Answer:
Point B
Step-by-step explanation:
In a pair representation of a point first element refers to X axis and the second refers to Y axis.
1. find x = 2 on X axis (horizontal axis)
2. draw a vertical line passing x = 2
3. find y = -4 on Y axis (vertical axis)
4. draw a horizontal line passing y = -4
5. Where the 2 drawn lines are cross is the answer
138 miles just divide miles for 4 gal. by 4 then multiply that number by 6
HERE THE EQUATION IS
=> d = 5x+ 5y
=> d = 5(x+y)
Divinding both side by 5
=> d/ 5 = x+y
=> d/5-x = y
=> y = (d- 5x)/5
So the THIRD option is right for your question.
Answer:
x^2 + y^2 = 49
Step-by-step explanation:
The equation of a circle is given by
( x-h) ^2 + (y-k) ^2 = r^2
(h,k) is the center of the circle and r is the radius
The circle is centered and (0,0) and the radius is 7
( x-0) ^2 + (y-0) ^2 = 7^2
x^2 + y^2 = 49
-18x-17=-53 /add 17 to both sides
-18x-17+17=-53+17
-18x=-36
x=(-36)/(-18)
x=2
