Answer:
Step-by-step explanation:
3x-7 ≤ 14
3x≤ 14+7
3x≤ 21
x≤ 21/3 = 7
=> x = (-∞;7]
That means that x can be any negative number and any positivi number (1,2,3...7)
Answer:
D. -4
Step-by-step explanation:
All you have to do is make ratios so in class 701 you have to do chicken nuggets to pasta then chicken nuggets to the total then pasta to the total so the first class would be 5:6,6:11,and 5:11
Answer: 
Step-by-step explanation:
For this exercise you need to find the Least Common Multiple (LCM).
The steps two find the Least Common Multiple are shown below:
1. Descompose the numbers into their prime factors.
2. Multiply the commons an non commons with the highest exponent. The product obtained will be the Least Common Multiple.
Knowing this, you can find the Least Common Multiple between 7 and 11. This is:
Therefore the smallest number of biscuits each must have baked is:
Answer:
Equation of line shown in the graph is : x= - 2
Step-by-step explanation:
Given,
a line passing through two points ( -2,2) and ( -2,-3).
We need to use two pint line equation:
y - y1 = (y2 - y1 / x2 - x1 ) (x - x1 )
Here , x1 = -2 ,x2 = -2 , y1 = 2 and y2 = -3
So we can plug corresponding values in the line equation.
We get: y - 2 = {(-3 - 2) / ( -2 - (-2))} (x - (-2))
y - 2 = (-5 /0 ) (x + 2)
0 * (y - 2) = -5 (x+2)
0 = -5x - 10
10 = -5x
x = -10/5 = -2
Hence x= -2 is the equation of line shown in the graph.
