Answer:
Step-by-step explanation:
Th average rate of change is the slope of the secant line that goes through those 2 values of x. Of course, each value of x also has a value of y. The coordinates for these combinations of x's and y's are:
(-1, 5) and (4, 0). We can use the slope formula to find the average rate of change of this function without having to know what the function's equation is:
So the average rate of change, aka slope, between those 2 points is -1

Answer: 13
Step-by-step explanation:
In order to solve this equation you need to replace x with 9.
2/3 x 9 + 7=
6 + 7=

Answer:
4 cm
Step-by-step explanation:
- PQ = 8 cm
- QR = 10 cm
- Height corresponding to PQ = 5 cm
- Height corresponding QR = x
The area of parallelogram is equal to product of its base and height
It can be expressed as
and
Comparing them we get
Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
The triangle ABC is a right triangle
we have that
step 1
Find the length side b
The cosine of angle A is equal to divide the adjacent side angle A (side b) by the hypotenuse (side c)
so
substitute the given values
solve for b
step 2
Find the length side a
The sine of angle A is equal to divide the opposite side angle A (side a) by the hypotenuse (side c)
so
substitute the given values
solve for a
step 3
Find the measure of angle B
we know that
----> by complementary angles
substitute the value of A
