Answer:

1 4/7

Find a number that will divide evenly into both the top number and the bottom number. (You can do any math operation to either number as long as you do the same to the bottom number.)

Keep doing that until you can't find a number that works.

In this case try 5.

55 ÷ 5 = 11 and 35 ÷ 5 = 7

so: 55/35 = 11/7

since the top number is greater than the bottom, reduce 11/7 to 1 4/7

Find the equation of the line through the point (–2, –2) that is perpendicular to the line y = 2x – 1.

lawyer [7]

Hi student, let me help you out!

.....................................................................................................

---------------------------------------------

Perpendicular lines have slopes that are <u>opposite inverses </u>of each other.

The opposite inverse of 2 is $\mathrm{-\cfrac{1}{2}}$ .

Now let's stick in this number into the equation $\mathrm{y=mx+b}$ :

$\mathrm{y=-\cfrac{1}{2}x+b}$ . Let's carry out several operations to determine the y intercept.

First, let's stick in -2 for x and y (Do you remember that the line passes through (-2,-2)? We're given that piece of information.)

$\mathrm{-2=-\cfrac{1}{2}\times(-2)+b}$ .

You are probably thinking, "Why did you do that and just complicate things?" Wait for it! ^-^

Upon simplifying this, we obtain: $\mathrm{-2=1+b}$ . See, it's nice and smooth now.

One last operation remains. We need to subtract 1 from both sides: $\mathrm{-3=b}$ .

∴, the equation of the line is: $\mathrm{\underline{\boxed{y=-\cfrac{1}{2}-3}}}$

Hope this helped you out, ask in comments if any queries arise.

Best Regards!

What is the degree of each monomial?<br> 7m^6n^5<br><br> a. 5<br> b. 11<br> c. 6<br> d. 7

Alinara [238K]

Why are you still asking these? Just add up the exponents!

$7m^6n^5 \\ 6+5 = \boxed{11}$

It cost $520 to plant 4 acres of corn. How much would it cost to plant 3/5 acre of corn?

VLD [36.1K]

Importance should be given to all the informations that are already given in the question. based on those information's, the answer to the question can be easily determined.
The cost of planting 4 acres of corn = 520 dollars
Then
the cost of planting 1 acre of corn = (520/4) dollars
   = 130 dollars
So
The cost of planting 3/5 acres of corn = (3/5) * 130 dollars
   = 3 * 26 dollars
   = 78 dollars
So the cost of planting 3/5 acre of corn is $78. I hope the procedure is clear enough for you to understand. You can always use this method in future for solving similar type of problems without requiring any help from outside.

Which pairs of points would result in a line with a rate of change of 2:1? Select all that apply.

Helen [10]

Answer:

Options A, C, D are true.

Step-by-step explanation:

We have to choose the pair of points from that given in the attached file which will result in a line with a rate of change i.e. slope of 2:1 i.e. 2.

A. The points are (-4,-11) and (-2,-7).

Then the slope of the joining line is $\frac{-7-(-11)}{-2-(-4)} =2$
