B is the correct answer :)
Your equation is:
(x + 2)² + (y - 1)² = 9
Option A is your answer.
First you multiply 3 times x and 3 times 2
4(3(x + 2) -1) =50
and get
4( 3x +6 -1) =50
then you add 6 plus -1
4 ( 3x +5) = 50
then multiply 4 times 3x and 4 times 5
12x +20 = 50 and subtract 20 from both sides
-20 -20
and you will get
12x = 30
divided both sides by 12
12x/12 = 30/12
then you find the ones that are the same amount in decimals but are smaller
and that's your answer: x= 5/2
hope you get it!!!
Answer:
47°
Step-by-step explanation:
In the picture attached, the problem is shown.
When two secants intersect at a point, the angle made is one-half of the difference between the greater arc and the minor arc formed. In this case:
∠ABC = 1/2*(arc DE - arc AC)
Replacing with data from the picture:
∠ABC = 1/2*(142° - 48°)
∠ABC = 47°
1)x+1/2x-1=46
2) The length is 94/3(or 31 1/3) and the width is 44/3(or 14 2/3)
