The answer is 14 - x.
If she is 14 now, and the question is looking for her age x years ago, it is basically just asking you to subtract x from 14.
It also can't be x - 14, because that means Susie's age is x and the question is asking for her age 14 years ago, and it can't be 14x, because that's 14 multiplied by x.
Answer:
Step-by-step explanation:A function defines one variable in terms of another. The statement "y is a function of x" (denoted y = y(x)) means that y varies according to whatever value x takes on. A causal relationship is often implied (i.e. "x causes y"), but does not *necessarily* exist.
Answer:
4r(x)+2t(x)=42x-14
Step-by-step explanation:
4r(x)=32x+4
2t(x)=10x-18
4r(x)+2t(x)=32x+4+10x-18=42x-14
Answer:
(x-1)(x-9)
Step-by-step explanation:
x^2-10x+9
= (x^2-x)+(-9x+9)
= x(x-1)-9(x-1)
= (x-1)(x-9)
Answer:
55
