Answer:
it would also be 3/4x (in terms of y=mx+c)
Step-by-step explanation:
parallel lines have the same slope/gradient
Answer:
c = 9.43 cm
Step-by-step explanation:
Here, we want to get the measure of the missing side
By the use of Pythagoras’ theorem, the square of the hypotenuse equals the sum of the squares of the two other sides
we have this as follows;
The side c represents the hypotenuse as it faces the hypotenuse
We have this as;
c^2 = 5^2 + 8^2
c^2 = 25 + 64
c^2 = 89
c = √89
c = 9.43 cm
A) 2007
b) 120
c) the donations are decreasing as years increase
Answer:
x = 2.24
Step-by-step explanation:
I will ASSUME that the 15 represents the angle in degrees
We can make a similar triangle by adding the purple lines as shown.
Any triangle inscribed in a circle with one side as a diameter is a right triangle.
We know it is similar triangle because it shares two common angles, the right angle and the 75° angle at the far right. Then
z = 2Rsin15 = 2(16.7)sin15
x = zsin15 = 2(16.7)sin²15 = 2.237375756799...
x / x² - 2x - 15 - 4 / x² + 2x - 35
FIND THE FACTOR OF EACH DENOMINATOR
= x / (x-5)(x+3)
- 4 / (x-5) (x+7)
FIND THE LCD AND MULTIPLY EACH TERM TO ARRIVE AT THE SAME DENOMINATOR.
= x / (x-5)(x+3) *
(x+7) / (x+7) - 4 / (x-5) (x+7) * (x+3)/(x+3)
PERFORM SUBTRACTION
= x2 + 7x / (x-5) (x+3) (x+7) - (4x + 12) / (x-5) (x+7) (x+3)
= x2 + 7x – 4x – 12 / (x-5) (x+3) (x+7)
this would be your answer = x² + 3x – 12 / (x-5) (x+3) (x+7)
