Find the x-coordinates of the points where the graph crosses the x-axis.<br> y = (x - 3)(x + 8)
sleet_krkn [62]

Answer:

The x-coordinates of the points are x = 3 and x = - 8.

Step-by-step explanation:

We have to find the x-coordinates of the points where the graph of equation y = (x - 3)(x + 8) crosses the x-axis.

Now, the x-intercept of a function implies that y = 0 {Because on x-axis, y-value is zero}

Hence, (x - 3)(x + 8) = 0

⇒ (x - 3) = 0 and (x + 8) = 0

⇒ x = 3 and x = - 8

Therefore, the x-coordinates of the points are x = 3 and x = - 8. (Answer)

FinnZ [79.3K]

Answer:

c. -2

Step-by-step explanation:

because the linear line goes down we know it is negative

and its not 1/2 because it is rise over run. it runs 1 and rises 2 (or drops 2 because it is negative)

rise over run = -2/1 = -2

Which best describes the solutions of 8x&lt;-48?
Black_prince [1.1K]

Answer:

i think is b

Step-by-step explanation:

because the equation 8x<-48 means -48 greater than 8x so it if you choose a than i will become 8(6)<-48 this is wrong because positif integer always is greater,zero also greater than negatif integer.So by comparing the another i think the answer is b.I hope it will help you and it is correct.
