Answer:
21 because there is a 1/4 chance and there are 84 questions, so 1/4 (25%) of 84 is 21.
Step-by-step explanation:
Negative. It’s the only one that makes since. ( probably)
Xz+y+1=z. given
y+1=z-xz. subtraction property of equality
y+1=z(1-x) distributive property of multiplication over addition/factoring
(1+y)/(1-x) = z division property of required, given x≠1
Well we would need to see some type of graph in order to help you find the slope.
Answer:
10x^3 - 2x^2 -7
Step-by-step explanation:
To subtract polynomials, you want to subtract the biggest exponent from the first polynomial to the second
so 6x^3 + 4x^3 and that would be 10x^3
then -3x^2 + x^2 and the negative is larger so it would be -2x^2
and finally -2 + -5 and that is -7
hope this helps! :)
