Answer: Option D

Step-by-step explanation:

The equation of the line in slope intercept form is:

y=mx+b

Where m is the slope and b the y-intercept.

Solve for y from both equations:

5y=-3x+9\\y=\frac{-3}{5}x+\frac{9}{5}

5y=-3x+15\\y=\frac{-3}{5}x+3

As you can see, the slopes of the lines are equal, therefore, they are parallel.

If the lines are parallel then the system of equtions has no solution.

Answer:

Choice D  is correct answer.

Step-by-step explanation:

We have given a system of equations.

3x + 5y = 9                             eq(1)

3x + 5y = 15                          eq(2)

We have to find the description of the solution of equations.

y = mx+c is the slope-intercept of equation of line where m is slope and c is y-intercept.

Eq(1) can be written as:

y = -3/5x + 3 where slope is -3/5.

Eq(2) can be written as:

y = -3/5x+5 where slope is -3/5.

Equations with equal slopes are of parallel lines and parallel lines have no solution.Hence, system has no solutions.

Choice D  is correct answer.

Good Stuff is giving away free pens to each of the first 200 people who come in the store today. In the first hour, they gave aw
AnnyKZ [126]

Answer:

50 pens

Step-by-step explanation:

x= 25 percent of 200

25/100 times X/200

Cross multiply them and you get

100x=5000

X=5000/100

X=50

25 percent of 200 is 50.

Which means they have away 50 pens

Which function has the smallest minimum? (5 points)
Andrej [43]
f(x) has the smallest minimum. The minimum value of f(x) is -3

The largest sin(x) can get is 1.
This applies to sin(2x-pi) as well. So f(x) is as small as -5*(1)+2 = -5+2 = -3.
You can see this each time the red curve bottoms out at y = -3.

The smallest that g(x) can get is y = -2 as shown at the vertex (3,-2)

The smallest that h(x) can get is y = 3 as shown by the point (1,3)

See the attachment for a visual comparison of the three functions.
