Mathieu is finding the x-intercepts of the function f(x) = x2 4x 3. his work is shown below. 0 = x2 4x 3 0 = (x 3)(x 1) x 3 = x 1 x = x – 2 0 = –2 there are no x-intercepts. which error did mathieu make? he factored incorrectly. he did not use the constant as the x-intercept. he set the factored expressions equal to each other. he incorrectly solved the equation x 3 = x 1.
He set the factored expressions equal to each other. instead of setting them equal to zero
What are quadratic equations?The name Quadratic comes from "quad" meaning square because the variable gets squared (like x2). It is also called an "Equation of Degree 2
The given solution of the quadratic equation in the question is
[tex]f(x) = x^2 + 4x + 3.[/tex]
His work is shown below.
[tex]0 = x^2 + 4x + 3[/tex]
[tex]0 = (x + 3)(x + 1)[/tex]
Here is where we use the zero product property
x+3 = 0 x+1 =0 We do not set them equal to each other
Hence He set the factored expressions equal to each other. instead of setting them equal to zero

13 less than the product of 4 and a number, n, is 5
The value of n which makes the statement "13 less than the product of 4 and a number, n, is 5" true, is 4.5.
How to write algebraic expression?Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
The statement given in the problem is "13 less than the product of 4 and a number, n, is 5".
Here, the 13 less than the product of n and 4 (n×4-13) is equal to the number 5. In the equation form,
[tex]4\times n-13=5[/tex]
Add number 13 both side and simplify it further,
[tex]4\times n-13+13=5+13\\4n=18\\n=\dfrac{18}{4}\\n=4.5[/tex]
Thus, the value of n which makes the statement "13 less than the product of 4 and a number, n, is 5" true, is 4.5.

Step-by-step explanation:
put these into slope intercept form
x + 3y ≤ 8
x + y ≥ 2
Slope intercept form is y = mx + b
[a] x + 3y ≤ 8 becomes y ≤ -[tex]\frac{1}{3}[/tex]x + [tex]\frac{8}{3}[/tex]
We subtract x from both sides of the equation.
Then we divide both sides of the equation by three.
x + 3y ≤ 8
3y ≤ -x + 8
y ≤ -[tex]\frac{1}{3}[/tex]x + [tex]\frac{8}{3}[/tex]
[b] x + y ≥ 2 becomes y ≥ -x + 2
We subtract x from both sides of the equation.
x + y ≥ 2
y ≥ -x + 2
Find an exponential function of the form y = ab* that passes through the points (0,4)
and (2, 100).
Oy=5-4x
Oy=4.5*
Oy-4-2*+84
Oy-25-2x
Answer:
2nd option
Step-by-step explanation:
given an exponential function in the form y = a[tex]b^{x}[/tex]
to find a and b use the coordinate points it passes through
using (0, 4 ) , then
4 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , that is
a = 4 , so
y = 4[tex]b^{x}[/tex]
using (2, 100 )
100 = 4b² ( divide both sides by 4 )
25 = b² ( take the square root of both sides )
[tex]\sqrt{25}[/tex] = b , that is
b = 5
then exponential function is
y = 4 . [tex]5^{x}[/tex]

t takes 12 hours for half of the He in a container to leak out. If the same container is refilled with Ne, how long will it take for half of the Ne to leak out
The time taken by the Ne to come out of the container will be 26.83 hours
What will be the time?Here it is given in the question that it takes 12 hours for half of the He in a container to leak out If the same container is refilled with Ne then time taken by the Ne gas to leak will be calculated from the formula
[tex]\dfrac{V_{He}}{t_{He}}\times \dfrac{t_{Ne}}{V_{Ne}}=\sqrt\dfrac{M_{Ne}}{M_{He}}[/tex]
Since the volume of both the gases will be same so
[tex]V_{He}=V_{Ne}[/tex]
[tex]\dfrac{t_{Ne}}{t_{He}}=\sqrt5[/tex]
[tex]t_{Ne}=12\times \sqrt5[/tex]
[tex]t_{Ne}=12\times 2.236[/tex]
[tex]t_{Ne}=26.83\ hours[/tex]
Hence the time taken by the Ne to come out of the container will be 26.83 hours

Explanation:
Through trial and error, we can set up these equations
4^5 = 10242^10 = 102432^2 = 1024This shows that choices A, C and D are eliminated. This is because 5, 10 and 32 all can work as either x or y in x^y = 1024, and that the other value is some other integer.
On the other hand, x = 16 doesn't work and neither does y = 16 if we wanted the other value to be an integer.
Solving x^16 = 1024 leads to approximately x = 1.5422 when we focus on the positive real number solution. This isn't an integer, so x^16 = 1024 doens't have any integer solutions.
Solving 16^y = 1024 leads to a similar situation as described in the previous paragraph. It doesn't have any integer solutions either (instead the value is y = 2.5)
So we have a few ways of arriving at why choice B is the final answer.

Bob owns a watch repair shop. He has foundthat the cost of operating his shop is given byc=2x2-192x+54, where c is cost and x is thenumber of watches repaired. How manywatches must he repair to have the lowestcost?
The solution for the quadratic equation, c(x) = [tex]2x^{2} -192x+54[/tex] is +48.
Bob must repair 48 watches to have the lowest cost.
What is axis of symmetry?
The axis of symmetry formula uses the standard form of the quadratic equation as well as the vertex form.
We have, c(x) = [tex]2x^{2} -192x+54[/tex]
As we know the axis of symmetry, using the formula:
x = [tex]\frac{-b}{2a}[/tex]
In the above equation a = 2; b = -192
x = [tex]\frac{-(-192)}{2 * 2}[/tex]
x= [tex]\frac{192}{4}[/tex]
x = +48
Hence, the number of watches for lowest cost bob must sold is 48 watches.

Answer:
[tex]6x[/tex]
Step-by-step explanation:
Hey there!

After splitting:
[tex]\frac{6*x*x}{x}[/tex]
Now, we can cross out two of the x values
[tex]\frac{6*x}{1}[/tex]
This is also seen as
[tex]6*x[/tex]
Which simplified is our answer
So the fraction [tex]\frac{6x^2}{x}[/tex] can be re-written or solved as, [tex]6x[/tex]
Answer:
[tex]\frac{6x^{2}}{x} =6x[/tex]

What number is bigger 18.84 or 28.8
Answer:
In terms of decimal places, 18.84 is bigger because of the hundredths place(4). In terms of whole numbers, 28.8 is bigger.
Answer: 28.8
Step-by-step explanation:
If you look at the first digit on the left in the number 28.8, which is 2, then you look at the first digit of 18.84, which is 1, you can see that 2 is larger than 1, so therefore 28.8 is larger.
