12x−39≤9 AND−4x+3<−6
Answer:
2 1/4 < x ≤ 4
Step-by-step explanation:
12x−39≤9 AND−4x+3<−6
Solve them separately and then put back together
12x−39≤9
Add 39 to each side
12x−39+39≤9+39
12x ≤48
Divide by 12
12x/12 ≤48/12
x ≤4
Now the other inequality
−4x+3<−6
Subtract 3 from each side
−4x+3-3<−6-3
-4x < -9
Divide by -4, remembering to flip the inequality
-4x/-4 > -9/-4
x > 2 1/4
put back together
x > 2 1/4 and x ≤4
2 1/4 < x ≤ 4
Answer:
2.25<x≤4
Step-by-step explanation:
12x−39≤9 ⇒ 12x≤ 48 ⇒ x≤4
−4x+3<−6 ⇒ -4x < -9 ⇒ x> 9/4= 2.25
2.25<x≤4
or
x= (2.25, 4]

How much would you pay for a boat that
costs $15,000 if you buy it on sale for
15% off (excluding tax)?
Answer:
$12,750
Step-by-step explanation:
15% of 15,000 is 2,250 and you find this by multiplying the discount and the total. Then you subtract the discount from the original price to know the discounted price.
15,000-2,250=12,750
So you'd pay $12,750 without taxes
Answer:
The cost of the boat after the sale would be 12,750. (excluding tax)

What is the sum? 2/x^2+4/x^2
Answer:
\frac{2}{ x^{2} } + \frac{4}{ x^{2} } = \frac{2+4}{ x^{2}}= \frac{6}{ x^{2} }
Step-by-step explanation:
When we add two expression in fraction we take Least common multiple of two expression in the denominator
Here we have expression
Now, we write a common denominator
rewrite the expression
Now, we combine the numerator 2+4 is equal to 6
So, we will get = \frac{2}{x^{2}}+ \frac{4}{x^{2}} =\frac{6}{x^{2} }
Hope this helps!
Which equation represents a line which is parallel to y = 0?
A. y = 6
B. x = -5
C. y = x
D. y = x - 1
Answer:
A. y = 6
Step-by-step explanation:
Y= 0 is equation of x - axis
equation of any straight line which is parallel to x-axis and at distance of a from it is given y = c.
Therefore, from the given option only option A y =6 is in form of y = a and hence is the correct answer.
_______________________________________
Also we know that for two lines to be parallel , their slope should be equal.
slope of line y = mx + c is m
slope of y = 0 here m = 0, hence slope is 0
out of the given option
only for y - 6 slope is 0 and hence it is the correct answer.

The following data points represent the number of hours each of the staff members at Daniel's Department Store slept on Thanksgiving night.
Sort the data from least to greatest.
Find the interquartile range (IQR) of the data set.
Answer:
3 hours
data from least to Greatest:
2.6, 3 , 4.9 , 5 , 5 , 6 , 6 , 7.9 , 8 , 8.2
Step-by-step explanation:
I got it from Khan Academy
The interquartile range (IQR) of the data set is 3.
The given data set is 5, 8.2, 6, 7.9, 5, 2.6, 3, 4.9, 6 and 8.
We need to find the interquartile range (IQR) of the data set.
How to find the interquartile range (IQR) of the data set?To find the interquartile range (IQR), first, find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
Now, the order of data from least to greatest is 2.6, 3, 4.9, 5, 5, 6, 6, 7.9, 8, 8.2.
Q1=4.9 and Q3=7.9
So, IQR=Q3-Q1
=7.9-4.9=3
Therefore, the interquartile range (IQR) of the data set is 3.

F(9) if f(x) = x - 8
Answer:
f(9)=1
Step-by-step explanation:
This questions asks us to find f(9).
It is asking us to find what f(x), or y is, when x is equal to 9.
f(x)=x-8
Therefore, we can substitute 9 in for every x.
f(9)=9-8
Subtract 8 from 9
f(9)=1
If f(x)=x-8, then f(9)=1
Answer:
f(9)=1
Step-by-step explanation:
f(x)=x-8
plug in 9for x
f(9)=9-8
9-8 =1
Simon used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 time
Color of Marble Number of Times Rolled
Blue
15
Green
19
Yellow
16
Heads Tails
26 24
Using Simon's simulation, what is the probability of pulling a blue marble and the coin landing
39
50
Answer:
360/2500
Step-by-step explanation:
the blue marble is 15 times out of 50 = 15/50 reduces to 3/10
landing on tails is 24 out of 50 = 24/50 reduces to 12/25
to find the probability of both multiply together:
3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250
if you multiplied the numerator and denominator by 10 you get 360/2500.
the answer is 360/2500
Answer:
360/2500
