Drag the tiles to the correct boxes to complete the pairs Match each inequality to the number line that represents its solution

Anna [14]

Answer:

x ≤ 7 => $- \frac{13x}{18}$ + $\frac{5}{9} \geq - \frac{9}{2}$

x ≤ 8 => - $\frac{x}{10}$ + $\frac{1}{5}$ ≥ - $\frac{33}{55}$

x ≤ -5 => - $\frac{50x}{3}$ - $\frac{11}{6}$ $\geq$ $\frac{163}{2}$

x ≤ -6 => $\frac{3x}{2}$ + 105 ≤ 96

Step-by-step explanation:

- $\frac{x}{10}$ + $\frac{1}{5}$ ≥ - $\frac{33}{55}$

$\frac{1}{5}$ + $\frac{33}{55}$ ≥ $\frac{x}{10}$ / *10

2 + 6 ≥ x

8 ≥ x

- $\frac{50x}{3}$ - $\frac{11}{6}$ $\geq$ $\frac{163}{2}$ / *6

- 100x - 11 ≥ 489

-500 ≥ 100x

-5 ≥ x

$\frac{3x}{2}$ + 105 ≤ 96

$\frac{3x}{2}$ ≤ 96 - 105 / * $\frac{2}{3}$

x ≤ -6

$- \frac{13x}{18}$ + $\frac{5}{9} \geq - \frac{9}{2}$ /*18

-13x + 10 ≥ - 81

-13x ≥ -91 /:-13

x ≥ 7

Graph the line using intercepts: 4x-3y=12

Furkat [3]

First you have to find the intercepts!

To find the y-intercept (I usually do that first), pretend x=0.
Then it becomes:
4(0)-3y=12
Which then becomes:
-3y=12.
Divide both sides, and y = -4.
Then the (x,y) coordinate would become (0, -4).

Next you would find the x-intercept, and pretend y = 0.
Which then becomes:
4x-3(0)=12
3x0 cancels out to become:
4x = 12
And x = 3 because division stuffs.
Then THIS point would then be (3,0).

So then, you would plot (0,-4) and (3,0) on a graph and connect the points! I attached a picture for reference.

hope that helped~
