Slope= $\frac{ y_{2}- y_{1} }{ x_{2} - x_{1} }$

(3,5) and (1,9)
x1=3
y1=5
x2=1
y2=9

Slope= $\frac{ y_{2}- y_{1} }{ x_{2} - x_{1} }$
Slope= $\frac{ 9- 5 }{ 1 - 3}$
Slope= $\frac{4}{ -2}$
Slope= $-\frac{4}{2} or -2$

Answer:Slope=-2

If the probability of an outcome is 2/9, what are the odds against that outcome?

IrinaVladis [17]

Answer:

7/9

Step-by-step explanation:

If the chances of an outcome are 2/9, the odds against it can be found by subtracting that from 1.

1 - 2/9

= 7/9

So, the odds against that outcome are 7/9

Yupin is making fruit punch. The recipe calls for 2 ½ of guava juice. The guava juice container has 4 ¼ cups of juice in it. How

astraxan [27]

Answer:

1 $\frac{3}{4}$ cups

Step-by-step explanation:

Convert the numbers to decimals, then subtract the amount needed from the amount in the juice container:

4.25 - 2.5

= 1.75

This is equivalent to the fraction 1 $\frac{3}{4}$

So, after Yupin makes the punch, there will be 1 $\frac{3}{4}$ cups of guava juice left in the container

Answer:

14 nickels
6 dimes

Step-by-step explanation:

The system of equations can be written ...

n + d = 20 . . . . . . . . coins in the jar

5n +10d = 130 . . . . . value in cents

_____

Using the first equation, we can write an expression for n:

n = 20 -d

We can substitute this into the second equation:

5(20 -d) +10d = 130

100 +5d = 130 . . . . . . simplify

5d = 30 . . . . . . . . . . . . subtract 100

d = 6 . . . . . . . . . . . . divide by 5

n = 20-d = 14

The jar contains 14 nickels and 6 dimes.

How do you solve this step by step?

Sphinxa [80]

Answer:

x = 41

Step-by-step explanation:

To solve this problem, we want to find the value of 'x' by isolating it (separating 'x' from all other numbers).

First, simplify the expression by using the <u>distributive property</u>, where you multiply the number outside the brackets with each term inside the brackets.

Then isolate 'x' by doing reverse operations (on both sides) for every number that is on the same side as 'x'. Reverse operations are opposites (addition and subtraction, multiplication and division) and "cancel out" a number, which "moves" it to the other side.

7(x - 5) = 252 Use the distributive property

7x - 35 = 252 Result of 7 times x and 7 times -5

7x - 35 + 35 = 252 + 35 Add 35 to both sides

7x = 252 + 35 -35+35 on the left side cancelled out. Simplify right side

7x = 287 Continue to isolate 'x'

7x/7 = 287/7 Divide both sides by 7

x = 287/7 Left side cancelled out to be 'x'. Simplify the right side

x = 41 Answer

Check your answer:

Substitute 'x' for 41 in the original equation. Then, make sure that the equation is still balanced. Keep in mind BEDMAS order (brackets, exponents, division, multiplication, addition, subtraction).

7(x - 5) = 252

7(41 - 5) = 252 Simplify inside the brackets first

7(36) = 252 Multiply

252 = 252 Same answer

LS = RS

Since left side (LS) equals (=) right side (RS), the equation is still balanced and we got the correct value for 'x'.
