Answer: 3/11, 6/19/, 1/3, 5,8
Hope this helps
Step-by-step explanation:
Add 3 on both sides: 2I5-2xI≤18
divide 2 on both sides: I5-2xI≤9
-9≤5-2x≤9
subtract 5: -14≤-2x≤4
divide by -2. Remember: when divided by a negative number, the inequality symbol changes direction. so we have7 ≥x≥-2
rewrite it: -2≤x≤7
so the answer is C
you were right.
Do you remember how to find the equation of a line when you know two points on the line ? Well, that little table gives you FIVE points on the line, and in case some students didn't notice that, the table even labels the columns 'x' and 'y' as a hint. With 5 points given, there are 20 different ways to find the equation of the line. Get to work.
By definition, the ratio is the expression that would allow us to express the quotient of two numbers and/or any mathematical expressions. Let us take for example, numbers 4 and 5. The ratio between these values is 4/5.
The statement given above, "A ratio is a rate" is only sometimes true. This is only true when the unit of measurement of the denominator is in terms of time (seconds, minutes, hours, years, etc) because this would tell us how fast is something being done, consumed, etc. Example, the speed or rate of a car is 4 meters / 5 seconds.
Based on the graph, the slope is -3, and the y-intercept is 1. So your equation should be:
y = -3x + 1
The answer is C
y + 2 = -3(x - 1)
y + 2 = -3x + 3
y = -3x + 1
