Answer: 81
Concept:
When a number is being squared, to being put to any power, it means the number multiplies itself by the amount of times indicated by the exponent.
For example, if 3 is to the 3rd power, then it would appear to be 3 × 3 × 3.

Find the are of the shaded region
what is the solution to 6x-(3-1)=2
Answer:
x= 2/3
Step-by-step explanation:
So, uh- First you subtract the numbers
6x-(3-1)=2
6x-(2)=2
Then you multiply the numbers
6x-1 ⋅ 2= 2
6x-2=2
(Rest of the steps:)
add 2 to both sides of teh equation

1)what is the measure of the segment AB
2)what is the measure of segment CD
how so?
Answer:
AB = 18, CD = 16
Step-by-step explanation:
The 3 segments make the whole line , that is
AB + BC + CD = AD , substitute values
AB + 20 + (BD - BC) = 54
AB + 20 + (36 - 20) = 54
AB + 20 + 16 = 54
AB + 36 = 54 ( subtract 36 from both sides )
AB = 18
-----------------------------------------------------
BC + CD = BD , substitute values
20 + CD = 36 ( subtract 20 from both sides )
CD = 16

Which of the following is the equation of the line that has x-intercept -2 and y-intercept -6?
А. y=-3x - 6
B. y=-2x - 6
C. y=-6x-2
D. y = 3x - 2
Answer:
a
Step-by-step explanation:
y=mx+c, where c is the y-intercept. hence,
y=mx-6
at the x-intercept, y=0 and x = -2
0 = m(-2)-6
2m = -6
m = -3
y = -3x-6
Answer:
a
Step-by-step explanation:
0 = m(-2)-6
M = -3

I hope I helped you^_^
Answer:
w raised to the power of 10
Step-by-step explanation:
When you have a power raised to a power, you multiply the exponents.
You can check by using a real number for the variable
(2²) raised to the power of 5
4 raised to the power of 5 = 4 x 4 x 4 x 4 x 4 = 1024
5x2 = 10

square root of the quantity x minus 2 end quantity plus 8 equals x
solve for x
Answer:
x = 11.
Step-by-step explanation:
√(x - 2) + 8 = x
√(x - 2) = x - 8
Square both sides:
x - 2 = (x - 8)^2
x - 2 = x^2 - 16x + 64
x^2 - 17x + 66 = 0
(x - 6)(x - 11) = 0
x = 6, 11.
With this type of question we could have extraneous roots so:
Check these 2 roots:
x = 6:
√(2 - 6) + 8 = √(-4)+8 <----- has no real value so this is not a root,
x = 11:
√(11-2) + 8 = 11 < ----Checks out.
Answer:
x = {6, 11}Step-by-step explanation:
[tex]\sqrt{x-2} + 8=x[/tex][tex]\sqrt{x-2} = x - 8[/tex]x - 2 = (x - 8)²x² - 16x + 64 = x - 2x² - 17x + 66 = 0x = (17 ± [tex]\sqrt{17^2- 4*66}[/tex]) / 2x = (17 ± 5)/2x = 11x = 612.

find the coordinates of the points of intersection of the line 2x+3y+2=0 with the curve 2xy=-1
no spam plz fast
The point of intersection of the line 2x+3y+2=0 with the curve 2xy = -1 will be (1/2, - 1) and (1/6, 1/3).
What is substitution method?To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The equation of lines are,
⇒ 2x + 3y + 2 = 0
⇒ 2xy = - 1
Now,
Since, The equation of lines are,
⇒ 2x + 3y + 2 = 0 ..(i)
⇒ 2xy = - 1 ..(ii)
From (ii);
⇒ 2xy = - 1
⇒ x = - 1/2y
Put above value in (i), we get;
⇒ 2 × - 1/2y + 3y + 2 = 0
⇒ - 1/y + 3y + 2 = 0
⇒ - 1 + 3y² + 2y = 0
⇒ 3y² + 2y - 1 = 0
⇒ 3y² + 3y - y - 1 = 0
⇒ 3y (y + 1) - 1 (y + 1) = 0
⇒ (3y - 1) (y + 1) = 0
⇒ y = 1/3
And, y = - 1
So, The value of x is,
⇒ x = - 1/2y
⇒ x = - 1/2 × - 1
⇒ x = 1/2
And, x = - 1/2 × 1/3
⇒ x = 1/6
Thus, The intersection point on the lines = (1/2, - 1) and (1/6, 1/3)

Answer:
Step-by-step explanation:
the equatoin is 4x+77=497
and x is the hours spent
so solving it you subtract 77 from 497 which is 420 and 420/4 is equal to 105
Point C is located between points B and D. Also BC = 5x + 7, CD = 3y + 4, BD = 38, and BD = 2x + 8y. Find the values of x and y
Using location of points and a system of equations, it is found that:
The value of x is 3.The value of y is 4.----------------------------------
Point C is located between points B and D means that:
[tex]BD = BC + CD[/tex]
----------------------------------
We are given that:
[tex]BC = 5x + 7[/tex][tex]CD = 3y + 4[/tex][tex]BD = 38[/tex][tex]BD = 2x + 8y[/tex]From this, two equations can be built.
[tex]2x + 8y = 38[/tex]
Dividing both sides by 2:
[tex]x + 4y = 19[/tex]
[tex]x = 19 - 4y[/tex]
----------------------------------
Finding y:
[tex]BC + CD = BD[/tex]
[tex]5x + 7 + 3y + 4 = 38[/tex]
[tex]5x + 3y + 11 = 38[/tex]
[tex]5x + 3y = 27[/tex]
Since [tex]x = 19 - 4y[/tex]
[tex]5(19 - 4y) + 3y = 27[/tex]
[tex]95 - 20y + 3y = 27[/tex]
[tex]17y = 68[/tex]
[tex]y = \frac{68}{17}[/tex]
[tex]y = 4[/tex]
----------------------------------
Finding x:
[tex]x = 19 - 4y = 19 - 4(4) = 19 - 16 = 3[/tex]
The value of x is 3.
The value of y is 4.
