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.
Answers
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

25 + 1-14 +3

Answer:
None of the answers are right the answer is 15
Step-by-step explanation:
25 plus 1 equals 26, and 26 minus 14 equals 12, and 12 plus 3 equals 15, so I don't think that any of the answers are correct.
Answer:
The answer is 15 (none on option)
Step-by-step explanation:
25+1-14+3
= (25+1+3)-14
= (26+3)-14
= 29-14
= 15

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.
Answers
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)

What’s the value for x
Answers
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

Ramona's lemonade pitcher holds 32 ounces of lemonade, but it has a crack and leaks lemonade at a rate of 3 ounces per minute.
What is the rate of change and what does it represent for the situation?
Answers
Answer:
Step-by-step explanation:
The rate of change of the situation is known as the slope:
Slope = Δy/Δx
Slope = y2-y1/x2-x1
From the graph, x2 = 10.5, x1 = 0. y2 = 32, y1 = 0
Slope = 32-0/10.5-0
Slope = 32/10.5
Slope = 3.047
Hence the rate of change is 3.047 ounces per minutes and the situation represents the slope of the graph.
Select all that apply.

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.

Step-by-step explanation:
2.8>2.325
answer: > p l e a s e m a r k b r a i n l e s t .
this is because 2 4/5 = 2.800 and 2.800 is bigger than 2.325 because in the tenths place column (the column closest to the decimal without going over it), 8 is bigger than 3 so 2.800 is bigger than 2.325. So the answer is 2 4/5 > 2.325.

Graph 1 ⇒ Perpendicular
Graph 2 ⇒ Neither
Graph 3 ⇒ Parallel
Graph 4 ⇒ Neither
Step-by-step explanation:
Perpendicular lines: two lines intersected at a point and formed 4 right angles at this point.Parallel lines: two lines move in the same direction and never intersect each other.Let us study each Graph
Graph 1:
∵ There are two intersected lines at a point
∴ They are not parallel
∵ The angles at the point of intersection are right angles
∴ The two lines are perpendicular
Graph 2:
∵ There are two intersected lines at a point
∴ They are not parallel
∵ The angles at the point of intersection are not right angles
∴ The two lines are not perpendicular
∴ The two lines are neither parallel nor perpendicular
Graph 3:
∵ The two lines not intersected at a point
∴ The two lines are not perpendicular
∵ They are in the same direction
∴ The two lines are parallel
Graph 4:
∵ The two lines not intersected at a point
∴ The two lines are not perpendicular
∵ They are NOT moved in the same direction
∴ The two lines are not parallel
∴ The two lines are neither parallel nor perpendicular
