Remember the f(x) is the same thing as y so...
y = -3x + 5
y = -1
To solve this plug -1 in for y in the equation y = -3x + 5 and solve for x
-1 = -3x + 5
-6 = -3x
2 = x
When f(x) is -1 then x is 2

Can (3,5 and square root 34) be sides on a right triangle?
Answer:
Yes, they are.
Step-by-step explanation:
Remember that a triangle is only a right triangle if its sides meet this mathematical requirement:
(leg)² + (leg)² = (hypotenuse)²
The hypotenuse of a right triangle is the longest side, while the legs are the two shorter sides. We can't say exactly where √34 is, but since √25 = 5 and √36 = 6, we know it must be at least bigger than 5, making it the triangle's longest side.
Using √34 as the "hypotenuse" and 3 and 5 as the "legs" of our triangle makes the equation 3² + 5² = (√34)², and simplifying gets us
9 + 25 = 34
34 = 34
The requirement's been met, so yes, this is a right triangle.
Answer quick please Points N, P, and R all lie on circle O. Arc PR measures 120° How does the measure of angle RNQ relate to the measure of arc PR?
A.Angle RNQ is equal in measure to arc PR.
B.Angle RNQ is half the measure of arc PR.
C.Angle RNQ is twice the measure of arc PR.
D.Angle RNQ is four times the measure of arc PR.
Answer:
Option A. Angle RNQ is equal in measure to arc PR.
Step-by-step explanation:
we know that
The triangle NOR is an equilateral triangle, because has three equal sides
NO=OR=RN ----> radius of the circle O
therefore
The interior angles of the triangle NOR measures 60 degrees each
so
∠RNO=60°
Find the measure of angle RNQ
we have that
∠RNO+∠RNQ=180° ------> by supplementary angles (linear pair)
substitute
60°+∠RNQ=180°
∠RNQ=180°-60°=120°
we know that
arc PR= 120° ----> see the graph
therefore
∠RNQ=arc PR
Angle RNQ is equal in measure to arc PR.

On a DVD, information is stored on bumps that spiral around the disk. There are 73,000 ridges (with bumps) and 73,000 valleys (without bumps) across the diameter of the DVD. What is the diameter of the DVD in centimeters? Round your answer to the nearest whole number.
Answer:18542
Step-by-step explanation:simplemath
The diameter of the circular DVD is d = 12 cm
What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the diameter of the circular DVD be d
The total number of ridges = 73,000
The total number of valleys = 73,000
The width of each ridge = 0.000032 cm
The width of each valley = 0.000074 cm
The length of center portion c = 4.26 cm
And , the diameter of circular DVD = total width of ridges + total width of valleys + center portion
The total width of ridges = ( 0.000032 cm ) x 73,000
The total width of valleys = ( 0.000074 cm ) x 73,000
So , the total width of ridges and valleys = 73,000 ( 0.000106 ) = 7.738 cm
On simplifying , we get
The diameter of circular DVD d = 7.738 cm + 4.26 cm
The diameter of circular DVD d = 11.998 cm
The diameter of circular DVD d ≈ 12 cm
Hence , the diameter of the circular DVD is 12 cm

What is the area of a circle with a radius of 8 inches? Use = 3.14
Answer:
200.96 inch²
Step-by-step explanation:
formula for a circle: (pi) x r²

if a school has w women and M men and you know that there are 100 more men than women write an algebraic equation relating W and M
Answer:
W+100=M
Explanation:
So the problem says there will always be 100 more men than woman. So that would mean you just have to add the amount of women and 100 to find the number of men. For example, if there are 3 women, there will be 103 men.
Hope this helps ;)
Certainly! To create an algebraic equation representing the given situation, we can use the information that there are 100 more men than women at the school.
Let's use the variables:
- \( W \) to represent the number of women
- \( M \) to represent the number of men
The key piece of information that we have is that the number of men is 100 more than the number of women. We can write this relationship with an equation:
\[ M = W + 100 \]
This equation states that if you take the number of women (\( W \)) and add 100 to it, you will get the number of men (\( M \)). It directly translates the information given into an algebraic equation, showing the relationship between the number of women and the number of men in the school.
What system of equations is shown on the graph below?

[tex]m=\dfrac{-2-0}{0-4}=\dfrac{-2}{-4}=\dfrac{2}{4}=\dfrac{2:2}{4:2}=\dfrac{1}{2}[/tex]
Substitute the values of a slope and an y-intercept to the equation of a line:
[tex]y=\dfrac{1}{2}x-2[/tex]
Convert to the standard form [tex]Ax+By=C[/tex]:
[tex]y=\dfrac{1}{2}x-2[/tex] multiply both sides by 2
[tex]2y=x-4[/tex] subtract x from both sides

[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
In this case...
[tex]y_{2} =12\\y_{1} =18\\x_{2} =0\\x_{1} =-3[/tex]
^^^Plug these numbers into the formula for slope...

So, here we will apply this knowledge.
[tex]115\°+12\°+x\°=180\°[/tex]
[tex]127\°+x\°=180\°[/tex]
Now, we will subtract 127° from both sides of the equation, and we get;

[tex]x\°=53\°[/tex]
Therefore,[tex]x=53.[/tex]
The value of x° is 53°.
Hence, the third angle in the given triangle is 53°.

there was a total of 750 and 2015 crickets in a pond, the population increased by 17% the next year. The year after that the population decreased by 10%. what is the percent of change of population from the 2015 to 2017?
Answer:
5.2% increase
Step-by-step explanation:
In 2015 the total population was 750.
In 2016 the total population was 17% more than in 2015, so 750 x 1.17 = 877.
In 2017 the total population was 10% less than in 2016, so 877 x 0.9 = 789.
Compared to 2015, the population in 2017 was 789/750 = 1.052 or 5.2% greater.
In one step:
((750 x 1.17) x 0.9) / 750 = 5.2%
In this question, we're going to need to find the population in 2017, while using the given information.
Answer: 5.3% increaseLets gather the information we should know from the question.
Key information:
2015 -- Population of 750
Increased by 17% in the next year
Decreased by 10% the next year
With the information above, we can solve the problem.
We know that our starting population for crickets is 750, and it increases by 17% for the next year (2016), so we would multiply 750 by 1.17
[tex]750*1.17=877.5[/tex]
Our population in 2016 is 877.5.
Now, we know that he population in 2016 decreased by 10% going into 2017. We would need to find how much of 877.5 is 10%, and then subtract.
[tex]877.5*.10=87.75\\\\877.5-87.75=789.75[/tex]
When you're done solving, you should get 789.75
This means that the population of crickets in 2017 is 789.75.
Now, we know that we started with 750 crickets, now we have 789.5 crickets.
We would divide 789.5 by 750.
[tex]789.5\div750=1.053[/tex]
We would move the decimal place two times to the right, giving us 5.3.
This means that the population increased by 5.3% from 2015 to 2017.
