elimination method steps
Answer:
Remarks:The method used in solving the example above is called the elimination method, because we eliminate one variable first, to get a linear equation in one variable. In the example above, we eliminated y. We could also have eliminated x. Try doing it that way. 2. You could also have used the substitution, or graphical method, to solve this problem. Try doing so, and see which method is more convenient.
steps of elimination method: Step 1:First multiply both the equations by some suitable non-zero constants to make the coefficients of one variable (either x or y) numerically equal. Step 2: Then add or subtract one equation from the other so that one variable gets eliminated. If you get an equation in one variable, go to Step 3. If in
Step 2:we obtain a true statement involving no variable, then the original equations has infinitely many solutions. If in Step 2, we obtain a false statement involving no variable, then the original pair of equations has no solution, i.e., it is inconsistent.
Step 3:Solve the equation in one variable (x or y) so obtained to get its value.
Step 4:Substitute this value of x (or y) either of the original equations to get the value of the other variable.

Answer:
85 Square Units
Step-by-step explanation:
We need to start by finding the area of the triangle:
(base*height)/2
[tex]\frac{17*10}{2} =85[/tex]
Then we find the area of the rectangle:
Height*Width= 170
Then we finally take the area of the rectangle (170) and subtract the area of the triangle (85) and we get the answer of 85.

Answer:
Straightforward: 70 + 48 or 72 + 46
With other ways: below ↓
Make a ratio and increase.
6:4
Find the least common multiples.
72:48
Next, take these 2 out of ratio form and add them together.
72
+48
120
Since the closest we get is 120...
We must change the LCM'S to get the true number. Either way, it will work if you reduce 48 by 2, or 72 by 2. Same answer.
[tex]120-2=118dollars\\72 - 2\\48 - 2[/tex]
Therefore,
Our problem answer can be seen as the original ratio, but modified, 72:48 or simply 70 + 48. For the ratio to be correct, you would have to factorize the least common multiples and re-add. I would not recommend this.
What’s the midpoint of a line segment joining the points (5,-4) and(-13,12)?
Great question! A midpoint is exactly what it sounds like; the point in the middle of two objects (in this case it's the middle of these two coordinates). Another way to think of the middle of something in math is by using the average. To find the midpoint of two points, we just find the average of the x-values and the average of the y-values:
((x1 + x2)/2 , (y1 + y2)/2)
((5 + -13) / 2 , (-4 + 12) / 2)
( -8 / 2 , 8 / 2)
(-4 , 4)

Answer:
The next 3 steps are:
#1: [tex]\sqrt{ (x+2)^{2}} =\sqrt{10}[/tex] -- Using the square root method, we're going to find the square root of both sides.
#2: [tex]x+2 = \frac{+}{} \sqrt{ 10 }[/tex] -- When finding the square root of 10 it has to be + and minus.
#3: [tex]x + 2 = \frac{+}{}\sqrt{10} \\ -2 \ \ \ \ \ \ \ -2\\[/tex] -- Subtract 2 on both sides
#4 (solution): [tex]x = -2 \frac{+}{} \sqrt{10}[/tex]

You and a friend are playing a game by tossing two coins. If both coins land on heads,
you win. If both land on tails, your friend wins. Otherwise, nobody wins. The table shows
the possible outcomes.

Both have 2 heads and 2 tails so that's 4 and it's a fair game and b is wrong and you will eliminate c.
The game is fair because there is an equal chance of winning an losing the game.
What is probability?Probability is simply how likely something is to happen.
Probability formula[tex]P(E )=\frac{Number\ of \ favorable\ outcomes }{Total\ number \ of outcomes}[/tex]
Where,
P(E) is the probability of an event.
What is the fair game?A fair game is the game in which there is an equal chance of wining or losing.
According to the given question.
Two coins are tossed.
[tex]\implies sample\ space= \{ HH, HT, TH, TT\}[/tex]
[tex]\implies total\ number \ of outcomes = 4[/tex]
Therefore,
The probability that you win is given by
[tex]P(E_{1} )=\frac{Number\ of \ favorable\ outcomes }{Total\ number \ of outcomes}[/tex]
[tex]\implies P(E_{1} )= \frac{1}{4}[/tex] (getting HH is a favorable outcome)
[tex]\implies probability\ of\ losing\ the\ game = 1-\frac{1}{4} =\frac{3}{4}[/tex]
And, the probability that your friend wins the game is given by
[tex]P(E_{2}) = \frac{Total\ number\ of\ favorable\ outcomes\ }{Total\ number\ of\ outcomes}[/tex]
[tex]\implies P(E_{2} )=\frac{1}{4}[/tex] (getting TT is the favorable outcome)
[tex]\implies probability\ of\ losing\ the\ game = 1-\frac{1}{4} =\frac{3}{4}[/tex]
Hence, the game is fair because there is an equal chance of winning an losing the game.

Consider the function. Which conclusions can be drawn about f–1(x)? Select two options. F–1(x) has a slope of. F–1(x) has a restricted domain. F–1(x) has a y-intercept of (0, –36). F–1(x) has an x-intercept of (–36, 0). F–1(x) has a range of all real numbers.
The required function is [tex]y = -\frac{3}{2} x -36[/tex] having domain and range as R and y-intercept is -36.
Given function
y=f(x) = [tex]-\frac{2}{3} x -24[/tex]
What is an inverse function?An inverse function is a function that returns the original value for which a function has given the output. If f(x) is a function that gives output y, then the inverse function of y, i.e. f-1(y) will return the value x.
In order to get inverse function [tex]f^-1x[/tex] let us arrange the given function
[tex]y+24 = -\frac{2}{3} x[/tex]
[tex]x = -\frac{3}{2} y-36[/tex]
Now, replace x with y and vice versa.
[tex]y = -\frac{3}{2} x -36[/tex]........(1)
or, [tex]f^-1x = -\frac{3}{2} x -36[/tex]
(1) will be the inverse function of the given function.
For x-intercept put y = 0 and for y-intercept put x=0 in eq(1)
x-intercept = -24
y-intercept = -36
The domain and range of f⁻¹x = set of all real numbers since f⁻¹x is a straight line equation, domain, and range of which is set of all real numbers.
Therefore, the required function is [tex]y = -\frac{3}{2} x -36[/tex] having domain and range as R and y-intercept is -36.
