A washer and dryer cost $793 combined, the washer costs $93 more than the dryer. What is the cost of the dryer?
frosja888 [35]
The dryer costs x.
The washer costs $93 more than the dryer, so it costs x+93.
The washer and the dryer cost $793 altogether.

x+x+93=793 \\&#10;2x=793-93 \\&#10;2x=700 \\&#10;x=\frac{700}{2} \\&#10;x=350

The cost of the dryer is $350.

What appears to be the range of the part of the exponential function graphed on the grid?
Natali [406]

The domain of a function is the set of x values for which it is defined. The range of the given graph will be -2≤x<7.

<h3>What is the domain and range of a function?</h3>

The domain of a function is the set of x values for which it is defined, whereas the range is the set of y values for which it is defined.

As it can be seen that the value on the y-axis is defined for every value of x between -2 to 7, also the value of x  is also defined for x=-2.

Hence, the range of the given graph will be -2≤x<7.
