There are two zeros: -3 and -1. This is because when you factor f(x)<span>= x^2 + 4x + 3, it becomes f(x) = (x + 3)(x + 1). In order to find the zeros, set f(x) to 0, and then solve for x for both (x + 3) and (x + 1). You can check your answer by substituting either -3 or -1 for x in the equation 0 = </span>x^2 + 4x + 3.

Help me with this question
madreJ [45]

Answer:

  60

Step-by-step explanation:

In the function, the growth factor is "a", the base of the exponent. When the exponent is increased by 1, the value is multiplied by "a".

  f(7) = a·f(6) = 4·15

  f(7) = 60

_____

As you know, the exponent signifies repeated multiplication. So, an increase of 1 in the exponent means the base is part of the product one more time:

  a^6 = a·a·a·a·a·a

  a^7 = a·a·a·a·a·a·a = a·(a^6)

Given the formula y = mx + b, what is the slope of a line, m, if x = 5, y = 7, and b =10?
Alex17521 [72]

y = mx + b

if x = 5, y = 7, and b =10

Plug in

7 = m(5) + 10

-3 = 5m

re-write

5m = -3

 m = -3/5

Answer

slope m = -3/5
