Find function inverse of f? F(x)=x+2/7
Answers
Answer:
f’(x) = x -2/7
Step-by-step explanation:
Let f(x)= y
Thus;
y = x + 2/7
x = y-2/7
So the inverse f’(x) = x - 2/7
The length of a rectangle is 3x-4 and the width is x. The perimeter is 72 feet. What is the measure of the length?
Answers
First, you would have to set an equation to find the value of x. To find this equation you would multiply both expressions for length and width by two. You would get the expression (6x-8) for length and the expression (2x) for width. You would then add these and make them equal to the perimeter, 72. You would get the equation 8x-8=72. Solving this equation would give you x=10. You just plug this value of x into the expression for length, which gives you the answer 26 ft.
Answer:
26 is your answer. I hope this helps!

A ladder 50 dm long when set against the wall of a house just reaches a window at a height of 48 dm. How far is the lower end of the ladder from the base of the wall?
Answers
Answer:
14dm
Step-by-step explanation:
To solve this question we can use the Pythogorean theorem
a^2 + b^2 = c^2
In this case, The ladder is the hypotenuse, the height is one of the leg of the right angle triangle
Let's keep the missing side as x
If we apply the theorem,
x^2 + 48^2 = 50^2
x^2 + 2304 = 2500
x^2 = 2500 - 2304
x^2 = 196
[tex]x = \sqrt{196} \\ x = 14[/tex]

A bag contains cards numbered from 1 to 14 one card is drawn at random find the probability of
a.) Selecting a prime number of a multiple of four
b.) selecting a multiple of two or a multiple of three
Answers
Answer:
One: P = 1/2 = 0.5
Two: P = 8/14 = 4/7 = 0.714
Step-by-step explanation:
One
I take it that the question is a prime number or 4.
P(four) = 1/14
The primes are 2,3,5,7,11,13. There are 6 of them
P(prime) = 6/14
P(prime or four) = 6/14 + 1/14 = 7/14 = 1/2
Two
Multiple of 2 := 2 4 6 8 10 12 14
Multiple of 3 := 9 in addition to 6 and 12 which cannot be counted twice.
P(2 or 3) = 8/14 = 4/7 = 0.714

(7,-1) and (9,0)
Answers
Answer:
1/2 or 0.5 (same value, different form)
Step-by-step explanation:
Ok...since I can't actually graph it, we can make a table out of it....
x y
7 -1
9 0
From -1 to 0, we add 1 (this is for the y section)
From 7 to 9, we add 2 (this is for the x section)
Now all we have to do is divide the y with the x
y/x = 1/2
The slope will be 1/2 (fraction form) 0.5 (decimal form)

On Thursday, a local hamburger shop sold a combined total of 417 hamburgers and cheeseburgers. The
number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were
sold on Thursday?
Answers
Let H represent Hamburgers.
Let cheeseburgers represent 2H .
H + 2H = 417
3H = 417
H = 417/3
H = 139 hamburgers
2H = 2 * 139 = 278 cheeseburgers
Therefore, there were 139 hamburgers sold on Thursday.

z's exponent = 5
Step-by-step explanation:
the degree of monomial is basically all of the exponents added up
so:
x's exponent + y's exponent + z's exponents = the degree
So:
1+2+z's exponent = 8
(since x to the power of 1 = x)
3+z's exponent = 8
Subtract 3 from each side:
z's exponent = 5
8.

Point of Intersection:
Answers
Answer: (0; - 1)
Step-by-step explanation:
y = 5x - 1 and 5x = - 1 - y
y = - 1 - 5x
5x - 1 = - 1 - 5x
5x = -5x
5x + 5x = -5x + 5x
10x = 0
x = 0
y = 5x - 1
y = 5 × 0 - 1 = - 1
