Answer:

C

Step-by-step explanation:

If you multiply the top equation by 2 and the bottom equation by -5, then there will be a 10x in the first equation and a -10x in the second, which you can cancel out in the next step. Therefore, the correct answer choice is C. Hope this helps!

To eliminate x, we need to make the coefficient of x the same in both equations. We achieve this by multiplying Equation I and Equation II by certain numbers. Subtraction of the modified equations then eliminates x, leaving one equation with y.

To eliminate the variable x in the system of equations, we need to multiply each equation by a number that would make the coefficients of x in both equations equal, such that they cancel each other out when we add or subtract the equations.

For the given equations: Equation I: 5x + 3y = 19 and Equation II: 2x - 4y = -8, we can multiply Equation I by 2 and Equation II by 5.

This will result in:

Equation I: 10x + 6y = 38 and Equation II: 10x - 20y = -40

By subtracting Equation II from Equation I, we are able to eliminate the x variable, resulting in the equation 26y = 78.

Answer:

For the first one q is 134

And the second one is t is 8.8

Step-by-step explanation:

That is true cause 134 +166 = 300

and, 14.2 = 8.8 - 5.4.

Please Mark brainliest!

For the equations given, the value of q is found to be 134 after subtracting 166 from both sides, and the value of t is calculated as 19.6 by adding 5.4 to both sides.

To solve the first equation, q + 166 = 300, we need to isolate the variable q by subtracting 166 from both sides of the equation:

q + 166 - 166 = 300 - 166

q = 134

So, the value of q is 134.

For the second equation, 14.2 = t - 5.4, we need to isolate the variable t by adding 5.4 to both sides of the equation:

14.2 + 5.4 = t - 5.4 + 5.4

t = 19.6

Thus, the value of t is 19.6.

First, let's rearrange the first equation so we can know what y equals to.

So, (x - y = 2) becomes (y = x - 2).

Now, we can plug this into the second equation so we can find x.

6x + 4(x - 2) = 92

6x + 4x - 8 = 92

10x - 8 = 92

10x = 100

x = 10

Now that we know x equals 50, we can plug this into either equations to find y. Let's use the first equation.

10 - y = 2

-y = -8

y = 8

Now, let's check our work by plugging int eh values of x and y for both equations.

First equation:

10 - 8 = 2

Second equation:

6(10) + 4(8) = 92

60 + 32 = 92

So, the values of x and y are correct.

Answer:

m = 3/4

Step-by-step explanation:

12.6+4m=9.6+8m

Isolate the variable, m. Note the equal sign, what you do to one side, you do to the other.

Subtract 4m and 9.6 from both sides:

12.6 (-9.6) + 4m (-4m) = 9.6 (-9.6) + 8m (-4m)

12.6 - 9.6 = 8m - 4m

Simplify:

12.6 - 9.6 = 8m - 4m

3 = 4m

Isolate the variable, m. Divide 4 from both sides:

4m = 3

(4m)/4 = (3)/4

m = 3/4

3/4 is your answer for m.

~

Answer:

3/4 =m

Step-by-step explanation:

12.6+4m=9.6+8m

Subtract 4m from each side

12.6+4m-4m =9.6+8m-4m

12.6 = 9.6 +4m

Subtract 9.6 from each side

12.6 - 9.6 = 9.6 - 9.6 +4m

3 = 4m

Divide each side by 4

3/4 = 4m/4

3/4 =m

after 10 seconds  the charge  is 1.624

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one.

The electrical charge on a metal plate is given  by the function below, where t is the time in  seconds. What is the charge after 10 seconds?

C (t) = 12[tex]e^{\frac{-t}{5} }[/tex]

My answer:

Given the information:

C (t) = 12[tex]e^{\frac{-t}{5} }[/tex]  

when t =10 we have:

C (10) = 12[tex]e^{\frac{-10}{5} }[/tex]

<=>  C (10) = 12[tex]e^{-2}[/tex]

<=>  C (10) = 12[tex]\frac{1}{e^{2} }[/tex]

<=> C (10) = 12 * 0.1353

<=>  C (10) = 1.624

Hence, after 10 seconds  the charge  is 1.624

Answer:

0.8415 :)

Step-by-step explanation:

To find the product of 5.61 and 0.15, multiply the two numbers to get 2805 and then place the decimal to account for a total of four decimal places in both numbers, resulting in a product of 0.8415.

The product of 5.61 and 0.15 is calculated by simply multiplying the two numbers together. To do this, you can line up the numbers as you would in any multiplication problem, making sure to pay attention to the decimal places:

Since there are two decimal places in each number we are multiplying (two in 5.61 and two in 0.15), we need to have a total of four decimal places in the answer. Taking the raw multiplication result of 2805 and inserting the decimal correctly, we get the final answer:

Therefore, the product of 5.61 and 0.15 is 0.8415.

Answer:

A) an upper quartile of 56 and a median of 50

Step-by-step explanation:

Hello!

The lower and upper ends "box" from the box and whiskers plot is determined by the first (Q₁) and third (Q₃) quartiles of the data set and the line inside the box marks the median or second quartile of the sample (Q₂)

The length of the whiskers of the diagram is determined by the minimum value (left whisker) and the maximum value (right whisker)

If you observe the graphic:

Q₁= 42

Q₂= 50 (Median)

Q₃= 56

Min= 38

Max= 66

The box is delimited by a lower quartile of 42 and an upper quartile of 56, with a median 50, the least observation is 38 and the highest observation is 66.

The correct choice is A.

Answer: $786

Step-by-step explanation:

first hour = $50

Second hour = $60

Third hour = $72

Total amount after 24 hours :

4th hour = 72 + 1 4 = 86

5th = 86 + 16 = 102

6th = 102 + 18 = 120

7 = 120 + 20 = 140

8 = 140 + 22 = 162

9 = 162 + 24 = 186

10 = 186 + 26 = 212

11 = 212 + 28 = 240

12 = 240 + 30 = 270

13 = 270 + 32 = 302

14 = 302 + 34 = 336

15 = 336 + 36 = 372

16 = 372 + 38 = 410

17 = 410 + 40 = 450

18 = 450 + 42 = 492

19 = 492 + 44 = 536

20 = 536 + 46 = 582

21 = 582 + 48 = 630

22 = 630 + 50 = 680

23 = 680 + 52 = 732

24 = 732 + 54 = 786

Coefficient of a² is -2

Coefficient of ab is 4

Coefficient of b is -2
