Solve the system of linear equations by substitution.<br><br> 4x−2y=14<br> y=12x−1
Alexus [3.1K]

Answer:

The answer is (-0.7, -9.4)

Step-by-step explanation:

1) Since we are using the substitution method, and we know that y = 2x-1, in the first equation, plug that into y.  It should look like this:

4x-2(12x-1) = 14

4x -24x + 2 = 14

2) Combine like terms and continue to simplify until you get a direct answer for each variable.

-20x + 2 = 14.

-20x = 12.

x = -7/10 (or -0.7)

3) Now we know what x equals, so to find our y-coordinate, we will plug this into either equation.

y = 12(-7/10) -1

y= -84/10 -1

y= -9.4

4) Now that we have our x value and y value, we know our point. The solution is (-0.7, -9.4).

KonstantinChe [14]

Answer:

V = 167.55 inches^3

Step-by-step explanation:

v =  \frac{1}{3} \pi {r}^{2}  \times h \\ v =  \frac{1}{3} (3.14) \times ( {4})^{2}  \times (10) \\ v = 167.55 \: \:  \:   {inches}^{3}

I hope that is useful for :)

Which graph best represents the solution to the system of equations shown below? y = -4x - 19 y = 2x − 1 A coordinate grid is sh
liraira [26]

Answer:

Option 3

A coordinate grid is shown from negative 10 to positive 10 on the x axis and also on the y axis. Two lines are shown intersecting on ordered pair negative 3, negative 7.

Step-by-step explanation:

y = -4x - 19 y = 2x − 1

-4x - 19 = 2x - 1

6x = -18

x = -3

y = 2(-3) - 1 = -7

Find the median of the data. <br><br> 24,74,61,29,38,27,68,54
Nataly_w [17]

Answer:

The median of the data is 46.

Step-by-step explanation:

Put the numbers in order so it would look like this.

24, 27, 29, 38, 54, 61, 68, 74

The ones in the middle would be the mean, however, there are two numbers in an even-number data, 38 and 54.

Add these two numbers together to get 92 and divide that number by 2 to get your median which is 46.
