-x+y= -1

6y= -24

-24÷6= -4

Answer:

Step-by-step explanation:

x + 5y = -23

5x - 5y =  5

6x = -18

x = -3

-3 + 5y = -23

Answer:

The number of muffins sold by the students is:

Step-by-step explanation:

First, we name the variables:

Now we establish the equations with the information given in the exercise:

We can use in this case the reduction method, to this, we multiply the first equation by (-0.5) obtaining the equation 3:

    3. -0.5C - 0.5M = -50

We operate the equations 2 and 3 to eliminate the variable C:

And we solve for the variable M:

We could stop here because we know the number of muffins now, but with the value for M, we can solve the value of C with the first equation to check the answer is correct:

In the end, we replace the values in the second equation and verify if the answer is correct:

Answer:

37.5

Step-by-step explanation:

if it decreases by 1/2 every 8 hours;

( 3×8= 24)

the first 8 hours 1/2×300 =150 gram

the second 8 hours(16 hours) = 1/2×150=75 gram

the third 8 hours(24 hours) = 1/2×75= 37.5gram

Answer:

C

Step-by-step explanation:

It's because Magnesium-27 is 8 hours which makes the 300/8=37.5

Answer:

from 30.48 till 53.34

Step-by-step explanation:

3.81×8=30.48

3.81×14=53.34

The range is 30.48 to 53.34

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

cost of gas with tax is $3.81 per gallon

But gas should be less than 14 gallons and not more than 8 gallons.

So,

=3.81×8

=30.48

3.81×14

=53.34

Hence, the range is 30.48 to 53.34,

Answer:

She will have $2792 at the end of her four year investment

Step-by-step explanation:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Gift of $2500:

This means that [tex]P = 2500[/tex]

She shopped around and found a 4 year GIC investment that earns 2.8% interest annually.

This means that [tex]t = 4, r = 0.028, n = 1[/tex].

How much will Anna have at the end of her four year investment?

This is A(4). So

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]A(4) = 2500(1 + 0.028)^{4} = 2792[/tex]

She will have $2792 at the end of her four year investment

Answer:

The slope of the line passing through (1, 2)  and (3, 8)  is:

Slope = 3

Step-by-step explanation:

Given the points

Here:

(x₁, y₁) = (1, 2)

(x₂, y₂) = (3, 8)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [8 - 2] / [3 - 1]

               = 6 / 2

               = 3

Thus, the slope of the line passing through (1, 2)  and (3, 8)  is:

Slope = 3

Answer:

  BC = 16 +12√3

Step-by-step explanation:

In the attached, we see that ∆ABE is a 30°-60°-90° triangle with AB the short side and BE the hypotenuse. Then BE = 2·AB = 12√3.

EC is the side opposite AD in parallelogram ADCE, so is the same length, 16.

The length BC is ...

  BC = EC +BE

 BC = 16 +12√3

Answer:

[tex]\displaystyle \large{y\prime = 2t \sin (2t) + 2t^2 \cos (2t)}[/tex]

Step-by-step explanation:

We are given a function:

[tex]\displaystyle \large{y = t^2 \sin (2t)}[/tex]

To differentiate a function, we are going to use the product rules since there are two functions which are t^2 and sin(2t) multiplying together.

From the product rules, [tex]\displaystyle \large{y = f(x)g(x) \to y\prime = f\prime (x) g(x)+f(x) g\prime (x)}[/tex]

Therefore, [tex]\displaystyle \large{y = t^2 \sin (2t) \to y\prime = (t^2)\prime \sin (2t) + t^2 (\sin (2t))\prime}[/tex]

Before we start differentiating, I’d like you to look at [sin(2t)]’. A function like this, you cannot just directly derive and answer. You need to use chain rules.

We know that, [tex]\displaystyle \large{y = \sin (x) \to y\prime = \cos (x)}[/tex] but what if the “x” is another function? Like sin(3x), sin(x^2) as examples. The insides are another function, can be expressed as fog(x) or gof(x) is composite function.

Basically, chain rule is a rule or formula for composite function and it’s the most common and useful as well as being always used in differentiation.

Chain Rules

[tex]\displaystyle \large{\frac{dy}{dx} = \frac{dy}{du} \frac{du}{dx}}[/tex]

where u is another function in a bracket. From the formula above, it can be also written as:

[tex]\displaystyle \large{[f(g(x))]\prime = f(g(x))\prime \cdot g(x)\prime[/tex]

To simply say, you differentiate the whole function first then multiply with the chain or inner derived function.

So from the function, we obtain:

[tex]\displaystyle \large{y\prime = 2t \sin (2t) + t^2 \cos (2t) \cdot (2t)\prime}\\ \displaystyle \large{y\prime = 2t \sin (2t) + t^2 \cos (2t) \cdot 2}\\ \displaystyle \large{y\prime = 2t \sin (2t) + 2t^2 \cos (2t)}[/tex]

The factored form would be:

[tex]\displaystyle \large{y\prime = 2t ( \sin (2t) + t \cos (2t))}[/tex]

From above, for polynomial function, to differentiate, you can do by using the power rules.

Power Rules

[tex]\displaystyle \large{y = ax^n \to y\prime = nax^{n-1}}[/tex]
