Answer:

x^2 -2x -35 = 0

Step-by-step explanation:

Lets's solve backwards

x = -5

Add 5 to both sides

x + 5 = 5 - 5

x + 5  = 0

and

x = 7

Subtract 7 from both sides

x - 7 = 7 - 7

x - 7 = 0

Finding the product of both linear functions

(x + 5)(x - 7) =0

x^2 -7x + 5x -35 =0

x^2 -2x -35 = 0

Use the function rule to complete the table -10x+y=4
Blizzard [7]
-10x+y=4

u just need to plug in values of x in function to get y values
x=-2

-10(-2)+y=4
20+y=4
y=-16

-10x+y=4
x=-1
-10(-1)+y=4
10+y=4
y=-6

-10x+y=4
 at x=0
-10(0)+y=4
y=4
u are getting y values according to x values

y=-16 at x=-2
y=-6 at x= -1
y=4 at x=0

next u can find

a ball is thrown into the air with an upward velocity of 36 ft/s. it’s height h in feet after t seconds is given by the function
lukranit [14]

Complete the square:

h(t)=-16t^2+36t+9=-16\left(t^2-\dfrac94t\right)+9=-16\left(\left(t-\dfrac98\right)^2-\dfrac{81}{64}\right)+9

h(t)=-16\left(t-\dfrac98\right)^2+\dfrac{117}4

That is, the graph of h(t) is a parabola with vertex at (t,h(t))=\left(\dfrac98,\dfrac{117}4\right), meaning the ball reaches its maximum height of \dfrac{117}4=29.25\,\mathrm{ft} after t=\dfrac98=1.125\,\mathrm s of being thrown.
