ABC is an equilateral triangle .Three distinct points are marked on each sides of the triangle. (not on the vertices). (i) How many lines can be drawn joining 2 of these nine points? [3 marks] (ii) Find the number of different triangles that can be formed using of 3 of these nine points as vertices. [3 marks]
Answers
The number of lines and triangles illustrates combination
36 lines can be drawn to join the nine points84 triangles can be drawn using the nine pointsThe number of lines that can be drawn
The given parameters are:
Total points, n = 9
Total points on each line, r = 2
The number of lines that can be drawn is then calculated using the following combination formula
Lines = nCr
This gives
Lines = 9C2
Evaluate the combination expression
Lines = 36
Hence, 36 lines can be drawn to join the nine points
The number of triangles that can be drawnThe given parameters are:
Total points, n = 9
Total points on each triangle, r = 3
The number of triangles that can be drawn is then calculated using the following combination formula
Triangles = nCr
This gives
Triangles = 9C3
Evaluate the combination expression
Triangles = 84
Hence, 84 triangles can be drawn using the nine points

9×(x+7)+5=86.can you help me to solve this question.
Answers
Answer: x=2
Step-by-step explanation:
9(x+7)+5=86
Step 1: Simplify both sides of the equation.
9(x+7)+5=86
(9)(x)+(9)(7)+5 (Distribute)
9x+63+5=86
(9x)+(63+5)=86 (Combine Like Terms)
9x+68=86
Step 2: Subtract 68 from both sides.
9x+68−68=86−68
9x=18
Step 3: Divide both sides by 9.
[tex]\frac{9x}{9} =\frac{18}{9}[/tex]

Which of these statements is a valid perfect square trinomial?
Statement 1: x2 + 10x + 100 = (x − 10)2
Statement 2: a2 + 2ab + b2 = (a + b)2
Group of answer choices
Statement 1 and statement 2 are valid.
Statement 1 and statement 2 are invalid.
Only statement 1 is valid.
Only statement 2 is valid.
Answers
Answer:
D. Only statement 2 is validStep-by-step explanation:
Verify if the statements are correctStatement 1:
x² + 10x + 100 = (x − 10)²x² + 10x + 100 = x² + 2(x)(-10) + (-10)²x² + 10x + 100 = x² - 20x + 100LHS ≠ RHSStatement 2:
a² + 2ab + b² = (a + b)²a² + 2ab + b² = a² + 2ab + b²LHS = RSHAs we see the second statement is valid but not the first one.

2 tan x - Sin 2x ÷ 2 Sin^2 x = tan x
Answers
Looks like the claim is
(2 tan(x) - sin(2x)) / (2 sin²(x)) = tan(x)
Recall the double angle identity for sine:
sin(2x) = 2 sin(x) cos(x)
as well as the definition of tangent:
tan(x) = sin(x) / cos(x)
Then on the left side, we can cancel factors of 2 sin(x) to get
(2 sin(x) / cos(x) - 2 sin(x) cos(x)) / (2 sin²(x))
= (1/cos(x) - cos(x)) / sin(x)
Multiply this by cos(x)/cos(x) :
(1/cos(x) - cos(x)) / sin(x) = (1 - cos²(x)) / (sin(x) cos(x))
Recall that for all x,
sin²(x) + cos²(x) = 1
so that
(1 - cos²(x)) / (sin(x) cos(x)) = sin²(x) / (sin(x) cos(x))
= sin(x) / cos(x)
= tan(x)

1. Ms. Rowel would like to buy a house costing $190000. She is required to make a down payment equal
to 10% of the value of the house then borrow the balance from a bank that charges interest at an annual
rate of 4.2% compounded monthly. The bank loan has to be paid o§ with equal monthly payments,
(paid at the end of each month), in 30 years. Assume that she will get the loan at the beginning of a
month and start making monthly payments on the last day of each month until the loan is paid o§
Answers
Answer:
the monthly payment would be 836.22
Step-by-step explanation:
you would find the loan amount which is 190,000 -10% of 190,000 which is 190,000 - 19,000=171,000
then you put the numbers in on a calculator which im using a spreadsheets/ excel
you need to make sure that you divide 12 for the interest and multiply 12 to the 30 years to get the monthly value of them

For which value of h will the equation below
result in an infinite number of solutions?
(3x - 8)h = -27x + 72
Answers
Answer:
h = -9
Step-by-step explanation:
Try to make the left hand side and the right hand side equal. By dividing like
h = (-27x+72)/(3x-8)
= [-9(3x-8)]/(3x-8)
= -9
When both sides are equal, you can't find the value of x as there are infinitely many solutions of x.

as the value of the slope gets bigger.
A. steeper
B. longer
C. less steep
D. shorter
Answers
Answer: Less Steep
Step-by-step explanation: the graph of a line gets less steep as the value of the slope gets bigger.
The graph of the line gets steeper as the value of the slope gets bigger. Then the correct option is A.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
If the value of the slope is bigger then the line will be steeper.
Thus, the correct option is A.

To find the volume of a rectangular prism the formula is V=whl . So to find the dimensions of the box we would have to take the options that they give us and see which ones equal 80 cubic cm.
2⋅5⋅8=80, so right away we know the answer because 5⋅2=10 and 10⋅8=80
4⋅5⋅4=80, that is another possible answer because 5⋅4=20 and 20⋅4=80
10⋅4⋅2=80, yet another answer that is equivalent to 80 because 10⋅4=40 and 40⋅2= 80
So now we know that all three answers are correct and they would all work as possible dimensions for Max’s box.
