Evaluate when a =3 b= 4.5 and h = 6

lys-0071 [83]3 years ago
6 0

Answer:

For Example:  Evaluate a2b for a = –2, b = 3, c = –4, and d = 4.

Step-by-step explanation:

To find my answer, I just plug in the given values, being careful to use parentheses, particularly around the "minus" signs. Especially when I'm just starting out, drawing the parentheses first may be helpful:

a2 b

(    )2 (  )

(–2)2 (3)

(4)(3)

12

Note how using parentheses helped me keep track of the "minus" sign on the value of a. This was important, because I might otherwise have squared only the 2, ending up with –4, which would have been wrong.

By the way, it turned out that we didn't need the values for the variables c and d. When you're given a big set of expressions to evaluate, you should expect that there will often be one or another of the variables that won't be included in any particular exercise in the set.

Evaluate a – cd for a = –2, b = 3, c = –4, and d = 4.

In this exercise, they've given me extra information. There is no b in the expression they want me to evaluate, so I can ignore this value in my working:

(–2) – (–4)(4)

–2 – (–16)

–2 + 16

16 – 2

14

I need help on understanding this concept
Sedbober [7]
So the slope formula is m= (y2-y1) /
(x2-x1). You can label -2 as x1 and 11 as y1. And the other point is x2 and y2. They you just plug it in the m= (y2-y1) /
(x2-x1) formula and solve. To get a better understanding look up, how to find the slope of a line with two points. Hope it helps
