Answer:
D
Step-by-step explanation:
You have to multiply the functions
so (x+4)(3x^2-7)
Use the FOIL method to multiply them
3x^3+12x-7x-28 which is d
-2x^3+5x^2-3x-12 for x=2

Lin's bike travels 100 meters when her wheels rotate 55 times. What is the circumference of her wheels? Round your answer to the nearest hundredth.
Thank You!!!
Answer:
Using formula to calculate the circumference of wheel:
where
D is the distance bike travel
n is the number of times rotation
C is the circumference of the wheel
As per the statement:
Lin’s bike travels 100 meters when her wheels rotate 55 times.
here, n = 55 rotation and D = 100 meter.
then by definition:
meter
Therefore, the circumference of her wheel is, 1 9/11

HELP!!! IM CONFUSED
Answer:
2/3Step-by-step explanation:
If we want to find the slope, the most easiest way to find the slope is to use 'Rise/Run'. Two points are given, lets use those points and find the slope.
=> We see that the rise is 2. So 2 will be our numerator,
=> We can also see that the run is 3. So 3 will be our denominator.
What do we get?
We get 2/3 as our slope. Therefore, B is our answer. Hoped I helped.

Sully built a shelf 8 5/8 inches wide for his DVD collection. If each DVD is 3/8 inches
wide, how many can he fit on the new shelf?
Answer:
23
Step-by-step explanation:
8 5/8 = 69/8
Each DVD is 3/8 inches
Ignore the denominators
We have 69 and 3
69 is 23 times bigger than 3, so 23 DVD's can fit
y = -2x + 1 4x + y = 9
9514 1404 393
Answer:
(4, -7)
Step-by-step explanation:
Maybe you want the solution to this system of equations.
About the easiest way to obtain it is to use a graphing calculator.
(x, y) = (4, -7)
_____
Additional comment
Since one of the equations gives an expression for y, it is a simple matter to substitute that for y in the other equation.
4x +(-2x +1) = 9
2x = 8 . . . . . . . . . . subtract 1 and simplify
x = 4
y = -2(4) +1 = -7 . . . use the first equation to find y

Which of the following equations has one real solution?
2x2+x+3=0
x2+5x−3=0
x2−5x+4=0
4x2−12x+9=0
Answer:
4x2−12x+9=0
Step-by-step explanation:
The equation, 2x2+x+3=0, does not have a solution
The equation, x2+5x−3=0, equals -5/2+1/2√37 and -5/2+-1/2√37
The equation, x2−5x+4=0, equal 1 and 4
The equation, 4x2−12x+9=0, equals only 3/2

Answer:
x^2 + 7x- 3/x - 3/x^2 -16
Step-by-step explanation:
Key: ( ^ ) means exponent
= x^2 + 2x- 3/x -2x^2 + 5x- 3/x^2 -16
= x^2 - 2x^2 + 2x+5x - 3/x- 3/x^2 -16
= x^2 - 2x^2 = -x^2
= -x^2 + 2x + 5x- 3/x- 3/x^2-16
As you see you add 2x and the 5x and got 7x
= Answer : x^2 + 7x- 3/x - 3/x^2 -16

determine if the lines are parallel, perpendicular, or neither. x - y = 4 and x + y = 9
Answer:
Perpendicular
Step-by-step explanation:
What I would do first is to rearrange these equations into the equation of a line formula: [tex]y=mx+c[/tex]
To do so, we isolate y:
x - y = 4 -> -y = -x+4 -> (multiply both sides by -1) y=x-4
x+y=9 -> y=-x+9
We know that in the formula y=mx + c, m stands for gradient of a line (The degree of steepness of the line), and we know that if there is no number before x it means that it is 1 or -1 (depending on the sign before x).
so that on y=x-4 the gradient is 1 and on y=-x+9 the gradient is -1.
We now can check if its parallel, perpendicular or neither with these equations:
m1 · m2 = -1 for perpendicular, m1 = m2 for parallel,(where m = gradient)
we plug the values of the two gradients into the first equation
(m1 · m2 = -1) and it fits: 1 x -1 = -1
If we plug the same values into the second equation (m1 = m2), we can check that 1 ≠ -1
In conclusion, we can check that these lines are perpendicular to each other.

Answer:
3.5 ft
Step-by-step explanation:
[tex]1 \frac{3}{4} = \frac{7}{4} [/tex]
7/4 inch = ? feet
[tex] \frac{ \frac{1}{2} }{ \frac{7}{4} } = \frac{1}{x} \\ \\ \frac{4}{14} = \frac{1}{x} \\ x = \frac{7}{2} [/tex]
3.5 ft
Answer:
3.5 ft.
Step-by-step explanation:
The question describes a bookshelf with width given in inches and we have to find the actual width in feet.
That makes it
Conversion of lengths from inches to feets:The bookshelf drawn by Sarita is
[tex]1 \frac{3}{4} [/tex]
inches wide.
Converting a mixed fraction to its simplest formAny fraction with it's quotient greater than or equal to 1 can be expressed in the form of mixed fraction.
It combines a whole number and a fractional reminder. The whole number represents how many complete wholes you have.
So, to convert a mixed fraction to an improper fraction, following steps will be conducted:
STEP I
(multiply the whole number by the denominator)
In this case,
[tex] 1\frac{3}{4} [/tex]
Denominator = 4whole number = 1= 4 × 1
= 4
STEP II
(add the product to the numerator)
numerator = 3 product obtained din step 1 = 4= 3 + 4
= 7
STEP III
(place the numerator obtained in Step 3 over the denominator)
new numerator = 7 denominator = 4Which gives us the fraction:
[tex] \boxed{ \frac{7}{4} }[/tex]
So, the width of the bookshelf is 7/ 4 in.
Expressing it in feets:[tex] \mathsf{ \frac{1}{2} \: inches \: represent = 1 \: feet }[/tex]
[tex] \mathsf{ 1 \: inch \:will\: represent = 1 \times \: \frac{2}{1} feet }[/tex]
[tex] \mathsf{ \frac{7}{4} \: inches \:will\: represent = 2 \times \: \frac{7}{4} feet }[/tex]
[tex] \implies \mathsf{ \underline{\frac{7}{2} \: ft. }}[/tex]
[tex] \mathsf{or}[/tex]
[tex] \implies \: \mathsf{ \underline{3.5 \: ft.}}[/tex]
That makes it Option: D) 3.5 ft.

and the lines equation is y=2x-8
plz help this is past due
Answer:
-8
Step-by-step explanation:
if you sub in 8 as the value for y, you get

Which function has the greater rate of change? What is that value?
Answer:
To find the rate of change you use the formula, Y2-Y1/X2-X1.
Function A:
You can substitute in any two points. The points I will use are (0,0) and (1,1).
1-0/1-0
1/1
1
The rate of change for Function A is 1.
Function B:
The points I will use are (2,1) and (4,2).
2-1/4-2
1/2
The rate of change for Function B is 1/2.
Since 1 is larger than 1/2, Function A has a larger rate of change. The value is 1.
Hope this helps! :)
