Answer:
x= 8.5, 2x=17, (9x+5)=81.5
Step-by-step explanation:
since the sum of the interior angles of a triangle is 180 degrees, you must add all of the angles and set them equal 180:
[tex]2x + 2(9x+5) = 180[/tex]
next distribute the 2 to 9x + 5.
[tex]2x + 18x + 10 = 180[/tex]
next combine like terms (2x and 18x) and subtract 10 from 180.
[tex]20x = 170[/tex]
finally, divide 170 by twenty.
[tex]\frac{20x = 170}{20}\\,x=8.5[/tex]
the final answer is x=8.5
once x is determined, you can solve 2x and 9x+5.
[tex]2(8.5)=17\\\\9(8.5) +5 =81.5[/tex]

Find f^-1(x) where
f(x) = 3x+2/x
Given:
Consider the function is
[tex]f(x)=\dfrac{3x+2}{x}[/tex]
To find:
The inverse of the function, .i.e., [tex]f^{-1}(x)[/tex].
Solution:
We have,
[tex]f(x)=\dfrac{3x+2}{x}[/tex]
Putting f(x)=y, we get
[tex]x=\dfrac{3y+2}{y}[/tex]
Isolate the variable y.
[tex]xy=3y+2[/tex]
[tex]xy-3y=2[/tex]
[tex]y(x-3)=2[/tex]
[tex]y=\dfrac{2}{x-3}[/tex]
Putting [tex]y=f^{-1}(x)[/tex], we get
[tex]f^{-1}(x)=\dfrac{2}{x-3}[/tex]
Therefore, the inverse function is [tex]f^{-1}(x)=\dfrac{2}{x-3}[/tex].
A car moving on a highway covers the first 400.0 m in 18.0s and then covers the next 250.0 m in 24.0 s.
What is the average speed of the car?
Answer: 15.48 m/s
Step-by-step explanation:
The following information can be gotten from the question:
Total distance covered by the car will be:
= 400m + 250m
= 650m
Total time taken = 18.0s + 24.0s = 42s
Average speed = Distance/Time
= 650/42
= 15.48 m/s

Answer:
1. 45
2. 105
3. 95
4. 85
Step-by-step explanation:
For problems 1 and 4:
Consecutive angles are supplementary in a parallelogram, which means they equal 180.
180 - 135 = 45
180 - 95 = 85
For problems 2 and 3:
Opposite angles are congruent or equal each other in a parallelogram,

The value of the function at x = -3 is -1
What is function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range.
Given that a graph of y= f(x), we need to find f(-3)
The graph tells the value of y when x = -3 is -1
Hence, The value of the function at x = -3 is -1

This triangle has one side that lies on an extended line segment. Based on this triangle, what statement about x is true? A. x = 27 because 180−109−44=27 B. x = 65 because 109−44=65 and 44 + 65 = 109 C. x = 71 because 180−109=71 D. x = 153 because 109 + 44 = 153 and 153−44=109
MEASUREMENTS (down below)
A triangle with base on an extended line. Two angle measures are given. Top interior angle is forty-four degrees. Lower right exterior angle is one hundred nine degrees. Lower left interior angle is labeled x degrees.
Answer:
B. x = 65 because 109−44=65 and 44 + 65 = 109
Step-by-step explanation:
Given :
The triangle below :
Sum of interior angles of a triangle :
(44° + x + (180 - 109) = 180°
44° + x + 71° = 180
115° + x = 180°
x = 180° - 115°
x = 65°

Plz give me ans.
When.
....
Answer:
Step-by-step explanation:
Length : Breadth : height = 3 : 4 : 6
Length = 3x
Breadth = 4x
Height = 6x
Volume of cuboid = 576 sq.cm
length * breadth * height = 576
3x * 4x * 6x = 576
72x³ = 576
x³ = 576/72
x³ = 8
x³ = 2³
x = 2
Length = 3*2 = 6 cm
Breadth = 4* 2 = 8 cm
Height = 6*2 = 12 cm
Total surface area = 2*(lb + bh + hl)
= 2 * (6*8 + 8*12 + 12*6)
= 2 * (48 + 96 + 72)
= 2 * 216
= 432 sq.cm

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 3)(0,3) and (4, 7203)(4,7203).
Answer:
[tex]y = 3(7)^x[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (0,3)[/tex]
[tex](x_2,y_2) = (4,7203)[/tex]
Required
Determine an exponential function
Substitute 0 for x and 3 for y in [tex]y=ab^x[/tex]
[tex]3 = ab^0[/tex]
[tex]3 = a*1[/tex]
[tex]3 = a[/tex]
[tex]a = 3[/tex]
Substitute 4 for x and 7203 for y in [tex]y=ab^x[/tex]
[tex]7203= ab^4[/tex]
Substitute 3 for a
[tex]7203= 3*b^4[/tex]
Divide both sides by 3
[tex]2401= b^4[/tex]
Take 4th root of both sides
[tex]\sqrt[4]{2401} = b[/tex]
[tex]7 = b[/tex]
[tex]b = 7[/tex]
Substitute 3 for a and 7 for b in [tex]y=ab^x[/tex]
[tex]y = 3(7)^x[/tex]
