16 because 40-12=28 and Samad will be 28 on 16 years. In 16 years his father will be 56 which is double of 28.
Answer:
9 = X -1 X = 10
Step-by-step explanation:
Add one to both sides
Answer:
Option A k=5
Step-by-step explanation:
step 1
Find the equation of f(x)
we have the points
(-10,-6) and (0,4)
Find the slope m
The function in slope intercept form is equal to
we have
-----> the point (0,4) is the y-intercept
substitute
step 2
Find the equation of g(x)
we have the points
(-2,-6) and (0,4)
Find the slope m
The function in slope intercept form is equal to
we have
-----> the point (0,4) is the y-intercept
substitute
step 3
Find the value of k
we have
-----> equation A
-----> equation B
----> equation C
substitute equation A and equation C in equation B and solve for k
Actually Welcome to the Concept of the Angles.
Complementary angles are those which add up to get 90° , hence here
1.) 90-80 = 10° , 10 is complement of 80
2.) 90-(-120) = 210 , hence 210° is complement of -120
3.) 90-400 => 360°
4.) 90-95 = -5°
5.) 90-5 => 85°
6.) 90-(-35) = 125°
7.) 90-8 = 72°
all are the complement angles above.
