Answer:
3x+1=2x+40
We move all terms to the left:
3x+1-(2x+40)=0
We get rid of parentheses
3x-2x-40+1=0
We add all the numbers together, and all the variables
x-39=0
We move all terms containing x to the left, all other terms to the right
x=39
Step-by-step explanation:
Answer:
x = 48
Step-by-step explanation:
Original equation:
1/3x + 1/2x = 40
Add 1/3x to 1/2x
5/6x
Equation Now:
5/6x = 40
Divide both sides by 5/6
x = 48

factorise a³ - b³ + 4a-4b
Answer:
[tex]a^3-b^3+4a-4b:\:\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]
Step-by-step explanation:
Given the expression
[tex]a^3-b^3+4a-4b[/tex]
solving the expression
[tex]a^3-b^3+4a-4b[/tex]
as
[tex]a^3-b^3[/tex][tex]\mathrm{Apply\:Difference\:of\:Cubes\:Formula:\:}x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)[/tex]
[tex]a^3-b^3=\left(a-b\right)\left(a^2+ab+b^2\right)[/tex]
also
[tex]4a-4b[/tex][tex]\mathrm{Factor\:out\:common\:term\:}4[/tex]
[tex]=4\left(a-b\right)[/tex]
so the expression becomes
[tex]=\left(a-b\right)\left(a^2+ab+b^2\right)+4\left(a-b\right)[/tex]
[tex]\mathrm{Factor\:out\:common\:term\:}\left(a-b\right)[/tex]
[tex]=\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]
Therefore,
[tex]a^3-b^3+4a-4b:\:\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]

A 9 kg log is being dragged along flat ground by a 120 N force at an angle of 45°. If
the log accelerates at a rate of 0.78 m/s2, what is the normal force acting on the log?
9514 1404 393
Answer:
3.347 N
Step-by-step explanation:
The vertical component of the dragging force is (120 N)/√2, so the net downward force is the difference between that due to gravity and the upward component of the dragging force.
(9.8 m/s²)(9 kg) -(120 N)/√2 = 3.347 N
The normal force acting on the log is 3.347 N.
g(x) = f(x - 4) + 5

x = 10
Step-by-step explanation:
An isosceles triangle has two sides of equal length. In this triangle, there is a little line in the middle of two out of the three sides of the triangle. This line tells us that those two sides are equal. We know that the value of these sides are 4x - 8 and 2x + 12. So, to find the value of x, we can set the equations equal to each other and solve for x:
4x - 8 = 2x + 12
Subtract 2x from both sides to isolate x:
2x - 8 = 12
Add 8 to both sides:
2x = 20
Divide both sides of the equation by 2 to find the value of x:
x = 10

A rectangle has a perimeter of 42 m and a length of 15 m. What is
the width of this rectangle in metres? (Perimeter = 2(length + width))
Answer:
6 meters
Step-by-step explanation:
the perimeter is all of the sides added up so to find the added width you subtract the added length which is 30 so 42-30 is 12 so the added width is 12. To find one width you divide 12 by 2 so one width of the rectangle would be 6 meters
what is the measure of the angles in the triangle shown below.
Answer:
x = 35 degrees
Step-by-step explanation:
All angles in a triangle add up to 180 degrees.
Therefore, 48 + 97 + x = 180
Solve for x.
Thus, x = 180 - 48 - 97.
x = 35 degrees
How many solutions would a quadratic equation have if the discriminant is 12? brainliest to the first correct answer
Answer:
two
Step-by-step explanation:
If the discriminant of a quadratic equation is 12 then it has two distinct real roots. That 12 is not a perfect square, so if the coefficients of the quadratic are integers or otherwise rational, then the roots are both irrational.
Answer:
two
If the discriminant of a quadratic equation is 12 , then it has two distinct real roots. Note that 12 is not a perfect square, so if the coefficients of the quadratic are integers or otherwise rational, then the roots are both irrational.

In one hour, Jason can install at least 6 windows
but no more than 8 windows. Which of the
following could be a possible amount of time, in
hours, that Jason takes to install 100 windows in
a home?
th
A) 12
B) 16
C) 17
D) 18
Answer:
B.
Step-by-step explanation:
Possible amount of hours to install 100 windows = 16 hrs.
The correct option is (B).
What is an Inequality?In Algebra, inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol. The expressions on both sides of an inequality sign are not equal. It means that the expression on the left-hand side should be greater than or less than the expression on the right-hand side or vice versa. If the relationship between two algebraic expressions is defined using the inequality symbols, then it is called literal inequalities.
Given,
Number of windows Jason can install in 1 hour = 6 ≤ x ≥ 8
Time taken in installing 1 window = 1/6 ≤ 1/x ≥ 1/8
Time taken in installing 100 windows = 1/6 × 100 ≤ 1/x × 100 ≥ 1/8 × 100
Time taken in installing 100 windows = 12.5 ≤ t ≥ 16.67
Then the possible amount of time taken will be in range of 12.5 to 16.67 hrs.
Hence, Jason will take around 16 hrs. to install 100 windows.

Use a graphing calculator to graph f(x) = x+cos(kx). Use calculus to determine which values of k lead to a function with no local maxima or minima. What conclusions can be drawn?
Answer:
Below, you can see the graph of the function:
f(x) = x + cos(k*x)
for different values of k, as follows:
red: k = 1
green: k = 2
orange: k = 0.
Now let's find the values of k such that our function does not have local maxima nor local minima.
First, remember that for a given function f(x), the local maxima or minima points are related to the zeros of the first derivate of f(x).
This means that if:
f'(x0) = 0.
Then x0 is a maxima, minima or an inflection point.
Then if a function is such that the f'(x) ≠ 0 , ∀x, then this function will not have local maxima nor minima.
Now we have:
f(x) = x + cos(k*x)
then:
f'(x) = 1 - k*sin(k*x)
This function will be zero when:
1 = k*sin(k*x)
1/k = sin(k*x)
now, remember that -1 ≤ sin(θ) ≤ 1
then if 1/k is smaller than -1, or larger than 1, we will not have zeros.
And this will happen if -1 < k < 1.
Find the slope of the line that passes through (10, 9) and (1, 1).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
The slope of the line that passes through (10, 9) and (1, 1) will be:
[tex]m=\frac{8}{9}[/tex]Step-by-step explanation:
Given the points
(10, 9)(1, 1)The slope between (10, 9) and (1, 1) is given by
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(10,\:9\right),\:\left(x_2,\:y_2\right)=\left(1,\:1\right)[/tex]

Find the slope of the line that passes through (-3, 2) and (6, 2).
Answer:
slope = 0
Step-by-step explanation:
(-3, 2) and (6, 2)
slope = (y1 - y2)/(x1 - x2)
remember, either x or y can be used but you have to be consistent
slope = (2-2)/(-3-6)
slope = 0/(-9)
slope = 0
Answer: no slope or 0
Step-by-step explanation:
The y-coordinates are the same for both points but the x coordinates are different. This signals a no-slope line, or a line where the slope is 0. Even if we apply the formula, which is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], it still ends up with 0.
