Step-by-step explanation:
Konichiwa~! My name is Zalgo and I am here to help you out on this great day. Hmm, how do you define slope... Well, the slope or "gradient" of a line is a number that describes both the steepness and direction of the line itself. Now, slope is "a surface of which one end or side is at a higher level than another; a rising or falling surface".
I hope that this helps you! :P

A triangular playground has angles with measures in the ratio 8 : 6 : 4. What is the measure of the smallest angle?
Answer:
20°
Step-by-step explanation:
One way of doing this is to find the constant of proportionality, k:
8k + 6k + 4k = 90° Then 18k = 90°, and k turns out to be 90/18, or 5.
Then the angles are 8(5), 6(5) and 4(5). The smallest of these angles is thus 20°
let's recall that the sum of all interior angles in a triangle is 180°.
we know the angles are in a 8:6:4 ratio, so we simply divide 180 by (8+6+4) and then distribute accordingly.
[tex]\bf 8:6:4\qquad \qquad \left( 8\cdot \cfrac{180}{8+6+4} \right) : \left( 6\cdot \cfrac{180}{8+6+4} \right) : \left( 4\cdot \cfrac{180}{8+6+4} \right) \\\\\\ (8\cdot 10):(6\cdot 10):(4\cdot 10)\implies 80~:~60~:~\stackrel{\textit{smallest}}{40}[/tex]
Felix wrote several equations and determined that only one of the equations has no solution. Which of these equations has no solution?
Answer:
3(x-2)+x=4x+6
Step-by-step explanation:
case 1) we have
3(x-2)+x=4x-6
Solve for x
3x-6+x=4x-6
4x-6=4x-6
0=0 ----> is true for any value of x
therefore
The equation has infinite solutions
case 2) we have
3(x-2)+x=2x-6
3x-6+x=2x-6
4x-2x=-6+6
2x=0
x=0
case 3) we have
3(x-2)+x=3x-3
3x-6+x=3x-3
4x-3x=-3+6
x=3
case 4) we have
3(x-2)+x=4x+6
3x-6+x=4x+6
4x-4x=6+6
0=12 ------> is not true
therefore
The equation has no solution
Answer:
3(x-2)+x=4x+6Step-by-step explanation:
The first equation is the one that doesn't have solution. Let's demonstrate this:
[tex]3(x-2)+x=4x+6\\3x-6+x=4x+6\\4x-6=4x+6\\4x-4x=6+6\\0=12[/tex]
As you can observe, the equation doesn't have any solutions, because it result in a false statement.
If we solve the other equations, we would have:
[tex]3(x-2)+x=2x-6\\3x-6+x=2x-6\\4x-6=2x-6\\4x-2x=-6+6\\2x=0\\x=0[/tex]
[tex]3(x-2)+x=3x-3\\3x-6+x=3x-3\\4x-3x=-3+6\\x=3[/tex]
[tex]3(x-2)+x=4x-6\\3x-6+x=4x-6\\4x-6=4x+6\\6=6[/tex]
The last equation has infinite solutions.
Therefore, the only one that doesn't have any solutions is
3(x-2)+x=4x+6If f(x) = 3x^2 and g(x) = 4x^3 + 1, what is the degree of (fg)(x)?
i think this question already been solved:
https://brainly.com/question/4342896
Answer:
degree 5
Step-by-step explanation:
(fg)(x) = f(x) × g(x)
f(x) × g(x) = 3x²(4x³ + 1) = 12[tex]x^{5}[/tex] + 3x²
The degree of the polynomial is determined by the value of the largest exponent, that is
12[tex]x^{5}[/tex] ← largest exponent of 5
Hence (fg)(x) is of degree 5
If you double a number and add 1 you get 11 what is the number
Answer:
Should be 5, hopes this helps
Step-by-step explanation:
That's it.
Final answer:
To find the original number, we use the equation 2x + 1 = 11; solving for x gives us the number 5.
Explanation:
To find the number that when doubled and added to 1 gives 11, we can set up a simple algebraic equation to solve for the unknown number. Let's call the unknown number x. According to the problem, if we double the number (2x) and then add 1, the result is 11. So, our equation is 2x + 1 = 11.
Next, we can solve for x by subtracting 1 from both sides of the equation, giving us 2x = 10. Finally, we divide both sides by 2 to isolate x, resulting in x = 5. Thus, the number we're looking for is 5.

Rationalize the denominator- 12x/√x-10
ANSWER
[tex]\frac{ - 12x \sqrt{x} - 120x}{ x - 100} [/tex]
EXPLANATION
The given function is
[tex] \frac{ - 12x}{ \sqrt{x} - 10 } [/tex]
In the denominator we have
[tex] \sqrt{x} - 10[/tex]
The conjugate of this surd is
[tex] \sqrt{x} + 10[/tex]
To rationalize this function, we multiply both the numerator and the denominator by the conjugate surd.
[tex]\frac{ - 12x (\sqrt{x} + 10)}{ (\sqrt{x} - 10)(\sqrt{x} + 1)} [/tex]
We apply the identity
[tex] (a + b)(a - b) = {a}^{2} - {b}^{2}[/tex]
in the denominator.
This implies that,
[tex]\frac{ - 12x (\sqrt{x} + 10)}{ (\sqrt{x})^{2} - {10}^{2} } [/tex]
[tex]\frac{ - 12x \sqrt{x} - 120x}{ x - 100} [/tex]
What is the solution to the following equation?
x2 + 3x + 4 = 0
Answer:
No real solutions
Step-by-step explanation:
Using the quadratic formula, you will end up with a square root of a negative number in the numerator. Hence there is no real solution.
see attached.
The solution to the equation x^2 + 3x + 4 = 0 can't be computed using real numbers, because the formula we use (the quadratic formula) results in the square root of a negative number. Therefore, the solutions will be in the form of complex numbers.
Explanation:The subject question falls under Mathematics, specifically algebra. The equation given is a standard form of a quadratic equation. The general form of a quadratic equation is ax2 + bx + c = 0.
To find the solution for the equation x2 + 3x + 4 = 0, we usually use the quadratic formula x = [-b ± sqrt(b2 - 4ac)] / 2a. Applying this formula, we can put a = 1, b = 3 and c = 4. However, when we compute b2 - 4ac, which is 9 - 16, we receive a negative result (-7). This implies that the equation has no real solutions, because square roots of negative numbers are not real numbers, they are complex numbers.

How many solutions does the following system of equations have?
y=5/2x+2
2y= 5x +4
Answer:

Step-by-step explanation:
y=5/2x+2
2y= 5x +4
Multiply the first equation by 2
y = 5/2 x +2
2y = 5/2 *2 x +2 *2
2y = 5x +4

(2x-7)+(3x - 1)
Answer:
5x - 8
Step-by-step explanation:
(2x - 7) + (3x - 1)
We would first solve for whatever is in the parenthesis, but there is a variable with both expressions, so we need to remove it to simplify:
2x - 7 + 3x - 1
Now combine like terms and simplify:
2x + 3x - 7 - 1
So the answer is 5x - 8
Final answer:
To add the expressions (2x-7) and (3x - 1), simply combine the like terms, resulting in 5x - 8.
Explanation:
When you are tasked with adding the expressions (2x-7) and (3x - 1), you combine like terms. This means you add the coefficients of the same powers of x together and combine the constants. To demonstrate:
(2x-7) + (3x - 1) = (2x + 3x) + (-7 - 1)
You combine the x terms:
2x + 3x = 5x
And then combine the constants:
-7 - 1 = -8
Thus, the sum of the expressions is:
5x - 8

Answer:
-1/5x +1/2
ghiybifvcodtgy78
Answer:
b.[tex]y=-\frac{1}{5}x+\frac{1}{2}[/tex]
Step-by-step explanation:
We have to find the linear which has same slope as the slope represented by the table.
Slope formula :m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
By using the formula and substitute [tex]y_1=\frac{1}{5},y_2=\frac{7}{50},x_1=-\frac{1}{2},x_2=-\frac{1}{5}[/tex]
Slope=[tex]\frac{\frac{7}{50}-\frac{1}{5}}{-\frac{1}{5}+\frac{1}{2}}[/tex]
Slope=[tex]\frac{-\frac{3}{50}}{\frac{3}{10}}[/tex]
Slope=[tex]-\frac{3}{50}\times \frac{10}{3}[/tex]
Slope=[tex]-\frac{1}{5}[/tex]
a.[tex]y=-\frac{1}{2}x+\frac{1}{10}[/tex]
Compare with
[tex]y=mx+b[/tex]
we get m=[tex]-\frac{1}{2}[/tex]
Slope=[tex]-\frac{1}{2}[/tex]

Consider the given function.
pic below
Change f(x) to y , switch x and y , and solve for y.
The resulting function may be written as:[tex]f^{-1}x=\dfrac{\ln (x+4)}{2}[/tex]
Step-by-step explanation:We know that while finding the inverse of a function the following steps are to be followed:
We first put f(x)=yThen we interchange x and y in the expression.and then we finally solve for y.We are given a function f(x) by:
[tex]f(x)=e^{2x}-4[/tex]
Now, we put
[tex]f(x)=y[/tex]
i.e.
[tex]e^{2x}-4=y[/tex]
Now, we interchange x and y as follows:
[tex]e^{2y}-4=x[/tex]
and finally we solve for y
i.e.
[tex]e^{2y}=x+4[/tex]
Taking logarithmic function both the side of the equation we get:
[tex]2y=\ln (x+4)\\\\i.e.\\\\y=\dfrac{\ln (x+4)}{2}[/tex]
i.e.
[tex]f^{-1}x=\dfrac{\ln (x+4)}{2}[/tex]
Which linear inequality is represented by the graph?
Answer:
Step-by-step explanation:
In this question we will find the equation of the dotted line first.
Since this line passes through two pints (0, 2) and (-3, -7)
So slope of the line will be m = [tex]\frac{y-y'}{x-x'}[/tex]
= [tex]\frac{-7-2}{-3-0}[/tex]
= [tex]\frac{-9}{-3}[/tex]
= 3
y-intercept of the line is c = 2
Now we will put these values in the standard form of the equation
y = mx + c
y = 3x + 2
Now we will check the inequality shown by shaded region
we take a point from shaded region and plug in the value of x and y.
For point ( -2, 0) y = (-2)(2)+2
= -4 + 2 = -2 and 0>-2
So there should be the sign of greater than.
Therefore, inequality will be y > 3x + 2
Linear inequality represented by the graph is y > 3x +2 and this can be determine by using the slope intercept form.
Given :
Two points - (0 , 2) and (-3 , -7)
Slope of the line can be calculated as follows:
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-7-2}{-3-0}=3[/tex]
y intercept is 2.
Now we know that the slope intercept form is given by:
y = mx + c
y = 3x + 2 --- (1)
To check the inequality we take a point from the shaded region and plug in the value of x and y.
At Point (-3,0), equation (1) can be given by:
y = -9 + 2 = -7 < 0
Than inequality must be y > 3x + 2.

I'm taking this to mean
x/(x-2) + (x-1)/(x+1) = -1
Multiply through by (x - 2)*(x + 1) to get rid of the denominator on the left.
x(x + 1) + (x - 1)(x - 2) = -1 * (x - 2)(x + 1)
Remove the brackets on the left and right.
Be careful about the right side. Do it in two steps (or three)
x^2 + x + x^2 - 3x + 2 = - (x^2 - 2x + x - 2)
2x^2 - 2x + 2 = - (x^2 - x - 2)
2x^2 - 2x + 2 = - x^2 + x + 2
Bring the right side to the left
2x^2 - 2x + 2 + x^2 - x - 2 = 0
3x^2 - 3x = 0
Factor this
x*(3x - 3) =0
x = 0
3x - 3 = 0
Add 3 to both sides.
3x = 3
Divide by 3
x = 3/3
So either x = 0
or
x = 1
Just to confirm that that is correct, a graph is included which shows the x roots are 0 and 1

"The measures of two complementary angles are 6y + 3 and 4y - 13. Find the measures of the angles."
Answer:
The measures of two complementary angles are 63° , 27°
Step-by-step explanation:
The measures of two complementary angles are 6y + 3 and 4y - 13.
Sum of complementary angles = 90°
6y + 3 + 4y - 13 = 90°
10y - 10 = 90°
10y = 90 + 10 = 100
10 y = 100
y = 100/10 = 10
One angle = 6y + 3 = 6 * 10 + 3 = 60 + 3 = 63
other angle = 4y - 13 = 4 * 10 - 13 = 40 - 13 = 27
The angles are 63° , 27°
