The absolute value equation is:
|x + 1.3| = x + 1.3
Working with absolute value equations:
The absolute value equation that we have is:
|x - b| = c
And we want that the solution set is all the numbers larger than -1.3
Now, remember that:
| something| ≥ 0.
So the absolute value is always equal or larger than zero.
So, for example, the equation:
|x| = x
Only is true if x ≥ 0, because if x is smaller than zero, for example x = -2, we would have:
|-2| = -2
2 = -2
Which is false.
Now we want to have solutions larger than -1.3 instead of larger than zero, so we can write:
|x + 1.3| = x + 1.3
The solution of this equation is the given set.

Answer:
[tex]\sf y = \dfrac{17}{2}[/tex]
explanation:
[tex]\sf 7y-4=9y+13-4y[/tex]
collect variables in one side
[tex]\sf 7y -9y +4y = 13 +4[/tex]
simplify by addition and subtraction
[tex]\sf 2y = 17[/tex]
divide both sides by 2
Hence, ,final answer:
[tex]\sf y = \dfrac{17}{2}[/tex]
Answer:
A. y = 17/2
Step-by-step explanation:
Given equation:
7y - 4 = 9y + 13 - 4y
Collect like terms:
7y - 4 = 9y - 4y + 13
Combine like terms:
7y - 4 = 5y + 13
Subtract 5y from both sides:
2y - 4 = 13
Add 4 to both sides:
2y = 17
Divide both sides by 2:
y = 17/2

Find the value of x that will make A||B
Answer:
x = 20
Step-by-step explanation:
When two parallel lines are intersected by a transversal, then the alternate exterior angles are congruent.
5x + 20 = 3x + 60
Now subtract 3x form both sides
5x - 3x + 20 = 3x - 3x + 60
2x + 20 = 60
Subtract 20 from both sides
2x + 20 -20 = 60 - 20
2x = 40
Divide both sides by 2
x = 40/2
x = 20

The number of chairs Amal can paint varies directly with the amount of time she spends painting. Amal can paint 7 chairs in 3 hours. How many chairs can Amul paint in 15 hours? Enter your answer in the box.
Answer:
35
Explaination:
This problem can be represented by the equation: (7/3)=(x/15) Then solve for x, which is 35.
Amul can paint 35 chairs in 15 hours
Let the number of chairs Amal can paint be represented as N
And amount of time she spends painting be represented as t
such that
The number of chairs Amal can paint varies directly with the amount of time she spends painting will be expressed as
N∝t
Introducing the constant of proportionality,K becomes
N=Kt
Amal can paint 7 chairs in 3 hours.K becomes
N=Kt
7=K3
K=7/3
Now if Amul paint in 15 hours, she would paint
N=Kt
N=7/3 X 15
N=35 Chairs

Can someone please answer this it would mean the world to me cause im failing right now
Answer:
Alright, for question 7, the angle pair relationship is that they are corresponding angles.
So, 17x - 34 = 13x - 14. This means that 4x = 20, and x = 5 :)
For question 8, the angles are a linear pair. They are supplementary (adding to 180) :)
So, 37x - 17 + 33x - 13 = 180
This means taht 4x = 210, and x = 52.5? (I'm not sure if I screwed up on the arithmetic on this one, please correct if you find any mistakes!)

Jabari owns 100 shares of Stock A and 45 shares of Stock B. For the past month, his stocks have been
fluctuating inversely. Stock A decreased by m cents per share and Stock B increased by n cents per share.
Which equation can be used to find the total change in value of Jabari's shares per month?
A V = (100.-m)+(45.n)
B V = (100-m)+(45.-n)
V = 100(4.-m)+45(4.n)
D V=145(-mºn)
Answer:
Answer is A
(100*-m)+(45*n)
Step-by-step explanation: because stock a decreases per sock so your going to multiply 100 times -m because it is decreasing so it will be negative
Then it will be 45*n because it increase per number of stocks so you multiply 45 which is the number of stocks times n

A family is purchasing a house and needs to finance a $195,000 mortgage from the bank with an annual percentage rate (APR) of 5.3%. The family is financing it over 30 vears and making monthly payments. What would their monthly payment be?
Answer:
a) payment: $1082.84
b) interest: $194,822.40
Step-by-step explanation:
The monthly payment on the mortgage can be found using the given formula with the given values of principal (P=195000), interest rate (r=0.053), and time period (t=30). The value of n is 12, corresponding to the number of months in a year.
a)The monthly payment is ...
[tex]k=\left(1+\dfrac{r}{n}\right)^{nt}=\left(1+\dfrac{0.053}{12}\right)^{12\cdot30}\approx 4.88661119\\\\\text{monthly payment}=\dfrac{P\cdot\dfrac{r}{n}\cdot k}{k-1}=\dfrac{195000\cdot0.0044166667\cdot4.88661119}{4.88661119-1}\\\\\boxed{\text{monthly payment}=\$1082.84}[/tex]
__
b)The interest owed is the difference between the total of monthly payments and the principal of the loan:
interest owed = (360)(1082.84) -195000 = 194,822.40
The interest owed over 30 years is $194,822.40.

Answer:
y=252/5=50.4
Step-by-step explanation:
[tex](A)\ 9y-252=4y\\(B)\ 5y=252\\(C)\ y= \frac{252}5 = 50.4[/tex]
In step A we multiplied both sides by the least common multiple of the denominators, in order to deal with only integers for as long as possible.
In step B you subtract 4y and add 252 to both sides ("moving them on the other end of the equal sign").
In step C you finally divide by 5 to isolate y.

35 + 45
= 80
Now 80 has to equal to;
5 x (7 + y) ( where 'y' is our unknown number)
So we set up the equation:-
80 = 5 x (7 + y)
80 = 35 + 5y
-35 -35
45 = 5y
/5 /5
9 = y
Let's double check:
80 = 5 x (7 + y)
80 = 5 x (7 + 9)
80 = 35 + 45
80 = 80, we are correct.
