Factor the polynomial:
462 + 15b - 4
Answers
Answer:
15([tex]\frac{458}{15}[/tex]+b) or
15(b+[tex]\frac{458}{15}[/tex])
Step-by-step explanation:
First we can subtract the 4.
458 + 15b
Now we need to find the GCF, but they do not share any kinds of factors together. This might look ugly, but it is what it is. We factor out 15 to get b by itself.
15([tex]\frac{458}{15}[/tex]+b) or
15(b+[tex]\frac{458}{15}[/tex])

Heather's school is selling tickets to the annual dance competition. On the first day of ticket sales the school sold 6 adult tickets and 7 student tickets for a total of $120. The school took in $168 on the second day by selling 12 adult tickets and 2 student tickets. Find the price of an adult ticket and the price of a student ticket.
Answers
Answer:
Price of adult ticket = x = $13
Price of student ticket = y = $6
Step-by-step explanation:
Let Price of adult ticket = x
Price of student ticket = y
Now, making equations:
On the first day of ticket sales the school sold 6 adult tickets and 7 student tickets for a total of $120. The equation will be:
[tex]6x+7y=120[/tex]
The school took in $168 on the second day by selling 12 adult tickets and 2 student tickets. The equation will be:
[tex]12x+2y=168[/tex]
Now, solving the equations simultaneously to find values of x and y.
Let:
[tex]6x+7y=120--eq(1)\\12x+2y=168--eq(2)[/tex]
Multiply eq(1) by 12 and then subtract both equations
[tex]12x+14y=240\\12x+2y=168\\-\:\:\:-\:\:\:\:\:\:\:\:\:-\\--------\\12y=72\\y=\frac{72}{12}\\y=6[/tex]
So, we get value of y: y=6
Now, Put value of y in equation 1 to find value of x
[tex]12x+2y=168\\Put\:y=6\\12x+2(6)=168\\12x+12=168\\12x=168-12\\12x=156\\x=\frac{156}{12}\\x=13[/tex]
So, we get value of x: x=13
The answer would be:
Price of adult ticket = x = $13
Price of student ticket = y = $6

Given :
Actual length of the bolt is 2.5 inches.
Measured length of the bolt is 2.6 inches.
To Find :
The percent error of the bolt.
Solution :
We know, percentage error is given by :
[tex]\delta =| \dfrac{Actual\ Value - Expected\ Value}{Expected\ Value}|\times 100\\\\\delta =| \dfrac{2.6-2.5}{2.5}|\times 100\\\\\delta = 4 \%[/tex]
Therefore, the percentage error in the bolt is 4% .

The y-intercept of the parent quartic function, f(x) = x^4
transformation?
Is translated 3 units to the right and 1 unit down. Which equation represents this
OA. g(t) = (1 + 1)4 + 3
OB. g(t) = (1 - 1)4 + 3
Oc g(1) = (1 – 3)4 – 1
OD. g(x) = (x + 3)4 - 1
Answers
The equation which represents the transformation of the y-intercept of the parent quartic function,[tex]f(x) = x^4[/tex] is given by [tex]g(x)=(x-3)^4-1[/tex] .
What is transformation ?Transformation is the act or process of changing completely. In this also the graph changes or transform.
We have,
Parent Quadratic equation [tex]f(x)=x^4[/tex]
And
It translated [tex]3[/tex] units to the right and [tex]1[/tex] unit down.
And the parent quadratic function is in the form of [tex]f(x) = a(x-h)^4 + k.[/tex]
Here,
"h" tells if the vertex of the parabola is going left or right.
"k" determines if the vertex of the parabola is going up or down.
So, According to the question;
We have,
[tex](a)[/tex] [tex]3[/tex] units to the right
[tex](b)[/tex] [tex]1[/tex] unit down
So,
Equation would be [tex]g(x)=(x-3)^4-1[/tex] means that you have moved the vertex of the parabola [tex]3[/tex] units to the right and [tex]1[/tex] units down.
(Always remember if moving right means [tex](x-3)[/tex] sign would be minus because in parent quadratic function is in the form of [tex]f(x) = a(x-h)^4 + k[/tex] we have minus sign.)
Hence, we can say that the equation which represents the transformation of the y-intercept of the parent quartic function,[tex]f(x) = x^4[/tex] is given by [tex]g(x)=(x-3)^4-1[/tex] .
