First, we need to know the slope-intercept equation which is: Y=mx+b.

Where b, equals the y-intercept. Here, the y-intercept is -4, which is where the line touches the y. Next, we have to figure out the "m" in the equation, which is the slope. To figure out the slope, you have to choose 2 points on the graph and see how many "Rise" and "Runs" you have to do to go from one point to another. In this case, the slope is 8/3. So, we have the formula of y= 8/3x+-4

Hope this helps!

M is 20% less than N means

M is 100-20=80% of N

M=0.80 N

M/N = 0.8 = 4/5


Ratio: 4/5


112.


When we know <em>a, </em>the average, and <em>n, </em>how many numbers there are, we know the sum <em>s</em>, because <em>a=s/n </em>so <em>s=na.</em>


So the sum of our six numbers is 6(3.5)=21 so the sum of the seven numbers is 21+4.2=25.2 so the average is 25.2/7 = 3.6


Answer: 3.6


113.


|2p + 4 | < 3


At p=-2 the absolute value is zero. As p gets more negative the absolute value argument (inside part) gets negative and the absolute value gets bigger, more positive. Eventually the inside will be exactly -3, when


2p +4 = -3


2p = -7


p = -7/2 = -3 1/2


So p=-4 will make the inequality false, and p=-3 is the smallest integer that makes the inequality true.


Answer: -3

The distance from the origin is given by the Pythagorean Theorem and this one is a 3/4/5 right triangle:


d = \sqrt{(-.3)^2 + (-.4)^2}=.5

(!!WORD PROBLEM!!)

Answer: a package of cookies cost $ 5 and each bag of chips cost $5

Step-by-step explanation:

Let x represent the cost of a package of  cookies and y represent the cost of a bap of chips ,then from the first statement :

4x + 4y = 40

dividing through by 4 , we have

x + y = 10 ........................... equation 1

From the second statement

3x + 5y = 40  ..................... equation 2

Solving the system of linear equation by substitution method , from equation 1 , make x the subject of the formula , that is

x = 10 - y ................... equation 3

substitute x = 10 - y into equation 2 , we have :

3 (10 - y ) + 5y = 40

30 - 3y + 5y = 40

30 + 2y = 40

subtract 30 from both sides

2y = 40 -30

2y = 10

y = 5

substitute y = 5 into equation 3 , equation 3 becomes

x = 10 - 5

x = 5

Therefore ; a package of cookies cost $ 5 and each bag of chips cost $5

Slope Formula: m= \frac{ y_{2} }{ x_{2} }  -  \frac{ y_{1} }{ x_{1} }

I am going to show you how to do this on problem 6, and you will do the rest of the problems. 

Here are the steps to solving problem 6

Step 1) Substitute the coordinates into the slope formula

\frac{-1-2}{-18-(-8)}

Step 2) Now Lets simplify the denominator, so we don't have two Subtractions symbols.

\frac{-1-2}{-18+8}

Step 3) Simplify

\frac{-1-2}{-18+8} =  \frac{-3}{-10}

Step 4) We can still simplify more

\frac{-3}{-10} =  \frac{3}{10}

Hope This Helps ... Good Luck

[The reason I didn't do all of them is because you need to know how to do them. Trust me later on knowing these is going to be very handy.]

Can someone help me please??? :((

Answer:

25 months

Step-by-step explanation:

when the rent, y = 0, we have,

y = -200.22x + 5014.20

y = 0

0 = -200.22x + 5014.20

200.22x = 5014.20

x = 5014.20 ÷ 200.22

x = 25.0434

x = 25(appx.)

Sorry, I don't know what you mean by interpolation and extrapolation:(
