Answers
Answer:
right triangle it is because if u make a graph and put the points u would get a right isosclses triangle
Step-by-step explanation:
The triangle ABC with verticies A(3, 3), B(6, 9) and C(6, -3) is an isosceles triangle.
What is the way of classifying a triangle?If a² + b² < c² then it is an acute angle triangle.
If a² + b² = c² then it is a right-angle triangle.
If a² + b² ≥ c² then it is an obtuse angle triangle.
Given, A ΔABC with verticies A(3, 3), B(6, 9) and C(6, -3).
We know the distance formula [tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex].
From this we find AB = √45 units, BC = 12 units and AC = √45 units.
Now, this is an isosceles triangle with two equal sides of √45 units.

Answers
Answer:
(-2, 3)
Step-by-step explanation:
First solve one equation for y:
[tex]-2x+y=7\\y=7+2x[/tex]
Now we can substitute this equation into the other one:
[tex]3x+7+2x=-3[/tex]
Solve for x:
[tex]x=-2[/tex]
Now substitute this value into the equation [tex]y=7+2x[/tex]:
[tex]y=7+2x(-2)[/tex]
Solve for y:
[tex]7=3[/tex]
Now your solution is (-2,3)

Find the value of x
12
5
X
Answers
Answer:
x = 13
Step-by-step explanation:
Note that the side length x is opposite of the right angle, which means that it is the hypotenuse, which will usually be denoted as c.
Set the equation:
a² + b² = c²
let:
a = 5
b = 12
c = x
Plug in the corresponding numbers (& x) to the corresponding variables:
(5)² + (12)² = (x)²
Simplify. First, solve for the power, and then add:
x² = (5²) + (12²)
x² = (5 * 5) + (12 * 12)
x² = 25 + 144
x² = 169
Next, root both sides of the equation:
√x² = √169
x = √169 = √(13 * 13) = 13
x = 13
~
Note the rules, and it should be easier:
30-60-90° = 1 , √3 , 2
45-45-90° = 1 , 1 , √2
Any other measurements use the equation: a² + b² = c²

1.How do you know you have a direct variation in the
relationship between two quantities?
Answers
Answer:
Say you have y=2x. That is direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2x to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.
Step-by-step explanation:
What is the rate of change of the table shown?
Answers
Answer: rate of change = 2
===============================
Explanation:
Apply the slope formula. I'll use the first two columns as the two points, but you can use any two columns you want.
m = (y2-y1)/(x2-x1)
m = (9-5)/(3-1)
m = 4/2
m = 2
The slope is 2, so the rate of change is 2. Slope and rate of change describe the same thing. Each time x goes up by 1, y goes up by 2.

Answer:
x = 18√2y = 18√3z = 36Step-by-step explanation:
These "special" right triangles have side length ratios that it is useful to remember.
45°-45°-90° triangle
Sides have the ratios 1 : 1 : √2. That is, x is √2 times as long as the side length shown as 18.
x = 18√2
30°-60°-90° triangle
Shortest to longest, sides have the ratios ...
1 : √3 : 2
That is, y is √3 times the length of the side marked 18, and z is 2 times the length of the side marked 18.
y = 18√3
z = 2·18 = 36

Answers
Answer: B. 5 ∙ y + 5 ∙ 2 + 4
Step-by-step explanation:
The options are:
a. 5 + y + 5 + 2 + 4
b. 5 ∙ y + 5 ∙ 2 + 4
c. 5 ∙ y + 5 ∙ 4 + 4
d. 5 ∙ y + 5 + 2 + 4
To solve the question, we have to expand 5(y+2)+4. This will be:
= (5 × y) + (5 × 2) + 4
= 5 ∙ y + 5 ∙ 2 + 4
= 5y + 10 + 4
= 5y + 14
