Answer:
Complementary angles are two angles that add up to 90°.
For this, we need to know what the value of a is. If you have this value, plug it into this equation:
90 - 3a = measure of complementary angle
For example, if a = 20:
90 - 3(20) = x
90 - 60 = x
30° = measure of complementary angle

what is y - 1 = -5/2(x + 2) in pre-algebra standard form
Answer:
y=-5/2x-4
Step-by-step explanation:
y-l=-5/2(x+2)
Distribute the -5/2 to (x+2)
y-1=-5/2x-5
Add on on both sides of the equal sign
y=-5/2x-4
If this is not the right answer that you are looking for it is because I'm not in pre-algebra I just wanted to try to help.

using the slope formula find the slope of the line through the points (0,0) and (3,9) use pencil and paper explain how you can use mental math to find the slope of the line
Answer:
The answer is 3
Step-by-step explanation:
The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope of a line that passes through (x₁, y₁) and (x₂, y₂) is,
Slope = (y₂ - y₁)/(x₂ - x₁)
Since the given line is passing through (0,0) and (3,9).
Slope = (9 -0)/(3 - 0)
Slope = 3
Since the line is passing through the origin (0,0) so we can do it by mental math to divide y and x coordinate directly like 9/3 = 3.
Hence "The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3".

How many integers between 2020 and 2400 have four distinct digits arranged in increasing
order? (For example 2957 is one such integer)
(B) 10
(C) 15
(D) 21
e 28
Answer:
the answer is E
Step-by-step explanation:
We want to find how many integers are between 2020 and 2400 such that a criteria is meet, and the criteria is that the four digits are different and are arranged in increasing order.
We will see that there are 15 of these numbers between 2020 and 2400, so the correct option is C.
---------------------------
To count the number of digits that meet the given criteria, we first need to analyze how the criteria is.
If the numbers must be in increasing order, then the smallest number that can be in the hundreds place is 3 (the smaller integer larger than 2).
so we have:
23__
The number next to the 3 can be a 4, for example:
234_
And the final number can be any number larger than 4, so we have {5, 6, 7, 8, 9} a total of 5 options.
If instead of a 4, the number next to the 3 is a 5, we have:
235_
And the number next to the five can be any digit larger than 5, so now we have 4 options.
If instead of a 5, we have a 6, we will have 3 options to put after the 6.if instead of a 6, we have a 7, we will have 2 optionsif instead of a 7, we have an 8, we will have 1 option.Now, we can't have another number than a 3 in the hundreds place, because if we put a 4 there, we are out of the range, and 3 is the smallest digit that we can use there.
Then we already saw all the possible numbers that we can make, adding the numbers of options that we got above we will get:
5 + 4 + 3 + 2 + 1 = 15
This means that are 15 of these numbers between 2020 and 2400. Then the correct option is C.

how to find the slope from a table of data
The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is [tex]\frac{dy}{dx}[/tex] or:
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Example:
Let's say you're give this table:
x: 1, 2
y: 1, 2
Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1
Do the same for x
Now plug the values taken in the slope formula and you get:
[tex]\frac{2 - 1}{2 - 1}[/tex]
[tex]\frac{1}{1} = 1[/tex]
Therefore the slope is 1.
Answer:
Rise/run
Rise over run.
Step-by-step explanation:
To find the slope pick two perfect spots on the line when the coordinates are not decimals.
Then, take those two points and figure out the distance. You will use rise/run.
so rise is how much you either go up or down and run is how much you either go right or left. so how much you'll go up or down? how much will you move right or left?
Lets say you have to go up 5 and then left 7 to get to the coordinate.
That's your slope! you went up so it's positive and you went left so it's negative. Rise over run : rise 5 left 7 so, 5 and -7 which is 5/-7 and that's your slope!

The probability of drawing a 6 is
(Type a whole number or a simplified action.)
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Probabilities.
Here, In the game of cards, we have total number of 52 cards in a deck. Since here we have to find the probability of Card 6 from the whole deck.
Let's solve,
Total Number of Cards we have = 52
Total number of 6 numbered Cards in deck = 4
Hence, probability = Favourable Outcomes ÷ Total No. of Outcomes.
So, the Probability of getting a 6 Card = 4/52
= 1/13
Hence the probability is 1/13.
