Explain why the expression 7•3x is not equal to the expression 21x

Mathematics
1 answer:
Firdavs [7]3 years ago
5 0
Working out the expression 7(3ˣ) is first to calculate the value of 3ˣ then multiply the answer to 7.

For example, let x = 2
Then 7(3ˣ) = 7(3²) = 7 × 9 = 63

With the same value of x = 2, calculating 21ˣ = 21² = 441, which isn't the same answer with the expression 7(3ˣ)

HELP ASAP!!
Alona [7]

Answer:

The answer is C) - |x - 2| + 3 = 0

Step-by-step explanation:

a) - |x - 2| + 3 > 0

The greater than means something above the graph.

b) - |x - 2| + 3 < 0

The less than means something below the graph.

c) - |x - 2| + 3 = 0

The zero doesn't do anything.

y = - a |x - h| + k = 0

(h,k) is the origin.

h is shift left/right, h = 2 so shift right 2.

k is shift up/down, k = 3 so shift up 3.

The a, affects the y-values which cause the graph to reflect across the x-axis.
