Answer:

x=-7/2, y=1

Step-by-step explanation:

y=-2x-6

y=x+9

I'm going to use elimination.

2y=2x+9

y=-2x-6

3y=3

y=1

Enter y into one of the equations to find x.

2=2x+9

2x=-9+2

2x=-7

x=-7/2

PLEASE HELp PLEASE
bagirrra123 [75]

Answer:

Part A. For x, we’ll use 1, 2, 3, 4, and 5. Now, we have to plug in the x-values to get f(x) (or y). I’ll do the first two w/ explanations then just give the answers. when x= 1, f(1)= 2/3•1-1. solve accordingly, you get -0.3. Next, when x= 2, f(2)= 2/3•2-1. Solve and you get f(2)= 0.3. when completing and solving for the other 3 x-values, use the same process and plug into the chart with corresponding numbers. A calculator may be helpful.

Part B. Just graph, use the x-values for x and the y-values for y. if u don’t know how to graph u may want to look back on some of your lessons if available.

Thanks.

2. Function C takes time for its input and gives a student's Monday class for its output.
kaheart [24]

Answer:

We know that C(T) is a function where you input the time T, and the output will be the student's Monday class.

a) A student has English at 10:00.

Here we can use T = 10:00 as the input, and the output will be the class, English.

Then this can represent this with:

C(10:00) = English.

b) Write a statement to describe the meaning of C(11:15) = chemistry.

for C(11:15) = Chemistry

The input, the time, is 11:15

The output, the class, is chemistry.

The student has a chemistry class at 11:15
