F(x) = a.x . We ha to calculate a.
Back to the table, let's rewrite the coordinates
A(0,0)
B(2,-1)
C(4,-2)
D(7,-3.5)
We know that constant is called slope or coefficient is equal to:
a=y/x
Apart from A, in each of the coordinates y/x =-1/2 & this is the slope of the equation f(x) = (-1/2)x
Answer:
(3x+5)(3x−5)
Step-by-step explanation:
Answer:
the area of the small square 4c
the total area of the 4 triangles is 2ab
a^2+2ab+b^2 = a^2+2ab+b^2
subtracting gives 2ab from both sides gives us a^2+b^2
Step-by-step explanation:
Answer:
Complete the square on x by adding <u>49</u> to both sides.
Complete the square on y by adding <u>81</u> to both sides.
Step-by-step explanation:
We have been given an equation
. We are asked to complete the squares for both x and y.
We know to complete a square, we add the half the square of coefficient of x or y term.
Upon looking at our given equation, we can see that coefficient of x is 14 and coefficient of y is 18.


Now, we will add 49 to complete the x term square and 81 to complete y term square on both sides of our given equation as:

Applying the perfect square formula
, we will get:

Therefore, We can complete the square on x by adding <u>49</u> to both sides and the square on y by adding <u>81</u> to both sides.
Complementary angles - the sum of two angles equals 90 degrees
Exterior angle theorem- the sum of the remote interior angles of a triangle equals the outside angle
Isosceles triangle- has two equal sides and two equal angles
Supplementary angle- the sum of two angles equals 180 degrees
Triangle sum theorem- the sum of of interior angles equal 180
Vertical angles- congruent angles that are opposite of each other.
