Answer:

2a. One Solution

2b. Infinite Solutions

2c. No Solution

Step-by-step explanation:

In all the problems club terms with x on one side and the constants on the other side.

2a. 6x + 4x - 6 = 24 + 9x

⇒ 10x - 6 = 24 + 9x

Subtracting 9x and adding 6 on both sides;

⇒ 10x - 9x = 24 + 6

⇒ x = 30

The only possible value of x that could satisfy the equation is 30. So, there is only one possible solution to the equation.

2b. 25 - 4x = 15 - 3x + 10 - x

Clubbing like terms;

25 - 15 - 10 = 4x - 3x - x

⇒ 25 - 25 = 4x - 4x

⇒ 0 = 0

Note that any value of 'x' could satisfy this equation. So, there are infinite solutions to the equation.

2c. 4x + 8 = 2x + 7 + 2x - 20

⇒ 4x - 2x - 2x = - 20 + 7 + 8

⇒ 4x - 4x = -5

⇒ 0 = -5

This is absurd. No value of 'x'  can satisfy this. So, there are no solutions to this equation.

Answer:

If Mia wants to use 6 cups of rice, she would need to multiply the amount of each ingredient by 3, because the original 2 cups times 3 is the 6 cups she wants to use. So the new amount for the recipe would be this:

6 cups of rice

12 cups of milk  

1 cup of sugar  

3 handful of raisins

3 cinnamon sticks

When asking how many this will serve, we also multiply by 3 the original amount of people which is 4 to get 12 servings of Arroz con leche

Click here please. The problems are in picture format
padilas [110]

First picture:

You got the first two right (good job!), so I'll just tackle the third one. If you have to compute f(x-4), it means that you have to substitute x-4 in place of x. Differently from the first two points, this will generate a new function, rather than a specific value:

f(x) = \sqrt{x+4}+2 \implies f(x-4) = \sqrt{(x-4)+4}+2 = \sqrt{x}+2

Second picture:

Given the point (x,y) highlighted in the picture, you can deduce that the base is 2x units long (since it spans from (-x,0) to (x,0)) and the height is y units long (because it spans from (x,0) to (x,y)). So, the area of the rectangle is the multiplication between base and height:

A = 2xy

But we know that y=f(x)=\sqrt{36-x^2}, so we have

A = 2x\sqrt{36-x^2}

The domain of this function is given by the domain of the square root: we want its argument to be non, negative, so we have

36-x^2 \geq 0 \iff x^2 \leq 36 \iff -6 \leq x \leq 6

But since the problem is symmetric, the answer is

0 \leq x \leq 6

You can only see the answer 0 < x < 6 because, if you choose x=0 or x=6, the rectangle degenerates to a segment, and your exercise doesn't like this scenario, apparently

Linda and Rob open an online savings account that has a 2.89% annual interest rate, compounded
sp2606 [1]

Answer:

FV= $34,222.33

Step-by-step explanation:

<u>First, we need to calculate the weekly interest rate:</u>

Weekly interest rate= 0.0289/52= 0.00056

<u>To calculate the future value (FV), we need to use the following formula:</u>

FV= {A*[(1+i)^n-1]}/i

A= weekly deposit

n= 15*52= 780

A= $35

FV= {35*[(1.00056^780) - 1]} / 0.00056

FV= $34,222.33
