Answer:
x = 5
Step-by-step explanation:
The sum of the angles of a triangle is 180°.
(180 - 18x + 5) + (-1 + 8x) + 46 = 180
⇒ 180 - 18x + 5 - 1 + 8x + 46 = 180
⇒ -10x + 230 = 180
⇒ -10x = -50
⇒ x = 5

measure 1 and measure 2 are supplementary. if measure 1 equals (3x - 17) degrees in measure angle two equals (5x + 21) degrees find the value of x
Answers
Answer:
x = 23 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees. Thus, 3x - 17 degrees plus al 5x + 21 deg must equal 180 degrees.
Combining like terms, we get 8x - 4 = 180, or 8x = 184.
Dividing both sides by 8 yields x = 184/8 = 23 = x (measured in degrees)

How would you write y = 2x - 3 in function notation? *
Answers
Answer:
f(x)=2x-3
Step-by-step explanation:
To write an equation in function notation change the y to an f(x). Then, if you plug something in for x also replace it in f(x). For example, if x=3 then the equation would be f(3)=2(3)-3.
Area of the rectangle is given by the polynomial function A(x)=2x^2+18x. If the width of the rectangle is 2x what is the length?
Answers
The length of the rectangle is x + 9 whose width is gives as 2x.
To find the length of the rectangle, we need to express it in terms of the width.
Given:
width of the rectangle is 2x.
The formula for the area of a rectangle is
A = length × width.
As, the polynomial function for the area:
[tex]A(x) = 2x^2 + 18x[/tex]
So, set up the equation:
[tex]2x^2 + 18x =[/tex] [tex]{\text} width x length[/tex]
Substituting the given width = 2x in above equation gives
[tex]2x^2 + 18x = 2x * length[/tex]
Dividing both sides of the equation by 2x:
x + 9 = length
Therefore, the length of the rectangle is x + 9.

[tex]g(x) = 3^{2x} - 3^x[/tex]
[tex]h(x) = f(x) - g(x)[/tex]

Answers
The answer is A. 42
Solution:
Let x= ones digit, y=tens digit
1st condition (original number) : 7(x+y)=10y + x
2nd condition (new number by reversing the digits): 18+x+y=10x+y
simplifying:
1st condition: 6x=3y
2nd condition: x=2
