1. Write the absolute value inequality in the form x−b≤c or x−b ≥c that has the solution set −1≤x≤3.
2.Write the absolute value inequality in the form x−b≤c or x−b≥c that has the solution set x≤−9 or x≥−5.
WILL BE MARKED BRAINLEIST!
Answer:
1. We want to write an equation in the form:
Ix - bI ≤ c
Such that the solutions are the range −1 ≤ x ≤ 3
First, the extremes of the range are: - 1 and 3
Half of the difference between these values is:
m = (3 - (-1))/2 = (3 + 1)/2 = 4/2 = 2
Now let's go to the lower extreme, and add this value, we get:
-1 + m = -1 + 2 = 1
(if we go to the upper value and we subtract m, we get the same)
This is the mid-value of the solution interval, and we will define it as M
We now can write the absolute value inequality as:
I x - MI ≤ m
In our case, we get:
Ix - 1I ≤ 2
2.
Now we want to have the solution set given by:
x ≤ -9
x ≥ -5
In this case, we will have an equation of the form:
Ix - MI ≥ m
(before we used the symbol ≤, which means that the solutions are inside the interval, now we use the symbol ≥, which means that the solutions are outside of the interval (-9, -5) in this case).
So let's do the same than in the above case:
m = (-5) - (-9) = (-5 + 9)/2 = 4/2 = 2
M = -9 + 2 = -7
Replacing these in the absolute value inequality we got:
Ix - (-7)I ≥ 2
Ix + 7I ≥ 2

Answer:
y = 170 -3x
Step-by-step explanation:
The marked angles are called "same-side interior angles", or "consecutive interior angles" because they are between the parallel lines and on the same side of the transversal. Such angles are supplementary.
y + (3x +10) = 180
y = 180 -(3x +10) . . . . . subtract everything on the left that is not y
y = 170 -3x . . . . . . . . . simplify

Answer:
∠ADE = 59°
Step-by-step explanation:
4x + 15° + 13x + 7° = 90°
combine like terms:
17x + 22° = 90°
subtract 22° from both sides of the equation:
17x = 68°
divide both sides by 17:
x = 4
∠ADE = ∠CBD = 13(4) + 7 = 59°
Answer:
m∠ADE = 59°Step-by-step explanation:
m∠ADE is the same as m∠BCE, so
m∠ADE = (13x+7)°
In rectangle all angles are 90°, so:
4x + 15 + 13x + 7 = 90
17x + 22 = 90
17x = 90 - 22
17x = 68
x = 68÷17 = 4
Therefore:
m∠ADE = (13×4+7)° = 59°

Lola spends one-fourth of her monthly salary on her car payment. She spends $250 on her car payment. Write and solve an equation to determine Lola's monthly salary.
Answer:
$24 is her allowance. 1/3 of her allowance is $8. So you would multiply 8 times 3 because 8 is just 1/3 of her allowance and you want to find her total weekly allowance. 8 x 3 = 24

The base of a cone has a radius of 6 centimeters. The cone is 7 centimeters tall. What is the volume of the cone to the nearest tenth
Answer:264cm^3
Step-by-step explanation:
Volume of a cone= 1/3×A×h, where A is base area
Base area=πr^2
=22/7× 6^2
=113.143cm^2
Volume=1/3×113.143cm^2×7cm

Answer:
SA = 997.88 mm²
Step-by-step explanation:
height² = 20.5² - 13.3² = 420.25 - 176.89 = 243.36
height = √243.36 = 15.6
SA = (16 x 13.3) + (16 x 20.5) + (16 x 15.6) + (0.5 x 2 x 13.3 x 15.6)
SA = 212.8 + 328 + 249.6 + 207.48 = 997.88 mm²

Solve for x . x/2 + 1.1= -2.1
Answer: x = 1.6
Step-by-step explanation:
Start by Identifying what you need to keep, in this case that would be X. In order to solve for x, you would need to get rid of any co-efficients. (example: +1.1) To get rid of them, you have to do the opposite action of what it's doing to the equation. (subtraction)
1.1- (-2.1) = 3.2 (if you subtract a negative, it turns positive/ you add) leaving you with x/2 = 3.2.
Now that we have our coefficient out the way, we have to get rid of the division so we can only solve for x. We do that by dividing the remainder of the equation by 2
3.2/2 = 1.6
Leaving us with the answer, x = 1.6

How do you know which number is the largest when you compare integers?
Answer:
Step-by-step explanation:
Lets take 4905 and 802
Firstly to figure out which of these two numbers is bigger we first look at the highest place value that either one of these two numbers have
In this case its 4 in the thousands place in the number 4905
Next we look at which number 802 has in the thousands place
In this case there is no number or 0
4 is bigger than 0 so we know that 4905 is bigger than 802
Lets take another example
4905 and 8204
Here both numbers have a number in the thousands place on is 8 and the other is 4
8 is bigger than 4 so 8204 must be larger
I'm just saying comparing integers should come very easily and you really don't need to think much to figure this out
I'm guessing you mean how do you compare numbers which are non-integers like 4/6 or 4/5 and this is quite easy
There are multiple ways but one method is to just multiply the denominator of one fraction with the numerator of the other and do the same for the other fraction
lets take 4/6 and 4/5
4*5=20
and 4*6= 24
4/6 we can assign 20
and 4/5 is 24
the bigger number is 24 so 4/5 is bigger
Shanti is making a patchwork quilt. Each piece of fabric has a black star on it. She uses the grid shown to plan the locations of the different fabric squares.
a. What transformation maps square 1 onto square 2?
b. What transformation maps square 2 onto square 3?
c. What transformation maps square 1 onto square 5?
Answer:
A) Translation
B) Reflection
C) Rotation
Step-by-step explanation:
The transformation types in mathematics are;
Reflection, translation, rotation and dilation.
We can see that the squares are all the same size, it's just the position of the stars that will aid us in knowing the specific transformation.
A) We can see that square 2 is the exact same thing as square 1. Just that it was shifted to the right of square 1. Thus, it was translated and the transformation is translation.
B) We can see that the star in square 3 is the exact mirror copy and location from square 2. Thus, this is a reflection.
C) We can see that the position of the star in square 5 is top while that in square 1 is at the left corner. This can only be achieved by rotation.
