If p(x)=x^2+x+1 and q(x)=3x^2-1, find p(7)

Mathematics
1 answer:
Delvig [45]3 years ago
7 0

Answer:

p(7) = 57

Step-by-step explanation:

Because this is a function, all you have to do is input 7 for x like so:

p(x)=x^2+x+1 --------------->     p(7)=7^2+7+1

                                            so 49 + 8

                                                = 57

What is the slope of the line with the coordinates (0,0) and (-4,7).
Citrus2011 [14]

Answer:

Slope = -7/4

Step-by-step explanation:

Let's find the slope between your two points.

(0,0) ; (−4,7)

(x1,y1) = (0,0)

(x2,y2) = (−4,7)

Use the slope formula:

m = y2−y1 / x2−x1

= 7−0/−4−0

=7/−4

= −7/4

Answer:

m= −7/4

Hope this helps!!
