The gradient is 2
Answer:
gradient = [tex]\frac{1}{2}[/tex] , y- intercept = - 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c is the y- intercept )
given
x - 2y = 8 ( subtract x from both sides )
- 2y = - x + 8 ( divide through by - 2 )
y = [tex]\frac{1}{2}[/tex] x - 4 ← in slope- intercept form
with gradient m = [tex]\frac{1}{2}[/tex] and y- intercept c = - 4
5. One positive number is 3 greater than another positive number. When 12 is added to the square of the smaller number, the result is the same as four times the larger number. Find the two numbers.
Answer:
4, 7
Step-by-step explanation:
x = y + 3
y² + 12 = 4x
using the first equation in the second
y² + 12 = 4(y + 3) = 4y + 12
y² = 4y
y = 4
x = y + 3 = 4 + 3 = 7

Answers:
Choice C) the number of hours the barn is rentedChoice B) 10Choice A) the hourly rateChoice C) 550Choice B) the base fee to rentChoice A) The variable yChoice D) total amount charged========================================================
Explanation:
The equation is y = 10x+550
If x = 0, then it leads to y = 550. This is the smallest amount paid, and it's the base fee. Think of it like the fee to get in the door. This is the y intercept of the equation.
On top of this base fee is the $10 per hour fee for utilities. Each time an hour goes by, add on another extra $10. So we attached x to this to reflect what's going on. This is the slope of the equation, aka rate of change.
It might be helpful to compare y = mx+b to y = 10x+550
m = 10 = slope = how things change
b = 550 = y intercept = starting point
----------
Example:
Let's say you rented the barn for 2 hours.
That means x = 2 and 10x = 10*2 = 20 extra dollars is added on top of the base fee of $550
total = 20+550 = 570
This is what the steps could look like when plugging in x = 2
y = 10x+550
y = 10*2 + 550
y = 20 + 550
y = 570
Therefore, renting the barn for x = 2 hours leads to a total cost of y = 570 dollars.

OD. 400
OE. 96

Answer:
C. 20
Step-by-step explanation:
Use the Pythagorean theorem which is [tex]a^{2} +b^{2} =c^{2}[/tex].
[tex]a^{2}[/tex] and [tex]b^{2}[/tex] are the sides of the triangle squared, AB and AC. [tex]c^{2}[/tex] is the hypotenuse (the slanted side of the triangle) or BC.
So, [tex]12^{2} + 16^{2} =400^{2}[/tex]. Then you square root 400 to get your answer.
[tex]\sqrt{400}[/tex] = 20.
20 is your answer.

What are the coordinates of the point on the
directed line segment from (4, 3) to (9, 8) that
partitions the segment into a ratio of 2 to 3?
The required coordinates are (6, 5).
Let A denotes the point (4, 3), and B denotes the point (9, 8).
Let C denote the point which divides the line segment AB in the ratio of 2:3.
The distance between A(4, 3) and B(9, 8) is given by
AB = √{(x₂ - x₁)² + (y₂ -y₁)²}
= √{(9 - 4)² + (8 - 3)²
= √{5² + 5²}
= √(2×5²)
= 5√2
We have AC + BC = AB
AC and BC are in the ratio 2:3.
Therefore 2x + 3x = AB
⇒5x = 5√2
⇒x = √2.
Therefore, AC = 2√2 and BC = 3√2.
Using the distance formula,
AC = √{(x - 4)² + (y - 3)²}
⇒ 2√2 = √{(x - 4)² + (y - 3)²}
⇒ √(2² + 2²) = √{(x - 4)² + (y - 3)²} (taking the 2 inside the square root.)
⇒ x - 4 = 2 ⇒ x = 6
⇒ y - 3 = 2 ⇒ y = 5.
Therefore the required coordinates are (6, 5).

Find a vector function, r(t), that represents the curve of intersection of the two surfaces. the paraboloid z = 9x2 y2 and the parabolic cylinder y = 2x2
The vector function is, r(t) = [tex]\bold{ < t,2t^2,9t^2+4t^4 > }[/tex]
Given two surfaces for which the vector function corresponding to the intersection of the two need to be found.
First surface is the paraboloid, [tex]z=9x^2+y^2[/tex]
Second equation is of the parabolic cylinder, [tex]y=2x^2[/tex]
Now to find the intersection of these surfaces, we change these equations into its parametrical representations.

There are 30 bags of shredded cheese.
Let 'x' be the quantity of cheese in each bag. Then,
The total quantity of cheese in 30 bags = 30x
Number of plates = 20 plates
We need to determine the quantity of cheese put on each plate so that each plate has the same amount of shredded cheese.
For this we just need to divide the total amount of shredded cheese by the number of plates.
The equal amount of cheese in each of 20 plates = 30x/20

There are two squares with the same side lengths scaled copies of one another explain your reasoning
A square is a rectangle with equal lengths on each side. The two squares with the same length side will be lengths scaled copies of one another.
A rectangle whose all sides are equal is called a square.
A square is always a rectangle, parallelogram, and a quadrilateral but its reverse statement may or may not be true.(ie it is not always necessary that a rectangle is a square or a parallelogram is a square).
As it is known that two squares are always similar to each other which is because all the angles of a square are always 90°. Therefore, any two squares are always similar to each other.
Now, as it is given that the two square have the same length sides. Therefore, the two squares with the same length side will be lengths scaled copies of one another. This is because all the sides are equal and all the angles are equal.
Hence, the two squares with the same length side will be lengths scaled copies of one another.

find the perimeter of the polygon with vertices U (-2,4) V (3,4) and W (3,-4)
So the perimeter of the polygon with vertices U (-2,4) V (3,4) and W (3,-4) is Perimeter = 22.434
Perimeter of any close shape is the total length of the boundary of any closed shape.
We have been given vertices of polygon that are U (-2,4) V (3,4) and W (3,-4)
To find the perimeter we need to find the length of all three sides, and we do that by finding the distance between the points that form the sides:
The formula for the distance between two points is:
[tex]$d=\sqrt{\left(x_1-x_2\right)^2+\left(y_1-y_2\right)^2}$[/tex]
side UV:
[tex]$U V=\sqrt{(-2-3)^2+(4-4)^2}=5$[/tex]
side VW:
[tex]$V W=\sqrt{(3-3)^2+(4-(-4))^2}=8$[/tex]
side UW:
[tex]$U W=\sqrt{(-2-3)^2+(4-(-4))^2}=9.434$[/tex]
So the perimeter is:
P=UV+VW+UW
[tex]$P=5+8+9.434=22.434$[/tex]
