Answer:

Step-by-step explanation:

A quadratic inequality looks like a quadratic equation, but with signs

<, >, ≤, or ≥

instead of sign =

You are given one equation (the first one, because the sign is =) and two inequalities (the last two beacause the signs are < and > respectively).

Thus, correct option is A,

$y=7x^2+5x-7$

is not a quadratic inequality (it is a quadratic equation)

Z=82 vertical or opposite angle theorem
15x-7 + 82=180 supplementary angles theorem
so 15x +75 =180
15x=180-75
x=105/15
x=7

Neporo4naja [7]

The equation of motion is
s(t) = (1/2)a·t² +v₀·t +s₀
where a is the acceleration, v₀ is the initial velocity, and s₀ is the initial position.

For t in seconds and s(t) in feet, your values make this equation be
s(t) = 5t² -20t +8

Answer:

y = 9.8x + 6.7

y = 6.7x + 9.8

y = 7.5x + 3.8

y = 3.8x + 7.5

Step-by-step explanation:

I made 2represent x.

y= 9.8(2) + 6.7

y = 26.3

y=6.7(2) + 9.8

y= 23.2

y= 7.5(2) + 3.8

y= 18.8

y= 3.8(2) + 7.5

y= 15.1
