Answer:
-4x+3x power of 2 +2
Step-by-step explanation:
Answer:
3x² - 4x + 2
Step-by-step explanation:
distribute -2 into (3x - 1) and distribute x into (3x + 2)
=> -6x + 2 + 3x² + 2x
combine like terms
=> 3x² - 4x + 2
12 + 6x > 18

split 50 into the ratio 9:1 what is the answer
Answer:
46
Step-by-step explanation:
The numbers 45 and 5, in the ratio of 9:1, when added together, sum up to 50.
To split the number 50 into a specific ratio, 9:1. This means we need to divide 50 into two parts, where one part is nine times larger than the other part.
To split 50 into the ratio 9:1, we need to divide the number 50 into two parts, let's call them "x" and "y." The ratio 9:1 tells us that one part is nine times larger than the other. So, we can express this relationship mathematically as:
x = 9y
Now, we know that the sum of the two parts, x and y, should add up to 50:
x + y = 50
Since we have an expression for "x" in terms of "y," we can substitute it into the second equation:
9y + y = 50
Now, let's combine the y terms:
10y = 50
Next, we isolate "y" by dividing both sides of the equation by 10:
y = 50 / 10
y = 5
Now that we've found the value of "y," we can use it to find "x" using the first equation:
x = 9 * 5
x = 45
So, the two parts are x = 45 and y = 5. We can verify that the ratio is indeed 9:1:
x / y = 45 / 5 = 9
And the sum of the two parts is:
45 + 5 = 50
The numbers 45 and 5, in the ratio of 9:1, when added together, sum up to 50.
In summary, to divide 50 into the ratio 9:1, we found that one part (x) is 45, and the other part (y) is 5. This satisfies the condition that one part is nine times larger than the other, and their sum is 50.

solve: log3(x)+log3(x-2)=log3(x+10)
log3 ( x ) + log3 ( x - 2 ) = log3 ( x + 10 )
log3 ( x )( x - 2 ) = log3( x + 10 )
log3 ( x^2 - 2x ) = log3( x + 10 )
x^2 - 2x = x + 10
x^2 - 3x - 10 = 0
( x - 5 )( x + 2 ) = 0 ==》x = 5 Or x = - 2

Find an equation of variation in which y varies directly as x and y = 60 when x = 0.4. Then find the value of y when x = 2
Answer:
y = 300
Step-by-step explanation:
The equation of variation in which y varies directly as x is written Mathematically as:
y ∝ x
y = k × x
y = kx
Where k = Proportionality Constant
We find k
a) y = 60 when x = 0.4.
60 = 0.4 × k
k = 60/0.4
k = 150
b) find the value of y when x = 2
y = kx
k = 150
Hence,
y = 150 × 2
y = 300

The growth of a certain organism can be modeled by C(t)=10(1.029)^24t, where C(t) is the total number of cells after t hours. Which function is approximately equivalent to C(t)?
1. C(t) =240(0.083)^24t
2. C(t)=10(.083)^t
3. C(t)=10(1.986)^t
4. C(t)= 240(1.986)^t/24
Given:
The function is:
[tex]C(t)=10(1.029)^{24t}[/tex]
Where, C(t) is the total number of cells after t hours.
To find:
The function that is approximately equivalent to C(t).
Solution:
We have,
[tex]C(t)=10(1.029)^{24t}[/tex]
It can be rewritten as:
[tex]C(t)=10(1.029^{24})^{t}[/tex] [tex][\because (a^m)^n=a^{mn}][/tex]
[tex]C(t)\approx 10(1.986)^{t}[/tex] [tex][\because 1.029^{24}\approx 1.986][/tex]
The function [tex]C(t)=10(1.986)^{t}[/tex] is approximately equivalent to C(t).
Therefore, the correct option is 3.

James has a board that is 3/4 foot long he wants to cut the board into pieces that are each 1/8 foot long long division
Answer:
6 pieces can be cut out of the board
Step-by-step explanation:
The complete question is
James has a board that is 3/4 foot long. He wants to cut the board into pieces that are each 1/8 foot long. How many pieces can James cut from the board?
Solution
Given,
The total length of the board is equal to [tex]\frac{3}{4}[/tex] feet
Total number of pieces to made = X
Size of each piece that is cut from the board is [tex]\frac{1}{8}[/tex] feet long
Total number of pieces that can be cut from the board is equal to total size of board divided by size of each sub part
[tex]X = \frac{\frac{3}{4} }{\frac{1}{8} } \\X = \frac{3}{4} * \frac{8}{1} \\X = 3 * 2 \\X = 6[/tex]
Hence, 6 pieces can be cut out of the board

Answer:
78%
Step-by-step explanation:
Ok to solve this we can write this as
80 = [tex]\frac{73+82+85+83+x}{5}[/tex]
We put the equation like this because were finding out how much he needs to get on his 5th test x in order to get a 80%
Your grade is the average of all of your scores hence the divided by 5
We next multiply both sides of the equation by 5 to get
400 = 72+82+85+83+x
400= 322+ x
78 = x
He must get a 78% minimum on his next test to get 80%
