Use the factor theorem to determine if the given binomial is a factor of f (x).
oee [108]

Answer:

<em>The binomial is a factor</em>

Step-by-step explanation:

In order to show that x+3 is a factor of the polynomial, then;

f(a) = 0

Get a by equating x+3 to zero

x+3 = 0

x = -3

Get f(-3)

f(-3) =  (-3)^4 + 8(-3)^3 + 11(-3)^2 -11(-3) + 3

f(-3) = 81 - 216 + 99 + 33 + 3

f(-3) = 216-216

f(-3)  = 0

<em>Since the remainder of the polynomial when divided by x+3 is zero, this shows that x+3 is a factor of the given polynomial</em>

write the slope-intercept form of the line that passes through the point (1,0) and is parallel to x-y=7. type your answer in the
dlinn [17]
We know that

<span>a) the slope-intercept form of the line---------------> y=mx+b
b) </span><span>if two lines are parallel both have the same slope
</span>then
<span>passes through the point (1,0) and is parallel to x-y=7

Step 1
Find the slope
</span>x-y=7------------> y=x-7------------> m=1

Step 2
Find the slope-intercept form of the line---> y=mx+b
point (1,0)  m=1
0=(1)*(1)+b------> b=-1
y=(1)*x-1--------> y=x-1

the answer is 
y=x-1

using a graph tool
see the attached figure

Which of the following is the function T(a) if T^-1(a)=11a-2
SpyIntel [72]

Answer:

T(a) =(a+2)/11

Step-by-step explanation:

The inverse of the inverse is the function

To find the inverse let T^-1(a) be y

y = 11a -2

Exchange y and a

a = 11y -2

Solve for y

Add 2 to each side

a+2 = 11y -2 +2

a+2 =11y

Divide each side by 11

(a+2)/11 =y

T(a) =(a+2)/11

erma4kov [3.2K]
At the Children's Theater, each row can seat 25 people. So, if there are 63 rows, there would be the total of 1,575 people.

At the Bartell Theater, which can seat 2,048 people, there are 64 rows. Each row can seat 32 people.

So, 7 more people are seated in each row at the Bartell Theater than at the Children's Theater.
