Answer:
105 students and 150 guests
Step-by-step explanation:
equation to find the answer are
1x + 5y = 855
x + y = 255
with
x + y = 255
x = 255 - y
now we replace x with (255 - y) into 1x + 5y = 855 to find y
1(255 - y) + 5y = 855
255 - y + 5y = 855
255 + 4y = 855
4y = 855 - 255
4y = 600
y = 150 (number of guests)
now we got y = 150, let's find x
x + y = 255
x + 150 = 255
x = 255 - 150
x = 105 (number of students)

[tex] \frac{ - 7}{5} [/tex]
on the number line
Answers
Given:
The number is [tex]-\dfrac{7}{5}[/tex].
To find:
The location of the given number of the number line.
Solution:
We have,
[tex]Number=-\dfrac{7}{5}[/tex]
It can be written as
[tex]Number=-\dfrac{5+2}{5}[/tex]
[tex]Number=-\dfrac{5}{5}-\dfrac{2}{5}[/tex]
[tex]Number=-1-\dfrac{2}{5}[/tex]
It means the number is less than -1 but more than -2. So, the number lies between -2 and -1.
The mixed fraction form of given number is
[tex]Number=-(1+\dfrac{2}{5})[/tex]
[tex]Number=-(1\dfrac{2}{5})[/tex]
[tex]Number=-1\dfrac{2}{5}[/tex]
Divide the number in 5 equal parts between two consecutive integers.
Now each unit represents [tex]\dfrac{1}{5}[/tex].
Since [tex]Number=-1-\dfrac{2}{5}[/tex], therefore, it is 2 units left from -1.
The number line is given below.

Step-by-step explanation:
To solve this equation, since m is negative you need to get rid of that negative by dividing each side by -1. this will leave m and make 15, -15. so the equation will be c, m is less than or equal to -15.

A right triangle has side lengths d, e, and f as shown below. Use these lengths to find sinx, tanx, and cosx.
Answers
Step-by-step explanation:
In the given triangle,
Perpendicular = d
Hypotenuse = e
Base = f
We need to find the values of sinx, tanx and cosx.
We know that,
[tex]\sin \theta=\dfrac{P}{H}\\\\\tan\theta=\dfrac{P}{B}\\\\\cos\theta=\dfrac{B}{H}[/tex],
We have, P = d, H = e and base = f
So,
[tex]\sin \theta=\dfrac{d}{e}\\\\\tan\theta=\dfrac{d}{f}\\\\\cos\theta=\dfrac{f}{e}[/tex]
Hence, this is the required solution.
Using the lengths given, the Trigonometry ratios of the right triangle are:
sin x = d/e cos x = f/etan x = d/fRecall:
In a right triangle where we are given a reference angle, ∅, with three sides, we can solve the triangle using the Trigonometry ratios given as: SOH CAH TOA.Given the following:
∅ = xOpposite = dHypotenuse = eAdjacent = fThus:
sin x = Opp/Hyp = d/e (SOH)
cos x = adj/Hypo = f/e (CAH)
tan x = Opp/Adj = d/f (TOA)
Therefore, using the lengths given, the Trigonometry ratios of the right triangle are:
sin x = d/e cos x = f/etan x = d/fLearn more about Trigonometry ratios on:

What is the equation of the axis of symmetry of the parabola y=-2x^2+8x-7?
x=.....
Answers
Answer:
Equation of axis of symmetry is x = 2
Step-by-step explanation:
The equation of the parabola is given as;
y = -2x² + 8x - 7
The equation of the axis of symmetry is given by;
x = -b/2a
In the parabola equation given and using letters of quadratic equation, we can say that;
a = - 2
b = 8.
c = -7
Thus;
x = -b/2a = -8/(2 × - 2)
x = 8/4
x = 2
Equation of axis of symmetry is x = 2
which function defines the sequence -16,-22,-28,-34 where f(10)= -70
Answers
Answer:
f(n) = -6n - 10.
Step-by-step explanation:
This is arithmetic sequence with first term a1 = -16 and common difference d = -6.
So f(n) = a1 + d(n - 1)
= -16 - 6(n - 1)
= -16 - 6n + 6
= -6n - 10.
Checking:
f(10) = -6(10) - 10 = -70.
The function that defines the sequence is f(n) = -6n - 10.
What is an Arithmetic Sequence ?A sequence of numbers which have a relation between them and the consecutive numbers increase or decrease by a fixed amount is called as an Arithmetic Sequence.
The sequence given is -16,-22,-28,-34
This is arithmetic sequence
first term a1 = -16
common difference d = -6.
The nth term of an arithmetic sequence is given by
f(n) = a1 + d(n - 1)
f(n) = -16 - 6(n - 1)
f(n)= -16 - 6n + 6
f(n)= -6n - 10.
To verify this
f(10) = -6(10) - 10 = -70.
Therefore , The nth term is given by f(n)= -6n - 10.

Write the linear equation in standard form:
Answers
Answer:
y= -2x + 11
Step-by-step explanation:
standard form for lines is y=mx+b
m is the slope and b is the y intercept
we already know that m is -2, so we just need to figure out the intercept.
the point given is (7,-3)
points are written as (x,y) so we can plug it into the equation with 7 for the x and -3 for y
-3 = -2 (7) + b
-3 = -14 + b
11 = b
so the equation is y=-2x+11
