How do u find a equation passing through the line in a graph, I will give an example (-2,0) and (0, 5), I don’t understand how to calculate it can u please give me a easy way to do it for me , I’m in the 8th grade
Answers
Answer:
y = 5/2x + 5
Step-by-step explanation:
To find the equation, you first need to find the slope. You can do this by subtracting the two y coordinates (the two last numbers) and using that as the numerator (the top number of the fraction), and then subtracting the two x coordinates (the two first numbers) and using that as the denominator (the bottom number of the fraction). You then have the fraction -5/-2, which can be changed to 5/2 because they are both negative numbers. That is your slope. You then need to find the y-intercept (where the line connects with the y-axis). To do this, you need to figure out what the y (the second number) is when the x (the first number) is 0. In this example, you can already see with the second set of coordinates that the y-intercept is 5 because the x is 0. When this is not easily shown, you can figure out the y-intercept with a table. Sorry if I made it sound too complicated :)

If it took 8 hours to mow 10 lawns, then at that rate, how many lawns could be mowed in 16 hours?
Answers
Answer:
You could mow 20 yards in 16 hours.
Step-by-step explanation:
You can mow 20 yards in 16 hours because half of 16 is 8 and in the question it says that it took 8 hours to mow 10 yards and 8x2=16 so if you multiply 10 by 2 then you would get your answer, 20 yards.
Answer:
20
Step-by-step explanation:
we can find it by using proportions which is the harder way
16/8=x/10
16(10)=8x
160=8x
/8. /8
20=x
20 lawns
The easiest way is that was know 10 lawns is from 8 hours and if we divide 16 by 8 we get 2 so we just have to multiply the 10 lawns by 2 to get 20

Angie bikes for 20 minutes burning 150 calories. How many minutes will it take to burn 525 calories?
Answers
Answer:
70 minutes OR 1 hour and 10 minutes (it's the same thing)
Step-by-step explanation:
So this can be modeled by the equation 20/150=x/525
so solving for x, you have to say whats the most times that 150 will go into 525 without going over
the answer is 3
so 150x3=450 and 525-450=75
75 is one half of 150 so it would be 3.5
multiply 20 by 3.5 and you get 70 or 1 hour and 10 minutes since an hour is 60 minutes
Don't forget to give brainliest :)

HELPPPP PRETTY PLEASEEE ASAP
Answers
Answer: x=230 and y=75
Step-by-step explanation: A triangle is worth 360 degrees, which means when you add up all the angles it equals 360 degrees. So
Second patio:
(x-10),60+80 = 360
x-10+140 =360-140
x-10=220+10
x=230
First patio:
(x+10)+(y+5)+40 = 360
x+y+55=360
x+y=360-55
x+y=305- x(230) =75
y=75
Answer: x = 50, y = 75
The sum of angles of a triangle is equal to 180°
according to the question, (x+10) + (y+5) + 40 = 180 -- eq(1)
(x-10) + 60 + 80 = 180 -- eq(2)
(x - 10) + 140 = 180
x - 10 +140 = 180
x + 130 = 180 , x = 180 - 130
x = 50
put x value in eq(1)
50+10 + (y+5) + 40 = 180
60+(y+5)+40 = 180
y+5 +100 = 180
y + 105 = 180
y = 180 - 105
y = 75
So, x = 50 and y = 75.

There is 40 students in total, so 40/8=5. 5*3=15
15 people suggested, 25 did not
Answer:
15 students suggested a rainbow-themed party.
25 students did not suggest a rainbow-themed party.
Step-by-step explanation:
40 students
3 out of every 8 students suggested rainbow them
40/8 = 5
5 groups = 40 students
1 group = 8 students
3 × 5 (amount of groups) = 15
15 students suggested a rainbow-themed party.
40 - 15 = 25
25 students did not suggest a rainbow-themed party.

What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of sides of the triangle are
AB = 9 m
BC = 11 m
AC = 13 m
Now , for a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
AC² = AB² + BC²
On simplifying , we get
13² = 9² + 11²
169 ≠ 81 + 121
Hence , the sides 9m, 11m, 13m does not form a right triangle

NAG
Answers
Answer:
242 × 4 = 968NAG = 968Step-by-step explanation:
You want the digits assigned to A, D, G, I, N to satisfy the multiplication problem DID·I = NAG.
SolutionNeither D nor I can be 1, because their product is G (not D or I). There can be no carry from that product. (If there were, the result would have 4 digits, not 3.) This means the least significant digit of I·I must be A, and that product must be more than 10.
I² > 10 ⇒ I ≥ 4
I ≥ 4 ⇒ D = 2, G = 8 and I = 4
Then we have ...
DID × I = NAG ⇒ 242 × 4 = 968
The value of NAG is 968.
Answer:
NAG = 968
242 * 4 = 968
2 = D
4 = I

Answers
Answer:
Step-by-step explanation:Answer:
Part a) You could build 5 copies of the flower pattern
Part b) You would have 40 red trapezoids left over
Step-by-step explanation:
The complete question in the attached figure
Part a)
Let
x -----> the number of yellow hexagons
y ----> the number of red trapezoids
z ----> the number of green triangles
we know that
The flower pattern has the following ratios
Find out how many copies of this flower pattern could you build if you had 30 yellow hexagons,50 red trapezoids, and 60 green triangles
1) For x=30
Divide 30 by 6 (remember that in one pattern there are 6 yellow hexagons)
Verify the quantity of y needed and the quantity of z needed
Find the value of y
10 < 50 ----> is ok
Find the value of z
45<60 --->is ok
2) For y=50
Divide 50 by 2 (remember that in one pattern there are 2 red trapezoids)
Verify the quantity of x needed and the quantity of z needed
Find the value of x
150 > 30 ----> is not ok
3) For z=60
Divide 60 by 9 (remember that in one pattern there are 9 green triangles)
60/9=6.7 copies
Round down
6 copies -----> 6(9)=54 green triangles
Verify the quantity of x needed and the quantity of y needed
Find the value of x
36> 30 --->is not ok
therefore
You could build 5 copies of the flower pattern
Part b)
we know that
x:y:z=6:2:9
If you build 5 copies
1) You would use 5*6=30 yellow hexagons and you would have 0 hexagons left over
2) You would use 5*2=10 red trapezoids and you would have (50-10=40) trapezoids left over
3) You would use 5*9=45 green triangles and you would have (60-45=15) triangles left over
therefore
You would have 40 red trapezoids left over
