V = ( 9*2 ) / 3 ;
v = 18 / 3 ;
v = 6 ;
a. is the right answer;

( 119.5 / 151 ) * 100 = 11950 / 151 = 79.1 ;

The percent is 79.1%;

c. is the right answer;


1 - (40/100)*1 = 1 - 2 / 5 = 3 / 5 = 0.60 ;

What is the slope of a perpendicular line 2x + y = 6<br><br> is answer -2
Firdavs [7]

Answer:

The slope that is perpendicular to the line will be:

m_2=+\frac{1}{2}

Step-by-step explanation:

Given the equation

2x\:+\:y\:=\:6\:

We know that

y=mx+b is the slope-intercept form of a line where m is the slope and b is the y-intercept.

So, writing the equation in the slope-intercept form

2x\:+\:y\:=\:6\:

\:y=-2x+6

here

m=-2        ∵  y=mx+b        

As we know that for perpendicular lines, one slope is the negative reciprocal of the other.

Therefore, the slope that is perpendicular to the line will be:

m_2=+\frac{1}{2}

Y = (x + 9)(x-4)<br><br>Now we need to multiply our binomials​
MA_775_DIABLO [31]

Answer:

x^{2}+5x-36

Step-by-step explanation:

To multiply binomials there are 2 ways. F.O.I.L., or the box method.

I will use the box method, and I hope it helps you!

After looking at the picture, this is not the answer quite yet.

x^{2}+9x-4x\\-36

Subtract 4x from 9x.

9x-4x=5x

So, the answer will be x^{2}+5x-36
