4.b.

Answer: See below.

Step-by-step explanation:

<h2><u>For the equation f(x) = 2x</u></h2>

3.a. f(6) means use x = 6 in the equation f(x) = 2x

so f(6) would be f(6)= 2(6)

<u>f(6) = 12</u>

3.b. f(-11) = 2(-11)

<u>f(-11) = -22</u>

3.c. f(2.75) = 2(2.75)

<u>f(2.75) = 5.5</u>

3.d. This is turned around. We are told f(x)=20, so what would x need to be for f(x) to be 20? Since f(x) = 2x, we can say 20 = 2x. Therefore x = 10

f(10) = 20

<u>The rest of (3) are solved in the same fasion.h</u>

<u></u>

<h2><u>For the equation f(x)= 5x+50</u></h2>

4.a. f(7) = 5(7)+50

<u>f(7) = 85</u>

4.b. f(-12)

f(-12) = 5*(-12)+50

<u>f(-12) = -60</u>

<u></u>

Continue in the same fashion for these types of problems.

What is the opposite <br> of -5/3

ss7ja [257]

Answer:

5/3

Step-by-step explanation:

The opposite of a number always has to have the same distance from zero, positive or negative. So in this case, since -5/3 is a negative fraction, the answer would be 5/3. This fraction may be positive but they have the same distance from zero.

Pls help I can't do anything I will give the brain thingy

Sidana [21]

Step-by-step explanation:

<u>Blank</u><u> </u><u>C</u> :

Given total = 68

No. of TV news = 13

Therefore, in Internet it would be = Total - TV news

= 68 - 13 = <u>55 (ans)</u>

<u>Blank</u><u> </u><u>D</u> :

No. of Internet news in 7th grade = 55

No. of Internet news in 8th grade = 64

Hence, total Internet base news = 64 + 55 = <u>119 (ans)</u>

<u>Blank</u><u> </u><u>B</u> :

All total = 138

Internet news total = 119

Hence, TV news total = All total - Internet news

= 138 - 119 = <u>19 (ans)</u>

<u>Blank</u><u> </u><u>A</u> :

No. of TV news in 7th grade = 13

Total news in TV = 19

Therefore, no. of TV news in 8th grade = 19 - 13 = <u>6(ans)</u>

<u>Blank</u><u> </u><u>E</u> :

All total = 138

Total of 7th grade news = 68

Hence, total of 8th grade news = 138 - 68

= <u>70 (ans)</u>

Which transformation moves all points the same distance in the same direction?

Lesechka [4]

Answer:

In a translation, ALL of the points move the same distance in the same direction. A translation is called a rigid transformation or isometry because the image is the same size and shape as the pre-image.
