If x = 3 and y = 5, work out the value of a) 4x - 2y
b) 2x2 + 3y2
Answer:
A) 12-10
B)36+225
Step-by-step explanation:
A) 3x4=12, 5x2= 10= 12-10
B) 3x2=6x6=36, 3x5=15x15=225=36+225
For x = 3 and y = 5 the values of the given expressions are (a) 4x - 2y = 2 and (b) 2x² + 3y² = 93.
What is substitution?Substitution is a mathemaical technique for replacing variables with specific or covnient values according to the context.
When the values of variables are given to solve an equation we just have to replace those numerical values in place of the given variables.
Given, x = 3 and y = 5.
∴ 4x - 2y is,
= 4(3) - 2(5).
= 12 - 10.
= 2.
And
2x² + 3y².
= 2(3²) + 3(5²).
= 2(9) + 3(25).
= 18 + 75.
= 93.

Step-by-step explanation:
Alrighty, now if I understood the problem correctly, we can simplify it to:
-5=n-2
We do +2 on both sides, and -5+2 is -3
So, n=-3
Answer:
n= -3
you move the variable to the other side it has to be by it self on the other side of the equal sigh
Step-by-step explanation:

Find the volume of the cylinder. Use 3.14 for pi. Round your answer to the nearest tenth.
Answer:
The formula for the volume of a cylinder is V=Bh (where B is the base) or V=πr2h . The radius of the cylinder is 9 ft and the height is 6 ft. Substitute 9 for r and 6 for h in the formula V=πr2h = (3.14) (9) (2) (6) =339.12
Step-by-step explanation:
Now C=339.12 round to the nearest tenth is 339.1

Answer:
Did you know that Aronson and Carnes-McNaughton's have the perspective on how they study
ancient things from the past.I agree that Aronson will agree with Carnes--McNaughton's statement because they both said the same thing but just in different words. For example in the book "If Stones Could Speak," it will tell what Aronson statement was about when it comes to archaeology and in "Profiles Of Archaeologist," it will tell you the same statement but just in different words. For example it states in the book "If Stones Could Speak," on page 56 "Marc Aronson believes that, “It is about putting aside what you think you know, what has been passed along, and being willing to trust what you yourself see and to test it rigorously.” From this quote the reader will now know what Aronson thinks when it comes to archaeology. In "Profiles Of Archaeologist." On paragraph 19 It states "Being an archaeologist means looking at the world around us in a different perspective. We live in the present as we study the past in order to learn what to do in the future---- on this planet and possibly other. We learn to be humanities while at the same time we practice as scientists. From this quote the reader can understand that both of these statements are similar but they are just reworded. In closing, This why I think that Aronson and Carnes will agree to what to what there statement was.

Answer:
Part 1: At eight hours they both charge the same.
Part 2: Flush Plumbing charges the least
Step-by-step explanation:
Part 1:
Flush Plumbing Co Equation: 50 + 10 h (h = hours)
Fire-in-the-hole Plumbing: 90 + 5h (h = hours)
50 + 10h = 90 + 5h
Solve the Equation:
5h = 40
h = 8
Part 2:
Plug in 7:
Flush Plumbing: 50 + 10 x 7 = 50 + 70 = $120
Fire-in-the-hole Plumbing: 90 +5 x 7 = 90 +35 = $125
Flush plumbing chargers the least

Help please
Answer:
x = 1 or -5/2
Step-by-step explanation:
-2x^2 - 3x + 5 = 0
multiply all through by -1
2x^2 + 3x - 5 = 0
....... 2x^2 × 5 = 10x^2 = +5x × -2x
(2x^2 + 5x)-(2x - 5) = 0
x(2x + 5) - 1(2x + 5) = 0
x - 1 = 0 or 2x + 5 = 0
x = 1 or 2x = - 5
x = 1 or -5/2

Suppose there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 58.3°F, what will be the temperature when the plane reaches an altitude of 2,000 ft?
Answer: 55.1°F
Step-by-step explanation:
We are informed that there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky, if the plane reaches an altitude of 2,000ft, the drop in temperature will be:
= 1.6° × 2
= 3.2°F
If the temperature on the ground is 58.3°F, then the temperature when the plane reaches an altitude of 2,000 ft will be:
= 58.3°F - 3.2°F
= 55.1°F
-3 is a zero for the polynomial:
x^3 + 7x^2 + 16 x + 12
True or False
Answer:
true
Step-by-step explanation:
If x = - 3 is a zero of the polynomial then f(- 3) = 0
f(x) = x³ + 7x² + 16x + 12
= (- 3)³ + 7(- 3)² + 16(- 3) + 12
= - 27 + 63 - 48 + 12
= 0
Since f(- 3) = 0 then x = - 3 is a zero of the polynomial

Which angles are corresponding angles?
Check all that apply.
The corresponding angles are
2 and 6
3 and 7
5 and 3
and, 4 and 8
What are corresponding angles?
Any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal are called corresponding angles.
Or, when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.
According to the given question.
We have a diagram, in which there are two parallel lines and one another line which is intersecting these two lines.
From the given diagram,
The pairs of angles 2 and 6, 1 and 5, 3 and 7, and 4 and 8 are occupying the same relative positions, upper right side, upper left side, lower left side, and lower right side respectively.
Therefore, we can say that angles
2 and 6
3 and 7
5 and 3
and, 4 and 8
are corresponding angles.

We can draw the line y = 1 and reflect the triangle XYZ over it.
A video rental store charges a $20 membership fee and $2.50 for each video rented.
Write a linear equation to model this situation.
Tell what each variable represents.
Answer:
2.5x + 20 = y
Step-by-step explanation:
first, assign a variable to each unknown:
since we don't know how many videos were rented, that can be x, and we don't know the person's total cost, which can be y
x = number of videos rented
y = total cost
so there's always a $20 that's added on as a membership fee, which means that theres going to be a + 20 somewhere.
So, the equation is 2.5x + 20 = y
