Answer:
The formula is [tex]x=\frac{y+pq}{2}[/tex]
Step-by-step explanation:
Given formula is
y = 2x - pq
Adding pq on both sides
y+pq = 2x - pq + pq
y+pq = 2x
2x = y+pq
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{y+pq}{2}\\\\x=\frac{y+pq}{2}[/tex]
I have two question I NEEDS HELP
1# Jason is participating in a walkathon. He writes the equation m = 2d + 50 to represent the amount of money he collects from each sponsor for walking d kilometers. What number represents the rate of change?
2# Cierra is keeping track of the amount of money in her lunch account each week. She writes the equation A = -6w + 40. What number represents the rate of change?
Answer:
The rate of change is the slope
In this case
m=2d+50 is a slope intercept equation.
where m is where the y would be
the 2 which is originally where the slope or (m) would be
the d for the (x)
and 50 for the y intercpet or (b)
so
#1=2
The expalantion is the same but different numbers, when asked for the rate of change look at the slope or the number next to the variable. Also put it in y=mx+b form to make sure the number is correct.
#2= -6
Identify the quadratic function that contains the points (-1,-4), (0,0) and (2,-10).
f(x) = 3x^2 - x
f(x) = 3x^2+x
f(x) = - 3x^2+x
f(x) =-3x^2-x
9514 1404 393
Answer:
(c) f(x) = -3x^2 +x
Step-by-step explanation:
Points either side of (0, 0) have lower y-values, so you know the parabola opens downward. This eliminates the first two choices.
Trying one of the other points in the one of the remaining equations tells you which equation works.
For example, usint (-1, -4) in the third choice, we get ...
f(-1) = -3(-1)^2 +(-1) = -3 -1 = -4 . . . . . matches point (-1, -4)
The correct function is the third choice:
f(x) = -3x^2 +x

Which of the coordinate points below will fall on a line where the constant of proportionality is 1/3? Select all that apply.
A) (5,8)
B) (3,1)
C) (9,3)
D) (12,4)
E) (18,6)
Answer:
The answer is B,C,D and E
The points that show the proportionality rate 1/3 are (3, 1), (9, 3), (12, 4) and (18, 6).
What is proportional relationship?A proportional relationship is a relationship between two expressions and where changes in one expression means some constant change in the other expression as well. Generally, it is represented as x/y = k, where x and y are two expressions and k is constant.
We have constant of proportionality is 1/3.
And the proportionality is represented as x/y = k, where x and y are two expressions and k is constant.
So, x / y = 1/3
A) (5,8)
x/y = 5/8 ≠ 1/3
B) (3,1)
x/y = 1/3
C) (9,3)
x/y = 3/9 = 1/3
D) (12,4)
x/y = 4/12 = 1/3
E) (18,6)
x/y = 6/18 = 1/3
Therefore, B, C, D and E are the answers.

On Monday, the coldest temperature outside was 2 degrees Fahrenheit. On Tuesday, Ms. Perkins tells her students that the coldest temperature outside has an absolute value of 4 degrees.
Rachel says that Tuesday’s coldest temperature could be greater than Monday’s coldest temperature.
Tom says that Tuesday’s coldest temperature could be less than Monday’s coldest temperature.
State whether each student’s statement is true or false, and justify your answers.
PLS I NEED THIS ITS ALL MY POINTS DONT TROLL
ALSO EXPLAIN IT
Answer:
Temperature on Monday was 2 degrees Fahrenheit.
Temperature on Tuesday was absolute value of 4 degrees Fahrenheit.
Absolute value is always a positive number but the actual temperature could have been positive or negative 4 degrees.
| ± 4 | = 4If it was positive, then Rachel is correct, but if negative, then Tom is correct.

A direct variation equation is graphed. The point (6, 4) is on the graph. Which of the following points are also on the
graph of the equation?
(3,2)
(-9,-6)
(-12,8)
(-6,-3)
It is everyone of those except for (-6, 3).
Step-by-step explanation:
4 / 6 = 2/3
2/3 x -9 = -6
2/3 x -12 = -8
2/3 x 3 = 2
2/3 x -6 = -4
why this worked. Think about what we did, play around with some numbers, try to visualize it.
******HINT: If you have anything you can use to SHOW why it worked, try that. I recommend M&M's or a candy that has color. I suggest showing your number, and whats done to it in one color... 10 and what happens to that in another.*******
Think of a number 1-10
Double it
Add 10 to that number
Divide it by 2
Subtract your original number
Your answer is 5
Answer:
10 divided by 2 equals 5 and your original number added then subtracted would be 0, so 0 + 5 equals 5

Question:Determine if the two triangles are congruent. If they are, state how you know.
Answer: If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
Step-by-step explanation: So we know that two triangles are congruent if all of their sides are the same-- so side, side, side. We also know they are congruent if we have a side and then an angle between the sides and then another side that is congruent-- so side, angle, side.

Find f(-3) for f(x) = 4(2)^x
Please answer this as fast as you can need it for today
Answer: [tex]f(-3)=\dfrac12[/tex]
Step-by-step explanation:
Given: [tex]f(x)=4(2)^x[/tex], which is an exponential growth function.
To evaluate: f(-3)
Substitute x=-3 in the given function, we get
[tex]f(-3)=4(2)^{-3}\\\\=4(\dfrac{1}{2})^3\ [a^{-n}=\dfrac1{a^n}]\\\\=4\times\dfrac1{2^3}\\\\=4\times\dfrac18\\\\=\dfrac12[/tex]
Therefore, the value of [tex]f(-3)=\dfrac12[/tex].

The estimated solution is N = 12.
Step-by-step explanation:
1) Round the equation to [tex]N - 6 = 6[/tex].
2) Get the N on one side, and the values on the other side. To do this, add 6 to both sides. You end up with [tex]N = 12[/tex].
3) N = 12 is therefore the answer.

help please, im unsure
Answer:
The value of AM = 43
Step-by-step explanation:
As point M is the midpoint of AB, so
AB = AM + BMAM = BMGiven
AB = 8x - 50
AM = 2x + 9
so substituting AB = 8x - 50 and AM = 2x + 9 in the equation AB = AM + BM
AB = AM + BM
8x - 50 = 2x + 9 + BM
8x - 2x - 50 - 9 = BM
6x - 50 = BM
Thus,
BM = 6x - 59
As
AM = BM
so substituting AM = 2x + 9 and BM = 6x - 59 in the equation AM = BM
2x + 9 = 6x - 59
switch sides
6x - 59 = 2x + 9
subtract 2x from both sides
6x - 2x - 59 = 2x + 9 - 2x
4x - 59 = 9
add 59 to both sides
4x - 59 + 59 = 9 + 59
4x = 68
divide both sides by 4
4x/4 = 68/4
x = 17
Thus, the value of x = 17
Therefore, the value of AM will be:
AM = 2x + 9 = 2(17) + 9 = 34 + 9 = 43
Hence, the value of AM = 43
Verification:
AM = BM
2x + 9 = 6x - 59
2(17) + 9 = 6(17) - 59
34 + 9 = 102 - 59
43 = 43
and
AB = 8x - 50 = 8(17) - 50 = 86

The square below has an area of x^2+10x+25 square meters. What expression represents the length of one side of the square?
Answer:
(x+5) m
Step-by-step explanation:
Given that,
The area of a square shape, [tex]x^2+10x+25[/tex]
We need to find the expression for the length of one side of the square.
The area of a square shaped object is given by :
[tex]s=x^2[/tex]
x is side of the square
[tex]s=\sqrt{A} \\\\s^2=x^2+10x+25\\\\=x^2+5x+5x+25\\\\=x(x+5)+5(x+5)\\\\=(x+5)^2\\\\s=(x+5)[/tex]
So, the sides of the square is (x+5) m.
