Can anyone help me with this?<br>complete the table of values of <br>f(x) = 3×​
n200080 [17]

Answer:

See sample table below.

Step-by-step explanation:

The function is given as :

f(x) = 3ˣ

A table of values can be formed as ;

x                <u>calculations</u>           f(x)

-4               3⁻⁴                          0.0123

-3               3⁻³                          0.0370

-2               3⁻²                          0.1111

-1                3⁻¹                           0.3333

0                 3⁰                            1.000

1                  3¹                             3.000

2                 3²                             9.000

3                 3³                              27.00

9) Solve by the elimination method.<br><br> x + y = -5<br> x - y = 11
vlabodo [156]
<h2><u>Answer:</u></h2>

x = 3

y = -8

<h2><u>Step-by-step explanation:</u></h2>

x + y = -5

x - y = 11

Since the y's will cancel out, we don't need to modify the two equations in any way.

Now, just add the two equations.

x + x = 2x

y + (-y) = 0

-5 + 11 = 6

2x = 6

Divide by 2.

x = 3

To find y, plug 3 in as "x" in one of the two equations.

3 + y = -5

y = -8
