find the quadratic function for f(x) = ax2 + bx +c and a=1, b=4, c= 3
Answer:
f(x) = g(x - 3)(x - 5) for some g
f(x) = g(x^2 - 8x + 15)
Substitute (4, -1) for (x, f(x)) and solve for g.
-4 = g(4^2 - 8(4) + 15)
-4 = g(-1)
g = 4
f(x) = 4x^2 - 32x + 60

On Monday, a local hamburger shop sold a combined total of 408 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Monday?
Answer:
I'm pretty sure the answer would be 102
Step-by-step explanation:
you divide 408 by 4 because the cheeseburgers sold 3x as much as the hamburgers.

What is the equation of the line parallel to
3x + 2y = 8 and passes through the point
(4, -3)?
(4,-3)=1,x+y so easy broooooo
The equation of the line which is parallel to3x + 2y = 8 and passes through the point (4, -3) is y = -1.5x + 3
How are parallel straight lines related?Parallel lines have same slope, since slope is like measure of steepness and since parallel lines are of same steepness, thus, are of same slope.
How to get the slope intercept form of a straight line equation?If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:
[tex]y = mx +c[/tex]
Let the straight line parallel to the line [tex]3x + 2y = 8[/tex] be [tex]y = mx +c[/tex]
Converting first line in slope intercept form, we get:
[tex]3x + 2y = 8\\\\y = -\dfrac{3x}{2} + 4\\\\y = -1.5x + 4[/tex]
Thus, the slope of the first line is -1.5
The second line being parallel to this, will have same slope. Thus, we get[tex]m = -1.5[/tex]
Thus, the equation of the second line is;
[tex]y = -1.5x +c[/tex]
Now, since it passes through (4,-3), therefore, putting x = 4 and y = -3 should satisfy the equation.
Thus, we get:
[tex]y = -1.5x +c\\\-3 = -1.5(4) + c\\c = 6-3 = 3[/tex]
Thus, the y-intercept of this line is c = 3
Thus, the equation of the second line is: y = -1.5x + 3
Thus, the equation of the line which is parallel to3x + 2y = 8 and passes through the point (4, -3) is [tex]y = -1.5x + 3[/tex]
The graph of this equation is given below.

What is the value of the larger zero of the function defined by x²+4x-252?
A. 9
B. 12
C. 14
D. 21
Answer:
C
Step-by-step explanation:
The equation will become
[tex] {x}^{2} + 4x - 252 = 0[/tex]
If I substitute 14 into the position of x
[tex] {14}^{2} + 4(14) - 252 = 0[/tex]
[tex] {14}^{2} + 4(14) = 252 \\ 196 + 56 = 252[/tex]
I get 252 exactly

How do you find Median? I completely forgot
Answer:
Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

In the same set of 1,000 integers from 1 to 1,000, an integer chosen at random on a single trial should be an integer from 1 to 25 about 25 out of every 1,000 trials, or one out of every 40 integers selected. How many integers between 1 and 25 would you expect to appear in a sample of 80 trials?
A. A sample of 80 integers would be expected to have no integers from 1 to 25.
B. A sample of 80 integers would be expected to have two integers from 1 to 25.

What would be the volume of the box if it’s factor is scaled down by 1/10? The volume is 130 inches
Answer:
27 units (whatever units the figure was measured in)
Step-by-step explanation:
Volume is length times width times height. So, you would need to do 9 times 3 (27) times 10 (270). Then, you would divide by 10, because it is scaled down by 1/10, leaving you with 27.

Answer:
b=1/5 so basically b=1
Step-by-step explanation:
-10b--16b+3b-17b=-8
Add similar elements
-10b-16b+3b-17b=-40b
-40b=-8
Divide both sides by -40
-40b/-40=-8/-40
Simplify;
40b/40
=b
Simplify;
-8/-40
=8/40
Cancel the common factor 8
b=1/5
