4. Two times a number added to another number is 25. Three times the first number minus the other number is 20. Find the two numbers.
Answer:9 & 7
Step-by-step explanation:
Let x be the first number and y be the second.
2x + y = 25
3x - y =20
1) Add them together.
5x = 45
x = 9
2) Solve for y.
2(9) + y = 25
y=7
3) Check your work on the other equation.
3(9) - (7) = 20
27 - 7 =20
20 = 20

I Need A Expert To Answer This! Find The Measure Of The indicated Angle In The Diagram.
Answer:
So,you're answer will be 21°{degree}..
Answer:
m∠YPQ = 159°
Step-by-step explanation:
m∠QRP = 107
m∠RQP = 52
m∠RPQ = x
m∠QRP + m∠RQP + m∠RPQ = 180°
107 + 52 + x = 180
159 + x = 180
x = 21°
m∠RPQ = x = 21°
m∠RPQ + m∠YPQ = 180°
21° + m∠YPQ = 180°
m∠YPQ = 159°

Sound intensity, in decibels, d, can be written using a comparison factor, x, that compares sound intensity to the standard threshold of hearing. d = 10log(x) A sensor measures the sound intensity, in decibels, of an office over time. The decibel reading was consistently above 50, but never above 70. On what interval is the factor by which the office noise is related to the standard threshold of hearing? (17, 18.5) (17, 18.5] (100,000, 10,000,000] (100,000, 10,000,000)
Answer: (100,000, 10,000,000]
Step-by-step explanation:
The interval is given by ( 100,000 , 10,000,000], the correct option is C.
What is the Threshold Value ?The threshold value is the minimum value above which the desired results can be expected.
The decibel reading was consistently above 50, but never above 70.
d = 10log(x)
50 = 10log(x)
5 = log x
10⁵ = x
x > 10⁵
d = 10log(x)
70 = 10log(x)
x = 10⁷
From the given data
x ≤ 10⁷
Therefore, the interval is given by ( 100,000 , 10,000,000], the correct option is C.

Step-by-step explanation:
The Linear function has one independent and one dependent variable. The value of dependent variable can be found by taking the equation equals to 0. The domain function is set to analyse the range. The range can be set as -1 to 1. Any number between this is acceptable but outside this is not considered in the domain.

What’s the value for x
Answer:
5 = x
Step-by-step explanation:
5 divided by 2 = 2.5
12.5 divided by 2.5 = x = 5
Answer:
x= 5
Step-by-step explanation:
As Figure A is a scale image of B. It means that the measurments of A are just multiplied by an integer to get the measurements of B.
2 times 2.5= 5
or
5/2= 2.5
Then, knowing the integer we multiply to get from m< A to m<B is 2.5, we DIVIDE
12.5/ 2.5 to get "x" which is 5

Which statements correctly describe the graph of the function f(x) = x3 – 4x2 – 3x + 18? Select three options.
There are three unique solutions to the function when y=0.
The function has a double root.
As x increases from negative infinity to positive infinity, the y-values increase, decrease, and then increase again.
As x approaches negative infinity, y approaches positive infinity.
The domain and range of the function are the set of real numbers.
Answer:
(B) The function has a domain of all real numbers.
(C) The function has a range of {y|–Infinity < y < Infinity}.
(E) The function passes through the point (3, –27).
Step-by-step explanation:
The statements are true.
What is faction?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
The given function is:
f(x) = x³- 4x² - 3x + 18
After plotting its graph can see the graph of the function.
The statements that are true are:
As x increases from negative infinity to positive infinity, the y-values increase, decrease, and then increase again.
You can see this in the graph and may be really hard to see it without the graph, the easier way would be to see the derivate of f(x) and see that is first positive, then negative, and then positive.
f'(x) = 3x² - 8x - 3
As the leading coefficient is positive, the arms open up, and f'(0) = -3
Then is easy to see that from left to right, is positive, then negative, and then positive again.
The domain and range of the function are the set of real numbers.
For the domain, we do not have any denominator nor weird function that has problems in a particular value, so the domain is the set of all real numbers.
And as you can see, as the leading coefficient is an odd power of x, the range will go from minus infinity to infinity (you can also see it in the graph).
The function has a double root.
Yes, in the graph you can see two roots, but this is a 3rd-degree polynomial, so it must have 3 roots, this means that one of the roots in the graph is a double root. (Where the double root is at x = 3, as you can see in the graph)
