Answer:

The unit rate\frac{4}{1} of the graph is 4, the slope of the graph is 4, and the comparison between answers is that they are equal.

Step-by-step explanation:

For every increase of 1 in the X value of the graph, the Y value increases by 4, so the slope would be \frac{4}{1} or 4.

Solve each radical equation. Be sure to check your solutionsa)√(2x-3)=11b)∛(6-x)=-3
leva [86]

Answer:

a) x = 62

b) x = 33

Step-by-step explanation:

Hi there!

a) Let´s write the equation:

√(2x-3) = 11

Square both sides

2x - 3 = 121

add 3 to both sides of the equation

2x = 124

divide by 2 both sides

x = 62

Let´s check:

√(2x-3) = 11

x = 62

√(2(62)-3) = 11

√(124-3) = 11

√121 = 11

11 = 11

x = 62 satisfies the equation

b) Let´s write the equation:

∛(6 - x) = -3

Cube both sides

6 - x = -27

subtract 6 to both sides

-x = -27 - 6

-x = -33

divide by -1 both sides

x = 33

Now, let´s check the result:

∛(6 - x) = -3

x = 33

∛(6 - 33) = -3

∛(-27) = -3

-3 = -3

x = 33 satisfies the equation

Ramkin is going to flip a fair coin 100 times.
Gelneren [198K]

Answer:

50 times

Step-by-step explanation:

You are going to flip a coin 100 times. There are 2 sides. So, what you would do is divide 100 by two because there are two sides. There is a 50% chance that the coin will land on heads, and a 50% chance it will land on tails.

Please let me know if you have any more questions. Hope this helps!
