Answer:
No
Step-by-step explanation:
take the example of 19. it is a prime number but when flipped gives 91, divisible by 7 and 13, therefore not prime. The examples in the question were just carefully selected to be true.
Answer:
< 2 and < 6
< 3 and < 7
>> Corresponding angles are the pairs of angles that are found in the same relative position on different intersections.
Answer:
y = -5x - 8
Step-by-step explanation:
Take the points (-5,-4) and (0,-3) plug them into this formula to get the slope.

Now plug in your points

Since you're slope is 1/5 the slope of the perpendicular line is going to be the totally opposite -5 is the slope of the perpendicular line.
Now plug in -5 and the point (-2,2) into y = mx + b to get the y-intercept
2 = -5(-2) + b (b represents the y-intercept)
2 = 10 + b (subtract 10 from both sides)
-8 = b
The perpendicular line looks like this y = -5x - 8

Answer:
1. The equation would be y = -2x + 9
Step-by-step explanation:
To find the line parallel going through the given point, first note that parallel lines have the same slope. This means that in #1, we have a slope of -2 in the original line, therefore the parallel line will also have a slope of -2. Now we can use this and the given point to find the line using point-slope form.
y - y1 = m(x - x1)
y - 1 = -2(x - 4)
y - 1 = -2x + 8
y = -2x + 9
Answer:
A.) .75
Step-by-step explanation:
So the upper quartile is basically just the median of the bottom half. So we take the bottom half of the numbers:
0.5, 0.5, 0.75, 0.75, 1, 1, 1
And the median of the is 0.75
So the lower quartile is .75
hope this helps:)
