Draw the two planes determined by the following equations:
2x+3y-z=12
2x-4y+z=8
Both the planes of the given equations,
2x+3y-z=12 (1)
2x-4y+z=8 (2)
They have been drawn in a three-dimensional plane, and the images are attached below.
Tell whether each equation is in slope-intercept, point-slope, or standard form.
d. y-3=4 x
y-3=4 x is in point-slope form, it is neither in slope-intercept form nor standard form.
What is a slope of line?A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.
The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.
Therefore,
m = y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.
Be aware that tan ∅ = y/x
We also refer to this tan as the line's slope
We know that point-slope form = y₂ - y₁ = m(x₂ - x₁)
the equation looks like this in point-slope form ⇒ y-2= 4(x-0)
Here, the points are (x, y) and the points the line is passing through is
(0, 2)
y-2= 4(x-0) is in point-slope form, it is neither in slope-intercept form nor standard form.

Find the percent of the given number. 65 % of 360
A percentage in mathematics is a number or ratio that can be expressed as a fraction of 100.
The percent of the given number 65 % of 360 is 234.
What is meant by percentage?A percentage in mathematics is a number or ratio that can be expressed as a fraction of 100. The term percent comes from the Latin "per centum" which means per hundred. The symbol percentage is used to represent percentage.
Let the equation be 65 % of 360
Percentage = (value/total value) × 100 %.
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
65 % of 360 = 65/100 of 360
65/100 × 360 = 234
Therefore, the percent of the given number 65 % of 360 is 234.

Three angles fit around a .2 of the angles are 115° and 53° work out the size of the third angle which of the word below describes the third angle right angle obtuse angle reflex angle or acute angle
Three angles fit around a point, two of the angles are 115° and 53° , then the size of third angle would be 192° and it would be a reflex angle.
The sum of the angles around a point is 360 °
If the two angles are 115° and 53° , the sum of the two angles would be 168°
If we reduce the sum of the two angles from the total 360° , we get the size of third angle as 192°
As the size of third angle is more than 180° , so the name of the third angle is reflex angle because right angle is measured 90° , obtuse angle is measured more than 90° but less than 180° , reflex angle is measured more than 180° but less than 360° and acute angle is measured less than 90 °

We have to find that the distance between two bodies.
So, For this purpose, we know that the
A force is a push or pull upon an object resulting from the object's interaction with another object.
From the given information:
If the force of attraction is 64 pounds when the distance between the bodies is 9 feet
Then
F1 =64 pounds, r1 = 9 ft
F2 = 36 , r2 = ?
The gravitational force of attraction is inversely proportional to the square of distance between the two bodies.
So, F2 / F1 = r1^2 / r2^2
36 / 64 = 9 / r2
r2 = 0.56*9
r2 = 5.06.

Find the equation of the axis of symmetry of the following parabola algebraically.
y=2x^2-24x+86y
The equation of the axis of symmetry is x = 6
How to find the equation of the axis of symmetry?The equation of the parabola is given as:
y = 2x^2 - 24x + 86
Differentiate the equation of the parabola
So, we have
y' = 4x - 24
Set the differentiated equation of the parabola to 0
So, we have
4x - 24 = 0
Add 24 to both sides of the differentiated equation of the parabola
4x = 24
Divide both sides of the differentiated equation of the parabola by 4
x = 6
This represents the the axis of symmetry
Hence, the equation of the axis of symmetry is x = 6

Direct variation is a sort of proportionality in which one quantity fluctuates directly in response to a change in another number.
it is denoted as y = kx (where is the constant)
it is not directly varied if y has two x solution.
How to solve an equation?To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
