Step-by-step explanation:
starting from 3 movies we have 4 possible outcomes: 3, 4, 5, and 6.
We have 6 of the 20 students, who watched 3 movies over the break.
Out of the 20 students, 4 watched 4 movies over the break.
Out of the 20 students, none watched 5 movies over the break.
Lastly, 1 student watched up to 6 movies on the break.
Adding up all the students who watched 3 or more movies on the break, we get 11.
1 + 0 + 4 + 6 = 11

Triangle ABC is isosceles with AB = AC.
Angle BAC = 110° and the area of the triangle is 85cm2.
Calculate AC
If Triangle ABC is isosceles with AB = AC is: 13.45 cm.
Triangle ABC∆ABC = 85 cm² .
(1/2) ×AC×AB ×sinA = 85 cm²
AC=AB=x
Hence:
85= (1/2)x²×sin110°
A² × sin 110° = 170
A² ×0.94 = 170
A² = 170/0.94
A² =√ 180.85
A= 13.45 cm
Therefore if Triangle ABC is isosceles with AB = AC is: 13.45 cm.

Answer:
Equation of Parallel line: y = -5x-34Equation of Perpendicular line: y = 1/5x - 14/5Step-by-step explanation:
a) Equation of Parallel line to the given line and passes through the point (-6, -4)
We know that the slope-intercept form of the line equation is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
Given the line
y = -5x+4
comparing with the slope-intercept form of the line equation
The slope of the line = m = -5
We know that parallel lines have the same slope. Thus, the slope of the line parallel to the line y = -5x+4 will also be: -5
So, the equation of the line parallel to the given line and passes through the point (-6, -4) will be:
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = -5 and the point (-6, -4)
y - (-4) = -5(x-(-6))
y+4 = -5(x+6)
y+4 = -5x-30
y = -5x-30-4
y = -5x-34
Therefore, the the equation of the line parallel to the given line and passes through the point (-6, -4) will be:
y = -5x-34Hence:
Equation of Parallel line: y = -5x-34
a) Equation of Parallel line to the given line and passes through the point (-6, -4)
Given the line
y = -5x+4
comparing with the slope-intercept form of the line equation
The slope of the line = m = -5
We know that a line to perpendicular another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
The slope of new line = – 1/m = -1/-5 = 1/5
So, the equation of the line perpendicular to the given line and passes through the point (-6, -4) will be:
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 1/5 and the point (-6, -4)
y - (-4) = 1/5 (x-(-6))
y+4 = 1/5 (x+6)
Subtract 4 from both sides
[tex]y+4-4=\frac{1}{5}\left(x+6\right)-4[/tex]
[tex]y=\frac{1}{5}x-\frac{14}{5}[/tex]
Therefore, the equation of the line perpendicular to the given line and passes through the point (-6, -4) will be:
[tex]y=\frac{1}{5}x-\frac{14}{5}[/tex]
Hence:
Equation of Perpendicular line: y = 1/5x - 14/5

(3x + 3y = -21
(x + y = -7
Need help asap
Answer: x= -8 and y= 1
Step-by-step explanation:
First, let's work on your first equation,3x+3y=-21
This means, see if it can be simplified at all before attempting to solve it.
Multiply x and 3
Multiply x and 1
The x just gets copied along.
The answer is x
x
3*x evaluates to 3x
Multiply y and 3
Multiply y and 1
The y just gets copied along.
The answer is y
y
3*y evaluates to 3y
3*x+3*y evaluates to 3x+3y
Because of the minus sign
21 becomes - 21
The answer is -21
So, all-in-all, your first equation can be written as: 3x+3y = -21
Now, let's work on your second equation,x+y=-7 x+y evaluates to x+y
Because of the minus sign
7 becomes - 7
The answer is -7
So, all-in-all, your second equation can be written as: x+y = -7
After this initial survey of the equations, the system of equations we'll set out to solve is:
3x+3y = -21 and x+y = -7
Let's start by solving 3x+3y = -21 for the variable x.
Move the 3y to the right hand side by subtracting 3y from both sides, like this:
From the left hand side:
3y - 3y = 0
The answer is 3x
From the right hand side:
The answer is -21-3y
Now, the equation reads:
3x = -21-3y
To isolate the x, we have to divide both sides of the equation by the other variables
around the x on the left side of the equation.
The last step is to divide both sides of the equation by 3 like this:
To divide x by 1
The x just gets copied along in the numerator.
The answer is x
3x ÷ 3 = x
To divide -21-3y by 3
divide each term in -21-3y by 3 term by term.
-21 ÷ 3 = -7
To divide y by 1
The y just gets copied along in the numerator.
The answer is y
-3y ÷ 3 = -y
The solution to your equation is:
x = -7-y
Next, let's solve x+y = -7 for the variable y.
Move the x to the right hand side by subtracting x from both sides, like this:
From the left hand side:
x - x = 0
The answer is y
From the right hand side:
The answer is -7-x
Now, the equation reads:
y = -7-x
To isolate the y, we have to divide both sides of the equation by the other variables
around the y on the left side of the equation.
and this is the final solution to your equation.
Now, plug the earlier result, x=-7-y, in for x everywhere it occurs in
y=-7-x.
This gives y=-7-(-7-y). Now all we have to do is solve this for y,to have our first solution.
Because of the minus sign
7 becomes - 7
The answer is -7
Because of the minus sign
7 becomes - 7
The answer is -7
-7-y evaluates to -7-y
-7 - -7 = 0
The answer is y
-7-(-7-y) evaluates to y
Move the y to the left hand side by subtracting y from both sides, like this:
From the left hand side:
y - y = 0
The answer is 0
From the right hand side:
y - y = 0
The answer is 0
Now, the equation reads:
0 = 0
To isolate the y, we have to divide both sides of the equation by the other variables
around the y on the left side of the equation.
The last step is to divide both sides of the equation by 0 like this:
Sorry, can't divide by zero! Stop! Everything below this line is wrong.
0 ÷ 0 = 1
Sorry, can't divide by zero! Stop! Everything below this line is wrong.
0 ÷ 0 = 1
The solution to your equation is:
1 = 1
Lastly, to find the solution for x, we plug this answer for y into the earlier result that
x=-7-y.
This gives x=-7-(1). Now, simplify this.
Because of the minus sign
7 becomes - 7
The answer is -7
-7-(1) evaluates to -8
x= -8
