Someone please help me.

Let's go:


\frac{80}{2x + 80} = \frac{60}{87} \\\\ 60.(2x + 80) = 80.87 \\\ 120x + 4800 = 6960 \\\ 120x = 6960 - 4800 \\\ 120x = 2160 \\\ x = 18


I hope I helped you.

Write an equation of the line passing through the point (-8, -4) that is perpendicular to the line given by y= 1/6 x+3.
user100 [1]

Answer:

y+4=-6(x+8)  point-slope form

y=-6x-52 slope-intercept form

6x+y=-52 standard form

Step-by-step explanation:

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

Lines that are perpendicular have opposite reciprocal slopes.

So the slope of y=(1/6)x+3 is 1/6.

The opposite reciprocal of (1/6) is -6.

So the equation for the line we are looking for is in the form:

y=-6x+b         (Since the slope of our new line is -6)

Now we want our line to go through (-8,-4).

So plug that in:

-4=-6(-8)+b

-4=48+b

Subtract 48 on both sides:

-52=b

The equation for the line we are looking for is

y=-6x-52.

Now you could do other forms.

Another one is point-slope form.

We already know it goes through (-8,-4) and a slope of -6.

Point slope form is: y-y1=m(x-x1) where m is the slope and (x1,y1) is a point on the line.

Plug in the information to get:

y-(-4)=-6(x-(-8))

y+4=-6(x+8)

I'm going to do one more form.

Standard form is ax+by=c where a,b,c are integers.

y=-6x-52

Add 6x on both sides:

6x+y=-52

If y varies directly as x and y = 35 when x = 5, find y when x = 11.
Sloan [31]

Answer: 77

<u>Step-by-step explanation:</u>

varies directly means: \frac{y}{x} = k

Step 1: solve for k  ⇒  \frac{y}{x} = k   ⇒   7 = k

Step 2: input the given value and the k-value to find the unknown value:  \frac{y}{11} = 7

y = 11(7)

y = 77
