Please help!!! I would like an explanation along with your answer. Thanks

Answer:

Step-by-step explanation:

The number of months is our unknown, which we will call x. y is the amount she saves. Representing the fact that she puts $10 away per month is 10x. If she puts $300 down initially and then adds 10 per month to that, the first equation is

y = 10x + 300

The same goes for the second option. Putting $30 away every month is represented as 30x, and if she is starting with 100 and adding 30 a month to it, the second equation is

y = 30x + 100

We are being asked to find the number of months where the amount Tina saves is equal. Since y is the amount Tina has saved and we want to know when these amounts are equal, we will set the equations equal to each other and solve for x, the number of months.

10x + 300 = 30x + 100 and

200 = 20x so

x = 10. After 10 months, Tina will have saved the same amount of money regardless of which option she has chosen. This is only true for 10 months though. After that, one will show more of a savings than the other.

To find the x and y intercepts, we have to plug 0 into x and y respectively.

4(0) + 7y = -84

Simplify.

7y = -84

Divide both sides by 7

y = -12

The y-intercept = (0, -12)

4x + 7(0) = -84

Simplify.

4x = -84

Divide both sides by 4

x = -21

The x-intercept = (-21, 0)

Sam's cookies = $16 for 12

Charlie's cookies = $21 for 12

$5 more when buying Charlies other than Sam's

Answer:

x = g + c

Step-by-step explanation:

This is the answer because:

1) Solve for  x  by simplifying both sides of the equation, then isolating the variable.

Therefore, the answer is x = g + c

Step-by-step explanation:

1 plus 3 equals 4 plus 5 equals 9

Answer: b. 30%

Step-by-step explanation:

given data:

population size (n) = 100

A1 = 0.7

A2 = 0.3

if A1 and A2 are selectively neutral, the probability that A2 would drift to fixation

= 0.3

= 30%

there is a. 30% chance that A2 would drift towards fixation.

equation:55x+1

Answer:

Equation: 55 + B = A

Ammount amy earns if she sells 33 books: 88 dollars

Step-by-step explanation:

they let us know that she earns 55 dollars a week. this is the minimum she can earn in a week. So 55 is just 55. she cant earn more or less than 55 a week by just working there. the variable is the ammount of books she sells every week. Every book she sells gives her an extra one dollar to her overall wage per week. so 55 is the base and the one dollar per book is the variable that changes depending on how much she sold. So the equation would the base of 55 and the variable 1x (x being the ammount of books being sold and the 1 being how much money she makes from each book) and now just put them together with a plus sign and it would look like this

55 + 1x = ...

If she was to sell 33 books and shes earning 1 dollar per book 1(33), we only change the x from x to 33

55 + 1(33) which gives us 88

Answer:

Step-by-step explanation:

[tex]x =\frac{4-k}{6}[/tex]

Cross Multiply

[tex]x \times 6 = (4-k)\times 1\\\\6x = 4-k[/tex]

Isolate k

[tex]6x -4 =-k[/tex]

Divide through by -1

[tex]\frac{6x}{-1} -\frac{-4}{-1} = \frac{-k}{-1}\\ \\-6x+4 =k\\\\k =-6x+4[/tex]

Answer:

[tex]r-value = 0.99[/tex]

Step-by-step explanation:

Given

The list of options

Required

Which represents the strongest correlation.

When [tex]r-value > 0.7[/tex], it is considered to be strong.

Compare this condition with the given options, we're left with:

[tex]r-value = 0.73[/tex]

[tex]r-value = 0.99[/tex]

The above r-values show strong correlation.

However

[tex]r-value = 0.99[/tex] is stronger

because [tex]0.99 > 0.73[/tex]

Hence;

[tex]r-value = 0.99[/tex] answers the question

Answer:

The answer is 5.75

Step-by-step explanation:

I used desmos

Steps to solve:

-4(x - 2) + 5 = -10

~Distribute left side

-4x + 8 + 5 = -10

~Combine like terms

-4x + 13 = -10

~Subtract 13 to both sides

-4x = -23

~Divide -4 to both sides

x = 23/4

The correct answer is C. The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground.

Explanation:

Two key features of living organisms are energy processing and response to stimuli. These two features imply organisms require nutrients, which can be taken from the environment or created through a process such as photosynthesis and they sense their surroundings and respond to it.

Moreover, these two features are exemplified by mushroom (fungi) in the sentence "The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground" because the first section shows the developing mushroom takes nutrients from the soil or its environment and this is essential for growing and survival. Also, the second section of the sentence shows the developing mushroom can sense its environment and respond by developing only in appropriate conditions.

C

hope i helped ya

Answer:

x = -4

Step-by-step explanation:

3x -2(6-x) = 7x +2(5+x) -6

Distribute -2 through the parentheses 3x -12 +2x = 7x +2(5+x) -6

Distribute 2 through the parentheses 3x -12 +2x = 7x +10 +2x -6

3x -12 +2x = 7x +10 +2x -6 cancel equal terms on both sides of the equation

3x -12 = 7x +10 -6 subtract the numbers 3x -12 = 7x +4

                           Move variable to the left left handed side and change its sign

3x -7x-12 = 4   -->   3x -7x = 4 + 12  -->  -4x = 4+12  --> -4x = 16

             Divide both sides of the equation by -4  -->  x = -4

Answer:

a) 6x³ − 5x² − 39x + 35

b) no

Step-by-step explanation:

(2x − 5) (3x² + 5x − 7)

Distribute:

3x² (2x − 5) + 5x (2x − 5) − 7 (2x − 5)

Distribute again:

6x³ − 15x² + 10x² − 25x − 14x + 35

Combine like terms:

6x³ − 5x² − 39x + 35

5x − 2 is the opposite of 2x − 5, so you would get the negative of the answer from part (a).
