Answer:

13

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

   = ( -9-4)/(6-7)

   = -13/-1

  = 13

Answer:

9,7,5,3,1 is the correct fx in the table

Answer: (I trust you can graph the points)

{(6,9), (7, 7), (8, 5), (9, 3), (10, 1)}

Step-by-step explanation:

-2x+21

x=6 -12+21 = 9

x=7 -14+21 =7

x=8 -16+21 = 5

x=9 -18+21=3

x=10 -20+21=1

Answer:

The answer is below:

Step-by-step explanation:

The range is everything under and including 6 as we see that it will forever go to numbers under or equal to 6.

The range is all real because the lines will keep on going to infinity and negative infinity

Domain: All Real

Range: y is greater than or equal to 6

Step-by-step explanation:

r = 32/40 = 0.8

S10 = 40(1- (0.8)^10)/ (1- 0.8)

= 40(1 - 0.107) / 0.2

= 200(1.107)

= 221

It's C, Peanut oil freezes at a lower temperature than olive oil because 3.1 > -6.1

Answer:

A) a = 25

B) b = 14

Step-by-step explanation:

hopefully this helps :)

Solve the following:

[tex] \\ \sf \: a) \: \: \frac{a}{5} + 3 = 8[/tex]

[tex] \\ \sf \: b) \: \: \frac{3b}{7} - 1 = 5[/tex]

Solving question a) :

[tex] \\ \sf \frac{a}{5 } + 3 = 8[/tex]

[tex] \\ \sf \mapsto \frac{a + 15}{5} = 8[/tex]

[tex] \\ \sf \mapsto \: a + 15 = 8 \times 5[/tex]

[tex] \\ \sf \mapsto \: a = 40 - 15[/tex]

[tex] \\ \sf \mapsto \: a = 25[/tex]

[tex] \\ \sf \therefore \: a = 25[/tex]

Solving question b) :

[tex] \\ \sf \frac{3b}{7} - 1 = 5[/tex]

[tex] \\ \sf \mapsto \: \frac{3b - 7}{7} = 5 [/tex]

[tex] \\ \sf \mapsto3b - 7 = 5 \times 7[/tex]

[tex] \\ \sf \mapsto3b = 35 + 7[/tex]

[tex] \\ \sf \mapsto \: b = \frac{42}{3} [/tex]

[tex] \\ \sf \mapsto \: b = 14[/tex]

[tex] \\ \sf \therefore \: b = 14[/tex]

a = 25

b = 14

Explanation:

There are 7 blue marbles out of 4+7+8 = 11+8 = 19 total

The probability of selecting blue is therefore 7/19

We cannot reduce 7/19 any further because 7 and 19 have no common factors other than 1.

Answer:  

D. y = [x] - 2

Explanation:  

The Greatest Integer Function is denoted by y = [x].

     For all real numbers, x, the greatest integer function returns the largest integer less than or equal to x. In essence, it rounds down a real number to the nearest lowest integer.

         In the plot of y = [x], the plot starts from origin because y = [0] = 0.

                      But, in the question, all the lines are shifted 2 units downward, as it starts from (0, -2).

i.e for every values of x, y moves two units down

                               So our answer is y = [x] - 2.

(Information reworded from "InesWalston" who is another user on Brainly when they responded to the same question!)

                             Hope this helps, good luck! :D

[ SIDE NOTE: Someone else said that it is y=[x]-4, so I am not 100% sure! ]

Answer:

3.33333

Step-by-step explanation:

divide the length value by 12

Answer:

16 for the first one. each segment is 4

40 for the second. each segment is 8

Answer:

0, 4, 8, 12, 16

8, 16, 24, 32, 40, 48

Step-by-step explanation:

The first number line has 6 parts. 24÷6=4. Each vertical line will increase by 4.

So starting at 0, the parts of the number line are:

0, 4, 8, 12, 16, 20, 24

The specific part being asked for is 0, 4, 8, 12, 16

The second number line has 8 parts. 64÷8=8. Each vertical line will increase by 8.

Starting at 0, the parts of the number line are:

0, 8, 16, 24, 32, 40, 48, 56, 64

The specific part being asked for is 8, 16, 24, 32, 40, 48

Answer:

5 five dollar and 7 one dollar

Step-by-step explanation:

1x+5y=32

x+y=12

using elimination method

+x-x-y+5y-32+12=0

4y-20=0

4y=20

y=20/4 =5

so, if. y is 5 then x is

5y+x=32

5(5)+x=32

25+x=32

x=32-25

x=7
