Answer:

James needs to earn 78 more dollars.

Step-by-step explanation:

Does (5, 10)make the inequality y ≥ 10x+5 true

Salsk061 [2.6K]

Answer:

It is False.

Step-by-step explanation:

When you substitute the coordinates into the inequality equation :

$y \geqslant 10x + 5$

$let \: x = 5,y = 10$

$10 \geqslant 10(5) + 5$

$10 \geqslant 55 \: (false)$

Therefore, 10 isn't greater than 55.

State the amplitude and period of f(x)= -3 sin t

Sphinxa [80]

Answer:

The period is $2\pi$ and the amplitude is 3.

Step-by-step explanation:

The period goes from one peak to the next (or from any point to the next matching point). The amplitude is the height from the center line to the peak.

The period of the function $y=a\sin (bx)$ is $T=\dfrac{2\pi }{b}$ and the amplitude is $|a|.$
