gAnswer:
x represnts the number of t-shirts and y represents the price
x = 1 y = 9
x = 2 y = 16
x = 3 y = 24
etc.
Step-by-step explanation:
This is not propational relationship because if it was putten on a graph it would not make a striaght line. The quantities do not have a propational relationship because for it can be a propational relationship you have to divide or multiply, you have to have a striaght line, and it has to go through the origin (0,0)
Answer:
No. It can be obtuse angle are angles greater than 90° but less than 180°
And for an isosceles triangle, two angles must be equal so if two angles are greater than 90° that mean the sum of angle in a triangle is above 180° which is not possible
Step-by-step explanation:
The answer is 4n-25
4 times n is 4 n
and 25 decreased or subtracted from the 4n
thus the answer is 4n-25
Tan(x)= sin(x)/cos(x), therefore, substitute sin(x)/cos(x) in the expression:
=(cos(x)(sin(x)/cos(x))-1)/cos^2(x)
simplify the 2 cos(x):
=(sin(x)-1)/cos^2(x)
Sin^2(x)+ cos^2(x)=1, sin^2(x)-1=- cos^2(x), substitute in the expression:
= -cos^2(x)/cos^2(x)= -1
Answer: 24
Step-by-step explanation: Multiply 4 by 6 to get 24
