Answer:
x = -6
y= 1
Step-by-step explanation:
make one of the variables equal to each other
4(2x+3y) = -9
3(-x+4y) = 10
subtract
8x+12y = -36
- -3x+12y =30
----------------------
11x = -66
x = -6
plug back in to find y
8(-6)+12y = -36
12y= 12
y = 1
Put these in order by the exponents....descending order....so put the highest exponent first
16f^4 + 4f^3 - 9f^2 + 19f....and the 3rd term is : -9f^2
If you mean what's the difference between 4^x and x^4 then
4^x means 4 times itself x times
x^4 means x times itself 4 times or x times x times x times x
A)
Let c be the number of right guesses.
the probability of c answers =.25 and probability of the wrong answer is 1-.25=.75
c distribution is in the parameter of (20, .25).
b) mean = 20 * .25== 5
c) p of c guess =.25 ^20 =9.095* 10 ^-13
d) p of 10 c guess =.014 or 1.4% it is not possible for him to have 10 right guess.
Answer:
3/2
down 6 left 4 (both negative)
since both are negative, you have a positive slope
