Answer:
A. 55
Step-by-step explanation:
Answer:
= 1/4
Step-by-step explanation:
We can find the slope given two points by using the following formula
m = (y2-y1)/(x2-x1)
= (-4 - -2)/(-4 -4)
= (-4+2)/(-4-4)
= -2/-8
= 1/4

Answer: 9 units</h3>
===================================================
Explanation:
Let's calculate the volume of one small spherical bead
V = (4/3)*pi*r^3
V = (4/3)*pi*3^3
V = 36pi
The volume of 27 such identical beads is 27*36pi = 972pi cubic units.
----------
This is the new volume and we'll use this to find the radius r of the larger sphere.
V = (4/3)*pi*r^3
972pi = (4/3)*pi*r^3
3*972pi = 4pi*r^3
2916pi = 4pi*r^3
r^3 = (2916pi)/(4pi)
r^3 = 729
r = (729)^(1/3)
r = 9 units is the radius of the larger gold sphere
9 * x = 9x
9 * 5 = 45
9 * 8y = 40y
9x + 45 + 40y
9x + 40y + 45
Answer:
Linear
Step-by-step explanation:
When you graph them, they do not hit each other.
Linear equation in standard form is Ax+By=C
If it is in this form it is linear.
