Answer:
Both angle 1 and 3 are 52 degrees
Step-by-step explanation:
if angle 6 is 128, then so are angle 2, 4, and 8.
if angle 2 is 128, and the whole line is 180, then the missing angle (angle 1) must be 52.
angles 1 and 3 are equal
Answer:
Step-by-step explanation:
Find the y-intercept by setting x = 0: f(0) = 3(4)^0 = 3(1) = 3 => (0, 3)
4^x is never zero, and its graph is always above the y-axis, for both positive and negative x.
Any real number is an acceptable x-value.
Thus the domain is (- infinity, infinity) and the range is (0, infinity).
Use Power of a point.
(can prove using similarity of the triangle)
AC*CB = DC*CE
8*7 = 4*CE
CE = 14
DE = DC+CE = 4+14 = 18
Ans: 18
To determine whether a solution a set of a system of linear inequalities is right, you simply plug back into the equation to check your work. If the solution equals and is mathematically correct, then that's the answer. For Example, use the equation,
5x = 10
Let's say you got an answer of x = 4. Plug it back into the equation
5(4) ≠ 10. As you can see the answer is wrong. This shows you that the answer is wrong.
The correct answer is x = 2
