3(-4+x)<-33 I need to solve for x
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
x<−7
Answer:
x<−7

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

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

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.

b. For new customers, there is an additional one-time $100 service fee. Repeat the previous problem for new customers.
c. When the two equations are graphed in the coordinate plane, how are they related to each other geometrically?
1. Find f(-2) if : *
f (x) = 4 |x – 4| + 2
-20

Answer: 34
f(-2) means inserting 'x = -2' into the equation.
x = -2
4*|-2 -4| +2
= 4*|-8| + 2
= 4*8 + 2
= 32 + 2

y = -1/2x + 1Which 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.
