I NEED HELP :_( Which of the following points is in the solution set of y > -x∧2 + 5? (0, 5) (2, 4) (1, 3)

marysya [2.9K]

Answer:

$\huge\boxed{(2;\ 4)}$

Step-by-step explanation:

We have

$y>-x^2+5$

Put the coordinates of the given points and check the inequality:

For (0; 5) → x = 0; y = 5

$5>-0^2+5\\5>0+5\\5>5\qquad\bold{FALSE}$

For (2; 4) → x = 2, y = 4

$4>-2^2+5\\4>-4+5\\4>1\qquad\bold{TRUE}$

For (1; 3) → x = 1, y = 3

$3>1^2+5\\3>1+5\\3>6\qquad\bold{FALSE}$

Suppose you had d dollars in your bank account. You spent $22 but have at least $42 left. How much money did you have initially?

german

1) What left

$\boxed {d-22 \geq 42}$

*Obs: remember that left at least 42 dollars. In other words, the left over is equal or more than 42 dollars.

2) At the beginning

$d-22 \geq 42 \\ \\ \boxed {d \geq 64}$
