Reduce by cancelling the common factors.
(13)x−1=27 Convert the exponential equation to a logarithmic equation using the logarithm base (13) of the right side (27) equals the exponent (x−1)log13(27)=x−1

what two numbers add up to be 116.5
Answer:
58.25
Step-by-step explanation:
116.5 / 2
= 58.25
Hope this helps!!
58.25+58.25
Those are the two numbers that add up to that number (116.5)
Btw there are also MULTIPLE numbers that add up to 116.5, I'm just putting the one that makes the most sense.

PLZZ HELPP IM FAILLING THIS CLASS
Answer:
Hope this helps!!! :)
Step-by-step explanation:
#1: if there is buy 1 get 1 free, then buy 6 get 3 free. so 2.8 times 3 = $8.4
#2: 4 for $3. break it up to 1 for $0.75. now 0.75 times 6 = $4.5
#3: the second one. $4.5 < $8.4
#4: 45 times 12 = $54
Plz help me with this
Answer:
The first choice
Step-by-step explanation:
It says that its decreasing so the slope is negative.
It also starts of with 565 so that's the y intercept
[tex] \sqrt[3]{( \frac{1}{8} - x)} = - \frac{1}{2} [/tex]
what is the answer?
∛(1/8 - x) = -1/2
Take the 3rd power of both sides and solve:
(∛(1/8 - x))³ = (-1/2)³
1/8 - x = -1/8
2/8 = x
x = 1/4
2. Solve:
у = 3х
x = -2y + 70
Answer: (10,30)
Step-by-step explanation:
y = 3x
x = -2y + 70
Solve by using the substitution method. Substitute the value for x into the first equation and solve for y.
y = 3(-2y + 70) Multiply it out
y = -6y + 210 Add 6y to both sides
+6y +6y
7y = 210
y = 30
Since y is equal to 30, input the value for y into the equation and solve for x.
30 = 3x Divide both sides by 3
x = 10
I don't know how doing this
Slope intercept form - y = m(x) + b. m represents slope, b represents the y-intercept. You should be able to plug in any value for y and x into the equation, and it should result in a true statement.
The y-intercept is easy to find. It is the point where X is equal to zero and the graph line crosses through the y axis. In this case, y intersects at -2. Since we insert the y intercept at b, we can go ahead and plug it in there.
y = m(x) + b > y = m(x) - 2
Since there is only one option with the y intercept equalling -2, you can go ahead and pick D) y = -x - 2 as your answer, since no other options have the correct y-intercept.
A gym membership charges a one-time application fee of $15, plus $32 each month. Which of the following equations could represent the total cost, y, for x number of months?
A.y = 32x + 15
B.y = 15x + 32
C.y = 47x
D.15y = 32x
Answer:
The answer is A. y =32x + 15
Step-by-step explanation:
The reason behind this is the rate. The amount of money each month is the slope (m). The additional fee would be the b.

In the given figure, ABCD is a trapezium in which AD || BC,
ABC = 90°, AD = 16 cm, AC = 41 cm and BC = 40 cm. Find the
area of the trapezium,
Answer:
252 cm²
Step-by-step explanation:
Find AB:
AB² = 41² - 40²
AB² = 81
AB = √81
AB = 9 cm
Area of the trapezium = ½(a + b) × h
Where,
a = 16 cm
b = 40 cm
h = 9 cm
Area = ½(16 + 40) × 9
Area = ½(56)×9
Area = 252 cm²
3x + 9 = -45 step by step please
Answer:
x=- 18
Step-by-step explanation:
3x+9= -45
3x=-45-9
3x=-54
x=-54/3
x= -18

What is the range of the graph above?
Element X is a radioactive isotope such that every 20 years, its mass
decreases by half. Given that the initial mass of a sample of Element X is 410
grams, how long would it be until the mass of the sample reached 270 grams,
to the nearest tenth of a year?
Answer:
12.1
Step-by-step explanation:
y=a(1/2)^t/h
270=410(1/2)^t/20
Divide both sides by 410
0.6585365854 = (1/2)^t/20
Log Both sides
Log(0.6585365854) / Log(1/2)
.6026645024= t/20
20 x .6026645024 = t
12.05329005 to the nearest tenth is 12.1 = t
The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there are 1500 after 1 day, what is the size of
the colony after 3 days? How long is it until there are 80,000 mosquitoes?
The size of the colony after 3 days is approximately mosquitoes.
Answer:
There are 2,500 misquitos after 3 days and it takes 158 days to reach 80,000 mosquitos.

Answer:
x = 4
Well basically 20 divided by 5 is 4. which makes this clearly the answer because the slope is 20/x which is being divided. So when you times 5 x 4 you get 20. It all comes together in a way.
Write the equation of the line that passes through (-3,9) and is parallel to y = -2x + 5
Answer:
y = -2x +3
Step-by-step explanation:
Parallel lines always have the same slope
To insert the point, use the slope intercept formula: y =mx+b
insert y (9)
insert x (-3)
insert the slope -2
9 = (-2)(-3) + b
9 = 6+b
subtract 6 from both sides
3 = b
