Answer: 2: an equation in the form y = mx + b
1. An x/y table may have two entries with the same x; not a function in that case.
2. That's a line with a slope; for each x there's a single y, definitely a function
3. Ordered pairs -- like the table, the same x with different ys is possible, which wouldn't be a function.
4. List of numbers -- a list isn't a function, at least not without more context
Which of the following is the equation of a line in slope intercept from a line with the slope of 2/3 and Y intercept at 0,-2
Answer:
y= 2/3x - 2
Step-by-step explanation:
b is were the line crosses the y intercept so its -2
and the slope is 2/3x

Alex is drawing rectangles with different areas on a centimetre grid he can draw 3 different rectangles with an area of 12cmsquared a) How many different rectangles could alex draw with an area of 11cmsquared? B)Give a reason for ur anwser
Answer:
Alex can only draw a rectangle with an area of 11 cm²
The reason for the answer is that 11 is a prime number
Step-by-step explanation:
We are told that Alex is drawing rectangles with different areas on a centimeter grid, and he can draw 3 different rectangles with an area of 12 cm²
We have the minimum grid length of centimeters = 1 cm, since we assume that only integers can be used.
That is to say:
12 = 1 x 12
12 = 2 x 6
12 = 3 x 4
These are the 3 different rectangles with an area of 12 cm²
Now we have to find how many rectangles Alex could draw with an area of 11 cm²
11 = 1 x 11
Therefore, only one factorization is possible. Which means that you can only draw a rectangle with an area of 11 cm²
The reason for the answer is that 11 is a prime number, which means only the common factor of 1 and the number itself, that is, 11.

50%
X + 100
Answer:
x = 350 gallons (amt of 60% solution that must be added)
Step-by-step explanation:
Amt of 60% solution = x gallons ; Amt of active ingredient = 0.6x gallons
Amt of 15% solution = 100 gallons ; Amt of active ingredient = 15 gallons
Amt of 50% solution = 100+x gallons ; Amt of active = 50 + 0.5x gallons
EQUATION:
Active ingredient: 0.60x + 15 = 50 + 0.50x
0.10x = 35
x = 350 gallons (amt of 60% solution that must be added)
Find the circumference of the circle below. (Use 3.14 for Pi)
A. 78.5 cm
B. 15.7 cm
C. 31.4 cm
D. 314 cm
so the right answer is 31.4 cm(option C)
please see the attached picture for full solution
Hope it helps
Good luck on your website
Answer:
C. 31.4 cm
Step-by-step explanation:
→The formula for finding the circumference of a circle is:
C = 2πr
→However, it states that we use 3.14 for π:
C = 2(3.14)r
→The "r," is the radius, which is a straight line from the perimeter to the center. In this case, it is already given to us as 5 cm.
C = 2(3.14)(5)
C = 31.4

Determine and prove which lines are parallel.: Need by Tuesday!! Thanks!
If the gradients are not the same, then there will be a point, which intersects. That contradicts the statement that theclines have no points in common.
Step-by-step explanation:
Parallel lines are lines that have the same gradient.
Because parallel lines have a fixed distance between each other,it means they will never meet, no matter how long they are extended.
Since parallel lines have the same slope by definition, they will never intersect. Parallel lines continue, literally, forever without touching.
Prove:
Suppose that there are two lines, line l and line m, which have no points in common. Both lines are in the same plane.
If the gradients are not exactly the same, then there will be a point, which intersects. That contradicts the first statement (which says l and m have no points in common), therefore the gradients must be the same in order for l and m to have no points in common.

The product of two positive numbers is 1,800. One number is twice the other number. The equation to determine the two numbers, with x representing the value of the lesser number, is x(2x) = 1,800. What is the value of the lesser number?
Answer:
600
Step-by-step explanation:
x+2x=1800
3x=1800
x=600
Answer:
- 30
Step-by-step explanation:
The 2 numbers are x and 2x and thir product is 1800, that is
x × 2x = 1800
2x² = 1800 ( divide both sides by 2 )
x² = 900 ( take the square root of both sides )
x = ± [tex]\sqrt{900}[/tex] = ± 30
The 2 numbers are 30 and - 30 with - 30 being the lesser number

y =
Answer:
y = -16.9
Step-by-step explanation:
→Add 0.8y to both sides:
-0.8y + 5.49 = -19.86 - 2.3y
5.49 = -19.86 - 1.5y
→Add 19.86 to both sides:
25.35 = -1.5y
→Divide both sides by -1.5:
-16.9 = y
Answer:
[tex] \boxed{y = - 16.9} [/tex]
Step-by-step explanation:
[tex] = > - 0.8y + 5.49 = - 19.86 - 2.3y \\ \\ = > - 0.8y + 2.3y + 5.49 = - 19.86 \\ \\ = > 1.5y + 5.49 = - 19.86 \\ \\ = > 1.5y = - 19.86 - 5.49 \\ \\ = > 1.5y = - 25.35 \\ \\ = > y = - \frac{25.35}{1.5} \\ \\ = > y = - 16.9[/tex]

The slope of the line is y-4= 1/2 (x-1)
Answer:
1/2
Step-by-step explanation:
in point slope form (y-h) = slope(x-k)
The equation in the slope-intercept form will be y = x/2 + 7/2. Then the slope of the equation is 1/2.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
y - 4 = 1/2 (x - 1)
Convert the equation into a slope-intercept form. Then we have
y - 4 = 1/2 (x - 1)
y - 4 = x/2 - 1/2
y = x/2 - 1/2 + 4
y = x/2 + 7/2
The equation in the slope-intercept form will be y = x/2 + 7/2. Then the slope of the equation is 1/2.

Answer:
k = 18
Step-by-step explanation:
6(3k + 15) − 16k = 7k
Distribute
18k +90 - 16k = 7k
Combine like terms
2k + 90 = 7k
Subtract 2k from each side
2k+90-2k = 7k -2k
90 = 5k
Divide by 5
90/5 = 5k/5
18 = k
Answer:
[tex]k = 18[/tex]
Step-by-step explanation:
[tex]6(3k + 15)- 16k = 7k \\ 18k + 90 - 16k = 7k \\ 18k - 16k - 7k = - 90 \\ - 5k = - 90 \\ \frac{ - 5k}{ - 5} = \frac{ - 90}{ - 5} \\ k = 18[/tex]
