Find an ordered pair (x, y) that is a solution to the equation.
5x + y=9
Answer:
Some points are: (1, 4), (0, 9), and (3, -6), just to name a few.
Step-by-step explanation:
We can find out an ordered pair for this equation by plotting the line 5x + y = 9 on a graph. If you graph 5x + y = 9, then we see that the point (1, 4) is a point that the line intersects. Let's substitute that values:
5(1) + 4 = 9
Order of operations, multiply first...
5(1) = 5
Then it becomes...
5 + 4 = 9
We can see that 5 plus 4 actually does equal 9, so the point (1, 4) works. Let's try a different point. We can see the point (0, 9) is another point that the line intersects. Same process for this point too.
5(0) + 9 = 9
Then...
5(0) = 0
0 + 9 = 9
We see that 0 plus 9 ALSO works, but let's try one more time. Another point that works is the point (3, -6) Again, same process.
5(3) + -6 = 9
That is equal to:
5(3) - 6 = 9
Simplify...
5(3) = 15
15 - 6 = 9
15 minus 6 works as well! Any point that the line intersects will be a solution for the equation. I hope this helps!

What is the equation of the line that passes through (4, -1) and (-2, 3)?
Answer:
y= - 4/6x+1.66
Step-by-step explanation:
To get the slope you subtract y2-y1 / x2-x1. This gives the slope. Then you need to get the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
f(x) = 3x2 – 12x +1
find the vertex.
Answer:
(2,-11) is the vertex
Answer:
(2, -11)Step-by-step explanation:
[tex]f(x)=3x^2-12x+1\\\\f(x)=3(x^2-4x)+1\\\\f(x)=3(x^2-2\cdot x\cdot2+2^2-2^2)+1\\\\f(x)=3(\underline{x^2-4x+4}-4)+1\\\\f(x)=3[(x-2)^2-4]+1\\\\f(x)=3(x-2)^2-12+1\\\\f(x)=3(x-2)^2-11[/tex]
the vertex form of parabola's equation is: f(x) = a(x - h)² + k with vertex (h,k)
x-h = x-2 ⇒ h = 2
+k = -11 ⇒ k = 11
Explain the difference between (-5)2 and -52. Your answer:
Answer:
-5(2) is different from -52 because -5(2) equals -10.
Step-by-step explanation:
-5(x) implies that -5 is being multiplied by x. Any time 2 numbers (one in parenthesis) are next to each other without a symbol inbetween it implies multiplication

Two-thirds of the dairy cattle on a farm are in the barn. One-fourth of the beef cattle are in the barn. There are 24 dairy cattle and 16 beef cattle in the barn. How many more beef cattle are on the farm than dairy cattle?
There are ? more beef cattle on the farm than dairy cattle.
Answer:
28 more beef cattle.
Step-by-step explanation:
Do 16*4 since 1/4 = 16 beef cattle. 16*4=64 total beef cattle on the farm.
Then do if there are 24 dairy cattle in the barn and that is 2/3 of all the cows.
1/3 = 12 so the total number of dairy cows on the farm is 12*3=36
Now subtract 64-36=28
There are 28 more beef cattle than dairy cows.
Hope this Helps!!
The number of cattle more than the number of beef will be 12.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Two-thirds of the dairy cattle on a farm are in the barn. One-fourth of the beef cattle are in the barn. There are 24 dairy cattle and 16 beef cattle in the barn.
Then the number of cattle is calculated as,
⇒ (2/3) x 24
⇒ 16
Then the number of beef is calculated as,
⇒ (1/4) x 16
⇒ 4
Then the number of cattle more than beef is calculated as,
⇒ 16 - 4
⇒ 12
The number of cattle more than the number of beef will be 12.

The volume of a right cylinder is 155.4 ft.3. The radius is
3 ft. Determine the height of the cylinder.
h=16.5ft.
h=17.3ft.
h=127.2ft.
h=5.5ft.
Answer:
5.499 = h likely if you used a better value for pi, it would be 5.5 = h
Step-by-step explanation:
Givens
V = 155.4
r = 3
pi = 3.14
Formula
V = pi*r^2*h Solve for h
Solution
155.4 = 3.14 * 3^2 * h 3^2 = 9
155.4 = 3.14 * 9 * h Combine the right
155.4 = 28.26 * h Divide by 28.26
155.4/28.26 = 28.26*h/28.26
5.499 = h
By first identifying the critical points of this function by determining the first derivative, and then calculating the second derivative at the crucial points, you may determine the volume's maximum. The critical point is a maximum if the second derivative is negative.
What determine height H of the cylinder, the height h cone?When a cone and cylinder have comparable heights, the cylinder's volume is three times greater than a cone's volume. Determine the cone's volume. To the tenth of a cubic centimetre nearest, round.
Therefore, a cylinder with the same base radius and height has a volume that is equal to one-third that of a cone.Learn more about cylinder.

Vertical angles equal 360 in total and the angles across from each other equal the same. 100 x 2 = 200
360-200 = 160

The slope equals the rise divided by the run: Slope =riserun Slope = rise run . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it.
