[tex] {9}^{(x + 2)} = {27}^{8} \\ [/tex]
[tex]( { {3}^{2} })^{x + 2} = ({ {3}^{3} })^{8} [/tex]
[tex] {3}^{2 \times (x + 2)} = {3}^{3 \times 8} [/tex]
[tex] {3}^{2(x + 2)} = {3}^{24} [/tex]
Thus :
[tex]2(x + 2) = 24[/tex]
Divide sides by 2
[tex] \frac{2(x + 2)}{2} = \frac{24}{2} \\ [/tex]
[tex]x + 2 = 12[/tex]
Subtract sides 2
[tex]x + 2 - 2 = 12 - 2[/tex]

(2,-4); rotation 180 degrees
Answer:
(-2, 4)
Step-by-step explanation:
Change at least one number in the table so that it DOES represent a function.
Answer:
change 2 to 4
and 1 to 5
1 --> 5
2 --> 10
3 --> 15
4 --> 20
5 --> 24
Step-by-step explanation:
Function means you can have one input for evry one output
so you have to change the 2 and 1 to diffrent numbers like 4 and 5
so now evey imput has their own out put
befor input one it had 5 and 24
and input two had 10 and 20 but changing the number you get one for one
If a circle with a diameter of 4 inches rotates 1000°, what distance will any one spot on
its edge actually travel?
We first convert from degrees to radians multiplying by π/180:
θ = 1000° × π/180 = 17.45 rad
The radius is:
r = d/2 = 4 in /2 = 2 inch
So, The distance traveled is given by the product of the angle in radians and the radius. This is:
d = θr = (17.45 rad)(2 inch) = 34.9 inch

Step-by-step explanation:
Use this new algebraic method to find equations for the line with the following properties:
A slope of −3, passing through the point (15,−50).
Show your work in the sketch box on the left.
Step 1: Substitute values for m, x, and y.
Step 2: Solve equation for b.
Step 3: Rewrite your equation with only m and b.
What is the equation of this line?
Answer:
Y = -3x + 90
Step-by-step explanation:
Y= Mx + b
M - (-3)
X - 15
Y - (-50)
Y = Mx + b
50 = (-3)(15) + b
50 = -45 + b
95 = b
Y = -3x + 90

Question 3 40 pts
An object is attached to a spring that is stretched and released. The equation d = a (cos(bt)) models the distance, d, of the object in inches above or below the rest position as a function of time, t, in seconds. If a = 5 and b = 5 Approximately when will the object be 2 inches above the rest position? Round to the nearest hundredth, if necessary.
Answer:
The object will be 2 inches above the rest position when at approximately 0.23 seconds
Step-by-step explanation:
The given parameters are;
The equation that models the distance, d, of the object in inches above or below the rest position = a×(cos(b·t))
If a = 5 and b = 5, we have;
d = 5 × (cos(5 × t))
When the object is approximately 2 inches above the ground, we have;
d = 2 = 5 × (cos(5 × t))
cos(5 × t) = 2/5
5 × t = cos⁻¹(2/5) ≈ 1.16
t = (cos⁻¹(2/5))/5 ≈ 1.16/5
t ≈ 0.23 s
The object will be 2 inches above the rest position when t ≈ 0.23 s.

Which expression is equivalent to 6(2u)?
(u + 2)6
6 + 2u
(20)6
U + 8
Answer:
There is no answer at all
Given:6(2u)=12u
(u + 2)6=12+6u
6 + 2u= 2u+6
(20)6= 120
U + 8 = u+ 8
Answer:
I would think it should be 6x2u. if u equals 10 then it would be (20)6
Tommy decided to also make a sampler can with a diameter of 2 inches and a height of 3 inches. Tommy calculated that the area of the base was 4 pi inches squared, and multiplied that by the height of 3 inches for a total volume of 12 pi inches cubed. Explain the error Tommy made when calculating the volume of the can.
Answer:
Tommy used diameter instead of radius in calculationStep-by-step explanation:
Givend = 2 inchesh = 3 inchesTo findVolume of the canSolutionVolume formula:
V = πr²hCalculation
V =π(d/2)²h = π(2/2)²(3) = 3π in²Tommy's error is squaring the diameter instead of radius
Answer:
Sample response: Tommy used the diameter instead of the radius in the formula to find the area of the base. The diameter needs to be divided by 2 to find the radius. The correct area of the base is 1 pi square inches. The correct total volume is 3 pi cubic inches.

(x - 18)^2 = 1
Answer:
x=17 or x=19
Step-by-step explanation:
(x−18)^2=1
First, simplify both sides of the equation.
x*2−36x+324=1
Then subtract 1 from both sides.
x^2−36x+324−1=1−1
x^2−36x+323=0
Factor left side of equation.
(x−17)(x−19)=0
Then set factors equal to 0.
x−17=0 or x−19=0
x=17 or x=19
Answer:
Its either x=17 or x=19

David is buying a television that is regularly priced at $450.The television is on sale for 20% off. Sales tax is 7%.Whicj expression will calculate the final price of the television.
Answer:
The final price of the television is $502.20.
Step-by-step explanation:
The information provided is:
CP = $450
d% = 20%
s% = 7%
Compute the final price of the television as follows:
[tex]SP=CP\times (1 + s\%)\times (1-d\%)[/tex]
[tex]=450\times (1+0.20)\times (1-0.07)\\\\=502.2[/tex]
Thus, the final price of the television is $502.20.

what is the slope of a line with endpoints (-11,5) and (5,-7)
Answer:
-6/8
Step-by-step explanation:
Slope=y1-y2/x1-x2
Where (X1,y1) is (-11,5) and (X2,y2) is(5,-7)
Slope=5+7/-11-5
=-12/16
= -6/8
So the slope is -6/8
6-2x=5x-9x+12 what is the value of x
its for savvas realize
Answer:like terms: 5x + -9x = -4x 6 + -2x = -12 + -4x Solving 6 + -2x = -12 + -4x Solving for variable 'x'.
Step-by-step explanation:
6 - 2x = 5x - 9x + 18 - 12 6 - 2x = -4x + 6 -2x = -4x 4x - 2x = 0 2x = 0 x = 0 / 2 x = 0.
Answer:
x=3
Step-by-step explanation:
6-2x=5x-9x+12
6-2x=-4x+12
-2x+4x=12-6
2x=6
x=6/2

A bicycle has a listed price of $811.98 before tax. If the sales tax rate is 7.5%, find the total cost of the bicycle with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
Step-by-step explanation:
811.98*7.5%= 60.898
811.98+60.898= 872.787 round to $872.79
Answer:
$872.88
Step-by-step explanation:
811.98 x 7.5%= 811.98 x 0.075
811.98 x 0.075= 60.90
811.98+60.90= 872.88
If we estimate that 10 people can fit in a 5ft by 5ft area, then what would be your estimate of how many people can fit on a basketball court measuring 94ft by 50ft?
Answer:
1,880 people will fit in 94 ft by 50 ft
Step-by-step explanation:
We can estimate this using the area
For 5 ft by 5ft ; 10 people can fit in an area of 5 * 5 = 25 ft^2
In an area of 94 ft by 50 ft, the number of people that can fit will be;
let’s start with the area
Area = 94 * 50 = 4,700 square feet
10 people will fit in 25 square feet
x people in 4,700 square feet
25 * x = 10 * 4700
25x = 47,000
x = 47000/25
x = 1,880 people
Your subtotal at the store was $58.89. You have a 30% off coupon. If the sales tax rate is 5.5%, what is the total price for your shopping trip?
Answer:
$43.48
Step-by-step explanation:
58.89x.30=17.68
58.89-17.68=41.21
41.21x.055=2.27
41.21+2.27= $43.48
Answer:
$43.49
Step-by-step explanation:
When you take of 30%, multiply by 0.7
When you add 5.5%, multiply by 1.055
Start with $58.89
Take off 30%: 0.7 * $58.89 = $41.22
Add 5.5%: 1.055 * $41.22 = $43.49
I need to know how to graph and use a table to solve for y=3x+0
Answer:
Step-by-step explanation:
On a table, you'd have two columns: one for your input(x) and one for your output(y). If given an x value, put it into the equation to solve for y, and if you have a y value, put it into the equation for x. You can also come up with your own x values and put them into the equation if you need to create a table from scratch I'm not sure what you're asking but this will help you fill in a table. Here's and example for this equation.
X Y
1 3
2 6
3 9
Graphs are pretty simple. Just find a value on the x-axis (horizontal), find the point on the line above or below this value, and look at what number it is for the y value. You can do this backwards if you need to find y when given x.
Find angle YWX using the perpendicular or angle bisector method.
Answer:
x = 5
Step-by-step explanation:
9x - 28 = 5x - 8 (because Y and X are equal, and XZ and YZ are equal)
add 8 to both sides
9x - 20 = 5x
subtract 9x from both sides
-20 = -4x
divide 4x from both sides
5 = x
x = 5

Answer:
-457.96
Step-by-step explanation:
Step-by-step explanation:
273.15 + °C = K
°C = K - 273.15
0.95K to °C = 0.95 - 273.15 = -272.2°C
°C to °F
(9/5 °C) + 32 = °F
(9/5 × -272.2) + 32 = °F
-489.96 + 32 = °F
= -457.96°F
