When something increases or decreases by a percentage over time, it's an exponential function, not a quadratic function.
Is that the top or bottom? Assuming it's the top, when distributing the -2 to what's inside the parenthesis, they were correct in multiplying -2•7, but when they multiplied -2 and -y, the answer needs to be positive 2y because they are multiplying double negatives
First one is denominator, then opposite of denominator.. i would wait for someone else to answer. but i’m pretty sure that’s correct. sorry if it is incorrect.. good luck on the rest of your assessment!!
4. D does NOT form a proportion
5. To get the answer you would multiply 45*8=360 then 360/18=20 so n=20
6. same as number 2
multiply 1.2*.6= .72 then .72/1.6= .45 so w=.45
Answer:
Option B will be the correct one.
Step-by-step explanation:
The factor of a polynomial, y = f(x) is obtained by making f(c) = 0 and then solving the equation f(c) = 0 for c and then from the obtained value of c we say (x - c) is a factor of the polynomial y = f(x).
Now, on the reverse, the term (x - a) will be a factor of a polynomial, y = f(x), if and only if f(a) = 0.
Therefore, option B will be the correct one. (Answer)
