If x+3 is a factor of x^3-x^2-10x+A. What is the value of A?
Answer:
[tex]A = 6[/tex].
Step-by-step explanation:
Let [tex]a[/tex] denote a constant (a number, rather than a variable like [tex]x[/tex].)
Let [tex]f(x)[/tex] denote an expression about [tex]x[/tex] (for example,
By the factor theorem, if [tex](x - a)[/tex] is a factor of [tex]f(x)[/tex], then [tex]f(a) = 0[/tex]. In other words, if all mentions of [tex]x[/tex] in the expression [tex]f(x)\![/tex] are replaced with [tex]a[/tex], then the expression should evaluate to zero.
[tex](x + 3)[/tex] is equivalent to [tex](x - (-3))[/tex]. That is: [tex]a = -3[/tex].
Replace all mentions of [tex]x[/tex] in [tex]x^3 - x^2 - 10\, x + A[/tex] by [tex](-3)[/tex] to get:
[tex](-3)^3 - (-3)^2 - 10\times (-3) + A[/tex].
That should evaluate to zero. Therefore: [tex]-27 - 9 + 30 + A = 0[/tex]. Solve for [tex]A[/tex] to get [tex]A = 6[/tex].

Nick is taking his written drivers test. As he answers each question, the progress bar at the bottom of the screen shows how many questions he has completed. He just completed question 16, and the progress bar shows he is 20% complete. How many total questions are there
Answer: 80
Step-by-step explanation: If he is 20% complete, then 20 x 5 is 100. So if we want to get 100%, then we have the multiply. Now he did 16 questions, so we have to multiply 16 five times. 16 x 5

In the middle school coding club, 30% of the members are in 6th grade. If there are 12 sixth graders in the club, how many total members are there?
Answer:
40 members
Step-by-step explanation:
Let the total members = x
Given the following data;
Number of sixth graders = 12 members
The mathematical expression is;
[tex] \frac {30}{100} * x = 12[/tex]
[tex] 0.3x = 12[/tex]
[tex] x = \frac {12}{0.3} [/tex]
x = 40
Therefore, the total members in the middle school coding club is 40 members.
Write Absolute value equation that has the given solutions 4 and 11
We want to find an absolute value equation such that its solutions are 4 and 11.
We will get: |x - 7.5| = 3.5
Let's see how we can get that.
We should start by the general absolute value equation:
|x - a| = b
This can be decomposed into two equations:
x - a = b
x - a = -b
Both of these must be true, one for each of the given solutions of the equation, now we need to replace these solutions. Let's use the largest solution in the equation where b is positive.
11 -a = b
4 - a = -b
Now we have a system of equations, to solve it we can see that we have the same variable isolated in the two equations, then we can rewrite:
11 - a = b
-(4 - a) = b
then:
11 - a = b = -(4 - a)
11 - a = -4 + a
11 + 4 = a + a
15 = 2*a
15/2 = a = 7.5
Then we can use:
11 - a = b
11 - 7.5 = b = 3.5
Now we know the values of a and b, we just need to replace them in the general equation to get:
|x - 7.5| = 3.5
This is the absolute value equation we were searching.

If a gallon of gasoline costs $3.499 and increases $0.09, what is the price of gasoline after the increase? please please please help!! thanks!!
Answer: $3.58
Step-by-step explanation:
Since the cost is increasing, you need to add the two values together.
$3.49 + $0.09 = $3.58
The price of gasoline after the increase is $3.58.

The perimeter of a rectangular pool is 56 meters. If the length of the pool is 16 meters, then find its width.Here the perimeter and the length of the rectangular pool are given. We have to find the width of the pool.
Write and solve an equation to determine its width?
ALSO THERE NO M JUST 16 NO 16M
Answer:
Width = 12 m
Step-by-step explanation:
Width = w
Perimeter = 56 m
2*length + 2*width = 56
2* 16 + 2w = 56
32 + 2w = 56
2w = 56 - 32
2w = 24
w = 24/2
w = 12 m
Width = 12 m

What is an equation of the line that passes through the point (1,6) and is perpendicular to the line x+3y=27
Step-by-step explanation:
to get the original slope, we need to bring the line equation to
y = ...
and the slope is the factor of x.
x + 3y = 27
3y = -x + 27
y = -1/3 x + 9
so, the original slope is -1/3.
the perpendicular slope turns this upside-down and flips the sign : 3/1 = 3.
as the slope is the ratio "y coordinate change / x coordinate change".
we can use the point-slope form for the new line equation :
y - y1 = m(x - x1)
with m being the slope, and (x1, y1) being a point on the line.
so,
y - 6 = 3(x - 1)
simplified that is
y - 6 = 3x - 3
y = 3x + 3
that is then the slope-intercept form (+3 being the interception point on the y-axis).
Answer:
y = 3x + 3

Step-by-step explanation:
3. since the scale is every 1cm is 14 miles than to find 56 miles on a map you should divide 56/14 which would equal 4cm.
4. since the scale is every 1 inch is 6 feet and you have to find how long a motorcycle is if it was 2 in on a diagram, then you should multiple 6 by 2 which would equal 12 feet

How can you find sums and differences of rational expressions? Explain
Answer: A rational expression is a ratio of two polynomials.
Step-by-step explanation: To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator. When the denominators are not the same, we must manipulate them so that they become the same. In other words, we must find a common denominator.
