I need help on this question 5(x - 4) = 12
______________________________
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.) Simplify:Improper fraction form: [tex]\frac{32}{5}[/tex]Mixed number form: [tex]6\frac{2}{5}[/tex]Decimal form: [tex]6.4[/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]
Is a repeating decimal a rational number
A. Yes because it can be written as a/b and a and b are integers and b =0
B. Yes because it can be written in the form a•b where a and b are integers
Answer:
Option A
Step-by-step explanation:
The answer to this question is option A or "Yes because it can be written as a/b and a and b are integers and b =0." Any number that can be written as a fraction is a rational number. In this case repeating decimals can be written as a fraction using different types of algebraic methods making it a rational number.

d-Y-6=-4(x+3)
Answer:
1+1=magelan
2plus2 lapulapu
Answer:
b and d
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 6) and (x₂, y₂ ) = (- 2, 2) ← 2 points on the line
m = [tex]\frac{2-6}{-2+3}[/tex] = - 4
Using (a, b ) = (- 3, 6 ), then
y - 6 = - 4(x - (- 3)), that is
y - 6 = - 4(x + 3) → d
Using (a, b ) = (- 2, 2 ), then
y - 2 = - 4(x - (- 2)) , that is
y - 2 = - 4(x + 2) →b

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)

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.

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.

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°.
