Answer:
x = 1
y = -5
Step-by-step explanation:
In this question, we need to find what the values of "x" and "y" are.
To do this, we must solve the equations.
Solve:
6x + 2y = -4
3x + 4y = -17
Lets solve for "y" first:
6x + 2y = -4
-2(3x + 4y = -17) = -6x - 8y = 34
Now subtract the two equations from each other.
6x + 2y = -4
-6x - 8y = 34
-6y = 30
Divide both sides by -6
y = -5
Now, we know that the "y" variable's value is -5.
Lets find the value of "x" by plugging -5 to "y" in one of the equations:
6x + 2(-5) = -4
6x - 10 = -4
Add 10 to both sides.
6x = 6
Divide both sides by 6.
x = 1
The value of "x" is 1.
Answer: he has 128 + d
Step-by-step explanation:
well if he had 128 yesterday and today he got d more just add d to 128 and ull see
for example, lets say d = 16
to find out the total we woukd have to add 16 to 128 (just an example the answer is not d=16)
answer= 128+d
2x - y = 0
2x = y
3x - 2(2x) = -3
3x - 4x = -3
-x = -3
x = 3
2(3) = y
6 = y
Answer:
D
Step-by-step explanation:
You basically just add the numbers where x is. I tried it with 5 and both equalled 28. Using 5 as x makes the equation equal which is what we are looking for. So the answer is x=5.
To make a box and whisker plot, first you write down all of the numbers from least to greatest.
0, 1, 3, 4, 7, 8, 10
The median is 4, so that’s the middle line of the plot.
So now we have:
0, 1, 3, [4,] 7, 8, 10
So next we have to find the 1st and 3rd interquartiles..
0, [1,] 3, [4,] 7, [8,] 10
Those are the next 2 points you put on the plot.
Lastly, the upper and lower extremes. These are the highest and lowest numbers in the data.
[0,] 1, 3, 4, 7, 8, [10]
These are the final points on the plot.
To make the box of a box-and-whisker plot, you plot the 3 Medians of the data: 1, 4, and 8, and connect those to make a box that has a line in the middle at 4.
Next, you plot the upper and lower extremes: 0 and 10, by making “whiskers” that connect to the box. So you draw a line from the extremes to the box.
