Answer:

graph B

Step-by-step explanation:

Given

3y - 5x < - 6

Since the inequality is < then the line must be broken

If ≤ then line would be solid

The only possible graphs are B and D

Choose a test point in the shaded region of each graph and check validity

graph B (2, 0) ← substitute into left side of inequality

0 - 5(2) = 0 - 10 = - 10 < - 6 ← this is valid

graph D (0, 0 ) ← substitute into left side of inequality

0 - 0 = 0 > - 6 ← this is not valid

Hence graph B is the correct graph

Answer: $(\frac{\sqrt{3} }{2} ,-\frac{1}{2} )$

Step-by-step explanation:

this forms a 30 degree reference angle

and this is in the 4th quadrant

When the angle is 30 degrees, the coordinates are:

$(\frac{\sqrt{3} }{2} ,-\frac{1}{2} )$

alexi’s restaurant bill is $58, and he wants to leave a 20 percent tip. which expression represents the total amount that alexi

Alexeev081 [22]

He is leaving 20% tip of the bill of $58

20% extra

So total amount = 100% + 20% = 120%

120% of 58

(120/100) * 58

1.2 * 58

= 69.6

So total amount Alexi needs to pay = $69.60

Charlie was carrying around the steps to solve Square root of 6x plus 4 = 8. On his way through the Math Factory, Charlie droppe

Answer: Order will be F,D,C and Fourth Option is correct and x = 10

Step-by-step explanation:

Since we have given that

$\sqrt{6x+4}=8$

We first transpose the square root to the right , so it becomes square of 8,i.e.

$6x+4=8^2\\\\6x+4=64$

Now, transpose 4 to the right so it will get subtract from 64 i.e.

$6x=64-4\\\\6x=60$

Since 6 is multiplied to x on tranposing it will get divided by 60 i.e.

$x=\frac{60}{6}\\\\x=10$

Hence, on simplification, we get x=10.

Hence , the order is F,D,C.
