Answer:
f(x)=(x+3)^2+5
let f(x)=y
y=(x+3)^2+5
interchanging role of x and y
x=(y+3)²+5
x-5=(y+3)²
√(x-3)-3=y
y=√(x-3)-3
:.inverse of f(x)=(x+3)^2+5 is f-¹(x)=√(x-3)-3
Evaluate: log6 1,296
Answer:
4
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex] then
let [tex]log_{6}[/tex] 1296 = n
1296 = [tex]6^{n}[/tex] = [tex]6^{4}[/tex] , thus
n = 4

STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x, find x and the measure of each side.
Answer:
x = 12Side = 23 unitsStep-by-step explanation:
STU is an equilateral triangle. And:
ST = 2x - 1SU = 5x - 37TU = x + 11All sides are equal. Then take one pair and solve for x:
2x - 1 = 5x - 373x = 36x = 12Substitute x to find the side length:
2x - 1 = 5x - 37 = x + 11 = 23Write 14 more then a number (pre algebra)
Answer:
14>4
Step-by-step explanation:
If we read this it literally says 14 is greater than 4. We always read left to right so if it was 14<4 it would be 14 is less than 4, which we know isn't true but just for an example.
46 decreased by twice the number
-46

Answer:
a) 13.4
Step-by-step explanation:
This will use the pythagorem theorm. Which is a^2 + b^2 = c^2. You'll start with 12^2 + 6^2 = c^2. Then you'll solve from there.
12^2 + 6^2 = c^2
144 + 6^2 = c^2
144 + 36 = c^2
180 = c^2
then you'll find the square root of 180 (i don't have that symbol on my keyboard)
/180 = c
6/5 = c
then in decimal form it's 13.4164...
so rounded it's 13.4
put these numbers in order from least to greatest

Work out the gradient of a line that passes through co-ordinates (3,4) & (6,16).
Answer:
4.33
Step-by-step explanation:
Given data
x1= 3
y1=3
x2=6
y2=16
M= y2-y1/x2-x1
substitute
M=16-3/6-3
M= 13/3
M=4.33
Hence the gradient is 4.33
Lin solved the equation 8(x-3)+7=2x(4-17) incorrectly.
Find the errors in her solution. What should her answer have been?
Lin's Steps - 8 (x-3) + 7 = 2x (4 - 17)
8 (x-3) + 7 = 2x (13)
8x - 24 + 7 = 26x
8x - 17 = 26x
-17 = 34x
-1/2 = x
Answer:
22
Step-by-step explanation:
Answer:
1/2 = x
Step-by-step explanation:
8 (x-3) + 7 = 2x (4 - 17)
8 (x-3) + 7 = 2x (-13)
8x - 24 + 7 = -26x
8x - 17 = -26x
-17 = -34x
1/2 = x

Answer:
m=s+0.50
3m+2s=23.95
Step-by-step explanation:
Answer:
m-s+0.50
3m+2s=23.95
Step-by-step explanation:
the first one is defining m in terms of S
the second is solving
I know they didn't ask but here is the solution:
so in this case you would replace 3m with 3(s+0.50)

What two variables are used most often in 2-variable equations?
Solve for n. -4n + 7 = 1 – 2n
Answer:
n = 3
Step-by-step explanation:
subtract 1 from both sides to get:
-4n + 6 = -2n
then add 4n to both sides to get:
6 = 2n
then divide both sides by 2 to get:
3 = n
Brooke went to the hardware store and bought 20 identical copper pipes. When Brooke lined up the pipes end-to-end, the line was 1 meter long. How long was each pipe?
Answer: 5cm
Step-by-step explanation:
First and foremost, we should note that
1 meter = 100 centimeters
Therefore, since Brooke went to the hardware store and bought 20 identical copper pipes and their total length is 1 meter long which is 100cm, the length of each pipe will be the title length of the Pipe divided by the number of pipes. This will be:
= 100 / 20
= 5cm each.
Each pipe is 5cm long.

D) 7(x+10) and 7x+70
how do you solve these kinds of equations? (3x+5) (3x+5)
Answer:
-5/3
Step-by-step explanation:
(3x+5)(3x+5) is the factored form of the quadratic: 9x^2+30x+25
In equation form, it will be 9x^2+30x+25 = 0 so we have:
(3x+5)(3x+5) = 0
To solve these types of equations, we find the roots. Since the product of these numbers is 0, (3x+5) has to be equal to 0.
3x + 5 = 0
Subtract 5
3x = -5
Divide by 3
x = -5/3

What is the slope intercept ?
Please help me !!
Answer:
y=mx+b
Step-by-step explanation:
Answer:
slope=3, y-intercept=1
Step-by-step explanation:
slope is rise/run, so if you rise 3 and run 1 on the line, you get 4 for the slope, the y intercept is where the line crosses the y-axis, in this situation, it crosses it at (0,1).
