Step-by-step explanation:
Your slope and your x and y intercept.
x + 2y =7
Divide through by 2, we have:
x/2 + 2y/2 = 7/2
x/2 + y = 7/2
y = 7/2 - x/2
In the form y = mx + c gives.
Where m is the slope.

○ x=80,y=38,z=63
○ x=85,y=38,z=63
○ x=80,y=48,z=63
Answer:
(b) x=80, y=38, z=63
Step-by-step explanation:
You want to know the values of x, y, and z, given they are angle measures in a diagram showing two triangles.
Linear pairThe angles that form a linear pair are supplementary:
x° +100° = 180°
x = 80 . . . . . . . . . divide by °, subtract 100
Angle sum theoremThe angle sum theorem tells you that the sum of angles in a triangle is 180°.
y° +62° +80° = 180°
y = 38 . . . . . . . . . . . . divide by °, subtract 142
In the other triangle, the same relation holds:
z° +100° +17° = 180°
z = 63 . . . . . . . . . . . . divide by °, subtract 117
The values of x, y, and z are ...
(x, y, z) = (80, 38, 63)

Find a with the given information.
m=-6/7 (-10,0) and (a,-6)
By using the equation to find the slope, we will see that the value of a is -3.
How to find the value of a?
Here we have two points that define a line.
Remember that a linear equation is of the form:
y = m*x + b
Where m is the slope.
And we know that if the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:
m = (y₂ - y₁)/(x₂ - x₁)
In this case, we know that the points are:
(-10, 0) and (a, -6), and the slope is m = -6/7, then we can write the equation:
-6/7 = (-6 - 0)/(a + 10) = -6/(a + 10)
The denominator should be the same in both sides, so we must have:
a + 10 = 7
a = 7 - 10 = -3
Then the two points are (-10, 0) and (-3, -6).

four coworkers are discussing their birthdates what is the probability of the months being different?
The probability of four coworkers having different birth months is 0.572 or 55/96
Given there are four coworkers and the condition is they should have different birth months.
As we know probability is the ratio of favorable out comes to the total number of outputs
Favorable outcomes are
For first person 12 months
For second person 11 months
For third person 10 months
For Fourth person 9 months
Total outcomes
For each and every person total outcomes are 12 months which add up to 12 x 12 x 12 x 12 = [tex]12^{4}[/tex]
Now probability will be

Opposite angles are equal.
x° angle is the opposite angle of the 90° angle.
Therefore, x°=90°.
28)
The 90° angle marked in the figure and the y° angles forms a linear pair.
Hence, both angles are supplementary. Supplementary angles sum upto 180°.
Therefore, we can write
[tex]\begin{gathered} y\degree+90\degree=180\degree \\ y\degree=180\degree-90\degree \\ y\degree=90\degree \end{gathered}[/tex]Therefore, y°=90°.

In the figure, let z°+46°=p°.
From figure, we can see that the p° angle is the opposite angle of y° angle.
Since opposite angles are equal, we can write
[tex]\begin{gathered} p\degree=y\degree \\ z\degree+46\degree=y\degree \end{gathered}[/tex]Since from part 28, y°=90°, we get
[tex]\begin{gathered} z\degree+46\degree=90\degree \\ z\degree=90\degree-46\degree \\ z\degree=44\degree \end{gathered}[/tex]Therefore, zh=44e.

what’s the inverse of Y equals X squared -10 X
The inverse of the function y equals x squared - 10x (y = x² - 10x) is 5 ±√(x + 25).
What is an inverse function?An inverse function simply refers to a type of function that is obtained by reversing the mathematical operation in a given function (f(x)).
First of all, we would translate the given word sentence into a function as follows:
y equals x squared - 10x ⇒ y = x² - 10x
In order to determine the inverse of this function f(x) = x² - 10x, we would interchange both the input value (x) and output value (y) as follows:
y = x² - 10x
x = y² - 10y
Next, we would add (half the coefficient of the y-term)² to both sides of the function as follows:
x + (-10/2)² = y² - 10y + (-10/2)²
x + 25 = y² - 10y + 25
x + 25 = (y - 5)²
±√(x + 25) = y - 5
Adding 5 to both sides of the function, we have:
5 ±√(x + 25) = y - 5 + 5
y = f⁻¹(x) = 5 ±√(x + 25)

The sentence becomes: "The sum of 4 times y and 5 is 2"
Replace "is" with the equals sign, "="
The sentence becomes: "The sum of 4 times y and 5 = 2"
Replace "times" with the multiply symbol, " * "
The sentence becomes: "The sum of 4 * y and 5 = 2"
Replace "the sum of ___ and ___" with " ___ + ___"
The sentence becomes: "4*y + 5 = 2".
the " * " isn't needed since 4y implies multiplication already, so you can optionally remove the *

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example,
Ram spends 36 Rs. for a dozen (12) bananas. 12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees. As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas. This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
In 177.4 gm of cereal contain 110 calories.
So, 1 gram cereal contain
= 177.4 / 110
= 1.6127
and, 246.5 gm will contain

Logan starts an IRA (Individual Retirement Account) at the age of 24 to save for retirement. He deposits $300 each month. Upon retirement at the age of 65. his
retirement savings is $1,510,293.29. Determine the amount of money Logan deposited over the length of the investment and how much he made in interest upon
retirement.
Total deposited = $147600
Interest earned = $1362693.29
Total no. of years for saving = 65-36-24 = 41
years saving no. of months = 41 x12

deposit for 1 month = $300 deposit for 492 month = 492 x $300= $147600
Total deposited = $147600
Total saving after retirement = $1,510,293.29 interest = total saving - total deposit= $1,510,293.29 - $147600

The slope of the line that passes through points (10,4) and (7, 3) is 1/3
Here we are dealing with a slope of a line where a slope of a line is the change in the y coordinate with regard to the change in the x coordinate. If P(x1,y1) and Q(x2,y2) are the two points on a straight line, at that point the slope formula is given by:
m = Change in y-coordinates/Change in x-coordinates
m = (y₂– y₁)/(x₂ – x₁)
Since we are given two points (10,4) and (7, 3), where x₁ and x₂ are 10, 7 whereas y₁ and y₂ are 4, 3
From the formula we get,
