Step-by-step explanation:
45 >= 4x + 5
40 >= 4x
10 >= x (x <= 10)
and
53 > 4x + 5
48 > 4x
12 > x (x < 12)
so, both conditions need to be true (that is the meaning of "and").
how can that be achieved ? well, the harder, narrower condition beats any other.
so, when x <= 10, then it is automatically also smaller than 12.
so, the solution (inequality notation) is
x <= 10
and the graph just shows a line that starts at 10 (with a full, black dot at 10, as the point is included) and goes all the way to the left (to infinity and beyond ...)

Find the arc length of the partial circle.
Answer:
arc length = 4π units
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × [tex]\frac{90}{360}[/tex]
= 2π × 8 × [tex]\frac{1}{4}[/tex]
= 2π × 2
= 4π units ← exact answer

Please help ME ASAP!!Please explain the answer
Answer:
It seems like you misunderstood the instructions, though I don't blame you because they wrote it strangely. I believe that you're supposed to draw your own conclusion and then explain how you go there, rather than analyze a conclusion that was already drawn for you. If a long drive=a large fare, and you've been told that the driver has a long drive, you can draw the conclusion that "The fare will be large."

Answer:
17 =x
Step-by-step explanation:
These are alternate interior angles and alternate interior angles are equal when the lines are parallel
9x+7 = 10x-10
Subtract 9x from each side
9x+7-9x = 10x-10-9x
7 = x-10
Add 10 to each side
7+10 =x-10+10
17 =x
Please help me solving this problem.
(a) The radius of the circle is the distance the wave travels since it first formed, so if g(t) is the radius of the circle at time t, then it changes at a rate according to
dg/dt = 60 cm/s
Integrate both sides with respect to t to solve for g :
∫ dg/dt dt = ∫ (60 cm/s) dt
g(t) = (60 cm/s) t + C
but C = 0 since the radius at t = 0 must be 0.
g(t) = (60 cm/s) t
(b) The area of any circle with radius r is πr ². So
f(r) = πr ²
(c) The composition of f with g represents the area of water encircled by the wave at time t :
(f o g)(t) = f(g(t)) = π g(t) ²
Use the table to find an quadratic equation of best fit.

y = 1 ( 5th box )
when x is 1:
y = 5(1)+1
y = 6 ( 6th box )
hence true for other values

3.) Find the measure of the missing angle X:
Xº
120°
70°
Answer:
x=50
Step-by-step explanation:
Let's look at the red angle. if a flat line makes the angle 180, and the outer angle is 120, subtract 120 from 180. This will give you 60. Now every angle of a triangle added together will give you the sum of 180. So you already have 60 and 70, which make 130 all together. Subract 130 from 180 - (180-130) - and you'll get the result of 50.
The solution is : the measure of the missing angle X is x=50.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
from the given diagram, we get,
Let's look at the red angle.
if a flat line makes the angle 180, and the outer angle is 120,
subtract 120 from 180.
This will give you 60.
Now every angle of a triangle added together will give you the sum of 180.
So you already have 60 and 70,
which make 130 all together.
Subtract 130 from 180
i.e. (180-130) = 50
and we get the result of 50.
Hence, The solution is : the measure of the missing angle X is x=50.

Is -6/11 a irrational number?
Answer:
No
Step-by-step explanation:
One way to tell if a number is rational is if it can be written as a fraction. Anything that can be written as a fraction of two integers is rational.
-6/11 is a fraction with integer numerators and denominators.
Therefore it is rational.

A measuring cylinder of radius 3cm contains water to a height of 49cm. if this water is poured into a similar cylinder of radius 7cm, what will be the height of the water column
Hey there! I'm happy to help!
Hey there! I'm happy to help!
First, let's find the area of the circle of the first cylinder. To do this, we square the radius and multiply by 3.14.
3²=9
9×3.14=28.26
Now we multiply by our height of 49 cm to see how much water there is.
28.26×49=1384.74
Now, let's find the area of the circle of the 7 cm cylinder.
7²=49
49×3.14=153.86
Now, we will take our liquid amount (volume) and divide by this circle amount (base) to find the number of centimeters of height of the water column.
1384.74÷153.86=9
So, the height of our water column will be 9 cm.

x=0,1,±2
Step-by-step explanation:
x^3(x^2-5)=-4x
x^2(x^2-5)=-4
Take x^2=a, we have
a*(a-5)=-4, a^2-5a+4=0, (a-1)(a-4)=0, a=1,4
x^2=0, 1, 4. x=0,1,±2

x = 1 and x = 2
Step-by-step explanation:

x² = 4 or x² = 1
x = ±√4 = -2 or 2x = ±√1 = -1 or 1Since x > 0, the negative integers are rejected and the solutions to this equations are x = 1 and x = 2

-2 2/5 is more negative than -1 3/5 so it is to the left on the number line
-2 2/5 < -1 3/5 < 1 1/5
11/5 < -2 1/5 is not correct because 1 is bigger than -2
