Step-by-step explanation:
The value of AZ will be 40.
A is a point between Y and Z and YA = 14x , AZ = 10x and YZ = 12x + 48.
We have to calculate the value of AZ.
What is the value of MP , if N is the midpoint of M and P ?
The value of MP will be equal to the summation of NM and NP i.e., MP = NP + NM .
As per the question ;
A is the midpoint of Y and Z.
⇒ AZ + YA = YZ
⇒ 10x + 14x = 12x + 48
⇒ 24x = 12 x + 48
⇒ 12x = 48
⇒ x = 4
So ,
The value of AZ will be ;
AZ = 10 × 4
AZ = 40
Thus , the value of AZ will be 40.

Answer: 40 peaches
Step-by-step explanation:
Let x represent (1/2) the peaches
and y represent (1/2) the strawberries
Peaches Strawberries Ratio
Alice: x - 3 y 1:4
Bryan: x y - 8 1:3
We can create a system of equations:
Alice: 4(x - 3) = y --> 4x - 12 = y
Bryan: 3(x) = y - 8
Substitute y = 4x - 12 into the Bryan equation:
3x = (4x - 12) - 8
3x = 4x - 20
-x = -20
x = 20
Therefore, Alice and Bryan each had 20 peaches, which means Bryan bought a total of 40 peaches.

What is (6x10^6)(4x10^-1) ?
Answer:
Step-by-step explanation:
Multiply the 6 and 4 together. 6*4 = 24
The next part is a bit tricky. Add the powers on the base 10. Keep the base 10.
10^(6 - 1) = 10^5
Now put the two parts together. 24 * 10^5
The number in front of the 10 must be between 1 and 10.
So 24 can be written as 24 = 2.4 * 10^1
2.4 * 10^1 * 10^5 = 2.4 * 10^(5 + 1) = 2.4 * 10^6

In other words, describe the set or points (x, y, z) such that y = 2 and z = 8. a) a line.b) a circle.c) a plane.d) a point.
Answer:
The equation [tex]x=4[/tex] represents in R^2 c) a line
The equation [tex]x=4[/tex] represents in R^3 a) a plane
The equation [tex]y+3x=2[/tex] represents in R^3 a) a plane
The equation [tex]z-4y=8[/tex] represents d) a plane
The pair of equations [tex]y=2,z=8[/tex] represents a) a line
Step-by-step explanation:
Let's start by studying each question :
1)
In R^2 , [tex]x=a[/tex] with [tex]a[/tex] ∈ IR is the equation of all vertical lines
In this case, the only free variable is the variable ''y''
R^2 has two dimensions (x and y) so if we set [tex]x=4[/tex] we will have only one free variable in R^2 (which is a line in R^2). Therefore, [tex]x=4[/tex] represents a line in R^2
Now, in R^3 we have three dimensions (x, y and z) so if we set [tex]x=4[/tex] we will have only two free variables (y and z) and [tex]x=4[/tex] will represent a plane (which have two dimensions) in R^3.
2) The equation [tex]y+3x=2[/tex] in R^3 has the free variable ''z'' and given that we select a value (for example for ''x'') the another value from the variable ''y'' is determined. Finally, we have the free variables ''z'' and ''x'', and the variable ''y'' restricted for our choice of the variable ''x''.
The equation [tex]y+3x=2[/tex] in R^3 (given that we have two free variables) represents a plane.
Using the same reasoning, the equation [tex]z-4y=8[/tex] represents a plane (given that it has two free variables : ''y'' and ''x'')
Finally, the pair of equations [tex]y=2,z=8[/tex] set values for ''y'' and ''z'' leading us ''x'' as the free variable. With only one free variable we will have a ''one dimensional'' geometric form. The one dimensional forms in R^3 are lines.
The final answer is a) a line.

Beth is solving this equation: 1/x+3=3/x
She says “I can multiply both sides by x and get the linear equation 1 + 3x = 3, whose solution is x = 2/3.”
Which of the following statements makes this a correct argument, or shows that it is incorrect? Select all that apply.
Question 1 options:
After multiplying both sides by x you need to subtract 1 from both sides
You can assume x ≠ 0 because both sides are undefined if x = 0.
You cannot multiply both sides by x because you do not know what x is.
The equation is not linear, so you cannot use the methods normally used for solving linear equations.
Answer:
1. After multiplying both sides by x you need to subtract 1 from both sides
2. You can assume x ≠ 0 because both sides are undefined if x = 0.
Step-by-step explanation:
Given
[tex]\frac{1}{x} + 3 = \frac{3}{x}[/tex]
Required
Which of the options shows the validity of Beth's action
The first option answers the question and the reason is as follows;
Multiply both sides by x
[tex]x * (\frac{1}{x} + 3) = \frac{3}{x} * x[/tex]
Open the bracket
[tex]1 + 3x = 3[/tex]
As stated in option 1; Subtract 1 from both sides
[tex]1 - 1 + 3x = 3 - 1[/tex]
[tex]3x = 2[/tex]
Divide both sides by 2
[tex]x = \frac{2}{3}[/tex]
Another correct option is the option 2
Because the expression is undefined if x = 0
See Proof by substituting 0 for x
[tex]\frac{1}{0} + 3 = \frac{3}{0}[/tex]
Division by 0 is undefined.
Hence, option 2 is also correct
The other options (3 and 4) are incorrect

A. X = -15
B. X =-12
C. X = 12
D. X = 15

George weighs 60 pounds less than his older brother. Together they weigh 240 pounds. How many pounds does George weigh?
Easy Algebra question!
Let's use "x" as a variable.
The equation would be x+x+60 = 240 with "x" being George's weight.
Subtract 60 from both sides and you get 2x = 180.
From there you divide both sides by 2, getting x=90.
"x" is George's weight, so he weighs 90 pounds.
ANSWER: 90 POUNDS
The weight of George is 90 pounds and the weight of George's brother is 150 pounds.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
George weighs 60 pounds less than his older brother.
Together they weigh 240 pounds.
Let George weigh be x and his brother weigh be y.
x + y = 240 ...1
x = y - 60 ...2
Then from equations 1 and 2, we have
2x = 180
x = 90
Then y will be
y = 90 + 60
y = 150

Answer:
First problem:
Limiting the Domain to [tex]x\leq 0[/tex] (option A in the list)
Second problem:
All the three statements are true, so pick option D)
Step-by-step explanation:
Recall that a function in order to have inverse needs to be a one-to-one function. In the case of the function they give you in the problem:
[tex]f(x)= 3x^2+1[/tex]
the graph corresponds to a parabola with vertex at x=0 and y=1 (0, 1), and since it has two branches that correspond to equal y-values for opposite pairs of x values, it doesn't satisfy the conditions for the existence of inverse. But if we limit the Domain of it considering just one half of the graph (for example limiting the Domain to the values to one side of the parabola's vertex, then this restricted function is one-to-one and we can find its inverse.
So the option of limiting the Domain to x-values smaller than or equal to zero, suggested in option A of the list of answers will do the job we need.
In the following problem, the three first statements are true for an inverse function, so pick option D that says that all previous statements are true.

In a geometric sequence, the 5th term is 9 and the 7th term is 36. Use the geometric
mean to find the 6th term.
Answer:
18
Step-by-step explanation:
you need to get from 9 to 36 in 2 steps by multiplying, so you need to find what gets 9 to 26 in one turn. 9*4=36, and because 4 is square we know you can multiply by 2 twice to get the same effect. 9*2=18. and just to make sure we can check that 18*2=36
-35x+85x-24=26 what is x
Answer:
x=1
Step-by-step explanation:
-35x+85x-24=26
Combine like terms
50x -24 = 26
Add 24 to each side
50x-24+24 =26+24
50x = 50
Divide each side by 50
50x/50 = 50/50
x=1
Answer:
x=1
Step-by-step explanation:
subtract 35 from 85 which would equal 50 and then add x
so 50x-24=26
add 24 to 26 because you want x by itself
which would equal 50
50x=50
divide by 50 on both sides
50/50=1
x=1
