-8x + 3y = -33
y = -5x + 35

Answers

Answer 1

Answer:

x = 6  y = 5

Step-by-step explanation:

-8x + 3y = -33

y = -5x +35

-8x + 3(-5x + 35) = -33

-8x - 15x + 105 = -33

-23x + 105 = -33

-23x = -138

x = 6

-8(6) + 3y = -33

-48 + 3y = -33

3y = 15

y = 5

Determine the measures of the angles if they are both vertical and supplementary.

Answers

Answer:

90, 90

Step-by-step explanation:

Since the two angles are vertical, it means that they must have the same measure. Because they are supplementary, that means they add to 180. Thus, the two angles must be 90 and 90.

An urn contain 2 white marbles, 3 green marbles, and 5 red marbles. A marble is drawn and then replaced. Then a second marble is drawn. What is probability that the first marble was white and the second was green?

Answers

Answer:

1/5

Step-by-step explanation:

To find this you would need to multiply the probability of pulling a white marble to the probability of pulling out a green marble.

1)First you would need the probability of pulling out a white marble. There are 10 marbles in total and out of those 2 are white. So the probability of pulling out a white marble would be 2/10. If you simplify that you would get 1/5 for the probability of pulling out a white marble.

2)Next, you would find the probability of pulling out a green marble. Using the same process that we used to find the probability of pulling out a white marble, we would find the answer to be 3/10. All that we did here was green marbles/total marbles. By filling that in we got 3/10 for the probability of pulling out a green marble.

3)Now all that is left is doing probability of pulling a white marble × probability of pulling out a green marble. This would be 1/5 × 3/10. After solving the answer would be 3/15 which we would simplify down to 1/5 as our final answer.

the following graph shows the number of soccer games a team won in each of their three seasons. Explain how you could redraw the graph so the change in wins between the three seasons does not seem so great.

Answers

Answer:

you can instead draw a 4x3 graph, and just shrink the width to make it look like there was a bigger dip in between seasons. so season 1 would be under the first box, the second season under the second box, and the third season under the third box. this would then make the slope downward to therefore make the graph look like a bigger drop

C. 6

Step-by-step explanation:

So it says read less thann 25 books --> that means the numbers are 13,14,14,16,19,21,21,22,23, and 24 --> a total of 10 numbers

Then it says read more than 35 books --> that means the numbers are 37,41,42,43 --> a total of 4 numbers

Now, it says how many more --> that means you subtract 4 by 10 = 10 - 4 = 6

Therefore the answer is 6 more students read less than 25 books than read more than 35 books.

C. 6

So it says read less thann 25 books --> that means the numbers are 13,14,14,16,19,21,21,22,23, and 24 --> a

total of 10 numbers

Then it says read more than 35 books that means the numbers are 37,41,42,43 -- > a total of 4 numbers

Now, it says how many more --> that means you subtract 4 by 10 10 -4 = 6

Therefore the answer is 6 more students read less than 25 books than read more than 35 books.

Which is NOT a line of symmetry (please help)

Answers

Answer:

3

Step-by-step explanation:

The line 3 is not a line of symmetry.

What is Line of Symmetry?

Line of symmetry of a figure or a shape is the line which divides the figure or shape in to equal and symmetrical parts.

This line is also called as axis of symmetry.

It is sometimes also called as mirror line since the line divides in to parts which looks like mirror images.

Given is a shape of a triangle.

There are 4 lines drawn.

Of these, 3 lines are drawn from a vertex of the triangle to the middle point of the opposite side, which divides the triangle in to two equal triangles.

So these lines are lines of symmetry.

But line 3 does not divide the triangle in to equal parts.

So it is not line of symmetry.

Hence line 3 is not a line of symmetry.
