If you would explain your answer, that'd be great, but you can just answer it if you want
Answers
Explanation:
1) domain is all possible x values the graph covers so you can see the arrows point bot direction meaning it will go on forever
2) range is all possible y values so the graph goes all the way up but stops at -4 when going down, but it doesn’t touch 4 so it’s a parenthesis not a bracket (which is used when it’s equal to that number)
3) as x increases in number from negative to positive than y is also increasing (based on the graph)
4) as x decreases it stops a -4 but and doesn’t pass this y value ( it’s finding the limit)
5) x intercept is when y=0
6) y intercept is when x=0

The answer is : 40:10
*multiply by 2
If helpful, brainliest please !
Answer:
40:10 & 8:2
Step-by-step explanation:
20 * 2 = 40
5 * 2 = 10
8 * 2.5 = 20
2 * 2.5 = 5
2:1 does not work because only 2 * 10 = 20, but 1 *10 = 10 and there is no 10. There is only 5.
Kelly bought a cup of coffee and drank 5/8
of it.
Write an addition equation to represent how much coffee is remaining.
Answers
Answer: x+5/8 = 1 is the equation where x is the remaining coffee.
Step-by-step explanation:
he drank = 5/8
whole coffee = 1
so
let coffee remaining be x
1-5/8 = x
x+5/8 = 1
The required equation, for the remaining cup of coffee, is x = 1+(- 5/8).
To determine the addition equation of coffee remaining in the cup, for the condition Kelly bought a cup of coffee and drank 5/8 it.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the coffee remaining in the cup be x,
Now, according to the question,
1 = x + 5/8
x = 1 - 5/8
For the addition equation,
x = 1 +(-5/8)
Thus, the required equation, for the remaining cup of coffee, is x = 1+(- 5/8).

Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds. Which piece of information is missing for the correct calculation of velocity?
A. The Starting point
B. The direction
C. The end point
D. The time per meter
Answers
Answer:
The end point as when we multiply 4.3 x 4.7 we get 20.21 and if there is no end point in distance shown we can assume she displaced 20 meters in 4.7 and that 4.26 seconds had a larger end point.
However a starting and end point is always required.
Step-by-step explanation:
4.7 x 20
Change minutes into seconds (so that the final result would be in meters per second) we do not have to do this as all time is already in seconds.
= 4.7 seconds, Divide the distance by time: velocity = 20/4.7 = 4.25531915
= 4.3 m/s
3/2 = 5d - 1/2
solve for d
Answers
Answer:
D = 2/5 or 0.4
Step-by-step explanation:
3/2 = 5d - 1/2
move the terms
3/2 - 5d = -1/2
calculate the difference
-5d = -2
divide both sides by -5
2 = 2/5
3/2 = 5d - 1/2
+1/2 +1/2
2=5d
divide both sides by 5
D = 2/5

I WILL MARK AS BRAINLIEST! Find the surface area and Volume of the following figures
Answers
Step-by-step explanation:
a) is really easy, right ?
the surface area consists of 6 rectangles (as you know, every die has 6 sides). they are 3 pairs of equally sized rectangles.
there are 2 rectangles 7×1, 2 rectangles 7×2, and 2 rectangles 2×1
SA = 2×7×1 + 2×7×2 + 2×2×1 = 14 + 28 + 4 = 46 in²
the volume is just length×width×height
V = 7×2×1 = 14 in³
b)
a little bit more difficult, but with a little trick just as easy.
the surface area consists of the 2 circle areas and the mantle "coating".
the area of a circle is pi×r².
we have to be careful as the given 10 ft is the diameter of these circles. the radius is half of it : 5 ft.
the area of the "mantle" we can calculate by imagining we simply slice it open with one straight line from top to bottom. and then we cut it off the two circles and put it flat on the table.
now we see it is just a rectangle. one side is 12ft. the other is the circumference of the previously attached circles.
circumference of a circle is 2×pi×r
so the surface area is 2×circle + (circumference circle)×12
SA = 2×pi×5² + (2×pi×5)×12 = 50pi + 120pi = 170pi =
≈ 534.07 ft²
the volume is one base area (circle) times height
V = pi×5²×12 = 300pi ≈ 942.48 ft³

triangle ABC △ABC triangle, A, B, C is rotated -120° about point P create ΔA' B' C'
Answers
Answer:
40°
Step-by-step explanation:
Since triangle ABC is identical to triangle A'B'C', it has the same measures of respective sides and angles, and ang A is therefore equal to angle A'.
After rotational transformation, the measure of angle ∠A' = 40°.
What is a rotation transformation?A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.
For the given situation,
The diagram shows the two triangles.
Triangle ABC is the original triangle and A'B'C' is the triangle obtained after the rotation of -120°.
From the definition, in rotational transformation the size and shape of the figure stays exactly the same. Then the angle measures are also remains the same.
Thus the measure of angle A' is [tex]\angle A' = \angle A = 40[/tex]
Hence we can conclude that after rotational transformation, the measure of angle ∠A' = 40°.
