______________________________
1.) Divide both sides by 5: [tex]5[/tex] ÷ [tex]5=[/tex] Cancels out[tex]12[/tex] ÷ [tex]5=[/tex] [tex]\frac{12}{5}[/tex]- I changed [tex]\frac{12}{5}[/tex] to a fraction instead, and you'll see why on the next step.
2.) Add 4 to both sides:[tex]-4+4=[/tex] Cancels out[tex]4=\frac{20}{5}[/tex]- 4 in fraction form would best be [tex]\frac{20}{5}[/tex] in this situation.
3.) Add: [tex]\frac{12}{5} + \frac{20}{5} = \frac{32}{5}[/tex]- Since [tex]\frac{12}{5}[/tex] and [tex]\frac{20}{5}[/tex] have the same denominator, all you have to do is add the numerators.

4 ≤ y + 2 ≤ -3(y-2)+24
Answer:
[tex]4\le \:y+2\le \:-3\left(y-2\right)+24\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:2\le \:y\le \:7\:\\ \:\mathrm{Interval\:Notation:}&\:\left[2,\:7\right]\end{bmatrix}[/tex]
The solution graph is also attached.
Step-by-step explanation:
Given
[tex]4\:\le \:y\:+\:2\:\le -3\left(y-2\right)+24[/tex]
as
[tex]\mathrm{If}\:a\le \:u\le \:b\:\mathrm{then}\:a\le \:u\quad \mathrm{and}\quad \:u\le \:b[/tex]
so
[tex]4\le \:y+2\quad \mathrm{and}\quad \:y+2\le \:-3\left(y-2\right)+24[/tex]
solving the intervals
as
[tex]4\le \:y+2[/tex]
[tex]y+2\ge \:4[/tex]
subtract 2 from both sides
[tex]y+2-2\ge \:4-2[/tex]
[tex]y\ge \:2[/tex]
also
[tex]y+2\le -3\left(y-2\right)+24[/tex]
[tex]y+2\le \:-3y+30[/tex]
subtract 2 from both sides
[tex]y+2-2\le \:-3y+30-2[/tex]
[tex]y\le \:-3y+28[/tex]
Add 3y to both sides
[tex]y+3y\le \:-3y+28+3y[/tex]
[tex]4y\le \:28[/tex]
Divide both sides by 4
[tex]\frac{4y}{4}\le \frac{28}{4}[/tex]
[tex]y\le \:7[/tex]
so combining the intervals
[tex]y\ge \:2\quad \mathrm{and}\quad \:y\le \:7[/tex]
Merge overlapping intervals
[tex]2\le \:y\le \:7[/tex]
Therefore,
[tex]4\le \:y+2\le \:-3\left(y-2\right)+24\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:2\le \:y\le \:7\:\\ \:\mathrm{Interval\:Notation:}&\:\left[2,\:7\right]\end{bmatrix}[/tex]

What would the exponential equation be ?
Answer:
The equation of the exponential function will be:
[tex]f\:\left(x\right)\:=\:ab^x[/tex]
[tex]=\:\frac{3}{2}\left(2\right)^x[/tex]
Step-by-step explanation:
Given the table
Day Bacteria
1 3
2 6
3 12
4 24
5 48
as
the x values have the same increment i.e. +1and
the y values have common ratio i.e. 6/3 = 2, 12/6=2, 24/12=2so it is indeed an exponential function
As we know that the exponential function is of the form
[tex]f\:\left(x\right)\:=\:ab^x[/tex]
As we know that the y-intercept of [tex]f\:\left(x\right)\:=\:ab^x[/tex] is (0, a).
so
[tex]\frac{3}{a}=2[/tex] ∵ common ratio = successor y-value ÷ previos y-value
[tex]a=\frac{3}{2}[/tex]
so the value of a will be: 3/2
We also know that the common factor i.e. multiplier is 2 in this table, we know the value for b is 2.
Therefore, the equation of the exponential function will be:
[tex]f\:\left(x\right)\:=\:ab^x[/tex]
[tex]=\:\frac{3}{2}\left(2\right)^x[/tex]

Answer:
The value of x is 9
Step-by-step explanation:
The measure of the exterior angle at a vertex of a triangle equals the sum of the measures of the two opposite interior angles to this vertex
In the given figure
∵ ∠DFG is an exterior angle at vertex F
∵ The angles of measures (5x - 7) and 89° are the opposite interior
angles to the vertex F
∴ m∠DFG = (5x - 7) + 89
∵ m∠DFG = 14x + 1
→ Substitute it in the equation above
∴ 14x + 1 = 5x - 7 + 89
→ Add the like terms in the right side
∵ 14x + 1 = 5x + 82
→ Subtract 1 from both sides
∵ 14x + 1 - 1 = 5x + 82 - 1
∴ 14x = 5x + 81
→ Subtract 5x from both sides
∴ 14x - 5x = 5x - 5x + 81
∴ 9x = 81
→ Divide both sides by 9
∴ x = 9
∴ The value of x is 9
Sandy receives a $50000 salary for working as an engineer. If Sandy spends 60% of her
salary on expenses each year, then how much money does Sandy have to spend on
expenses? Round your answer to the nearest whole number.
Answer:
Step-by-step explanation:
50,000 * 60%= 30,000
If Sandy receives a $50000 salary for working as an engineer. If Sandy spends 60% of her salary on expenses each year, then Sandy spends $30,000 on expenses.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Given that, Engineer Sandy earns a salary of $50000 per year. If Sandy spends each year 60% of her income on expenses,
We have to find the amount Sandy has to spend on expenses,
The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
The amount spend on the expenses is,
Expenses = 60% of the salary
Expenses =60/100 × $50000
Expenses = 30,000
Thus, if Sandy receives a $50000 salary for working as an engineer. If Sandy spends 60% of her salary on expenses each year, then Sandy spends $30,000 on expenses.

Given the endpoint x(11,-2) and the midpoint (4,3) find the missing endpoint y. Write answer as order pair.
9514 1404 393
Answer:
(-3, 8)
Step-by-step explanation:
For m the midpoint of xy, we have ...
m = (x+y)/2 ⇒ y = 2m-x
y = 2(4, 3) -(11, -2) = (2·4 -11, 2·3 +2)
y = (-3, 8)
An angle measures 86° less than the measure of its supplementary angle. What is the measure of each angle?
The angle if an angle measures 86° less than the measure of its supplementary angle is 133.
Supplementary angles are two angles whose measures add up to 180° .
Supplementary Angles
Let the measure of one of the supplementary angles be a .Measure of the other angle is 2 times a .So, measure of the other angle is 2a .If the sum of the measures of two angles is 180° , then the angles are supplementary.Let the angle be "x".
Its supplementary angle is "180-x"
Equation:
180 - x - x = 86
180 - 2x = 86
2x = 180 - 86
2x = 94
x = 47
Angle x = 47 degrees
supplementary angle is "180-x"
= 180 -47
= 133
Hence , If an angle is 86° smaller than its supplementary angle, the angle is 133°.

A shopper bought 6 shirts and 8 hats for $700. A week later, at the same prices, he bought 9 shirts and 6 hats for $660. What was the cost of one shirt?
Answer:
Cost of one shirt = $ 30
Step-by-step explanation:
Let cost of 1 shirt = s
Cost of 1 hat = h
A shopper bought 6 shirts and 8 hats for $700.
6s + 8h = 700 -------------------(I)
A shopper bought 9 shirts and 6 hats for $660
9s + 6h = 660 -----------------(II)
Multiply equation (I) with 9 and multiply equation (II) with (-6) and then add. SO, now 's' will be eliminated and we can find the value of 'h'
(I) * 9 54s + 72h = 6300
(II)*(-6) -54s - 36h = - 3960 {Now add}
36h = 2340
h = 2340/36
h = 65
Cost of one hat = $ 65
Substitute h = 65 in equation (I)
6s + 8 * 65 = 700
6s + 520 = 700
6s = 700 - 520
6s = 180
s = 180/6
s = 30
Cost of one shirt = $ 30
Answer: One shirt is $30

Caroline's family took a road trip to the Grand Canyon. Caroline fell asleep 58% of the way through the trip. If Caroline fell asleep after they had travelled 348 miles, what was the total length of the trip?
Answer:600 miles
Step-by-step explanation:
Hello!
So you know that 348 miles is equal to 58% so you want to figure out what 1% of the total trip is
348 / 58 = 6
You know that 1% of the trip is 6 miles so now to figure out what the total trip is you multiply 6 by 100
6 * 100 = 600
So you know that the total length of the trip is 600 miles long.
