Answer:
A. f(x)=9x+4
Step-by-step explanation:
Function is f(x) =9x+4, because if x=1, then f(1)=9*1+4=9+4=13;
if x=5,then f(5)=9*5+4=45+4=49
The answer is c to your problemo
X/7 + 9 = 3
a number: x
a number divided by 7: x/7
sum of number divided by 7 and 9: x/7 + 9 (and means plus)
equals 3: x/7 + 9 = 3
The answer is clearly b makes the most sense
The answer is for 1st question is “10.4” and for the second question “non of these choices are correct”.
Explanation:
For the 1st question:
tan = opposite / adjacent
tan 30 = x / 18
18 tan 30 = x
x = 10.4
For the 2nd question,
If a triangle as an angle of 90 degree, it is 100% a right triangle.
Hope it helps :), mark me brainliest please!
