Answer:
21°
Step-by-step explanation:
Since these are both equivalent right triangles, ∡RQY and ∡PQY are the same. So set them equal to each other.
16x-27=5x+6
x=3
Next plug x into ∡RQY
16(3)-27=21°

A wise man once said, "300 reduced by 3
times my age is 84." What is his age?
A) 72 B) 48
C) 68 D) 61
Answer:
72
Step-by-step explanation:
Let the man's age be x
300 - 3x = 84
300 - 84 = 3x
216 = 3x
x = 216/3
x = 72
Answer:
A
Step-by-step explanation: cuz 300-72x3=84

Answer:
m<A = 120°
m<C = 45°
Step-by-step explanation:
We can use the triangle sum theorem to find the measures of the angles.
m<A + m<B + m<C = 180°
Then substitute in their given values.
12x + 12 + 15 + 3x + 18 = 180°
Now simplify the equation and you get
15x + 45 = 180°
Continue to solve
15x = 135
x = 9°
Now substitute this value of 9 for the angle expressions of <A and <C
(12 x 9) +12 = m<A
m<A = 120°
(3 x 9)+ 18 = m<C
m<C = 45°
Hope this helps. To check your answer you can add up all the answers to see if it equals 180°.
Consider the polynomial 9x2 – 16.
What is the value of ac?
What is the value of b?
What two numbers multiply to get ac and add to get b?
The factored form of 9x2 – 16 is
Step-by-step explanation:
The value of ac together is 16(9x^2) or 144x^2
The value of B is zero since there is no B
(b is x, ( note not x^2, but only 1x)
Answer:
What is the value of ac? -144
What is the value of b? 0
What two numbers multiply to get ac and add to get b? -12 and 12
The factored form of 9x² - 16 is (3x-4)(3x+4)

Which function represents exponential growth?
a. f(x) = 3x
b. f(x) = x3
c. f(x) = x + 3
d. f(x) = 3x
FIRST PERSON TO ANSWER IS THE BRAINLIEST!!!!
PLEASE GIVE EXPLANATION OF HOW!!
Answer:
Either A or D, but the answer is [tex]f(x) = 3^x[/tex].
Step-by-step explanation:
We can check for exponential growth by checking for an [tex]x[/tex] in the exponent of a constant value in the function, which is this case for [tex]f(x) = 3^x[/tex].
f(x) = x + 3 function represents exponential growth. So the correct option is option is c.
An exponential function is a arithmetic function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is know the base of the function and it will be greater than 0.
An exponential function is explain by the formula f(x) = ax, where the input variable x take place as an exponent.
The exponential curve turn on the exponential function and it depends on the value of the x.
The exponential function is an main arithmetic function which is of the form
f(x) = ax
Exponential Growth
In Exponential Growth, the quantity grow very slowly at first, and then quickly. The rate of change growth over time. The rate of growth becomes faster as time passes. The quick growth is meant to be an “exponential increase”. The formula to explain the exponential growth is:
y = a ( 1+ r )x
Where r is the growth percentage.
Therefore, f(x) = x + 3 is a function represents exponential growth.

What is the sign of f on the interval?
The function f(x) will be sometimes positive and sometimes negative on the interval
Option (3) is correct.
What is a function?An arrangement known as a function connects inputs to essentially one output.
In other words, a function is a relationship between variables, and the nature of that relationship—for example, y = sinx and y = x +6—defines the function.
Given function:
f(x) = (x - 5) (2x - 7) (7x - 3)
The term (x - 5) will be negative if x < 5.
The term (2x - 7) will be negative if x<3.5
So, If x = 4, (x - 5) will be negative but (2x - 7) will be positive, resulting in a negative overall value.
Therefore, if x = 3, then (x - 5) will be negative, as well as (2x - 7), making the whole value negative.
Hence, the function f is sometimes positive and sometimes negative on the interval.

Et of y=x2-4 and + y + 2 = 0?
The equation y = x2 – 4 + y + 2 = 0 can be solved by completing the square.
What is equation?An equation is a mathematical statement that to express our equal. Is consist of two expression separated by an equal sign and can contain numbers, variables and operators. Equation get be used to solve problems make prediction and describe relationship between different quantities. Equation can be can also be used to represent physical laws and other phenomena.
First, subtract y from both sides of the equation to get x2 - 4 + 2 = y. Then, subtract 2 from both sides of the equation to get x2 - 6 = y. Finally, add 9/4 to both sides of the equation to get (x - 3/2)2 = 9/4 + y.
This equation can be solved by taking the square root of both sides to get x - 3/2 = ±√(9/4 + y). Finally, add 3/2 to both sides of the equation to get x = 3/2 ±√(9/4 + y).

Answer:
< F would be 140 degrees
Step-by-step explanation:
So what you would do is that since they told you angle D is 40 degrees and you know that the 2 lines in there are parallel, and since they are asking for angle F, whne you add angle F and angle H they should equal 180 degrees which you know so you just subtract 40 degrees from 180 and you get 140 degrees which if angle F and you can subtract 40 since angle H and angle D would be congruent.

Answer:
24
Step-by-step explanation:
9 can be broken down to 3 because 3 x 3 = 9
15 can be broken down to 3 also because 3 x 5 = 15
> 9 + 15
= 3 ( 3 ) + 3 ( 5 )
= 3 ( 3 + 5 )
= 3 ( 8 )
