there are 350 students in the 7th grade class in 1/5 of them play sports. how how many students play sports?

larisa86 [58]

Answer:

Step-by-step explanation:

so divide 350 into 5 groups, which equals 70.

70*5 is 350, so we didn't make a mistake.

It says 1/5, so the answer is 70.

If it was 2/5, we do 70*2 which equals 140.

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y <

shepuryov [24]

Answer:

See explanation

Step-by-step explanation:

You have to graph the system of inequalities presented as

$\left\{\begin{array}{l}y$

Part A:

1. Draw a dotted line $y=4x-2$ (dotted because the sign < is without notion "or equal to"). Select one of two regions by substituting the coordinates of origin into inequality:

$0$

Since this inequlity is false, the origin doesn't belong to the shaded region, so you have to shade that part which doesn't contain origin (red part in attached diagram).

2. Draw a solid line $y=-\frac{5}{2}x-2$ (solid because the sign ≥ is with notion "or equal to"). Select one of two regions by substituting the coordinates of origin into inequality:

$0\ge -\frac{5}{2}\cdot 0-2\\ \\0\ge -2$

Since this inequlity is true, the origin belongs to the shaded region, so you have to shade that part which contains origin (blue part in attached diagram).

The intersection of these two regions is the solution area.

Part B:

Plot point (-2,-2). Since this point doesn't belong to the solution area, this is not a solution of the system of two inequalities. You can check it mathematically - substitute x=-2 and y=-2 into the system:

$\left\{\begin{array}{l}-2$

Both inequalities are false, so (-2,-2) doesn't belong to the solution area.

Which is the graph of y= cos(x-pi)

marshall27 [118]

Answer:

graph attached

Step-by-step explanation:

A graph is a pictorial representation that represent the relationship between two or more things.

Cosine function is periodic with period $2\pi$ . If the point $(x,y)$ lies on the graph, point $(x+2k\pi ,y)$ will also lie on the graph where k is any integer.
