Answer:

Correct option: c) infinitely many solutions

Step-by-step explanation:

We have an equation with two variables, so as we have a system with less equations (just one) than variables (two), we have an infinite number of solutions.

To find some solutions, we can choose values for x and then just calculate the value of y:

x = 0:

-11y = 10 -> y = -10/11

x = 1:

3 - 11y = 10 -> y = -7/11

x = 2:

6 - 11y = 10 -> y = -4/11

And so on.

So the correct option is c): infinitely many solutions

What is the inverse of the function 9y - 6 = 3x ?

IgorC [24]

Answer:

Option (2)

Step-by-step explanation:

Given function is,

9y - 6 = 3x

y = $\frac{3x+6}{9}$

To find the inverse of the given function,

1). Substitute x in place of y and y in place of x.

x = $\frac{3y+6}{9}$

2). Now we have to solve this equation for the value of y.

9x = 3y + 6

3y = 9x - 6

y = (3x - 2)

Therefore, inverse of the given function is y = (3x - 2)

Option (2) will be the answer.

Please Help! What is the distance between points (2, 8) and (7, 5)? Round to the nearest tenth of a unit.

zavuch27 [327]

Distance formula is like pythagoren ahtoerem
D= $\sqrt{(7-2)^{2}+(5-8)^{2}}$
the distance between oints (x1,y1) and (x2,y2) is
D= $\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}$
(2,8) and (7,5)
D= $\sqrt{(7-2)^{2}+(5-8)^{2}}$
D= $\sqrt{(5)^{2}+(-3)^{2}}$
D= $\sqrt{25+9}$
D= $\sqrt{34}$
apxos
D=5.8309....

round
D=5.8 units

Answer: 4x² -4

Step-by-step explanation:

First, evaluate the exponent you'll get, $3^{0}$ + 4x² -5 then evaluate to get, 1+ 4x² -5. Next, subtract the numbers, 1 + 4x² -5 then to get, -4 +4x². Lastly, rearrange the terms, -4 +4x² turns into, 4x² -4!
