A dance squad needs at least $800 to buy new dance outfits.
They have saved $350 already.
They are selling tickets to a dance performance for $8 each.
They need to sell x tickets to have enough money to buy the new dance outfits. Which inequality represents this situation?
A
8x+350≤800
B
8x+350≥800
C
8(x+350)≤800
D
8(x+350)≥800
Answer:
B) 8x + 350 ≥ 800
Step-by-step explanation:
A dance squad needs at least $800, this means the inequality sign will be greater than or equal to.
They already have $350, and each ticket is $8.
So,
8x + 350 ≥ 800

If you were to write the slope-intercept equation for a line that goes through the point (4,-3)--with a slope of -2--what would be the value of b?
y=mx+b
y=-2x+5 is the slope-intercept equation for a line that goes through the point (4,-3) and 5 is the value of b.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We have to find the slope-intercept equation for a line that goes through the point (4,-3)--with a slope of -2
m=-2
Now let us find the y intercept
-3=-2(4)+b
-3=-8+b
-3+8=b
5=b
Hence, y=-2x+5 is the slope-intercept equation for a line that goes through the point (4,-3) and 5 is the value of b.

if m<xyz = 58 and m<wxz = 51 find m<wzx
Answer:
m<wzx = 71
Step-by-step explanation:
Assuming these are interior angles of a triangle.
The sum of all three interior angles of a triangle is always 180 degrees, therefore:
m<xyz + m<wxz + m<wzx = 180
Substitute our values:
58 + 51 + m<wzx = 180
m<wzx = 180 - 58 - 51
m<wzx = 71

the solutions to the equation have value of a=-4, b=1 and c=38.
define factorizationIn mathematics, factorization is the process of finding the factors of a given mathematical object, such as a number, polynomial, or matrix. Factors are objects that can be multiplied together to obtain the original object.
To solve the equation x² + 8x = 38 for x, we can use the following steps:
Move the constant term to the other side of the equation:
x² + 8x - 38 = 0
Using quadratic formula:x=(-b±√b²-4ac)/2a
x=(-8±√64-4×1×(-38))/2×1
x=-4+√38
or x=-4-√38
On comparing with x= a+ b √c
x= a- b √c
value of a=-4
b=1
c=38
Therefore, value of a=-4, b=1 and c=38.

P(A and B) is equal to 6.
To find P(A and B), we can use the formula:
P(A and B) = P(A) + P(B) - P(A U B)
Given the information:
P(A U B) = 32 (the probability of either event A or event B occurring)
Universal set contains 52 elements (total number of possible outcomes)
P(A intersection B) = 6 (the probability of both event A and event B occurring)
P(A) = 12 (the probability of event A occurring)
P(B) = 26 (the probability of event B occurring)
We can substitute the known values into the formula:
P(A and B) = P(A) + P(B) - P(A U B)
P(A and B) = 12 + 26 - 32
Simplifying the expression:
P(A and B) = 38 - 32
P(A and B) = 6
Therefore, P(A and B) is equal to 6.
The result indicates that the probability of both event A and event B occurring simultaneously is 6 out of the total number of possible outcomes in the universal set. It means that out of the 52 elements in the universal set, 6 of them satisfy the conditions of both A and B.

What is vertical stretch factor?The vertical stretch factor is a term used in mathematics to describe the transformation that changes the height of a graph while leaving the horizontal axis unchanged. In other words, it's a factor by which the y-values of a function are multiplied to produce a new, stretched or compressed version of the original graph.
The stretch factor is usually represented by the symbol "k". For example, if the equation of a function is y = f(x), then the equation of its vertically stretched image would be y = k * f(x). A positive value of k stretches the graph upward, while a negative value of k compresses the graph downward. If k > 1, the graph is stretched vertically; if 0 < k < 1, the graph is compressed vertically; if k = 1, the graph remains unchanged.

What is a polygon ?
The definition of a polygon is a closed, two-dimensional, plane shape created by connecting three or more line segments. During our study of geometry, polygons are a common sight.
A polygon's sides are constructed from segments of straight lines joined end to end. The sides or edges of a polygon are the line segments that make up its shape. The vertex or corners formed by two line segments are where an angle is created. A triangle with three sides is an illustration of a polygon.
There are 11 sides, So, n=11
Sum of the Interior Angles of a Polygon = 180 (n-2) degrees
