The quadratic equation that has a root of 6 and 2 is x^2 - 8x + 12 = 0
How to determine the quadratic equation?The roots are given as:
x = 6 and x = 2
Rewrite as:
x - 6 = 0 and x - 2 = 0
Multiply both equations
(x - 6)(x - 2) = 0 * 0
Evaluate the product
x^2 - 6x - 2x + 12 = 0
Evaluate the difference
x^2 - 8x + 12 = 0
Hence, the equation that has a root of 6 and 2 is x^2 - 8x + 12 = 0

can you help me figure of the value of y?and possible x (I think I got it)
The values of x and y from the figure are 22.5 and 10 respectively
Vertical anglesThe angles that meet at a point X are equal and vertically opposite
From the diagram shown
6x - 5 = 8x - 50
6x - 8x = -50 + 5
-2x = -45
x = 22.5
Similarly
2y + 30 = 3y + 20
2y - 3y = 20 - 30
-y = -10
y = 10
Hence the values of x and y from the figure are 22.5 and 10 respectively

Let's solve ~
Since the two lines intersects each other we can conclude that :
6x - 5 = 8x - 50and
2y + 30 = 3y + 20[ That's because they form vertical opposite angle pair ]
So, let's solve for x and y ~
[tex]\qquad \sf \dashrightarrow \:6x - 5 = 8x - 50[/tex]
[tex]\qquad \sf \dashrightarrow \:8x - 6x = - 5 + 50[/tex]
[tex]\qquad \sf \dashrightarrow \:2x = 45[/tex]
[tex]\qquad \sf \dashrightarrow \:x = \dfrac{45}{2} [/tex]
[tex]\qquad \sf \dashrightarrow \:x = 22.5[/tex]
And
[tex]\qquad \sf \dashrightarrow \:2y + 30 = 3y + 20[/tex]

Lakeridge health oshawa is a 423 beds hospital with 463 doctors and 4058 staff comprised of nurses and technologists. it is planning to open another 35-bed wing. assuming the same proportionate staffing levels, how many more doctors will need to be hired?
The number of doctors that would be needed for the 35-bed wing is 38.
How many more doctors are needed?The first step is to determine the number of doctors needed for one bed : 463 / 423
The second step is to multiply the ratio gotten in the first step by the number of beds in the new wing: (463 / 423) x 35 = 38.21 = 38

What is the y-intercept of the function f(x) = -2/-9x+1/3?
Answer:
b = 1/3
Step-by-step explanation:
The general structure of equations in slope-intercept form is:
y = mx + b
In this form, "m" represents the slope and "b" represents the y-intercept.
The given equation is already in slope-intercept form. In other words, you have already been given "m" and "b". Therefore, the value which corresponds with the y-intercept is (1/3).
f(x) = mx + b
f(x) = -(2/9)x + 1/3

x = 200° (arc measure = central angle measure)The inscribed angle y is half of the arc length xy = 1/2xy = 1/2(200°)y = 100°Q10
x + 112 = 180x = 68°y + 81 = 180y = 99°Answer:
9. x = 200 and y = 100
10. x = 68 and y = 99
Step-by-step explanation:
Question 9
The measure of an arc is the measure of its central angle.
⇒ x = 200
This is a non-cyclic quadrilateral as not all its vertices touch the circumference of the circle.
The angle at the center is twice the angle at the circumference.
⇒ y = 200 ÷ 2
⇒ y = 100
Question 10
This is a cyclic quadrilateral as all its vertices touch the circumference of the circle.
The opposite angles in a cyclic quadrilateral add up to 180°.
⇒ x + 112 = 180
⇒ x = 68
⇒ y + 81 = 180
⇒ y = 99

Using proportional reasoning, about how many students out of the 2,000 would you expect to select an orange as their favorite fruit?
Answer:
almost 567 students
Step-by-step explanation:
all fruits = 23+18+34+27+18 = 120
possibility of selecting an orange as favourite fruits by one student = 34/120 = 17/60
possibility of selecting an orange as favourite fruits by 2000 students = 17/60×2000 =1700/3 = 566.6666...=567 students

which of the following equations will produce the graph shown below?

What is an equation of a circle?A circle can be characterized by its center's location and its radius' length. Let the center of the considered circle be at (h,k) coordinate and the radius of the circle be 'r' units. Then, the equation of that circle would be:
(x-h)² + (y-k)² = r²
The given graph is the graph of a circle that has its origin at (0,0) and has a radius of 4 units, therefore, the equation will be,
(x-0)² + (y-0)² = 4²
x² + y² = 16
Multiply both the sides of the equation by 2,
2x² + 2y² = 32
Hence, the correct option is A.

a translation 3 units up and 1 unit left and then a 180° rotation about the origin
a 90 degree clockwise rotation about the origin and then a reflection over the Y axis
a 90° counterclockwise rotation about the origin and then a reflection over the X axis
A translation through you to down and one unit right and then I 108° rotation about the origin
The correct transformation is a rotation of 180° around the origin followed by a translation of 3 units up and 1 unit to the left.
Which transformation is used to get A'B'C'?
To analyze this we can only follow one of the vertices of the triangle.
Let's follow A.
A starts at (3, 4). If we apply a rotation of 180° about the origin, we end up in the third quadrant in the coordinates:
(-3, -4)
Now if you look at A', you can see that the coordinates are:
A' = (-4, -1)
To go from (-3, -4) to (-4, -1), we move one unit to the left and 3 units up.
Then the complete transformation is:
A rotation of 180° around the origin, followed by a translation of 3 units up and 1 unit to the left.
