Which graph represents a function with direct variation?

Answer:

No

Step-by-step explanation:

3rd option should be changed to "will not".

9514 1404 393

Answer:

Step-by-step explanation:

Whether the offered numbers will satisfy the inequality is more easily seen by solving it for x.

  6 + 3x ≤ 15

  3x ≤ 9 . . . . . . . . . subtract 6 from both sides

  x ≤ 3 . . . . . . . . . . divide by 3

This is "x is less than or equal to three."

  2 is less than 3 so will meet Mari's goal

  3 is equal to 3, so will meet Mari's goal

  4 is not less than or equal to 3, so will not meet Mari's goal

Answer:

Step-by-step explanation:

What you wrote below the top line and the bottom line are not the same thing.

I think you really want the second line, but one can't be sure.

(1*2 + 5)/2 div (9/8)

7/2 // 9/8

7/2 * 8*9

7*8/18 = 56/18 = 28/9

If you really do want the top line (the latex) it is different.

1 2/5  div (8/9)     Is there such a thing as tfrac? I didn't know this but there is.

(1*5 + 2)5 // (8/9)

7/5 // 8/9             Invert the bottom fraction and multiply

7/5 * 9 / 8

63 / 40

1 23/40

Answer:

Step-by-step explanation:

1.6/x=3/8

do cross multiplication

x*3=6*8

x=48/3

x=16

2.b/8=3/4

do cross multiplication

b*4=8*3

b=24/4

b=6

4.n/8=35/7

do cross multiplication

35*8=7*n

280=7n

280/7=n

40=n

Answer:

Use the referent of an adult stride (about 1 yard) to measure the dimensions of the area that will be covered by sod. Use the dimensions to calculate the area in square yards.

Step-by-step explanation:

This seems to be a relatively vague question, but it was requested so I'll try my best.

There's practically no way to accurately measure the area to be covered by sod without using a reference. I couldn't help but notice the list of references above the question, and I presume they are correlated. Since the length of an adult stride is 1 yard, you can use an adult stride as a reference to relatively accurately measure the dimensions of the area that needs to be covered. The method to find the area varies with the shape of the area, but assuming you can accurately find the area, this is a plausible way to estimate the area needed to be covered by sod. As an alternative, since the question stipulates sod can only be purchased in square yards or square meters, you can use a doorway (about 2 meters) in the list of references above the question to also measure the dimensions of the area. This is less practical because an adult stride is more mobile than a door.

OR  

3

4

Step-by-step explanation:

first you work out what is in the brackets

that is  

1

3

÷

1

6

to give you 2 as you answer

second step rewrite the whole question replacing two in the place of  

1

3

÷

1

6

so you will have  

3

4

+

2

−

(

−

1

2

)

thirdly open the brackets with the negative sign outside the bracket that is:  

−

(

−

1

2

)

so that you get  

+

1

2

(or  

1

2

, basically)

lastly rewrite the whole question

so you will have  

3

4

+

2

+

you can keep that solution, or you can change it from improper fraction to a mixed number

if you use long division,

with a remainder of

doing this by calculator you get 3.25, which is basically

Step-by-step explanation:

tan is the same thing as sin/cos. therefore,

[tex]tan(-\frac{\pi}{2})=\frac{sin(-\frac{\pi}{2}) }{cos(-\frac{\pi}{2}) }[/tex]

[tex]sin(-\frac{\pi}{2})=-1[/tex] and [tex]cos(-\frac{\pi}{2})=0[/tex] so

[tex]tan(-\frac{\pi}{2})=-\frac{1}{0}[/tex] which is undefined. On the graph, this is represented by an asymptote. So your answer is true.

Step-by-step explanation:

Circle A is located at (6, 5) and has a radius of 4 units. What is the equation of a line that is tangent to circle A from point C (2, 8)?

x = 2

y = −0.75x + 9.5

y = 1.33x + 1.66

x = 8

Answer:-28

Step-by-step explanation:

Let A is the second number

the first number is 10.

The total is -18

=> 10 + A =-18 <=> A=-18-10=-28
