Answer: f(x) = 3x² - 15x + 12
Step-by-step explanation:
Given f(x) has roots x = a and x = b, then
(x - a) and (x - b) are the factors
f(x) is then the product of the factors
f(x) = a(x - a)(x - b) ← where a is a multiplier
Given roots are x = 4 and x = 1, then
(x - 4) and (x - 1) are the factors
With a = 3, then
f(x) = 3(x - 4)(x - 1) ← expand factors using FOIL
= 3(x² - 5x + 4) ← distribute
= 3x² - 15x + 12

What is y= 4/5x+2 written in standard form?
Answer:
[tex]-\frac{4}{5}[/tex]x + y = 2
Step-by-step explanation:
Standard Form: Ax + Bx = C
y = [tex]\frac{4}{5}[/tex]x + 2
[tex]-\frac{4}{5}[/tex]x + y = 2
Answer:
4/5x-y=-2
Step-by-step explanation:
standard form
Ax+By=C.
y= 4/5x+2
subtract 4/5x from both sides
-4/5x+y=2
multiply both sides by negative 1
4/5x-y=-2

What is range, domain, and is this graph a function?
Answer:
The domain is all x-values or inputs of a function and the range is all y-values or outputs of a function. When looking at a graph, the domain is all the values of the graph from left to right. The range is all the values of the graph from down to up.

b) The sum of the ages of the father and son is 44 years. After 8 years, the age of
father will be twice the age of the son. Find their present ages,
Let the present age of father = x years
and the present age of son = y years
according to the first condition
x + y =44 ........(i)
according to the second condition
x+8 = 2(y+8)
or x+ 8 = 2y + 16
or x- 2y = 8 ............(ii)
solve the equation (i) & (ii) we get
x + y =44
x- 2y = 8
••••••••••••••••••••••••
3y = 36
or y = 12
put the value of y in equation (i), we get
x + 12 =44
or x = 32
so the present age of father = x =32 years
and the present age of son = y = 12 years.
Hope it helps you please mark as brainlistWhat is the Y and x intercept of 9X-6Y= 72
Answer: The y-intercept is -12
The x-intercept is 8
Step-by-step explanation: Factor out 3
Divide all by 3 to simplify.
9x - 6y = 72 is equivalent to
3x - 2y = 24
At this point, you can substitute 0 for x and solve for y
3(0) -2y = 24. -2y/-2 = 24/-2
y = -12
And substitute 0 for y and solve for x.
3x -2(0) = 24. 3x/3 = 24/3
x = 8
OR Change to slope intercept form:
y = mx + b. b is the y intercept.
-2y = -3x + 24. Solve for y.
Divide all by-2
y = 3x/2 - 12.
The y-intercept is -12
To find the x-intercept, substitute 0 for y and solve for x.
0 = 3x/2 -12 Add 12 to both sides.
12 = 3x/2. Multiply both sides by 2/3
8 = x
The x-intercept is 8
Which of the following rules describes the function graphed below
A) output = input
B) Output = 2•Input - 1
C) Output = Input + 2
D) Output = 3 • Input - 2
Select the slope-intercept form of an equation for a line with y-intercept -2 and slope 6.
Answer:
y = 6x - 2
Step-by-step explanation:
slope intercept form is y = mx + b
m = slope
b = y-intercept
They give us the slope (m) which is 6 and the y-intercept (b) which is -2. PLug it into the equation
y = mx + b
y = 6x - 2

Explain whether 11t - 3t is equivalent to 3t - 11t. please help
It is not.
There are two ways to deal with this.
First is to separate them into expressions.
11t - 3t is made up of 11t and -3t
3t - 11t is made up of 3t and -11t
As you can see the negative sign are different from each expressions, therefore they are different.
Another way to see it is to solve them.
11t - 3t = 8t
3t - 11t = -8t
The answers are not = so they are not equivalent to each other.

The parallelogram is shown below I have an area of 135 units. Find the missing base
Answer:
9
Step-by-step explanation:
The area of a parallelogram is base * height.
The area is given as 135
The height is given as 15
You do not need to use 17
Area = base * height Substitute
135 = base * 15 Divide by 15 on both sides
135/15 = base*15/15
base = 9

Answer:
x = 3 and 1/3
Step-by-step explanation:
First, get the interior angle of the 114 by subtracting 114 from 180, and you should get 66. Next, add the two known interior angles of 66 and 64 to get 130. With the knowledge that the 3 interior of all triangles add up to 180, you should know that 3x-40 is equal to 180 -130, or 50. With 3x+40 = 50, start by subtracting 40 from both sides for 3x = 10. Finally, divide both sides by 3 to get x = 3 and 1/3
