1)B -26-27x
steps :distribute ,-9 times 3 =-27 , -9 times 3x = -27x , now combine like terms :you have a 1 and a -27 ,1-27=-26,and you left with -27
2)D 11-49x
steps :distribute , positive 7 times 1= 7 and then positive 7 times negative 7x =-49, now combine like terms ,since you have a positive 4 combine it with positive 7 which is 11 and finally put it together with -49x which it would look like 11-49x
Answer:
x = -10
Step-by-step explanation:
y = 2x + 5
-15 = 2x + 5
-20 = 2x
-10 = x
I'm going to use numbers but is the same thing example:Aa
Answer:
in the graph
Step-by-step explanation:
the function g(t)= sin t is a periodic function with amplitude a0= 1 and period T0=2
For our case, the 5 that multiplies g (t) increases the amplitude so that a = 5 * 1 = 5 and the 3 that multiplies the variable increases the period being T = 2*1/3 = 2/3
