Answer:

Work shown below!

Step-by-step explanation:

h(x) = -50x + 450

This is a linear function because it is the form y = mx + b

Graph 2 and scenario A and Table 3

g(x) = 4^x

It is a growth in the graph because the slope is positive

Graph 1 and scenario C and Table 1

f(x) = -16x^2 + 1900

It is a decay in the graph because the slope is negative

Graph 3 and scenario B and Table 2

Answer:

  a) graph 2, table 3

  b) graph 3, table 2

  c) graph 1, table 1

Step-by-step explanation:

a) "At a constant rate" means any graph and table will be a linear function. Only graph 2 is a straight line (linear). Only table 3 matches graph 2.

__

b) As the wrench drops, its height will be decreasing. Only graph 3 is a decreasing function (of the two remaining). Only table 2 matches graph 3.

__

c) Table 1 and graph 1 are the only remaining choices. Happily, they match each other and the scenario.

_____

<em>Additional comment</em>

You can match the tables to the graphs simply by looking at the y-value for x=0.

If the equation below is solved by graphing, which statement is true? log (6 x + 10) = log 1/2 x
kicyunya [14]

The solution to the given expression is x = -20/11

<h3>
What are logarithmic functions?</h3>

Logarithmic function are inverse of exponential functions. Given the equation below;

log (6 x + 10) = log 1/2 x

In order to determine the solution to the given logarithmic equation, we will first have to cancel the logarithm on both sides to have

6x + 10 = 1/2x

Collect the like terms

6x - 1/2x = 0 - 10

Find the LCD

12x-x/2 = -10
11x/2 = -10

Cross multiply

11x = -2 * 10

11x = -20

Divide both sides by 11

11x/11 = -20/11

x = -20/11

Hence the solution to the given expression is x = -20/11

Divide 5 3/4 ÷ 1 1/2
Kipish [7]

The required mixed number is 3\frac{5}{6} . The calculations are attached with the solution as an image.

What is a mixed number ?

  • A bit represented with its quotient and remainder is a mixed bit. For illustration,21/3 is a mixed bit, where 2 is the quotient, 1 is the remainder.
  • So, a mixed bit is a combination of a whole number and a proper bit. A mixed bit, also called a mixed number, is a whole number and a bit together.
  • The bit is written to the right of the whole number.
  • A mixed number is formed by combining three corridor a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper bit that makes the mixed number.

The required mixed number is 3\frac{5}{6} . The calculations are attached with the solution as an image.
