Answer:
B
Step-by-step explanation
add all numbers then divide by the number of numbers and you get the means
Answer: True, because if a number is a whole number, for instance, it must also be an integer and a rational.
I would so go with B I'm not sure if that's the correct answer though but that's what I would go with
If you use a calculator its easy
16.72 - 1.24 = 15.48
15.48 divided by 12 is 1.29
for sales tax 1.24 divided by 12 is .10
so for each one She spent $1.39
Answer:
y - 2 = (-3/7)(x + 5)
Step-by-step explanation:
Recall that the slopes of a line and another line perpendicular to the first are negative reciprocals.
The slope of the given line is 7/3. The negative reciprocal of that is -3/7. Thus, we immediately eliminate the fourth answer choice.
We must now find the equation of the perpendicular line, with slope -3/7, that passes through (-5, 2). We'll do that using the point-slope formula for the equation of a straight line.
That formula is y - k = m(x - h), where m is the slope and (h, k) is the given point.
Substituting 2 for k, -5 for h and -3/7 for m, we get:
y - 2 = (-3/7)(x + 5). This matches the 3rd given possible answer.
