The line y=kx+4 goes through the point (2,-2)
K=-3
Sketch the graph of the line (need ASAP!)
Answers
The graph of the linear equation:
y = -3x + 4
Can be seen in the image at the end.
How to sketch a graph of the line?
Here we know that the equation for the line is:
y = k*x + 4
We know that this line goes through the point (2, -2), then we can replace these values in the above line so we get the value of k.
-2 = k*2 + 4
With this, we can find the value of k.
-2 - 4 = k*2
-6 = k*2
-6/2 = k = -3
Then the line is:
y = -3*x + 4
If we evaluate in x = 0, we get:
y = -3*0 + 4 = 4
So, at this point we know that the line passes through points (0, 4) and (2, -2), so to graph the line, we just need to graph these two points and draw a line that connects them, like in the example below.

What is defined as the term highest common factor?The greatest common factor is the largest number that is a factor of two numbers or more (GCF). The largest number (factor) divides them, yielding a Natural number. Once all of the number's factors have been identified, there are a few that are shared by both.The length of the metallic paper is 24 inches.
The length of the pink glittery paper is 36 inches.
To find the largest size, find the HCF of both number.
First find the factors using prime factorisation;
24 = 2×2×2×3
36 = 2×2×3×3
Find the common term,
HCF (24, 36) = 2×2×3
HCF (24, 36) = 12

Round to the place value of the underlined digit 698,072 the underlined digit is 6
Answers
We get 700,000 after rounding off to the place value of the underlined digit in the number 698,072.
According to the question,
We have the following number with 6 as the underlined digit:
698,072
When rounding off the number, please note that the digits to the right of the underlined digit would be zero. However, we need to be careful where we need to scale up the underlined number or it would remain the same.
For this, we need to check the number to the right of the underlined digit. If the number right next to the underlined digit is greater than 5 then the underlined digit has to be scaled up. And if it is less than 5 then the underlined digit remains the same.
So, after rounding off we will get:
700,000
Hence, the number after rounding off to 6 in 698,072 is 700,000.

D.

Answers
========================================================
Explanation:
Imagine a rectangle that is 12 by 26. Multiplying the length and width will get us the area.
We can break the 12 into 10+2
Also, break the 26 into 20+6
Check out the diagram below. We have 4 smaller rectangles. Finding the product of those sub-areas will then get us the partial products needed.
In the bottom right corner we have a 2 by 6 rectangle, so it has area 2*6 = 12 square units. This is one of the four partial products. The other partial products are found the same way.
Once you determine the four partial products, we then add them up
12+60+40+200 = 12+100+200 = 12+300 = 312
Therefore, 12*26 = 312 which we can use a calculator to confirm.

What is Percentage?
A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, while the percent symbol, "%," is most frequently employed. A % has no dimensions and no associated unit of measurement.
Given,
No. of students using Tablet = 164
No. of students using book = 18%
The students in sixth grade either use book or tablet
When 164 student use tablet then remaining use tablet, that is 18%
Then, the remaining percent would be the students using tablet:
100% - 18% = 82%
converting 82% into decimal we get,
82 /100
i.e, 0.82
Number of students in sixth grade = 164/0.82
= 200 students
Hence, 200 students are in sixth grade

Answers
The percentage of increase in her score is 6.82%
What is the percentage of increase?Here we will define her first score, 88, as the 100%.
So we can write the relation:
88 = 100%.
Her next score is 94, this will be a percentage X, then we can write:
94 = X
Taking the quotient between the two equations:
94/88 = X/100%
Solving this for X we get:
(94/88)*100% = X = 106.82%
The difference between the percentages gives the increase:

Answers
We need to find which expression represents the situation given, in this case we have two values a distance (80 ft) and the elapsed time (40 s). The time is the input of the equation, it will be placed on the "x" variable and the distance is the output of the equation, it will be placed on the "y" variable. We need to find the expression that outputs "80" when we input 40. Let's check them one by one:
A.
[tex]y=\frac{1}{2}\cdot40=20[/tex]This outputs 20 ft when we input 40 s, therefore it is not this one.
B.
[tex]y=4\cdot40=160[/tex]This one outputs 160 ft when we input 40 s, therefore it is not this one.
C.
[tex]y=2x=2\cdot40=80\text{ }[/tex]This one outputs 80 ft when we input 40 s, therefore this is the correct expression.
We now need to use this expression to calculate the distance the person will travel in 10 seconds, so we will make x equal to 10 s.
[tex]y=2\cdot10=20\text{ }[/tex]The person will walk 20 ft.
The correct option is "C".

The highest common factor of the given number is 35.
What is the highest common factor?The biggest positive number that divides each integer in a set of two or more is known as the greatest common divisor in mathematics. The GCD of two integers x, and y is the greatest common divisor of x and y. A group of numbers' largest factor that they all share is known as the group's greatest common factor (GCF). Components 2 and 4 are shared by the numbers 12, 20, and 24, for instance. We claim the GCF of 12, 20, and 24 equals 4 since 4 is the largest. The greatest integer that may divide two or more numbers is known as the highest common factor (HCF), sometimes known as the GCF. The definition of highest is the highest or largest number. Any two or more numbers that share a common meaning.

a ≠ b is the information that a and b are not equal.
