Answer:

x=1

y=-4

Step-by-step explanation:

Since -x-3=y subsitue that in at the top equation

$- x - 3 = - 7x + 3$

$- x = - 7x + 6$

$6x = 6$

$x = 1$

Plug x=1 back into the equation to solve for y.

$y = - 7(1) + 3$

$y = - 4$

The function f(x) = −x2 − 5x + 50 shows the relationship between the vertical distance of a diver from a pool's surface f(x), in

lisabon 2012 [21]

First of all, the root is $5$ , since

$-5^2-5\cdot 5 + 50 = -25-25+50=0$

Then, since the $x$ represents the horizontal distance, and $f(x)$ the height, we can read $f(5)=0$ as "the height is zero when the diver is $5$ feet away from the board.

So, the answer is D.

1.) What is the vertex of the quadratic function y=x^2-4x-1

Serjik [45]

1. Solve by differentiation (Derivative = 0 at the vertex)

dy/dx= 2x-4

0=2x-4

0=2(x-2)

x=2

when x=2 y=-5

therefore vertex (2,-5)
