Math Plz Help. <br><br>Please graph with two points! <br>explain how you found your answer

Softa [21]

X intercept: y = 0
y= -3/4x -4
0 = -3/4 x - 4
4= -3/4 x
4 • -4/3 = x
-5.3 = x
y intercept: x = 0
y = -3/4 x -4
y = -3/4 (0) -4
y = -4
the points are (-5.3, 0) and (0, -4)

Rationalise the denominator.

grin007 [14]

Let's see what to do buddy...

_________________________________

To do this, we have to multiply the face and denominator of the fraction by the denominator conjunction, which is :

$(5 -\sqrt{2})$

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

Reminder :

$(a + b)(a - b) = {a}^{2} - {b}^{2} \\$

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

So we have :

$\frac{1}{ 5-\sqrt{2} } \times \frac{ 5+\sqrt{2} }{ 5 +\sqrt{2} } = \frac{1 \times ( 5 +\sqrt{2}) }{(5- \sqrt{2} )( 5 +\sqrt{2}) } = \\$

The other is in the photo.

And we're done.

Thanks for watching buddy good luck.

A survey was done to determine the effect of students changing answers while taking a multiple-choice test on which there is on

Umnica [9.8K]

Answer:

6% of the changes were from incorrect to incorrect

Step-by-step explanation:

The sum of the percentages must be 100%.

We have these following percentages

65% of the changes were from incorrect answers to correct

29% were from correct to incorrect

P% were from incorrect to incorrect

$65 + 29 + P = 100$

$P = 100 - 94$

$P = 6$

6% of the changes were from incorrect to incorrect
