Answer:

(1,3)

Step-by-step explanation:

y = 2x+1

y = 4x-1

Since both equations are equal to y, we can set them equal to each other

2x+1 = 4x-1

Subtract 2x from each side

2x+1-2x = 4x-2x-1

1 = 2x-1

Add 1 to each side

1+1 = 2x-1+1

2 = 2x

Divide each side by 2

2/2 = 2x/2

1 =x

Now we need to find y

y = 2x+1

y = 2(1)+1

y =3

In trapezoid ABCD, find m∠A if m∠B= 25°, m∠C = 155° and m∠ D= 117°.

telo118 [61]

Hello there! A trapezoid is a quadrilateral, and the angles of a quadrilateral have a sum of 360°. We don't know the angle measurement for A, so let's start off by adding the measurements of the other angles together. 117 + 155 + 25 is 297. Now, we subtract that number from 360 to find the angle measurement. 360 - 297 is 63. There. The measurement of angle A is 63°.

$x^2$

Step-by-step explanation:

$x > 0~\text{means that x is positive number.}$

Suppose you draw a card from a well-shuffled deck of 52 cards. Find each of the following odds.

garik1379 [7]

1) number of cards that aren't : number of cards that are 3
we have 48 cards that arent 3 and 4 cards that are. that means that odds are:
12:1 of not drawing 3

2) fallow same logic. its just opposite.
1:12

3) same logic. but there are only 2 black 7 cards which means that odds are:
50:2 or
25:1

4) opposite of previous.
1:25
