A because he only teaches one thing calculus
Answer:
x= -6
v= 1
v= 2
Step-by-step explanation:
-3= x+7-4, combine like terms by subtracting seven from four
-3= x+3, subtract three from both sides
-6= x
8v-3+3v= 8, combine like terms by adding 8v and 3v
11v-3= 8, add three to both sides
11v= 11, divide both sides by 11
v=1
-v+3v=4, combine like terms by adding -v and -3v
2v= 4, divide both sides by 2
v= 2
Answer:
B
Step-by-step explanation:
table B: because when x increases y increases at the same rate and stay the same . the graph has proportional relation when it is a straight line passes through origin
for B :25/20=30/24=40/32=5/4
y=5/4 x
