Answer:
1,500 and 300
Step-by-step explanation:
300 x 5 = 1,500
The inverse, f'(x), of f(x) =
X + 5
Х
can be written as
5
x-1
a) Find f(2)
b) Find f'(2)
Step-by-step explanation:
Given
[tex]f(x) = \frac{x + 5}{x} [/tex]
So
[tex]f(2) = \frac{2 + 5}{2} \\ = \frac{7}{2} [/tex]
Now
[tex] {f}^{ - 1} (x) = \frac{5}{x - 1} [/tex]
So
[tex] {f}^{ - 1} (2) = \frac{5}{2 - 1} \\ = \frac{5}{ 1} \\ = 5[/tex]

Answer is x^2-2x-24
Step-by-step explanation:
3sin60°+xcos30°.tan45°=xcot30°
Answer:
x = (6[tex]\sqrt{2}[/tex])/(4[tex]\sqrt{2}[/tex] -3)
Step-by-step explanation:
sin60 degree = [tex]\sqrt{3}[/tex] /2
cos30 degree = 1/2
tan 45 degree = sin45 degree / cos45 degree = ([tex]\sqrt{2}[/tex]/2)/([tex]\sqrt{2}[/tex] /2) = 1
cot 30 degree = cos30 / sin30 = ([tex]\sqrt{3}[/tex] /2)/(1/2) = [tex]\sqrt{3}[/tex]
so, let us plug the above values in the given eqution and solve for x
3([tex]\sqrt{3}[/tex] /2 ) + x(1/2) *1 = x([tex]\sqrt{3}[/tex])
3([tex]\sqrt{3}[/tex] /2 ) = x([tex]\sqrt{3}[/tex]) -x(1/2)
3([tex]\sqrt{3}[/tex] /2 ) = x(([tex]\sqrt{3}[/tex])-(1/2)) (by taking x as a common factor)
3([tex]\sqrt{3}[/tex] /2 ) = x(((2[tex]\sqrt{3}[/tex])-(1))/2)) (making the same common denominator
now devide both sides by (((2[tex]\sqrt{3}[/tex])-(1))/2))
x = 3([tex]\sqrt{3}[/tex] /2 ) / (((2[tex]\sqrt{3}[/tex])-(1))/2))
x = 3([tex]\sqrt{3}[/tex] ) / ((2[tex]\sqrt{3}[/tex])-(1))

17 squared is between which of the following pairs
a. 4 and 5
b.16 and 18
c.288 and 290
d. i dont know
and d is actually a answer i dont know why
NUMBER: 17 SQUARE: 289 SQUARE ROOT: 4.123
Hope this helps a little.
Answer:
a. 4 and 5
Step-by-step explanation:
We are given 17 squared, and are asked on whether which of it is between the following pairs.
Squaring a number always gives it a smaller number since you are trying to find a number times itself to make the number in the square root.
Therefore by this knowledge, a. would be the most reasonable answer, since 17 is quite a small number, squaring it will equal something smaller.
please help me I'm confused
Answer: The correct answer is 8^2 or 64
Step-by-step explanation: Can I please get the brainliest answer.
Answer:
8²
Step-by-step explanation:
When we divide numbers with exponents that have the same bases, we can just subtract the exponents. So, 8^9/8^7 equals 8^(9-7) = 8^2 (Which equals 64, but it isn't a power).
Is 2/5 and 8/20 equivalent
Answer:
Yes, they are.
Step-by-step explanation:
r + 4s = -8
3r + 2s = 6
Answer:
R = 4
s = -3
Step-by-step explanation:
r + 4s = -8
3r + 2s = 6
there are several ways to solve this system but i chose the elimination method and multiplied the second equation by -2 to get:
-6r - 4s = -12 and added it to the first equation
+ 1r + 4s = -8
-5r = -20
r = 4
plug in to find 's': 4 + 4s = -8
4s = -12
s = -3

3. The point P(3,5) is rotated 90° clockwise
about the origin. What are the coordinates of
P'?
A. P'(-3,-5)
B. P’(5,-3)
C. P'(-5,3)
D. P'(5, 3)
Please :)
Answer:
New coordinates of P' are: P'(5, -3)
Hence, option B i.e. P'(5,-3) is correct.
Step-by-step explanation:
When a point A(x, y) is rotated 90° clockwise around the origin, we flip x and y and reverse the sign of x.
Thus,
The rule to rotate a point A(x, y) after a rotation 90° counterclockwise around the origin is:
A(x, y) → A'(y, -x)
In our case, the point P(3, 5) is rotated 90° clockwise about the origin. Thus, the coordinates of P' will be:
A(x, y) → A'(y, -x)
P(3, 5) → P'(5, -3)
Therefore, coordinates of P' are: P'(5, -3)
Hence, option B i.e. P'(5,-3) is correct.

(8x + 9) + (–6x – 1)
Answer:
5
Step-by-step explanation:
Simplifying
(8x + 9) + -1(6x + -1) = 0
Reorder the terms:
(9 + 8x) + -1(6x + -1) = 0
Remove parenthesis around (9 + 8x)
9 + 8x + -1(6x + -1) = 0
Reorder the terms:
9 + 8x + -1(-1 + 6x) = 0
9 + 8x + (-1 * -1 + 6x * -1) = 0
9 + 8x + (1 + -6x) = 0
Reorder the terms:
9 + 1 + 8x + -6x = 0
Combine like terms: 9 + 1 = 10
10 + 8x + -6x = 0
Combine like terms: 8x + -6x = 2x
10 + 2x = 0
Solving
10 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10' to each side of the equation.
10 + -10 + 2x = 0 + -10
Combine like terms: 10 + -10 = 0
0 + 2x = 0 + -10
2x = 0 + -10
Combine like terms: 0 + -10 = -10
2x = -10
Divide each side by '2'.
x = -5
Simplifying
x = -5

Answer:
130°
Step-by-step explanation:
∠JDG and ∠EDF are opposite angles. The measures of arcs for opposite angles always add up to 180°. Since the arc for ∠JDG is 50°, the arc for ∠EDF has to be 130°, because 50 + 130 = 180.

7. (07.03) An equation is shown below: 4(2x - 5) + 15 = 11 Write the steps you will use to solve the equation and explain each step. (5 points)
Answer:
x = 2
Step-by-step explanation:
[tex]4(2x-5)+15 = 11 => 4(2x-5) = 11 - 15 => 4(2x-5) = -4 => 2x-5 = \frac{-4}{4} => 2x-5 = -1 => 2x = -1 + 5 => 2x = 4 => x = 2[/tex]
The value of x is 2 for equation 4(2x - 5) + 15 = 11
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 4(2x - 5) + 15 = 11
Four times of two x minus five plus fifteen equal to eleven
4(2x - 5) + 15 = 11
Apply distributive property on the LHS
8x-20+15=11
8x-5=11
Add 5 on both sides
8x=16
Divide both sides by 8
x=2
Hence, the value of x is 2 for equation 4(2x - 5) + 15 = 11
