factorize -pq -pr +mq +mr
Answer:
(q + r) (m - p)
Explanation:
-pq - pr + mq + mrFactor out common term 'p'= -p(q + r) + mq + mr
Factor out common term 'm'= -p(q + r) + m(q + r)
Factor out common term '(q + r)'= (q + r) (-p + m)
(q + r) (m - p)- PNW

Answer:
−7
Step-by-step explanation:
Answer:
Let's solve your inequality step-by-step.
3(−4+x)<−33
Step 1: Simplify both sides of the inequality.
3x−12<−33
Step 2: Add 12 to both sides.
3x−12+12<−33+12
3x<−21
Step 3: Divide both sides by 3.
3x/3 < −21 /3

the midpoint of a line segment is (-3,4). The endpoints of the line segment are (x,9) and (-4,1). What is the value of x
Answer:
Step-by-step explanation:
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

need help
Answer:
b=35
Step-by-step explanation:
Diagonals of a parallelogram always bisect each other, splitting it into two equal sections.
This means, b-8 is equal to 2b-43
b-8 = 2b-43
b+35=2b
b=35

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.

Question 3 of 25
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 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.

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.

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.
