Answer:
y=6/5x-1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-7-5)/(-5-5)
m=-12/-10
simplify
m=6/5
y-y1=m(x-x1)
y-5=6/5(x-5)
y=6/5x-30/5+5
y=6/5x-6+5
y=6/5x-1
Answer:
1 apple= $0.4
Step-by-step explanation:
Let o=orange
Let a=apple
4o+5a=4
2o+3a=2.20
2o=2.20-3a
o=2.20-3a/2
Let's go balk to the the first equation
4o+5a=4
4(2.20-3a/2)+5a=4
4.4-6a+5a=4
4.4-a=4
-a=-0.4
a=0.4
Apple=$0.4
Answer:
A. 3x+50 ≤ 100; 16 people
Step-by-step explanation:
If x represents the number of people at Berta's party, then the cost of food is 3x. Added to the $50 cost of room rental, the total charge Berta must pay will be ...
3x +50
She wants this to be at most $100, so her inequality is ...
3x +50 ≤ 100
Berta can solve this by subtracting 50, then dividing by 3.
3x ≤ 50
x ≤ 16 2/3
Since x represents a number of <em>people</em>, and it is not possible (or desirable) to have 2/3 of a person show up, the maximum number of people that can attend Berta's party is 16.
A triangle adds up to 180 degrees so it would be 70

Answer:
Step-by-step explanation:
84/18<√x<√42
42/9<√x<√41
1764/81<x<41
21.777...<x<41
but x is an integer
22≤x≤40
or x∈[22,40]
or x=22,23,24,...,40
