Step-by-step explanation: When you are asked to solve an inequality like the one in this problem, your goal is the same as it is when solving equations which is to get <em>x</em> by itself on one side.

In this problem, since <em>x</em> is being multiplied by 3 on the left side of the inequality, to get <em>x</em> by itself, we divide both sides by 3.

On the left side, the 3's cancel and we're left with <em>x</em>. On the right side, 12 divided by 3 is 4 so we have X > 4.

This means that A would be or answer.

I picked 40 apples. Katie said she would like to buy 2/3 of them. How many apples did Katie get?
irina [24]

Answer:

26.6666667 Apples

Step-by-step explanation:

Since 40/3 = 13.3 repeating, 13.3 repeating is 1/3 of the apples. Katie wants 2/3, so multiply 13.3 repeating by 2, to get 26.6 repeating

you may need to round up (27) or down (26) depending on your teachers instructions

Is the system of equations consistent, consistent and coincident, or inconsistent? y=3x+4y=3x+3 Select the correct answer from t
Genrish500 [490]

Answer: Inconsistent

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

y = 3x + 4   → m = 3, b = 4

y = 3x + 3   → m = 3, b = 3

These equations have the same slope but different y-intercepts so they are parallel lines <em>which means they will never intersect.</em>

NOTES

  • one solution: consistent & independent        <em>lines cross</em>
  • infinite solutions: consistent & dependent     <em>same line</em>
  • no solution: inconsistent                                  <em>parallel lines</em>

Help please !!! ❗️❗️❗️❗️❗️❗️
Crazy boy [7]

Step-by-step explanation:

1. f(x) = 12x + 1

f(-2) = 12(-2) + 1 = -23

f(0) = 12(0) + 1 = 1

f(3) = 12(3) + 1 = 37

2. p(x) = -8x - 2

p(-2) = -8(-2) - 2 = 14

p(0) = -8(0) - 2 = -2

p(3) = -8(3) - 2 = -26

3. m(x) = -6.5x

m(-2) = -6.5(-2) = 13

m(0) = -6.5(0) = 0

m(3) = -6.5(3) = -19.5

4. s(x) = ⅖x + 3

s(-2) = ⅖(-2) + 3 = -⅘ + 3 = 11/5

s(0) = ⅖(0) + 3 = 3

s(3) = ⅖(3) + 3 = 6/5 + 3 = 21/5

5. h(x) = ¾x - 6

h(-2) = ¾(-2) - 6 = -6/4 - 6 = -30/4

h(0) = ¾(0) - 6 = -6

h(3) = ¾(3) - 6 = 9/4 - 6 = -15/4

Write the equation of a line parallel to the line y = 2x that passes through -2,-1
maksim [4K]

Answer:

y = 2x + 3

Step-by-step explanation:

A line parallel to y = 2x has exactly the same slope but a different y-intercept, b.

Start with y = mx + b, and replace m with 2, y with -1 and x with -2:

-1 = 2(-2) + b, or

-1 = -4 + b.

Then b = 3, and the desired equation is y = 2x + 3
