Which of the following is the minimum value of the equation y = 3x2 - 4x - 2?
Answer: 3x
Step-by-step explanation:
*Remember BIDMAS*
b- brackets i- Indices (exponents) d- division m- multiplication a- addition s- subtraction
(*Reminder* exponents can be written on a keyboard like 2 squared is 2^2)
you need to follow these steps to be able to solve any equation
if there is no brackets like yours then add to make it easier
3x^2 - 4x - 2 = (3x^2) - 4x - 2
From the steps I showed you indices is first so 3x multiplied by 3x is 9x
now there is nothing left except for subtraction so solve from left to right always so 9x - 4x - 2 is 5x then 5x - 2 is 3x, x doesn’t change or gets subtracted.
i hope it helped :)

Step-by-step explanation:
We first have to create the roots of the graph. This can the done by creating factors based on the x intercepts as shown in the equation above. We have to make sure we change the signs of the x intercepts in order to create zeros.
We then have to square (x+0) because it does not completely cross the x axis. Finally we we multiply everything by -1 because the graph is starting from the top.
From the graph , we can see that the line of the graph passes through the points ,
(0,0)
(-1,0)
( 2, 0 )
(3,0)
These are the roots of the equation. The point on which the graph cuts the x axis are the roots of the graph . Here since the graph cuts x axis 4 times , it has 4 roots as ,
-1
2
0
3
Equation of the graph :-
[tex]\implies f(x) = x ( x +1)(x-2) ( x-3) [/tex]

Answer:
[tex]y=\frac{5}{6}x+2\frac{2}{3}[/tex]
Step-by-step explanation:
From the point (-2,1) to the point (4,6)
there is a [tex]\frac{rise}{run}[/tex] of [tex]\frac{5}{6}[/tex], or a slope of [tex]\frac{5}{6}[/tex]
[tex]rise=[/tex] the change in y
[tex]run=[/tex] the change in x
To get the y-intercept we just have to use the formula: [tex]b=y-mx[/tex]
[tex]b=[/tex] y-intercept
[tex](x,y)=[/tex] point on the line
[tex]m=[/tex] slope
[tex]b=1-(\frac{5}{6})(-2)[/tex]
[tex]b=1+\frac{5}{3}[/tex]
[tex]b=2\frac{2}{3}[/tex]
So the equation of the line is: [tex]y=\frac{5}{6}x+2\frac{2}{3}[/tex]

What is 57 x 4?
Enter your answers in the boxes to complete the area model.
Answer:
200 + 28= 228
..................
The values of the numbers in the boxes is 57 x 4 = 200 + 28 = 228
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first number be represented as p
where the value of p = 57
Let the second number be represented as q
where the value of q = 4
And , A = 57 x 4
where the blank spaces in the boxes are by distributive property and
A = 57 x 4
( 50 + 7 ) 4 = ( 50 x 4 ) + ( 7 x 4 )
On simplifying the equation , we get
A = 200 + 28
A = 228
Therefore , the value of A is 228
Hence , the expression is A = 228

This is a tricky question!
So we can quickly find the area of the whole circle through πr². That would be around 144π (remember, we are solving in terms of π, so we dont use 3.14)
Then, the circles. Through πr², we can find that the area of one circle is 9π. And since there are two circles, we can add these together to become 18π.
Now we subtract 144π from 18π to find the shaded area. 126π, and since we are doing this in the terms of π, we don't need to include that.
The price of Stock A at 9 A.M. was $12.95 Since then, the price has been increasing at the rate of $0.12 each hour. At noon the price of Stock B was $13.70. It begins to decrease at the rate of $0.13 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answer:
The prices of the two stocks will be the same in 1.56 hours.
Step-by-step explanation:
The price of Stock A at 9 A.M. was $12.95 Since then, the price has been increasing at the rate of $0.12 each hour.
This means that after x hours, the value of Stock A is:
[tex]S_{A}(x) = 12.95 + 0.12x[/tex]
After noon:
Noon is 3 hours after 9 AM, so
[tex]S_{A}(3) = 12.95 + 0.12*3 = 13.31[/tex]
So in x hours after noon, the value is given by:
[tex]S_{A}(x) = 13.31 + 0.12x[/tex]
At noon the price of Stock B was $13.70. It begins to decrease at the rate of $0.13 each hour.
This means that after x hours, the value of Stock B is:
[tex]S_{B}(x) = 13.70 - 0.13x[/tex]
In how many hours will the prices of the two stocks be the same?
This is x for which:
[tex]S_{A}(x) = S_{B}(x)[/tex]
[tex]13.31 + 0.12x = 13.70 - 0.13x[/tex]
[tex]0.25x = 0.39[/tex]
[tex]x = \frac{0.39}{0.25}[/tex]
[tex]x = 1.56[/tex]
The prices of the two stocks will be the same in 1.56 hours.

Answer:
(2/3)(e^t +1)^(3/2)
Step-by-step explanation:
Use the substitution ...
u = e^t +1
Then du = e^t and you are finding the integral of ...
∫u^(1/2)·du
which you know by the power rule is ...
(2/3)u^(3/2) = (2/3)(e^t +1)^(3/2)
Sydney simplifies the expression 2csc(-y) with the work below. What did she do wrong? 2csc(x+y)= 2/sin(x-y)
=2/cos x cos(-y)+sin xsin(-y)
=2/cos x cos y - sin xsin y
=2/cos( x +y)
= 2 sec (x + y)
Answer:
We know that:
csc(x) = 1/sin(x)
Now we want to work with:
2csc(x+y)
The first step is:
2csc(x+y)= 2/sin(x-y)
This is correct so far.
Now we need to use the relation:
sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)
Then:
sin(x - y) = sin(x)*cos(-y) + sin(-y)*cos(x)
sin(x) is an odd function, then: sin(-y) = -sin(y)
and cos(x) is an even function, then:
cos(-y) = cos(y)
Then we get:
sin(x - y) = sin(x)*cos(y) - sin(y)*cos(x)
then:
2/sin(x-y) = 2/(sin(x)*cos(y) - sin(y)*cos(x))
Now let's look at what she did:
2/sin(x-y) = 2/(cos x cos(-y)+sin xsin(-y))
Here is her error, she replaced:
sin(x - y) by cos x cos(-y)+sin(x)sin(-y)
This relation is for the cosine function, not the sine one, so here is her mistake.
