Is ( 0,0) a solution to this system? y<=x^2-4 y>2x-1?
Xelga [282]

Answer:

The point (0,0) is not a solution of the system of inequalities

Step-by-step explanation:

we have

y\leq x^{2} -4 -----> inequality A

y> 2x-1 -----> inequality B

we know that

If a ordered pair is a solution of the system of inequalities

then

the ordered pair must be satisfy the inequalities of the system

Verify

For x=0, y=0

substitute the value of x and the value of y in the inequalkity A and in the inequality B

Inequality A

0\leq 0^{2} -4

0\leq -4 -------> is not true

therefore

The point (0,0) is not a solution of the system of inequalities

A ladder is leaning against a building so that the distance from the ground to the top of the ladder is 22 feetfeet less than th
ivann1987 [24]
So basically the ladder is creating a right triangle with the ground and the wall. Ladder is the hypotenuse (h), building = b, ground = g
b = h - 22 ft
g = 1010 ft
use Pythagorean Theorem to determine the length of h:
{c}^{2}  =  {a}^{2}  + {b}^{2}  \\  {h}^{2}  =  {(h - 22)}^{2}  + {1010}^{2}  \\ {h}^{2}  =  {h}^{2} - 44h + 484 + 1020100
The h^2 terms cancel out to = 0
0 = - 44h + 484 + 1020100 \\ 44h = 1020584 \\ 44h \div 44 = 1020584 \div 44 \\ h = 23195.1 \: feet
