Find the slope of y=(-8x-3)
Artemon [7]

\tt Step-by-step~explanation:

This equation is in slope-intercept form: y = mx + b, where m is the slope, and b is the y-intercept.

To find the slope of y = - 8 x - 3, we have to find what replaced m. -8 replaced m here, so -8 is the slope of this equation.

F(x) = 3x^2 + 4x - 7<br> g(x) = 5x - 3<br> Find (f +g) (x)
snow_tiger [21]

f(x) = 3x^2 + 4x - 7          g(x) = 5x - 3

(f + g)(x) = f(x) + g(x)\\= (3x^2 + 4x - 7) + (5x - 3)\\= 3x^2 + 4x - 7 + 5x - 3\\= 3x^2 + 9x - 10

What that two numbers when multiplied give 600 and when added give 59 ​
ozzi

Answer:

Step-by-step explanation:

Let the 2 numbers be x and y

From the problem we have that

x * y = 600 and x + y = 59

From x + y = 59 -> x = 59 - y

Plug x = 59 - y to x * y = 600 we have

(59 - y) * y = 600

-> 59y - y^2 = 600

-> -y^2 + 59y - 600 = 0

-> y = (59 - \sqrt{1081})/2 or (59 + \sqrt{1081})/2

Then we could plug the answers in and find x because x = 59 - y

We want to find the zeros of this polynomial: p(x) = (x - 1)(x + 3) * (2x + 1) Plot all the zeros (-intercepts) of the polynomia
Alekssandra [29.7K]

Answer:

Step-by-step explanation:

Because the function is a product, the zeros will occur when any term is equal to zero. For

(x-1)(x+3)(2x+1) the value will be zero when x=1,-3, or -1/2 so the points are

(-3,0), (-1/2,0), and (1,0)
