Aparabola is represented by the equation y = x2 + 6x − 17. the x-intercepts of the parabola . the y-intercept of the parabola . (if necessary, round your answers to the nearest hundredth.)

2.8, 8.8, and -17 respectively.

Step-by-step explanation:

We need to find roots of the equation.

x-intercepts : ≈

y- intercepts :

Step-by-step explanation:

To find the x-intercept(s), substitute in  0 for y and solve for x.

thus

Using quadratic formula for finding value of x.

                            ±

thus we get,

   x-intercepts :   ≈

Now for y-intercept(s), substitute in 0 for x and solve for y.

thus

we get,

                  y- intercepts :

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

50-38=12
