Answer:
Step-by-step explanation:
The first one.
If line AB and BC are intersecting at point B and ray BD bisect the angle ABC, then the value of x is 23
The line AB and BC are intersecting at point B.
Ray BD bisect the angle ABC
∠ABD = x+8 degrees
∠ABD=∠DBC = x+8
Because the ray BD bisect the ∠ABC, so ∠ABD and ∠DBC will be equal
∠ABD+∠DBC= 4x-30 degrees
Because both are vertically opposite angles
Substitute the values in the equation
x+8 + x+8 = 4x-30
2x+16 = 4x-30
2x-4x = -30-16
-2x = -46
x = 23
Hence, if line AB and BC are intersecting at point B and ray BD bisect the angle ABC, then the value of x is 23
The complete question is

Answer: Domain of the function represented in the graph is given by he inequality . 2 <_ x _< 10
Step-by-step explanation:
we know that
Observing the graph
The domain is the quantity of yellow paint in millimeters
The domain is the interval -----> [2,10]
All real numbers greater than or equal to 2 and less than or equal to 10
therefore 2 <_ x _< 10
my bad I couldn't put the line under the sign
Answer:
The answer to your question is below
Step-by-step explanation:
Domain is the values of x the function can take D = (-2, 2]
Range is the values of y the function can take R = [-5, 4]
a) From the graph we got f(-1) = -5
b) From the graph we got f(0) = -4
c) From the graph we got f(1) = -5
d) From the graph we got f(2) = 4
