Answer: (x, y) = (10, 10)

Since x = y, replacing y with x in 6x - 3y = 30 we have 6x - 3x = 3x = 30, so x = 30/3 = 10. Then y = x = 10, so the solution is (10, 10).

i hope this helps! :D

A soccer player uses her head to hit a ball up in the air from a height of 2 meters with an initial vertical velocity of 5 meter

Mandarinka [93]

Answer:1.32 s

Step-by-step explanation:

Given

The initial height of ball H=2 m

Initial velocity u=5 m/s

Height of ball at any instant is given by

$H=-4.9t^2+5t+2$

The ball will hit the ground when h=0

$-4.9t^2+5t+2=0\\4.9t^2-5t-2=0\\t=\dfrac{5\pm\sqrt{25+4(4.9)(2)}}{2\times 4.9}\\t=\dfrac{5\pm\sqrt{64.2}}{9.8}\\t=\dfrac{5+8.01}{9.8}=1.32\ s\quad\text{Neglecting negative value of t}$

Y = – 1.3(x + 3)2 – 9

Naddika [18.5K]

Given equation, y = – 1.3(x + 3)2 – 9 is in slope intercept form.

Step-by-step explanation:

Slope intercept form standard formula:

y = mx + c

where,

y= y intercept

x= x intercept

m = slope

c = constant

We are given:

y = - 1.3(x + 3)2 - 9

y = - 2.6x + 7.8 - 9

y = -2.6x -1.2

So,

Slope = m = -2.6

constant = 1.2
