Liono4ka [1.6K]3 years ago
5 0

Step-by-step explanation:

simplify

log(x)/log(4) = 0

simplify

log(4x)/log(4) = 1

expand

2log(5)/log(4) + log(4x)/log(4) = log(100)/log(4)

factor

2log(5) + log (4x) / log(4) = log (100) / log (4)

then

x=1

A store sells black ink pens for $5 and red ink pens for $4. John wishes to buy 20 pens but doesn’t wish to spend more than $92.
Vlad1618 [11]

Answer:

Step-by-step explanation:

Let b represent the number of black

ink pens that John wants to buy.

Let r represent the number of red

ink pens that John wants to buy.

John wishes to buy 20 pens. This would be expressed as

b + r = 20

The store sells black ink pens for $5 and red ink pens for $4. John doesn’t wish to spend more than $92. The inequality to show this information would be expressed as

5b + 4r ≤ 92

Tina decides to measure how the amount of force (in newtons) that concrete can withstand changes as the surface area over which
maksim [4K]
To know the unit of measurement of the final answer, you have to use the technique of dimensional analysis. In this technique, you strip off the magnitudes of the units to do away with the calculations. You have to make sure first that you end up with the final answer. So, for this problem, you are given two parameters: force and surface area. Thus, you focus on the units of force and surface area. One of the units must be in Newtons to represent the force, and the other should be in square units to represent the area. From the choices given, the answer would most likely be letter B.

This is the other choices include units like cubic units and kilograms which pertain to volume and mass, respectively. None of these have to do with force and surface area.

Softa [21]

Answer:

C. {(2,4) (3,4) (4,4) (5,4) (6,4)} is a function.

Step-by-step explanation:

Since there is one value of  y  for every value of  x  in  {(2,4) (3,4) (4,4) (5,4) (6,4)}, this relation is a function.
