If function g has the factors (x-7) and (x+6) what are the zero of function g

1 answer:

Ilya [14]2 years ago

8 0

Answer:

-6 or 7

Step-by-step explanation:

g(c)=0 if and only if x-c is a factor

since g(x)=(x-7)(x=6) then g (7)=0 and g(-6)=0

since those two x values output 0, then those x values are called the zeros

Solutions: -6 or 7

Two mechanics worked on a car. The first mechanic charged $55 per hour, and the second mechanic charged $60 per hour. The mechan

Nady [450]

Answer:

15 and 5 hours.

Step-by-step explanation:

Call x the time taken by the first chap, and y the second.

$\left \{ {{x+y = 20 \atop {55x+60y=1125}} \right.$

Let's divide by 5 and play with the LHS of the first equation a bit:

$11x+ 11y +y = 225\\11(x+y)+y= 225$ we know how much x+y is ( first equation!) let's solve.

$11(20) +y = 225 \rightarrow y=5$ At this point it's easy to check that $x=15$

What is the equation of a line that is parallel to -x+3y=6 and passes through the point (3,5)?

Elena-2011 [213]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

By definition, if two lines are parallel then their slopes are equal.

We have the following line:

$-x + 3y = 6\\3y = x + 6\\y = \frac {1} {3} x + \frac {6} {3}\\y = \frac {1} {3} x + 2$

Thus, the slope is: $m_ {1} = \frac {1} {3}$

Then $m_ {2} = \frac {1} {3}$

So, the line is of the form:

$y = \frac {1} {3} x + b$

We substitute the point $(x, y) :( 3,5)$ and find b:

$5 = \frac {1} {3} (3) + b\\5 = b$

Thus, the equation is:

$y = \frac {1} {3} x + 5$

Answer:

$y = \frac {1} {3} x + 5$
