Answer: x^2+y^2=7^2 (C)

Step-by-step explanation:

Alright, lets get started.

The standard equation of a circle is given by :

(x-h)^2 + (y-k)^2=r^2

Where (h,k) is the center of circle and r is the radius of circle.

As per given question, center should be origin, it means the center should be (h,k)=(0,0)

As per given question, radius should be 7, it means r=7

Plugging the value of (h,k) and r in standard equation of circle,

(x-0)^2+(y-0)^2=7^2

x^2+y^2=7^2 ...... Answer (C)

Hope it will help :)

Answer:

3/4 miles

Step-by-step explanation:

3 1/4 as a mixed fraction => 13/4

2 2/4 as a mixed fraction => 10/4

13/4 - 10/4 = 3/4

If anyone can help me to solve this.​
Sindrei [870]

Answer:

x + 96 = 90°

x + 89 = 80°

Step-by-step explanation:

<u>Consecutive Interior Angles Theorem</u>

When a transversal line intersects two parallel lines, it forms two pairs of consecutive angles on either side of the transversal line.  Each pair of consecutive interior angles are supplementary (sum to 180°).

<u>Question 1</u>

To find the measure of the angle, find the value of x by using the Consecutive Interior Angle Theorem:

⇒ (x + 96)° + (x + 96)° = 180°

⇒ x + 96 + x + 96 = 180

⇒ 2x + 192 = 180

⇒ 2x + 192 - 192 = 180 - 192

⇒ 2x = -12

⇒ 2x ÷ 2 = -12 ÷ 2

⇒ x = -6

Substitute the found value of x into the expression to find the measure of the angle indicated in bold:

⇒ x + 96 = -6 + 96 = 90°

<u>Question 2</u>

To find the measure of the angle, find the value of x by using the Consecutive Interior Angle Theorem:

⇒ (x + 109)° + (x + 89)° = 180°

⇒ x + 109 + x + 89 = 180

⇒ 2x + 198 = 180

⇒ 2x + 198 - 198 = 180 - 198

⇒ 2x = -18

⇒ 2x ÷ 2 = -18 ÷ 2

⇒ x = -9

Substitute the found value of x into the expression to find the measure of the angle indicated in bold:

⇒ x + 89 = -9 + 89 = 80°

y + 3 < 1

y - 3 + 3 < 1 -3

y < -2

2y +1 >= 5

2y - 1 + 1 <= 5 - 1

2y <= 4

2y/2 <= 4/2
