The slope of the graph of a direct variation function is 4. What is the equation of the function?

Answer: Choice A) -8 , -5 , 0 , 2 , 6

I recommend drawing out a number line. The negative numbers will increase in magnitude as you move from 0 and go to the left. The positive values increase as you expect when going from left to right.

So we'll have -8 to the left of -5 since -8 is smaller than -5. The value -8 is 8 spots to the left of 0; while -5 is 5 spots to the left of 0. The value 0 is at the center of the number line universe so to speak.

Answer:

Pythagorean Theorem : a²+b²=c²

a²+38²=42² => a²=1764+1444 => a²=3,208 inch => a=√3,208

=> a=56.64 inch

Step-by-step explanation:

we have

6x+7y=4x+4y

we figure out that

the solution is ----> (x,-4)

substitute the value of y=-4 in the equation

6x+7*(-4)=4x+4*(-4)

6x-28=4x-16

Combine like terms

6x-4x=28-16

2x=12

x=12/2

x=6

So the the missing value is x=6.

The estimated cost to attend this college for 1 semester is $9114

3974+400+3240+1500=9114

Nola would have to pay for 8 semesters if she attends for 4 years.

4x2=8

The estimated cost for Nola to attend this college for 4 years is $72912

9114x8=72912

Answer:

3(x+2)

-(2-x)

(3x-2)

Step-by-step explanation:

3x+6= 3(x+2)

       = 3x+6

x-2= -(-x+2)

   =  x -2

15x-10 /  5 =  5(3x-2)/ 5

Answer:

169 students

Step-by-step explanation:

From the above question:

Total number of students surveyed = 260

Percentage of students that their favorite colour is red = 65%

Hence: The number of students that their favorite color is red is calculated as:

= 65% × 260

= 65/100 × 260 students

= 169 students

The number of students that their favorite color is red is 169 students

Answer:

13 years

Step-by-step explanation:

First we will have to see how much she owns her aunt:

800-448= 362

8% of 348 = 27.84

362 ÷ 27.84 = 13 years

I might be wrong but hopefully this helps :)

Answer:

The maximum area possible is 648 squared meters.

Step-by-step explanation:

Let the length of the existing wall be [tex]\ell[/tex].

And let the width of the fence be [tex]w[/tex].

The area of the enclosure will be given by:

[tex]A=w\ell[/tex]

Since the area is bounded by one existing wall, the perimeter (the 72 meters of fencing material) will only be:

[tex]72=2w+\ell[/tex]

We want to maximize the area.

From the perimeter, we can subtract 2w from both sides to obtain:

[tex]\ell=72-2w[/tex]

Substituting this for our area formula, we acquire:

[tex]A=w(72-2w)[/tex]

This is now a quadratic. Recall that the maximum value of a quadratic always occurs at its vertex.

We can distribute:

[tex]A=-2w^2+72w[/tex]

Find the vertex of the quadratic. Using the vertex formula, we acquire that:

[tex]\displaystyle w=-\frac{b}{2a}=-\frac{(72)}{2(-2)}=18[/tex]

So, the maximum area is:

[tex]A=-2(18)^2+72(18)=648\text{ meters}^2[/tex]

Answer:

$15

Step-by-step explanation:

100 divided by 20 = 5, so you do $3 times 5 and you get $15.

The answer would be 80. why? just basically add the x number by it's self and you get your answer.

like 5 +5 gets u 10 in the y axis

and 40+40 gets u 80 in the y axis.

Step-by-step explanation:

Answer:

a) x⩽ -4

Step-by-step explanation:

This is because the required region is anything to the left of -4 that is x < -4. Now since x = -4 is inclusive, we have the inequality x ≤ -4.

We thus draw a dashed boundary line to represent the equality at the boundary for x ≤ -4.

Since that is done, we then shade to the left of the boundary line which is the required region of x ≤ -4.
