How do I graph this?
Answer:
So, in order to solve this, you need to know slope. Slope is equal to rise (up/down) over run (left/right). The number at the end, which in this case is 2, is the y-intercept. So, first, graph a point on the y-axis, which is 2. Next, you can place any other point on the line, as long as it follows your slope, which is 3/5. If you need a better explanation, just graph (0, 2) on the y-axis and also graph the point (3, 5).
Have a good one,

Shalah mowed 12 lawns in 3 hours. What is her RATE? *
help me plz
Answer: I think the answer is 4 because usually when you find the rate of something it means you divided the two numbers or however many numbers you have... So, 12 divided by 3 is 4... So, 4 hours for each lawn she mows... or something like that... So, 4 lawns per hour...
Final answer is 4 lawns per hour... If this isn't the correct answer i am very sorry... Stay safe and have a great weekend!!! :D
Answer:
4 lawns per hour
Step-by-step explanation:
4 lawns per hour or 1 lawn per 15 mins.
12/3 is the unit rate so 4/1.
Hope this helps plz hit the crown :D

Find the slope of the line drawn on the graph. If your answer is a fraction, leave in simplified fraction form.
Answer: The slope would be 2/5.
Step-by-step explanation: To find the slope, it's rise divided by run. The 2 points on this graph are (-2,-1) and (3,1). So basically, change in y value, divided by the change in x value.

Select the sequences that are geometric.
18, 36, 54, 72,...
4.1, 8.2, 16.4, 32.8,...
answer:
Both sequences are geometric
Step-by-step explanation:
because both have common differences of 2 times
Answer:
4.1, 8.2, 16.4, 32.8,... is a geometric sequence.
Step-by-step explanation:
Given the first sequence
18, 36, 54, 72,...
we know that the geometric sequence is the sequence that has the same common ratio 'r' (constant ratio).
Computing the ratios of all the adjacent terms:
[tex]\frac{36}{18}=2,\:\quad \frac{54}{36}=1.5,\:\quad \frac{72}{54}=1.33333\dots[/tex]
As the ratio is not constant.
Hence, 18, 36, 54, 72,... is NOT the geometric sequence.
Given the second sequence
4.1, 8.2, 16.4, 32.8,...
we know that the geometric sequence is the sequence that has the same common ratio 'r' (constant ratio).
Computing the ratios of all the adjacent terms:
[tex]\frac{8.2}{4.1}=2,\:\quad \frac{16.4}{8.2}=2,\:\quad \frac{32.8}{16.4}=2[/tex]
As the ratio of all the adjacent terms is the same (constant ratio).
Hence, 4.1, 8.2, 16.4, 32.8,... is a geometric sequence.
Therefore, 4.1, 8.2, 16.4, 32.8,... is a geometric sequence.
Find the 17th term of the arithmetic sequence -12, -8, -4, 0, ...
Answer:
130
Step-by-step explanation:
happy to help :0 have a good day sir
Answer:
52
Step-by-step explanation:
the sequence is increasing by 4
hence, the nth term in n = 4(n) -16
hence, 17th term = 4(17) -16 = 52
2²ˣ = 6ˣ⁻³
How would I convert this to logarithmic form, then solve in log M / log N format?
6 = 2 • 3, so
6ˣ⁻³ = 2ˣ⁻³ • 3ˣ⁻³
Then in
2²ˣ = 6ˣ⁻³
we would have
2²ˣ = 2ˣ⁻³ • 3ˣ⁻³
2²ˣ / 2ˣ⁻³ = 3ˣ⁻³
2²ˣ⁻ˣ⁺³ = 3ˣ⁻³
2ˣ⁺³ = 3ˣ⁻³
Now take the logarithm of both sides. The base you choose doesn't matter.
log(2ˣ⁺³) = log(3ˣ⁻³)
Recall that log(aⁿ) = n log(a), so that the equation reduces to
(x + 3) log(2) = (x - 3) log(3)
Solve for x :
log(2) x + 3 log(2) = log(3) x - 3 log(3)
(log(2) - log(3)) x = - 3 log(2) - 3 log(3)
Recall that log(a) - log(b) = log(a/b), and log(a) + log(b) = log(ab), so that
log(2) - log(3) = log(2/3)
- 3 log(2) - 3 log(3) = - 3 (log(2) + log(3)) = - 3 log(6)
So, we get
log(2/3) x = - 3 log(6)
x = -3 log(6) / log(2/3)
As I mentioned, the base of the logarithm doesn't matter, x will always have the same value of about 13.257.

The longer leg of a 30⁰-60⁰-90⁰ triangle is 5√3 . Find the length of the hypotenuse.
explain how you got it.
Answer:
The answer is 10
Step-by-step explanation:
The longer leg of this triangle is √3 times longer than the shorter leg. Since the longer leg is 5√3, then the shorter leg will be 5. The hypotenuse is twice the size of the shorter leg, so 5*2 is 10.

Ricky draws 24 cartoon Characters
every 3 minutes. Leo draws 28 cartoon
Characters every 4 minutes. Who draws
at a faster rate?
Answer:
Ricky
Step-by-step explanation:
24 divided by 3 equals 8 drawings per minute
28 divided by 4 equals 7 drawings per minute
Answer:
Ricky
Step-by-step explanation:
One way to solve this is finding out how many characters they draw per minute. In order to find this, you must divide the amount of cartoon characters by the time. For example, 24 divided by 3 is 8 and 28 divided by 4 is 7. Ricky draws 8 per min and Leo draws 7 per min. Therefore, Ricky draws at a faster rate. Hope this helps! :)

What is the solution of 9x – 8 = 34x – 12?
Answer:
Step-by-step explanation:
Let
V
be the number of vertices of a polyhedron,
F
the number of faces of that polyhedron, and
E
be the number of edges. The quantity
χ
=
V
−
E
+
F
is called the Euler characteristic (of a polyhedron). In the case of convex polyhedra,
χ
=

Consider, for example, a tetrahedron (which is the simplest solid). It has 4 faces,

(

edges, and

F

−
6
+
4
=
2
.
Euler's formula holds for all Platonic solids (tetrahedron, cube, octahedron, dodecahedron, and icosahedron). Since a cube and an octahedron are dual polyhedra (each is formed by connecting the centers of the faces of the other), their
V
and
F
values are equal to the
F
an
V
values of the other. (The same is true for the dodecahedron and icosahedron).
