Which polynomial function could be represented by the graph below?
On a coordinate plane, a parabola opens up. It goes through (2, 0), has a vertex at (3, negative 3), and goes through (4, 0).
Answer:
f(x) = 3(x - 3)^2 - 3Step-by-step explanation:
Let the base function be
f(x) = ax^2It has the vertex at (3, -3), so it is translated 3 units right and 3 units down:
f(x) = a(x - 3)^2 - 3It has zero's at (2, 0) and (4, 0)
Substitute and solve for a:
a(x - 3)^2 - 3 = 0a(2 - 3)^2 = 3a = 3or
a(4 - 3)^2 - 3 = 0a = 3So the function is:
f(x) = 3(x - 3)^2 - 3See the attached
Answer:
f(x) = 3x2 – 18x + 24

y = 5x - 6&y= -4x + 3
Use the Equal Values Method to solve for x and y
Answer: x = 1 and y = -1
Step-by-step explanation:
Since both equations are equal to y, that means the equations are both equal to each other
5x - 6 = -4x + 3
Solve for x how you would traditionally do it with any other one-variable equation
9x = 9
x = 1
Plug the now known x value into either equation and you will get your y value.
5(1) - 6 = -1
-4(1) + 3 = -1

In a right triangle ABC, C is the right angle. What does sinB equal?
A)
cos (90°-B)
B)
sin (90°-B)
C)
cos B
D)
Both A and C are correct
9514 1404 393
Answer:
A) cos (90°-B)
Step-by-step explanation:
The sine of an angle is equal to the cosine of its complement.
sin(B) = cos(90° -B)

If triangle HBN ~ triangle LYR, find the value of x.
Answer:
x = 13
Step-by-step explanation:
BH / YL = HN / LR
28 / 21 = 3x-7 / x+11
cross-multiply:
4x + 44 = 9x - 21
-5x = -65
x = 13
Answer:13

A pet store has 8 cats. Here are their weights (in pounds).
6, 14, 5, 8, 11, 10, 5, 10
Find the mean weight of these cats.
If necessary, round your answer to the nearest tenth.
Answer:
The mean is 8.6
Step-by-step explanation:
You want to add all of the weight together, then you want to divide that number by how many cats there were.
I need help fast plz

pls helpppp asapppp with the question above
Answer:
the answer should be B
Step-by-step explanation:
i do apologize if its wrong im like 99.9% sure it correct
Answer:
0
Step-by-step explanation:
4(m+2) = -4(m-2)
by dividing over 4 :
m+2 = -1(m-2)
= m+2 = -m+2
by subtracting 2 :
m = -m
by adding "m" :
2m = 0
So
m = 0

y =
x +
Answer:
[tex]y = 7x [/tex]
Step-by-step explanation:
To find the slope, which is
[tex] \frac{rise}{run} [/tex]
find how high up the y value goes before it intersects the x line at a specific point. It seems that they intersect at (70,10) which would be 70/10 or 7/1. 7/1 is just 7 so the slope of it is just that, 7. As for finding B, look at where the line starts, of it's above or below 0, then you would add or subtract whatever number it starts at (subtract for negative, add for positive). In this case it seems that the intercept is right at 0 so you would neither add or subtract anything. :)
20y-10x=5 in slope intercept form can you explain the steps
Given:
The equation is
[tex]20y-10x+5[/tex]
To find:
The slope intercept form of the given equation.
Solution:
The slope intercept form of a linear equation is
[tex]y=mx+b[/tex]
Where, m is slope and b is the y-intercept.
We have,
[tex]20y-10x=5[/tex]
We need to isolate y. Add 10x on both sides.
[tex]20y-10x+10x=5+10x[/tex]
[tex]20y=5+10x[/tex]
Divide both sides by 20.
[tex]\dfrac{20y}{20}=\dfrac{5+10x}{20}[/tex]
[tex]y=\dfrac{5}{20}+\dfrac{10x}{20}[/tex]
[tex]y=\dfrac{1}{4}+\dfrac{x}{2}[/tex]
[tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex]
Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex].
