Which equation represents a line that passes through (4, 1/3) and has a slope of 3/4?
Answers
Step-by-step explanation:
let the equation be y - y1 = 3/4(x - x1)
sub (4, 1/3):
y - 1/3 = 3/4(x - 4)
therefore answer is option 2.

Answer:
[tex]y-\frac{1}{3} =\frac{3}{4} (x-4)[/tex]
Step-by-step explanation:
To see which equations have the slope of 3/4, we just need to focus on the right half of the equations to see what the multiplier of x is.
Equations 1 and 3 can be eliminated because they have a slope of [tex]\frac{1}{3}[/tex] and 4 respectively.
Now we can decide between 2 and 4 by plugging in the point [tex](4,\frac{1}{3})[/tex] to see which works properly.
Simplify equation 2
[tex]y-\frac{1}{3} =\frac{3}{4} (x-4)\\\\y-\frac{1}{3} =\frac{3}{4}x-3\\\\y=\frac{3}{4}x-\frac{8}{3}[/tex]
Plug in the point
[tex]\frac{1}{3} =\frac{3}{4}(4)-\frac{8}{3} \\ \\\frac{1}{3} =3-\frac{8}{3} \\\\\frac{1}{3} =\frac{9}{3} -\frac{8}{3} \\\\\frac{1}{3} = \frac{1}{3}[/tex]
This checks out, so equation 2 is your answer.

-3/5
Step-by-step explanation:
always remember rise by run. subtract the second y value from the first (9 minus 6) and the same with the x values (1-6). rise is y axis and run is x axis. therefore, you get 3/-5 or -3/5. (because 9-6 is 3 for the numerator and 1-6 is -5 for the denominator)
Whats the slope of the equation 6x + 8y = 16?
Answers
Answer:
-3/4
Step-by-step explanation:
6x+8y=16
(subtract 6x from both sides)
8y=-6x+16
(divide everything by 8)
y=-6/8x+16
(simplify)
y= -3/4x+16
this is now in y=mx+b form. m=slope

1. Draw the points on the graph to represent the solutions.
2. What are the solutions? List them as ordered pairs.
(x,y)
10
3. Based on the graph, would you expect the discriminant
to be positive, negative, or equal to zero?
Answers
Answer:
1. The solutions marked on the attached graph
2.The solutions are (-2, 0) and (6, 0)
3. The discriminant would be positive
Step-by-step explanation:
The solution of the quadratic equation is the values of x at y = 0, which means the points of intersection of the graph and the x-axisThe discriminant is positive if the graph intersects the x-axis at two different pointsThe discriminant is zero if the graph intersects the x-axis at only one pointThe discriminant is negative if the graph does not intersect the x-axisBased on the given graph
1.
Look at the attached figure to see the solutions
2.
∵ The graph intersects the x-axis at points (-2, 0), (6, 0)
∴ The solutions are (-2, 0) and (6, 0)
3.
∵ The discriminant is positive if the graph intersects the x-axis
at 2 different points
∵ The given graph intersects the x-axis at points (-2, 0) and (6, 0)
→ They are different points
∴ The discriminant would be positive

Step 1: Define systems
3x + 3y = 27
x - 3y = -11
Step 2: Solve for x
Eliminate y (add equations): 4x = 16Divide 4 on both sides: x = 4Step 3: Solve for y
Define original equation: x - 3y = -11Substitute in x: 4 - 3y = -11Subtract 4 on both sides: -3y = -15Divide -3 on both sides: y = 5Can you leave a radical in the denominator?
Yes
No
Answers

no
Step-by-step explanation:
Traditionally, a radical or irrational number cannot be left in the denominator (the bottom) of a fraction. When a radical does appear in the denominator, you need to multiply the fraction by a term or set of terms that can remove that radical expression.

The solutions to the blanks are Circle, y-axis and 5 units, respectively.
What is the equation of the circle?The equation of the circle whose center is coordination at (h,k) and radius is r will be
(x -h)² +(y -k)² = r²
where (h,k) is the coordination of its center and r is the radius.
We have,
r = 5 sinΘ
So,
When the center of the circle is at origin (0,0);
Then x² + y² = r²
So,
We have, r = 5 sinΘ
So,
For 0 ≤ θ ≤ π,
The circle is developed above the x-axis and symmetrical about the y-axis (θ=π/2)
The circle has a radius of 5/2, centered at (0, 5/2), so the diameter is 5 units.
And hence the greatest distance between any two points on a graph is 5 units.
Therefore, the solutions to the blanks are Circle, y-axis, and 5 units, respectively.

Answer:
22.6
Step-by-step explanation:
The cos of any angle is its adjacent over its hypotenuse:
cos 37 = 17.3 / x
We can multiple both sides by x to get x * cos 37 = 17.3 and then we can divide both sides by cos 37 to get x by itself:
x = 17.3 / cos 37
So solving for x, x is equal to about 22.6

What is the constant term in the polynomial expression -7x2 + 32x + 240, and what does it represent?
Answers
Answer:
The constant term is 240. A constant term represents a fixed value. In other words, a term that does not change.
Step-by-step explanation:
In the polynomial expression given, the first and second terms are dependent of x, which means whatever the value x is, the terms will change. For example, if x = 2, we have -7(4) + 32(2) + 240. As you can see the constant never changes because it does not rely on a variable; it is constant.

"Find the error & explain why it is wrong."

The error is in the last step. In Step D, we see that we're supposed to subtract the second part from the first part. We also see we have the terms 2x-8 in the numerator on the right. Since we're subtracting, the expression should actually be -2x +8. 3 -2x +8 should be -2x +11 which is not the numerator in Step E so the last step is wrong.

What is the approximate surface area of the largest sphere that can fit inside a cube with a side length of 18 inches?
1018 square inches
1356 square inches
4069 square inches
6104 square inches
Answers
Answer:
A.) 1018 square inches
Step-by-step explanation:
The largest sphere will have a diameter equaling the length of the cube (see picture).
If the side length of the cube is 18 inches, the diameter of the sphere is also 18 inches. Use the surface area formula for a circle:
[tex]SA=4\pi r^2[/tex]
For this formula, we need the radius of the sphere. Divide the diameter by 2:
[tex]\frac{18}{2}=9[/tex]
The radius is 9 inches. Plug this into the equation:
[tex]SA=4\pi *9^2[/tex]
Simplify the equation:
[tex]SA=4\pi *81\\\\SA=324\pi \\\\SA=1017.87[/tex]
Round the result to the nearest whole number:
[tex]1017.87[/tex] → [tex]1018[/tex]
The surface area is 1,018 inches².
:Done
Picture:
In a 2D version, we can clearly see that if the circle fits snuggly inside of the square, the diameter of a sphere is the same as the length of a side of the cube.
