y = -2x - 6
2x + y = 5
Step 2: Solve for x
Substitution
Substitute in y: 2x + (-2x - 6) = 5Combine like terms: -6 ≠ 5Here we see that -6 does not equal 5.

Step-by-step explanation:
A set of data has 50 observations. How many classes would you recommend?
Answer:
6 classesStep-by-step explanation:
If k is the number of classes and n is the number of observations, then for number of classes we should select the smallest k such that 2^k > n.
We have n = 50 and:
2^5 = 32 < 502^6 = 64 > 50As per above described 2 to k rule, we are taking k = 6.
So 6 classes should be used.

Answer:
42 degrees
Step-by-step explanation:
All the interior angles in a triangle add up to 180 degrees. Knowing this, we can construct the following equation:
[tex]180=84+54+a\\180=138+a[/tex]
Subtract both sides by 138
[tex]180-138=138+a-138\\42=a[/tex]

What is the equation of the line in slope intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = -x
Step-by-step explanation:
(0, 0) and ( -100, 100)
m= (y2-y1)/(x2-x1)
m=(100-0)/( -100 -0)
m = 100/ -100
m = -1
y - y1 = m(x - x1)
y - 0 = -1(x - 0)
y - 0 = -x + 0
y = -x

if PQ and PR are tangent to circle S,find PQ
Answer:
From one point, you can draw two tangents to a circle. These two tangents will be equal.
Step-by-step explanation:
7x - 24 = 57 - 2x.
Rearrange the numbers (by adding 2x and 24 on both sides), we get:
7x+2x = 57 + 24
9x = 81.
x = 9.
Length of PQ = 57-2x = 57 - 18 = 39
If PQ and PR are tangent to circle S, then the value of PQ is 39.
What is tangent?"A line that touches the circle at a single point is known as a tangent to a circle."
What is circle?"A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre."
P is the exterior point of a circle.
PQ and PR are the tangents to circle S.
According to theorem,
The lengths of the tangents drawn from a same external point to a circle are always equal.
7x - 24 = 57 - 2x
7x + 2x = 57 + 24
9x = 81
x = 9
PQ = 7x - 24
PQ = 7(9) - 24
PQ = 63 - 24
PQ = 39
Hence, the value of PQ is 39.

What expression could be used to evaluate 9/10-1/6
Using the diagram below, which of the following proportionality statements are true? Select all that apply.
Answer:
The proportionality statement which is true is;
(B) [tex]\dfrac{G'H'}{GH} = \dfrac{E'F'}{EF}[/tex]
Step-by-step explanation:
From the diagram, given that the two pentagons are similar, we have;
1. [tex]\dfrac{DH}{D'H'} = \dfrac{EF}{E'F'}[/tex]
2. [tex]\dfrac{DE}{D'E'} = \dfrac{GH}{G'H'}[/tex]
By similarity of the two polygons, we can get the following statements from among the options;
3. [tex]\dfrac{G'H'}{GH} = \dfrac{E'F'}{EF}[/tex]
Therefore, the proportionality statement which is true from the given is the statement;
[tex]\dfrac{G'H'}{GH} = \dfrac{E'F'}{EF}[/tex]
The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $8 and each adult ticket sells for $10.50. The auditorium can hold a maximum of 105 people. The drama club must make at least $990 from ticket sales to cover the show's costs. If 65 adult tickets were sold, determine the minimum number of student tickets that the drama club must sell in order to meet the show's expenses.
Answer:
You need to sell 39 Student tickets minimum to be able to cover the cost over all.
Step-by-step explanation:
If they sell 65 adult tickets, then you have to do 65 x 10.50 = $682.5
with that in mind you will take 308 + 682.5 because that equals 990.5 that would be the minimum amount but you would need to to take 39 x 8 to get 312 because 38 x 8 is 304 so that isn't enough.

In circle H with m \angle GHJ= 34m∠GHJ=34 and GH=11GH=11 units, find the length of arc GJ. Round to the nearest hundredth
Answer:
2.75unitsStep-by-step explanation:
Find the diagram attached
The length of an arc is expressed as shown;
[tex]L = \frac{\theta}{360} * 2 \pi r[/tex]
r is the radius = length of GH
r = GH = 11units
m<GHJ = 34 degree
Substitute the given parameters into the equation given;
[tex]L = \frac{\theta}{360} * 2 \pi r[/tex]
[tex]L = \frac{34}{360} * 2(3.14)(11)\\ L = \frac{34}{360} * 29.08\\L = \frac{988.72}{360}\\L = 2.75 units\\[/tex]
Hence the length of the arc to the nearest hundredth is 2.75units
