Find the equation of a line perpendicular to -3x + y=-5 that contains the point (1,4). Write the equation in slope.
Answer:
y = -1/3x + 13/3
Step-by-step explanation:
-3x + y=-5
y = 3x -5
Slope of perpendicular line is the opposite inverse so 3 becomes -1/3.
y-intercept going through point (1, 4):
y = mx + b
4 = -1/3(1) + b
4 = -1/3 + b
b = 13/3
Perpendicular equation of a line:
y = mx + b
y = -1/3x + 13/3
Jane Little rents a car for $39.00 a week. She pays $15.00 per week for the insurance, and spends $17.50 weekly on gas. What will her cost be per month (four weeks)?
Answer: Her cost will be $286 per month.
Step-by-step explanation: $39.00 times 4 is $156. $15.00 times 4 is $60. And $17.50 times 4 is $70. Adding all that together is $286
Answer:
$286.00
Step-by-step explanation:
First, you add 39.00 + 15.00 + 17.00 because that is for one week and you get $71.50 Then, you multiply 71.50 x 4 because there are 4 weeks in a month and you get $286.00 Hope This Helps :)

Answer:
Step-by-step explanation:
1.5x + 6 - 3= 4.5x - 9
1.5x + 3 = 4.5x - 9
Bringing like terms on one side
3 + 9 = 4.5x - 1.5x

-18 - 6n= 6 (1 + 3n)
Answer:-1
Step-by-step explanation:-18-6n = 6 + 18n
-6n=6
divide
n=-1
Answer:
-1
Step-by-step explanation:
First, divide by 6
-18/6- 6n/6=6/6(1+3n)
-3-n= 1+3n
Then move the variable to one side
-3-n+n= 1+3n+n
-3=1+4n
Then isolate the variable
-3-1=1-1+4n
-4=4n
Isolate more
-4/4=4n

One fruit drink advertised that it contained "10% real fruit juice." In one bottle, this was found to be 4.8 oz of real juice. How many ounces is something other than fruit juice?
Answer:
43.2 oz
Step-by-step explanation:
4.8/x=10/100
simplify:
4.8/x=1/10
cross multiply:
x=48
there is 48 oz juice in total
to find the rest:
48-4.8=43.2
43.2 oz is something other than fruit juice.

The household incomes for 10 different households are shown. What is the mean absolute deviation for the group (round to the nearest tenth)?
A) 6.4
B) 12.7
C) 15.2
D) 52.2
Answer:
d
Step-by-step explanation:
add all together equals 522
522/10 = 52.2
The mean absolute deviation of the data set of 15.2
What is mean absolute deviation?Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean.
Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.
Given is a data set, we need to find the mean absolute deviation for the group,
So,
The mean = 38+45+76+93+50+54+29+44+62+31 / 10
= 522/10 = 52.2
Now finding the absolute deviation =
|52.2-38| = 14.2
|52.2-45| = 7.2
|52.2-76| = 23.8
|52.2-93| = 40.8
|52.2-50| = 2.2
|52.2-54| = 1.8
|52.2-29| = 23.2
|52.2-44| = 8.2
|52.2-62| = 9.8
|52.2-31| = 21.2
The mean absolute deviation = 14.2 + 7.2 + 23.8 + 40.8 + 2.2 + 1.8 + 23.2 + 8.2 + 9.8 + 21.2 / 10
= 152.4 / 10
= 15.24
≈ 15.2
Hence, the mean absolute deviation of the data set of 15.2

How do you do this question?
Answer:
a) -7/9
b) 16 / (n² + 15n + 56)
c) 1
Step-by-step explanation:
When n = 1, there is only one term in the series, so a₁ = s₁.
a₁ = (1 − 8) / (1 + 8)
a₁ = -7/9
The sum of the first n terms is equal to the sum of the first n−1 terms plus the nth term.
sₙ = sₙ₋₁ + aₙ
(n − 8) / (n + 8) = (n − 1 − 8) / (n − 1 + 8) + aₙ
(n − 8) / (n + 8) = (n − 9) / (n + 7) + aₙ
aₙ = (n − 8) / (n + 8) − (n − 9) / (n + 7)
If you wish, you can simplify by finding the common denominator.
aₙ = [(n − 8) (n + 7) − (n − 9) (n + 8)] / [(n + 8) (n + 7)]
aₙ = [n² − n − 56 − (n² − n − 72)] / (n² + 15n + 56)
aₙ = 16 / (n² + 15n + 56)
The infinite sum is:
∑₁°° aₙ = lim(n→∞) sₙ
∑₁°° aₙ = lim(n→∞) (n − 8) / (n + 8)
∑₁°° aₙ = 1

The point C is 3/4 of the way from point A (-4,1) to point B (6,5). What are the coordinates of point C?

Step-by-step explanation:
The coordinates of point C are (7/2, 4).
What is midpoint of a line segment?The midpoint of a line segment is given as,
x = (a + c)/2
y = (b + d) / 2
Where (x, y) is the midpoint and (a, b) and (c, d) are the two endpoints.
We have,
C is a point between AB.
Point C is 3/4 of the way from point A (-4,1) to point B (6,5).
This means,
AC : CB = 3 : 1 = m : n
Now,
m = 3
n = 1
(-4, 1) = (a, b)
(6, 5) = (c, d)
C = (x, y)
x = (mc + na)/(m + n)
x = (3 x 6 - 4)/4
x = (18 - 4)/4 = 14/4 = 7/2
y = (md + nb)/(m + n)
y = (15 + 1)/4 = 16/4 = 4
Now,
The coordinates of C is (7/2, 4).
Thus,
C is at the point (7/2, 4).

A lab technician must screen 175 slides under the microscope each week. If she works 7 hours a day, 5 days a week, how many slides,on average, must she screen in one hour
Answer:
The lab technician must screen 5 slides per hour
Step-by-step explanation:
If the lab technician works 5 days a week, and 7 hours per day, then she works 5*7 = 35 hours a week.
Given she must screen 175 slides each week, we can calculate on average, the number of slides per hour needed to complete the work.
The average is calculated as:
[tex]\displaystyle average=\frac{\text{total slides}}{\text{total hours}}[/tex]
[tex]\displaystyle average=\frac{175}{35}=5\ slides/hour[/tex]
The lab technician must screen 5 slides per hour
