Find f(-2) for f(x) = 5.3*.

Mathematics

Serga [27]3 years ago
4 0

Answer: 5 * 1/81 = 5/9 or 0.55555

Step-by-step explanation:

You put -2 in for x

I don't know whether it is times x or to the power of x so I will do both

5 * 3 * x

5 * 3 * -2 = -30

------------------------------------------------------------------------------------------------------

5 * 3^x

5 * 3^-2

5 * 1/81 = 5/9 or 0.55555

What are the two plot lines for this
Lyrx [107]

Answer:

You can plot the lines by putting the values of x and y.

For y=x-2, if we put x= 2, then we got y=0

So, the point for this equation will be (2,0). Similarly, you can get many points for the equations and join them to plot lines in the graph.

Mrs. Simmons gave a history test worth 92 points. There were only two types of questions on it: 2-point true/false questions and
SVETLANKA909090 [29]

Answer:

There are 8 true/false questions and 26  fill-in-the-blank questions.

Step-by-step explanation:

Let "t" be the number of 2-point true/false questions and "f" the number of 5-point fill-in-the-blank questions.

Mrs. Simmons gave a history test worth 92 points. Symbollically,

2 t + 5 f = 92   [1]

There were a total of 34 questions in the test. Symbollicaly,

t + f = 34

t = 34 - f   [2]

If we replace [2] in 1, we get

2 (34 - f) + 5 f = 92

68 - 2 f + 5 f = 92

3 f = 24

f = 8

We replace f = 8 in [2],

t = 34 - 8 = 26

There are 8 true/false questions and 26  fill-in-the-blank questions.
