Answer:
[tex]y=4x-7[/tex]
The graph in the attached figure
Step-by-step explanation:
In this problem I will assume the the function is linear
we have the point (2,1)
we know that
y increases by 4 when x increases by 1
Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
so
The slope of the linear function is
[tex]m=\frac{4}{1}[/tex]
Find the equation of the line in point slope form
[tex]y-y1=m(x-x1)[/tex]
substitute
[tex]y-1=4(x-2)[/tex]
Convert to slope intercept form
Isolate the variable y
[tex]y-1=4x-8\\y=4x-8+1\\y=4x-7[/tex]
see the attached figure to better understand the problem
The question pertains to the characteristics of a linear function whose graph passes through the point (2, 1) with a slope of +4, indicating an increase of 4 in y for every increase of 1 in x. The line's positive slope suggests the graph rises as the x-value increases. The equation of the line is y=4x-7.
Explanation:The student is asking a question about the characteristics of a linear function based on its graph. Specifically, since the graph passes through the point (2, 1) and the value of y increases by 4 when x increases by 1, we can conclude that the slope of the line is +4. This is because the slope of a line represents the change in y divided by the change in x. Given that the slope is positive, this line will show an upward trend on the graph as the x-value increases, much like other graphs with a positive slope.
To find the equation of the line, we start by using the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. We use the point (2, 1) and the slope 4 to solve for b. The process is as follows:
1 = 4(2) + b
1 = 8 + b
b = -7
Therefore, the equation of the function is y = 4x - 7.
Which equation demonstrates the multiplicative identity property?
O (-3+5)+1=-3+57
O (-3+5)(1)=-3+5;
O (-3+5)(-3+5)=-16-30;
(-3+5)(3-5) = 16+30;
Answer:
(-3+5)(1)=-3+5
Step-by-step explanation:
The multiplicative identity is 1.
The multiplicative identity property days that, if you multiply a real number by 1, that result is the same real number.
This is demonstrated in option B of the given alternatives, where we have:
[tex]( - 3 + 5)(1) = - 3 + 5[/tex]
The multiplication by did not change b the value.
7x - 7 = 126 what is x
Answer:
19
Step-by-step explanation:
7x-7=126
add+7 to 126 and you will get 133
7x/133
x=19
Answer:
x = 19
Step-by-step explanation:
7x - 7 = 126
Add 7 to each side
7x - 7+7 = 126+7
7x = 133
Divide each side by 7 to isolate x
7x/7 = 133/7
x = 19

Solution:
Given that,
Translate the sentence into an inequality
The sum of a number times 9 and 30 is at least - 15
Let "c" be the unknown variable
"at least" means "greater than or equal to"
From given,
sum of a number times 9 and 30 = 9x + 30
Which means,
[tex]9x +30\geq 30[/tex]
Thus the given sentence is translated into inequality
The sentence 'The sum of a number times 9 and 30 is at least - 15' can be translated into the inequality
[tex]9c + 30 \geq -15[/tex]Explanation:The sentence 'The sum of a number times 9 and 30 is at least - 15' can be translated into an inequality by first recognizing the mathematical operations being described. The phrase 'a number times 9' is multiplication, so let's represent this number with the variable c. Thus, this part is 9c. The word 'sum' represents addition. Finally, 'is at least' indicates that the sum is greater than or equal to a particular value (-15 in this case).
Putting these elements together, we get the inequality
[tex]9c+30\geq -15[/tex]This is the inequality that represents the sentence.

Anyone knows how to do this
Answer:
length = x - 2
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = length × width
Here A = x² - 7x + 10 and width = x - 5
x² - 7x + 10 = length × (x - 5) ← divide both sides by (x - 5)
length = [tex]\frac{x^2-7x+10}{x-5}[/tex] ← factor the numerator
= [tex]\frac{(x-5)(x-2)}{x-5}[/tex] ← cancel common factor (x - 5) on numerator/ denominator
= x - 2
Thus length = x - 2 metres

To make the sum or difference of 3/4+1/3
Answer:
13/12 or 1 1/12
Step-by-step explanation:
First, I like to line up the fractions like this:
3/4
1/3
You can't add them yet because they have different denominators, so we have to get them to the same denominator first. What is a number 3 and 4 can be multiplied by? Let's use 12. So, we want both of their denominators to be 12. How do we do that? 4 times what equals 12? 3. However, whatever you multiply the denominator by, you have to do to the numerator as well. Here is what we have:
3/4 x 3
1/3
3x3 equals 9, so your first fraction is 9/12. Then, do the second fraction. 3 times what equals 12? 4. So, multiply the numerator, 1, by 4 to get 4. So, your second fraction is 4/12. Now, you have to add them together, 9+4 = 13. The denominator stays the same. So, your sum is 13/12. If you want to, you can also simplify it to a mixed number into 1 1/12.

edge length?
nel
[tex]\huge\boxed{\sqrt[3]{\text{V}}}[/tex]
The volume of a cube is found by cubing the edge length — or multiplying it by itself twice.
In other words, the volume of a cube is as follows:

Step-by-step explanation:
a square green rug has a yellow square in the center. The side of the yellow square is x inches the width of the green band that surrounds the yellow square is 7 inches. What is the area of the green band?
Answer:
28x +196 in^2
Step-by-step explanation:
The outside dimension of the square green rug is (x+14), so its area is (x+14)^2. The area of the green band will be the difference between this and the area of the yellow square, (x^2).
green band area = (x +14)^2 -(x^2) = x^2 +28x +196 -x^2
green band area = 28x +196 . . . . square inches
A plastic storage bin is shaped like a rectangle or prism. The height of the band is 9 inches. The bottom of the band has an area of 180 in.². What is the volume of the storage bin
Answer:
v = 1620 ^3
Step-by-step explanation:
If the area of the bottom is 180 sq in and the height is 9 in then this is how you would solve the problem.
To get area of the volume is l * w * h
Because of the associative property we can do this in any order we want
If we know that l * w is 180, then all we have to do is multiply 180 by 9
180 * 9 = 1620
