Answer:
3y + 4
Hope This Helps :)
The standard for of this equation is x – y = 0
Firstly, options A and D are not in standard form, so they are not options.
To decided between B and C, we choose a point on the line and see if it works. For example, we'll use (2, 2).
x – y = 0
2 - 2 = 0
0 = 0
This is true for option C. Therefore, it is correct.
Answer:
Fred = 26, Natalie = 15
Step-by-step explanation:
N + F= 41 // N = 41 - F (eqn 1)
4N + F = 86 (eqn 2)
sub eqn 1 into eqn 2
4(41 - F) + F = 86
164 - 4F + F = 86
-3F = - 78
F = 26
sub F = 26 into eqn 1
N = 41 - F
N = 41 - 26
N = 15
Since the sphere is located at the center and has radius 5.
Out of the following given points,
(5,5,-5) will lie on the sphere, where x and y coordinates will be positive and z coordinate will be negative.
This is because the radius of the circle is 5 units.
