Answer:
|x+2| > 3
Step-by-step explanation:
We know that if |x| > a then (-a > x) ∨ (x > a).
(x+5 > 6) ∨ (x+5 < 0) ⇒ (0 > x+5) ∨ (x+5 > 6) |-3 ⇒
⇒ (-3 > x+2) ∨ (x+2 > 3) ⇒ |x+2| > 3

In Exercises 17-20, find the value of x so that the function has the given value. 17. f(x) = 8x - 7; f(x) = 17
18. g(x) = -4x + 7; g(x) = 27
19. f(x) = {* – 1; f(x) = 9
20. h(x) = 6 – Şx; h(x) = -2
Answer:
17.) x = 3
18.) x = -5
I couldn't do 19.) and 20.) for you because there are weird symbols that I believe you mistakenly input. But I'm sure you now get the gist of how to solve such problems. Peace <3
Step-by-step explanation:
All you really have to do for all of the problems is substitute your value of "x" for the function.
17.) f(x) = 8x - 7; f(x) =17
17 = 8x -7 ---- substitute 17 for f(x), add 7 on both sides
24 = 8x ------ divide 8 on both sides
x = 3
18.) g(x) = -4x + 7; g(x) = 27
27 = -4x + 7 substitute 27 for g(x), subtract 7 on both sides
20 = -4x
x = -5

Joel runs the same distance
every day. Last week he ran
28 miles in 4 days. Find the
constant of proportionality
that relates the number of
miles, y, to the number
of days, x?
The constant of proportionality that relates the number of miles y, to the number of days x is [tex]\frac{1}{7}[/tex] .
What is proportionality?
In general, the word "proportion" is used to describe a part, share, or amount that is compared to an entire. Two ratios or fractions being equal is expressed by an equation or a statement. An analysis of two numbers in terms of their proportion. A ratio is said to be directly proportional to another if two sets of supplied numbers are increasing or decreasing in the same ratio. With the "::" or "=" symbol, proportions are indicated.
Here if the days are increasing then distance also increased . Then days directly proportional to the distance .
=> Number of days ∝ Total distance
=> x∝y
To remove proportion we hate to add constant K.
=> x= ky
Here if he runs 28 miles in 4 days. x=4, y=28.
=> 4 = k*28
=> k = 4/28
=> k = [tex]\frac{1}{7}[/tex]
the equation is x = [tex]\frac{1}{7}[/tex]y
Hence the constant of proportionality that relates the number of miles y, to the number of days x is [tex]\frac{1}{7}[/tex] .

What is the GCF of 52/65?
Answer:
The greatest Common factor of 52/65 is 13!
Step-by-step explanation:
Hope this helps :)
Pls make brainliest :p
And have an amazing day <3
Answer:
13
Step-by-step explanation:
The GCF of numbers can be found by first finding the prime factors of the numbers.
52 = 2^2 * 13
65 = 5 * 13
The GCF is the product of common factors with lower exponent.
The only common factor is 13.
GCF = 13
To reduce the fraction, divide the numerator and the denominator by the GCF.
(52/13) / (65/13) = 4/5
Write the prime factorization of 12. Use exponents when appropriate and order the factors from least to greatest (for example, 2235).

how much does carl earn per hour?show your work .
Answer:
Step-by-step explanation:
From the table showing in the diagram, Let's pick the data in the first row:
Time = 3 hours
Money earned = $45
The amount of money Carl earns per hour is calculated as:
3 hours = $45
1 hour = ?
Cross Multiply
1 hour x $45 / 3 hours
= $15
Let's confirm our answer using the data in the last column
Time = 10 hours
Money earned = $150
The amount of money Carl earns per hour is calculated as:
10 hours = $150
1 hour = ?
Cross Multiply
1 hour x $150 / 10 hours
= $15
Therefore, the amount of money Carl earns per hour is $15
Answer:
he earns 15 dollars per hour. 45/3 is 15

In the figure below, C is between A and D, and B is the midpoint of AC. If BC= 3 and BD=10, find AD.
The line segment AD measures 13 units.
What is a line segment?
A line segment in geometry has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a line that links two places. The difference between a line and a line segment is that a line has no endpoints and can go on forever in either direction.
A line segment AD is given.
Four points A, B, C and D are placed.
It is given that measurement of BC = 3 units.
Also, measurement of BD = 10 units.
Since, B is the midpoint of AC, so -
AB = BC
So, the measurement of AB = 3 units
The measurement of CD can be found as -
CD = BD - BC
CD = 10 - 3
CD = 7 units
So the measurement for line segment AD is -
AD = AB + BC + CD
AD = 3 + 3 + 7
AD = 13 units
Therefore, the measurement value is 13 units.

[tex]4x + 6 = -334[/tex]
[tex]4x = -340[/tex]
[tex]x = -85 [/tex]
Step-by-step explanation:
[tex]Thanks!!!!![/tex]
Answer:
the first number is x (x ∈ Z)
=> four consecutive integers are x, x + 1, x +2, x + 3
because the sum of them = -334, we have:
x + (x + 1) + (x + 2) + (x + 3) = -334
⇔ 4x + 6 = -334
⇔ 4x = -334 - 6 = -340
⇔ x = -340/4
⇔ x = -85
=> 4 consecutive integers are -85; -84; -83; -82
