Answer:
If y> or y>=, (>= means greater than or equal to), then you shade up. If y< or y<=, (<= means less than or equal to), then you shade down. I remember this by up: greater (because when something is bigger, it's higher) and down: less (because if it's smaller, it's lower). I hope that helps.
a migrating bird flies 468 miles in 13 hours. how many miles does it fly in 3 hours?
Answer:
The answer is 108mi
Step-by-step explanation:
to solve this problem, we need to write a ratio.
[tex]\frac{468mi}{13hrs}[/tex]
to solve for 3 hours, we need to figure out how many miles the bird can fly in 1 hour. to do that, we need to divide the numerator and denominator by 13.
[tex]\frac{36mi}{1hr}[/tex]
now we have a unit rate that represents distance covered per hour.
to solve for 3, we need to multiply the numerator and denominator by 3.
[tex]\frac{108mi}{3hrs}[/tex]
the question is asking for miles. therefore, the bird can fly 108mi in 3 hrs.
hope this helps!
Answer:
108 miles
Step-by-step explanation:
For this problem you can create a proportion:
[tex]\frac{468 miles}{13 hours}[/tex]
To find how many miles it flies in 3 hours, we need to find the unit fraction. Do this by making the denominator (bottom number) 1:
here, we must divide by 13:
[tex]\frac{468 miles}{13 hours}[/tex]÷[tex]\frac{13}{13}[/tex]= [tex]\frac{36 miles}{1 hour}[/tex]
Each hour, they fly 36 miles.
To find how many miles they fly in 3 hours, make a proportion:
[tex]\frac{36 miles}{1 hour}[/tex]=[tex]\frac{x miles}{3 hours}[/tex]
Then, solve:
use cross multiplication:
36·3=108
x·1=x
108=x

y = 2x = 5
y = X - 2
Answer:
Both of these equations are in slope-intercept form. The slope-intercept form of a linear equation is: y=mx+b
Where m is the y-intercept value.
y=-2x+5
y=-2x+20
The slope of the two equations are: m1=−2 and m2=−2
Step-by-step explanation:
Because the have the same slope it means the lines represented by these two equations are either parallel or are the same line.
The y-intercepts for the two lines are:b1 = 5 and b1=20

Find the slope of (1,8) and (3,12) ?
Answer:
The slope is 2.
Step-by-step explanation:
Slope formula is rise/run. So in other words, it is y2-y1/x2-x1. In this case it would be 12-8/3-1. That equals 4/2. You need to simplify that by dividing both 4 and 2 by 2. So, that gives you 2/1. Whenever you have a number over 1 that is the same as saying just the numerator. So the slope would be 2.

You had 23 dollars to spend on 4 avocados. They were very green. After buying them you had 11 dollars. How much did each avocado cost?
Answer:
the avacodos cost 12
Step-by-step explanation: if you sutract 23 by 11 you get 12 and if you chek you ansewer by adding 12+11=23
The answer is $3.
Step-by-step explanation:
1. Let's subtract 11 ($ remaining) from 23 ($ we had originally) to see how much we spent in total. (23 - 11 = 12)
2. Divide 12 ($ spent) and 4 (Avocados bought) to find out how much each avocado cost. (12 ÷ 4 = 3)

There are 24 calories in a candy bar. How many calories are there in 33 candy bars ?
Answer: 406
Step-by-step explanation:
Answer:
792
Step-by-step explanation:
The answer is 792 because, we know that there is 24 calories in each bar, so, when calculating total amount of, you wan to multiply that amount by however many bars there are. The reason you multiply is because(using this example) when you have a bar with 24 calories and another bar with the same amount, you just add the two calorie amounts together, or 24 + 24. Since you have 33 bars, you would do that 33 times, which is the same as 24 x 33. So if you calculate 24 x 33, you get 792. Another way to solve this is you can use the formula x=cb where x is the total amount of calories, c is the number of calories in one bar, and b is how many bars you have.
Which is a correct first step in solving the inequality –4(2x – 1) > 5 – 3x?

A recipe requires 3 cups of sugar for every 1 ½ cup of flour. At this rate, how much flour would be needed for 2 cups of sugar?
Answer:
1/2
Step-by-step explanation:
On her first day in a hospital, Kiri receives u1 milligrams (mg) of a therapeutic drug. The amount of the drug Kiri receives increases by the same amount, d, each day. On the seventh day, she receives 21 mg of the drug, and on the eleventh day she receives 29 mg.
a. write down an equation, in the terms u1 and d, for the amount of the drug that she receives on the seventh day.
b. write down an equation, in terms of u1 and d, for the drug that she receives on the eleventh day.
c. write down the value of d and the value of u1.
Answer:
a. 21 = u1 + 6·d
b. 29 = u1 + 10·d
c. d = 2, u1 = 9
Step-by-step explanation:
a. The given parameters are;
The amount of therapeutic drug Kiri receives on her first at the hospital = u1 milligrams
The amount of drug increase received by Kiri each day = d
The amount of drug Kiri received on the seventh day = 21 mg
The amount of drug she received on the eleventh day = 29 mg
Therefore, we have an arithmetic progression with the formula for the nth term given as follows;
aₙ = a₁ + (n - 1)·d
Where;
a₁ = u1
n = The number of terms
Therefore, for the 7th day, the amount of drugs she receives, which is 21 milligrams, is given as follows;
a₇ = u1 + (7 - 1)·d = u1 + 6·d = 21
The equation for the amount of drugs she receives in terms of u1 and d on the seventh day is given as follows;
21 = u1 + 6·d
b. For the eleventh day, the amount of drugs she receives, which is 29 milligrams, is given as follows;
a₁₁ = u1 + (11 - 1)·d = u1 + 10·d = 29
Therefore, the equation for the amount of drugs she receives in terms of u1 and d on the eleventh day is given as follows;
29 = u1 + 10·d
c. Therefore, we have two equations which are given as follows;
21 = u1 + 6·d................(1)
29 = u1 + 10·d..............(2)
Subtracting equation (1) from equation (2) gives;
29 - 21 = (u1 + 10·d) - (u1 + 6·d)
8 = 4·d
d = 8/4 = 2
d = 2
From equation (1), we have;
21 = u1 + 6·d = u1 + 6×2 = u1 + 12
21 = u1 + 12
21 - 12 = u1
∴ u1 = 9
d = 2, u1 = 9.
identify the sequence 18,13,8,3,-2 PLZ HELPPPPP
The common difference between each term is -5. The nth term of the sequence as follows: aₙ = 18 - 5(n-1)
The given sequence is 18, 13, 8, 3, -2.
To identify the pattern in the sequence, we can observe that each term is decreasing by 5. Starting from 18, we subtract 5 to get the next term, and so on. The common difference between each term is -5.
Using this pattern, we can continue the sequence as follows:
-2 - 5 = -7
-7 - 5 = -12
-12 - 5 = -17
-17 - 5 = -22
The extended sequence would be -2, -7, -12, -17, -22.
In terms of the general formula, we can represent the nth term of the sequence as follows:
aₙ = 18 - 5(n-1)

Answer:
x+65≤84
Step-by-step explanation:
Inequality that represents the number 'x' of additional people who can enter the restaurant is -
x + 65 ≤ 84
What is inequality?
Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.
Given is a restaurant which has 65 people in it. The restaurant has a maximum capacity of 84 people.
Assume that 'x' more people can enter inside the restaurant. Then -
the inequality can be written as follows -
x + 65 ≤ 84
65 people were already inside. 'x' more people can enter it such that the total number of people inside is either less or greater than 84.
Therefore, inequality that represents the number 'x' of additional people who can enter the restaurant is -
