System of linear equations- A set of ____ linear equations in the same variables.
AND
Solution(s) of a system of linear equations- An ordered pair that is a ____ of the system. The point where the lines _____ or _____!
Answer:
Step-by-step explanation:
System of linear equations - A set of two or more linear equations in the same variables.
Ex:
y = 2x + 8
y = x + 2
These are both linear equations, with same variables (x and y)
Solution(s) of a system of linear equations- An ordered pair that is a solution of the system. The point where the lines intersect or meet.
I'm not very sure if these are the exact words your teacher or lesson used, but these words should be perfectly fine.

Step-by-step explanation:
In this table, for every 1 hour that passes, there will be 7 screams. So, if we want to fill out the table, all we have to do is divide or multiply by 7:
6 hours * 7 = 42 screams
56 / 7 = 8 hours
12 hours * 7 = 84 screams
We want to solve different problems with linear relations so we can get the code.
We will find the code: SCARY
a) First we want to see which artist is the fastest.
To see this, we just need to take the quotient between the number of faces painted and the time it takes to each one to paint these faces.
We can see that the faster one is artist S, with a rate of:
r = 8 faces /100min = 0.08 faces/min
Then here the correct option is S.
b) Here we must solve:
(0.08 faces/min)*T = 1 face
T = (1 face)/(0.08 faces/min) = 12.5 min
So the correct option is C.
c) in two and half hours there are 2.5*60min = 150 minutes.
So we must compute:
(0.08 faces/min)*150 min = 12 faces
The correct option here is A.
d) The rate of artist Z is:
r = (6 faces)/(78 min) = (0.077 faces/min)
Then we must solve:
(0.077 faces/min)*T = 10 faces
T = (10 faces)/(0.077 faces/min) = 130 min
So the correct option is R.
e) First, the rate at which artist A works is:
r = (9 faces)/(120 min) = 0.075 faces/min.
The time needed to paint 18 faces is given by:
(0.075 faces/min)*T = 18 faces
T = (18 faces)/(0.075 faces/min) = 240 min = 4 hours.
We know that the artist wins $11 per hour, then in 4 hours the artist wins $44, the correct option is Y.
Then the code is:
SCARY

PLS HELP!!! The snowy tree cricket is sometimes called the temperature cricket because the frequency of its chirps varies based on the temperature. The number of snowy tree cricket chirps per minute is 148 less than 4 times the outside temperature in degrees Fahrenheit. The equation x=4f-148 relates the number of chirps per minute x and the outside temperature in degrees Fahrenheit f. What is the change in chirps per minute for each increase in temperature by 1 degree Fahrenheit? Explain your answer.
Answer:
Step-by-step explanation:
62 degrees Fahrenheit
Step-by-step explanation:
The number of snowy tree cricket chirps per minute is 148 less than 4 times the outside temperature in degrees Fahrenheit.
Let x = number of chirps
f = temp in Fahrenheit
x = 4f -148
Now let x = 100
100 = 4f-148
Add 148 to each side
100+148 = 4f-148+148
248 = 4f
Divide each side by 4
248/4 = 4f/4
62=f
The changes in chirps per minute for each increase in temperature by 1 degree Fahrenheit will be 252.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, a snowy tree cricket makes 148 chirps per minute, which is less than four times the ambient temperature in Fahrenheit.
x=4f-148
Suppose x,f be the number of chirps and temperature in Fahrenheit
x = 4× 1 -148
Suppose the number of chirps is 100.
x = 4(100)-148
x =400 - 148
x = 252
100+148 = 4f-148+148
248 = 4f
f =248 / 4
f = 62
Thus, the changes in chirps per minute for each increase in temperature by 1 degree Fahrenheit will be 252.

Answer:
22 millimeters
Step-by-step explanation:
Firstly, to find the median of a box and whisker plot, you find the center line of the plot and look to which number on the line it is pointing to. Median = middle, to help you remember.For the diameter of bicycle tires, the median appears to be 585 millimeters, as it is exactly halfway between 580 and 590.For the diameter of automobile tires, the center line is on 840 millimeters.The question is asking for the difference of the medians between the bike tires and the automobile tires. You would subtract 840 from 585 to find this. This will get us 255.Now we find the ranges of both graphs. The range is subtracting the largest graphed number from the smallest. For bike tires, the range is 621 - 559, which is 62. I am unclear if the person who created the graph intended for the end lines to be one number off. If not, then it would be 60.The range for automobile tires would be 881 - 821, which equals 60.The question asks for "how many times the difference between the medians of both automobile and bike tires is the range of the bike tires." This is asking us to subtract the combined medians of the graphs to the range of bike tires.First, we need to add both medians together. This would be 585 + 840, which equals 1,425. Next, we subtract the range of bike tires, 62, from 1,425. This equals 1,363.The question asks how many times the difference is. To find how many times 62 goes into 1,363, we need to divide. 1,363 ÷ 62 = 21.98, which rounds up to 22.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.

(y + 1){2} = 9,
1 + 72/y = 10,
Answer:
1. y = 7
2. y = 6
3. y = 7/2
4. y = 8
Step-by-step explanation:
I searched it up and found the answer.
Let's solve each equation one by one :
7y + 7 = 56➝ 7y + 7 = 56
➝ 7y = 56 - 7
➝ 7y = 49
➝ y = 49 / 7
➝ y = 7
42 - 6y = 6➝ 42 - 6y = 6
➝ - 6y = 6 - 42
➝ - 6y = - 36
➝ y = -36 / - 6
➝ y = 6
( y + 1 )² = 9➝ ( y + 1 )² = 9
➝ y + 1 = √ 9
➝ y + 1 = 3
➝ y = 3 - 1
➝ y = 2
1 + 72 / y = 10➝ 1 + 72 / y = 10
➝ 72 / y = 10 - 1
➝ 72 / y = 9
➝ 72 = 9y
➝ 9y = 72
➝ y = 72 / 9
➝ y = 8

Answer:
D
Step-by-step explanation:
Area of figure
= area of triangle +area of rectangle
Area of triangle
= ½ ×base ×height
= ½(6)(3.5)
= 10.5 ft²
Area of rectangle
= length ×breadth
= 6(4.6)
= 27.6 ft²
Area of figure
= 10.5 +27.6
= 38.1 ft²
Thus, option D is correct.
38.1 square feet
===============================================
Work Shown:
area of triangle = base*height/2 = 6*3.5/2 = 10.5
area of rectangle = base*height = 6*4.6 = 27.6
total area = triangle + rectangle = 10.5+27.6 = 38.1 square feet
