Prove that the bisector of the vertical angle of isosceles triangle is the perpendicular bisector of the base
Answer:
We will take two angles and name them 'x'
And their sum must equal 180
So,
x + x = 180
2x = 180
x = 180/90
x = 90
Hence, it is proved that the bisector of the vertical angle of isosceles triangle is the perpendicular bisector of the base.

Answer:
(0,-5)
Step-by-step explanation:
To find midpoint the formula is
([tex]\frac{x1+x2}{2}[/tex] , [tex]\frac{y1+y2}{2}[/tex])
So plug in the numbers
([tex]\frac{2+(-2)}{2}[/tex], [tex]\frac{-1+(-9)}{2}[/tex]) = ( [tex]\frac{0}{2}[/tex] , [tex]\frac{-10}{2}[/tex])
Simplify it and it equals (0,-5)
A total of 388 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?
Answer:
97
Step-by-step explanation:
388 (number of tickets) / 4 (number of groups (adults, and the 3 times as many kids))
If the number of student tickets sold was three times the number of adult tickets sold, 97 adult tickets were sold.
Let's assume the number of adult tickets sold is 'x.'
According to the information given, the number of student tickets sold was three times the number of adult tickets sold. So, the number of student tickets sold is 3x.
The total number of tickets sold is the sum of the adult and student tickets, which is 388:
x + 3x = 388
Now, combine like terms:
4x = 388
To find the value of 'x,' divide both sides of the equation by 4:
x = 388 / 4
x = 97
To verify the result, let's find the number of student tickets:
Number of student tickets = 3 * 97 = 291
Now, let's add the adult and student tickets:
97 (adult) + 291 (student) = 388
The result checks out, and we have 97 adult tickets and 291 student tickets, which together sum up to the total of 388 tickets sold for the school play.

A line contains L(-4, -4) and M(2,3). Line q is in the same coordinate plane but does not intersect LM. Line q contains point N.
A general line equation can be written as:
[tex]y = a*x + b[/tex]
Where a is the slope and b is the y-intercept.
Here we will find that for N(x₁, y₁), the line q is:
[tex]y = \frac{7}{6}*x + (y_1 - \frac{7}{6}*x_1)[/tex]
If we know that the line passes through the points (x₁, y₁) and (x₂, y₂), then we can write the slope as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
In this case, we know that the line passes through (-4, -4) and (2, 3), then the slope is:
[tex]a = \frac{3 - (-4)}{2 - (-4)} = \frac{7}{6}[/tex]
So the line is something like:
[tex]y = \frac{7}{6} *x + b[/tex]
To find the value of b, we can use one of the two points, for example (2, 3) means that when x = 2, y must be equal to 3, then we can replace these two in the line equation to get:
[tex]3 = \frac{7}{6}*2 + b\\\\3 = \frac{7}{3} + b\\\\3 - \frac{7}{3} = b = 2/3[/tex]
Then the line LM is;
[tex]y = \frac{7}{6}*x + \frac{2}{3}[/tex]
Now we know that line q is in the same coordinate plane, but does not intersect LM. This means that these lines are parallel, and remember that two parallel lines have the same slope, then the slope of line q is also 7/6.
Now we know that line q passes through point N, but we do not know the coordinates of point N, then let's use general coordinates as N(x₁, y₁)
Then line q will be:
[tex]y = \frac{7}{6}*x + c[/tex]
To find the value of c we use the point N.
[tex]y_1 = \frac{7}{6}*x_1 + c\\\\y_1 - \frac{7}{6}*x_1 = c[/tex]
Then the equation of line q is:
[tex]y = \frac{7}{6}*x + (y_1 - \frac{7}{6}*x_1)[/tex]

Add dress and shoes together:
30 + 25 = 55
1/5 off means the total after discount would be 4/5 ( 1 - 1/5 = 4/5)
Multiply total price by 4/5:
55 x 4/5 = (55 x4)/5 = 220/5 = 44
Total after discount is 44
Now add shipping:
44 + 8 = 52
Total paid = £52
Answer:
She will pay $52
Step-by-step explanation:
So she buys them both, which equals 55 dollars. But the website has a deal that is if you buy both of them it's 1/5 of the price off. And 1/5 of 55 is $11, so 55-11=44. You might think you're done but your not. At the end it says they add $8 for the shipping/handling, which is 44+8. This equals 52 dollars. By the way substitute this money sign $ for the one on your page

If f(x) = 9^x , them prove that : f(m+n+p) = f(m) × f(n) × f(p) .
Answer:
f(m+n+p) = 9^(m+n+p)
while f(m) × f(n) × f(p) = 9^m+9^n+9^p = 9^(m+n+p)
