Answer:A)0.75
Step-by-step explanation:
Given
There are four options to a question
out of which one is correct with 4 points
one is wrong but carries 1 point
Other two are wrong with a negative Point
Probability of selecting an option is 
Expected score
Expected score=1+0.25-0.5
Expected score=0.75
the pattern is that you take each number and multiply it by 3
Answer: y=-2x-9
Step-by-step explanation:
Add 4x to both sides because the slope (-2x) needs to be on the same side as the y-intercept (-9). Then divide everything by 2 to get your answer because you want to get y by itself, since there is two of them. 2y-4x=-18 becomes y=-2x-9.
not sure what your asking..don’t think you can identify what “t” is without further explanation!
I can help you only with #2.
Area= l*w
Area=(l+3)*w
Area= 130
Let's try 10 and 13.
Is the length 3 greater than its width? YES
Does it multiply to 130? YES
LENGTH= 13 CM
WIDTH=10 CM
cHECK=
13*10=130
