored, which equations are correct? Select all that apply.
c = 1.5t
c = t + 0.5
c = t + 0.5t
c = t + 50
c = (1 + 0.5)t
Answer:
c = t + 0.5t

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]

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

What is the domain and range of the inverse of: f (x)= (x + 2)² - 1
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)
4. Given: a + m = n, n= 4a; Prove: m = 3a
Answer:
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

8x+ 7y =39
8x + 2y = 34
What is x and y
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
