To write equivalent expressions, we multiply all the quantites by the same number.
8x - 12 = ( 2 x 8x) - (2 x 12) = 16x - 24
Using the same method, you can write 3 equivalent expressions :
16x - 24 ; 24x - 36 ; 32x - 48
if 8^{y}=18^{y+2} what is the value of y?
Answer:
-8
Step-by-step explanation:
both 8^-8 and 16^-8+2 equal 5.9605
[tex][Hello,BrainlyUser][/tex]
Answer:
y = -8
Step-by-step explanation:
Create equivalent expressions in the equation that all have equal bases.
[tex]2^3^y=2^4^(^y^+^2^)[/tex]
Since the bases are the same, then two expressions are only equal if the exponents are also equal.
[tex]3y=4(y+2)[/tex]
Simplify
[tex]4(y+2).[/tex]
Apply the distributive property.
[tex]3y=4y+4*2[/tex]
Multiply 4 by 2
[tex]3y=4y+8[/tex]
Subtract 4y from both sides of the equation.
[tex]3y-4y=8[/tex]
Subtract 4y from 3y.
[tex]-y=8[/tex]
Multiply each term in −y=8 by −1
[tex]y=-8[/tex]
Hence, Answer is y = -8

In order to join a dancing club there is a $30 startup fee and a $4 monthly fee. Write an equation in slope intercept form that models this situation.
Answer:
y = 4x + 30
Step-by-step explanation:
The startup fee is $30 and must be paid before you begin. This means that 30 in the y-intercept. You pay $30 at 0 months. Then you have to pay $4 every month after that. This means that 4 is the slope. So, after x months, the total amount you have paid, y, is
y = 4x + 30

Element X is a radioactive isotope such that every 22 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 1200 grams, how long would it be until the mass of the sample reached 800 grams, to the nearest tenth of a year?
Step-by-step explanation:
s1 = 1200 g
s2 = 1200×2^(-1/22)
s3 = 1200×2^(-2/22)
...
s23 (22 years later) = 1200×2^-22/22 ≈ 1200×2^-1 = 1200/2
sn = 1200×2^(-(n-1)/22)
what is the n, so that the result is 800 g ?
800 = 1200×2^(-(n-1)/22)
800/1200 = 2^(-(n-1)/22)
2/3 = 2^(-(n-1)/22)
log2(2/3) = -(n-1)/22
22×log2(2/3) = -(n - 1) = -n + 1
n = -22×log2(2/3) + 1 = 13.86917502...
since we stared counting with n=1 for the starting quantity, the number of years is truly 1 less than n (s2 is after 1 year, s3 after 2 years ...).
so, we know for n = 13.86917502..., that in fact
12.86917502... ≈ 12.9 years have passed until the mass of the sample reached 800g.
Help solve this math problem thing pleasereeee
Step-by-step explanation:
We have the equation y = 2x - 5
To complete the table of values substitute each of the x values into the equation
When x = 0
y = 2(0) - 5 which means y =(2 × 0) - 5 = -5
The coordinates you plot are (0,-5)
When x = 1
y = 2(1) - 5 which means y = (2 × 1) - 5 = -3
The coordinates you plot are (1,-3)
When x = 2
y = 2(2) - 5 which means y = (2 × 2) - 5 = -1
The coordinates you plot are (2,-1)
When x = 3
y = 2(3) - 5 which means y = (2 × 3) - 5 = 1
The coordinates you plot are (3,1)
When x = 4
y = 2(4) - 5 which means y = (2 × 4) - 5 = 3
The coordinates you plot are (4,3)
When x = 5
y = 2(5) - 5 which means y = (2 × 5) - 5 = 5
The coordinates you plot are (5,5)
How many 1/2 liter bottles of lemonade can you fill from a 2 1/2 liter container explain your answer
Answer:
5
Step-by-step explanation:
Container volume = 2 1/2 liters
Bottle volume = 1/2 liters
No. of bottles = Container vol. / Bottle vol.
= 2 1/2 / 1/2
= 5/2 / 1/2
= 5

The area of the tile is 12 square inches.
How to get the area of a rectangle?
For a rectangle of length L and width W, the area is given by:
A = L*W
In this case, we can see that the width is 2 inches and the length is 6 inches, then the area of this rectangle will be:
A = 6in*2in = 12 in^2
So we can conclude that the area of the tile is 12 square inches.

Slope of (7, -2) and (2, -6)
Answer:
[tex]\boxed{\sf{m=\frac{4}{5}}}[/tex]
Step-by-step explanation:
In order to solve this problem, we will use the slope.
Slope:
[tex]\sf\dfrac{Y_2-Y_1}{x_2-x_1}=\dfrac{rise}{run}[/tex]
y2=(-6)
y1=(-2)
x2=2
x1=7
Solve the problem by rewriting it down.
[tex]\sf{\dfrac{(-6)-(-2)}{2-7} }=\dfrac{(-6)+2}{2-7}=\boxed{\dfrac{4}{5} }[/tex]
m=4/5
Therefore, the slope is 4/5.

A dog is leashed to the corner of a house. How much running area does the dog have? Round your answer to the nearest square foot, if necessary.
Answer:
300pi square feet
Step-by-step explanation:
the dog can move inside of the 3/4 of a circle
the area of a circle is the radius squared times pi
20*20*pi=400pi
Since the house takes up 1/4 of the circle the dog is left with 3/4
400pi*3/4=300pi

Answer:
[tex]y=11*3^x[/tex]
Here is the graph showing this function.
Answer:
[tex]\sf y = 11(3)^x[/tex]
given points: ( 0, 11) , (2,99)
solve for 1st
[tex]\sf y = ab^x[/tex]
[tex]\sf 11 = ab^0[/tex]
since we know [tex]\sf b^0 = 1[/tex]
[tex]\sf 11 =a[/tex]
solve for 2nd
[tex]\sf y = ab^x[/tex]
[tex]\sf 99 = ab^2[/tex]
[tex]\sf \dfrac{99}{b^2} = a[/tex]
solve simultaneously:
[tex]\sf 11 = \sf \dfrac{99}{b^2}[/tex]
[tex]\sf 11 b^2= \sf 99}[/tex]
[tex]\sf b^2= 9[/tex]
[tex]\sf b = 3[/tex]

2/4 + 3/9 in Modeling Fractions?
Answer: 13/12
Step-by-step explanation:
Reduce the fraction 3/9 to the lowest terms by extracting and canceling out 3.
The least common multiple of 4 and 3 is 12. Convert 3/4 and 1/3 to fractions with denominator 12.
Since 9/12 and 4/12 have the same denominator, add them by adding their numerators.
Add 9 and 4 to get 13.
