Answer:

x = 62

Step-by-step explanation:

x and 118 form a linear pair (added up, they both equal 180 degrees)

Write an expression to find the total cost of buying b paperback books and m magazines if magazines cost $4.95 each and paperbac

xxTIMURxx [149]

Answer:

$Total\ cost=7.95b+4.95m$

Step-by-step explanation:

Paperback Books:

Number of books $=b$

Cost of 1 book $=\$7.95$

$Cost\ of\ all\ paperback\ books=cost\ of\ 1\ book\times number\ of\ books\\\\Cost\ of\ all\ paperback\ book=7.95\times b=7.95b$

Magazines:

Number of magazines $=m$

Cost of 1 magazine= $\$4.95$

$Cost\ of\ all\ magazine=cost\ of\ 1\ magazine\times number\ of\ magazine\\\\Cost\ of\ all\ magazines=4.95\times m=4.95m$

$Total\ Cost=Cost\ of\ paperback\ books+Cost\ of\ magazine\\Total\ Cost=7.95b+4.95m$

The range of the function shown on the graph (see attachment) is: D. -9 ≤ y ≤ 8.

<h3>What is a range?</h3>

A range can be defined as the set of all real numbers that connects with the elements of a domain. This ultimately implies that, a range refers to the set of all possible output numerical values, which are shown on the y-axis of a graph.

<h3>How to identify the range of this graph?</h3>

The vertical extent of a graph represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.

By critically observing the graph shown in the image attached below, we can reasonably infer and logically deduce the following:

Range = [-9, 8]

In interval notation, the range of this graph can be rewritten as -9 ≤ y ≤ 8.

Ryan found that the amount of plant food remaining decreased an equal amount each day, and he used the entire 72 milliliters by

BaLLatris [955]

Answer:

A function rule for the relationship between the amount of plant food remaining, f(x), and the number of days that have passed, x is $f(x)=72-12x$

Step-by-step explanation:

We are given that Ryan used 72 mL of food over the course of a 6 day study.

So, He used amount per day = $\frac{72}{6}$

He used amount per day =12 ml/day

Now we are given that t the amount of plant food remaining decreased an equal amount each day, and he used the entire 72 milliliters by the end of his study.

So, The equation becomes : f(x)=72-12x

f(x):The amount of plant food remaining

x : The number of days that have passed

Hence a function rule for the relationship between the amount of plant food remaining, f(x), and the number of days that have passed, x is $f(x)=72-12x$
