Two mechanics worked on a car. The first mechanic worked for 5

ArbitrLikvidat [17]

Answer:

$50 and $115

Step-by-step explanation:

We know that,

the sum of the two rates = $165 per hour

Let x and (165 - x) represent the $/hour of the 15hr and 5hr mechanics respectively.

Then combining their charges together to get:

$(x*15)hour+(165-x)*5 hour=1325$

Solving for x to get:

$15x-5x+825=1325$

$10x=500$

$x=50$

So the rate charged per hour by one mechanic is $50 and for the other mechanic = $(165-50)=$ $115.

What are all of the x-intercepts of the continuous function in the table? (0, 8) (–4, 0) (–4, 0), (4, 0) (–4, 0), (0, 8), (4, an

crimeas [40]

Answer:

The x-intercepts of the continuous function in the table are:

(-4,0) and (4,0).

Step-by-step explanation:

We are given a table of values of the continuous functions as:

(0, 8) (–4, 0) (–4, 0), (4, 0)

The x-intercept of a function is a point on the x-axis i.e. where y=0. (i.e. The x-intercept is where a line crosses the x-axis ).

Here y=f(x).

Hence from the given set of values we have:

f(x)=0 when x= -4 and x=4.

Since we are given the points as (-4,0) and (4,0).

Hence, the x-intercepts of the function f(x) is: (-4,0) and (4,0).
