Answer:
The answer would be C, hope i helped
Step-by-step explanation:
First you have to get x by itself. So you do 90-90= 0 and 30-90= -60 which gets:
90 - 3/2x < 30 to -3/2x < -60
Then, you do -3/2 - (-3/2)= 0 and do the same to -60. -60 - (-3/2) = -58.5
which makes it look like
X = -58.5
-58.5 is a smaller number than -40 which means, when you fill it in for x it works
-58.5 ≤ -40

Points are plotted on the ordered pairs 1, 1, and 2, 2, and 3, 3. b A graph is shown with title Movie Rentals. The horizontal axis label is Days, and the vertical axis label is Cost of rental in dollars. Points are plotted on the ordered pairs 1, 3 and 2, 5, and 3, 7. c A graph is shown with title Movie Rentals.

The horizontal axis label is Days, and the vertical axis label is Cost of Rental in dollars. Points are plotted on the ordered pairs 2, 1 and 4, 2, and 6, 3.
Answer:
This is clearly a linear relationship. If Alex rented the movie for 0 days, he'd owe nothing. If he paid $6 for a 3-day rental, the slope of this line would be m = rise / run = $6/(3 days) = $2/day, which is positive.

Which equation represents the polar form of x - y = 0?
Answer:0=0
Step-by-step explanation:
Answer: B
Step-by-step explanation:
Write an equation of the line through the point (-10, 0) with slope of -1/2
Answer:
y = 1/2x + 5
Step-by-step explanation:
We can use point slope form since we are given a point and the slope
y -y1 = m( x-x1)
where ( x1,y1) is a point and m is the slope
y -0 = 1/2 (x- -10)
y = 1/2( x+10)
y = 1/2x + 5

Cos30*cos50+sin30*sin50
9514 1404 393
Answer:
cos(20°)
Step-by-step explanation:
The angle difference formula for cosine is ...
cos(α -β) = cos(α)cos(β) +sin(α)sin(β)
If we let α = 50° and β = 30° then this matches the given expression:
cos(50° -30°) = cos(50°)cos(30°) +sin(50°)sin(30°) = cos(20°)
15 points and BRAINLIEST Alyssa invested $500 into an account. The value of the account after t years can be found using the function r(t) = 500(1.068). What is the percent annual rate of change
in the value of the account?
Answer:
annual rate: r = 0.068
Step-by-step explanation:
The formula is r(t) = P(1+r)^t
Since the time is already in years we just have to solve for the rate
1 + r = 1.068
r = 0.068
The rate of change in the value of account is 0.068
What is rate of change?
'Rate of change is used to mathematically describe the percentage change in value over a defined period of time.'
According to the given problem,
Annual rate:
r = 0.068
The formula is r(t) = [tex]P( 1 + r )^{t}[/tex]
Therefore, solving for the rate
⇒ 1 + r = 1.068
⇒ r = 0.068

A bag contains 70 pencils out of which 15 are green and 30 are blue. How many pencils of other colour are in the bag. A pencil is selected from a bag at random .What is the probability that it is blue?
Answer:
a) There are 25 pencils of other colour in the bag.
b) P(Blue) = 3/7
Step-by-step explanation:
A bag contains 70 pencils out of which 15 are green and 30 are blue.
a) How many pencils of other colour are in the bag?
This is calculated as:
70 - (15 + 30)
= 70 - 45
= 25 pencils
Hence, there are 25 pencils of other colour in the bag.
b) A pencil is selected from a bag at random .What is the probability that it is blue?
P(Blue) = Number of Blue pencils/Total number of Pencils
P(Blue) = 30/70
P(Blue) = 3/7

Options A, B and C are the correct answers.
Given that, the bar chart shows the relative frequencies of students from grades 6 to 12 who participate in the community service activity.
How do you find relative frequency?Relative frequency can be defined as the number of times an event occurs divided by the total number of events occurring in a given scenario.
Relative Frequency = Subgroup frequency/ Total frequency.
Relative Frequency = f/ n.
From the given bar chart we can see that
The maximum number of participating students was in grade 9.The number of participating students in grade 6 was equal to the number of participating students in grade 7.The relative frequency of all participating students in grades 6 and 7 combined was 0.60.Therefore, options A, B and C are the correct answers.
