Hello from MrBillDoesMath!
Answer:
(1/3) x <= -6 when x >= 18
Discussion:
Solve the inequality:
-(1/3)x < = -6
Add +(1/3)x and + 6 to both sides:
- (1/3)x + (1/3x) + 6 <= -6 + (1/3)x + 6 =>
0 + 6 <= (1/3)x => (multiply both sides by 3)
6*3 <= 3 (1/3) x =>
18 <= x

Answer:
The required point is P(-7,) where, x-coordinate twice the y-coordinate on line 2x - 6y = 7
Step-by-step explanation:
Given equation of line is 2x-6y=7
To find point on graph whose x-coordinate twice the y-coordinate:
Let y be y-coordinate of point
Hence, x-coordinate of point will be 2y
The required point is P(2y,y) on equation of line 2x-6y=7
Now,
2x-6y=7
2(2y)-6y=7
-2y=7
y=
Thus,
The required point is P(-7,)
Note: Figure show equation of line red line and point P as blue dot.

Answer:
No
Step-by-step explanation:
The table shows two differnt outputs for the number 7 which isn't how a function works so the answer is no
Find the number of eggs in 7 crates:
1 crate = 12 eggs
7 crates = 12 x 7 = 84 eggs
Add the 8 eggs in their fridge:
84 + 8 = 92 eggs
