Answer:

Step-by-step explanation:

y=mx+b where m=slope and b=y intercept

m=(y2-y1)/(x2-x1)

m=(-2-4)/(2+1)

m=-2 so far we have the slope

y=-2x+b, using point (2,-2) we can solve for b, the y intercept

-2=-2(2)+b

-2=-4+b

2=b so we have our line

y=-2x+2, slope is -2 and y intercept is 2

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.

Martha measures the big prize wheel on a game show and calculates that it has a circumference of 12.56 yards. What is the prize

trasher [3.6K]

The radius is 2 yards...
Formula for circumference is $\pi r^2$ so divide your circumference by 3.14 or pi and you get 4 the square root of 4 is 2.

Hope this helps!
