Answer:

x = -143/81

Step-by-step explanation:

Given that:

9\sqrt{x + 3} - 3 = 7

By simplifying:

9\sqrt{x + 3} = 7 + 3\\ 9\sqrt{x + 3} = 10\\

Dividing both sides by 9 we get:

\sqrt{x + 3} = 10/9\\

Squaring both sides we get:

x + 3 = 100/81

Subtracting 3 from both sides we get:

x = 100/81 - 3

x = 100 - 243/ 81

x = -143/81

i hope it will help you!

The two short sides of a triangle are 3 and 4 inches. what is the length of the hypotenuse,in inches?​
disa [49]

Answer:

The length of the hypotenuse is 5 inches.

Step-by-step explanation:

The formula for finding the hypotenuse is a^{2} + b^{2} = c^{2},

with a and be being the two shorter sides of the triangle, while c is the hypotenuse.

Let's plug in our values for a and b and solve.

4^{2} + 3^{2} = c^{2}

16 + 9 = c^{2}

25 = c^{2}

What is the square root of 25? 5.

The length of the hypotenuse is 5 inches.

Which answer choice states the range of the following
ankoles [38]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you forgot to write the relation so I could help you providing my own relation.

Remember that for any relation, we have a set A that matches the the domain (also called the set of inputs) of the function and the set B that contains the range (also called the set of outputs).

Suppose our relation is:

y=-10+x \\ \\ For \ x=1,2,3,4,5

So the x-values represents the set A and the y-values the set B. Therefore, by evaluating the x-values into our relation we get:

\text{If x=1} \\ \\ y=-10+1=-9 \\ \\ \\ \text{If x=2} \\ \\ y=-10+2=-8 \\ \\ \\ \text{If x=3} \\ \\ y=-10+3=-7 \\ \\ \\ \text{If x=4} \\ \\ y=-10+4=-6 \\ \\ \\ \text{If x=5} \\ \\ y=-10+5=-5

So in this context, the correct option is:

B) (-9,-8, -7, -6, -5}

Answer:

im not sure what is supposed to go into the first two boxes, but the correct y intercept is 48

Step-by-step explanation:

first you subtract 288x on both sides, leaving the equation at -4y= -288x-192. then you want to get y by itself so you divide both sides by -4. -288/-4=72; -192/4=48. so the equation you are left with is y= 72x+48. since the equation is now in slope intercept form, you can now identify the y intercept as 48. hope this helps :)
