(-4, -2), (-2, -1), (0, 0), (2, 1), (4, 2)

This is line passing through the origin and the equation is:

f(x) = 1/2x

Rate of change is the slope 1/2, which is same over any interval

Which exponential equation is equivalent to this logarithmic equation log x5 + log x12 =7

trapecia [35]

Answer:

x⁷ = 60

Step-by-step explanation:

Given :-

log x⁵ + log x ¹² = 7 .

To Find :-

The expotential equation .

Solution :-

Given logarithmic equation is ,

⇒ log x⁵ + log x ¹² = 7

⇒ log x ⁵ * ¹² = 7 [ log aⁿ + log aⁿ' = log aⁿ * ⁿ' ]

⇒log x ⁶⁰ = 7

In expotential form we can write it as ,

⇒ x⁷ = 60

What are the solutions of x^2+10x+21=0?

Luden [163]

(x+7)(x+3) so therefore you set each equation = 0...
x + 7 = 0
x + 3= 0
and solve
x = -3
x = -7

I need help on this one.

Flura [38]

Answer:

1) 180 is a straight line, so 180 - 118 = 62

2) 180 degrees are in a triangle, so 180 - (62) - 73 = 45

3) 180 is a straight line, so 180 - 73 = 107. There are 180 degrees in a triangle, so 180 - 49 - 45 = 86
