Which set of data represents a linear function?

Answer:

Love you too

As a friend :)

Answer:

y = 0.5 at x = 4

Step-by-step explanation:

According to question,

y is inversely proportional to cube of x i.e.

[tex]y\propto \dfrac{1}{x^3}\\\\y=\dfrac{k}{x^3}[/tex]

or

[tex]k=yx^3[/tex]

Put x = 2 and y = 4 in above expression to find k.

[tex]k=4\times (2)^3\\\\=32[/tex]

Now put x = 4 to given equation to find y.

[tex]y=\dfrac{32}{4^3}[/tex]

y = 0.5 or 1/2

So, the value of y is 0.5 when x = 4.

Answer:

A. 7 divided by 2

Step-by-step explanation:

The computation is shown below;

[tex]= 6\frac{3}{4} \div 1 \frac{2}{3} \\\\= \frac{27}{4} \div \frac{5}{3}\\\\= \frac{27}{4} \times \frac{3}{5}\\\\= \frac{27\times 3}{4\times 5} \\\\= \frac{81}{20} \\\\= 4 \frac{1}{20}[/tex]

It could be 4.05

So according to the given options, the option 1 is chosen at is closed to 4.05

Hence, the option A is correct

Answer:

how old is he now...?

Answer:

w=0

Step-by-step explanation:

We know a point (3,1) and the slope (-8/3), so we can use point-slope form, which is y-y1=m(x-x1)

For reference, y1 is the y in the point, m is the slope, and x1 is the x in the point

So we subsitute it

y-1=-8/3(x-3)

do distributive prop.

y-1=-8/3x+8

add 1 to both sides

y=-8/3x+9

This is the equation of the line.

Now to find w, which is the x value.

The point will pass through line, so we can susbtitute the point into the equation.

9=-8/3x+9

subtract 9 from both sides

0=-8/3x

multiply by -3/8 on both sides (the reciprocal of -8/3), we need to isolate x

0=x

x=w

therefore, w=0

Hope this helps!

Answer:

1. 0.25

2. 0.4

3. 0.44

4. 0.79

Step-by-step explanation:

I’m so sorry short on time can’t explain right now

Step-by-step explanation:

For two lines to be parallel they must have the same slope that is,M1=M2

For two lines to be perpendicular the slope of one must be the negative reciprocal of the other

Let's first find the slope of all three lines.

For line 1

6x-6=10y

2/5x-2/5=y

slope=2/5

For like 2

slope=5/3

For line 3

y=5/3x+2/3

We can therefore say that:

line 1 and line2 are neither parallel nor perpendicular

line 1 and line 3:

neither parallel nor perpendicular

line 2and line 3:

parallel lines

Answer:

B. <

Step-by-step explanation:

The whole parts are equal since they are both 9.

We just need to compare the fractions 3/8 and 5/7.

The LCD is 8 * 7 = 56

3/8 = 21/56

5/7 = 40/56

3/8 < 5/7

9 3/8 < 9 5/7

Answer:

C. 1.87

Step-by-step explanation:

3.5x - 2.8 = -4.67x + 12.5

3.5x + 4.67x = 12.5 + 2.5

8.17x = 15.3

x = 15.3 ÷ 8.17

x = 1.87270501836

So, the closest choice to 1.87270501836 is 1.87, so the answer is C.

Hence, the answer would be C. 1.87. I am 100% sure on this, for I am a pro.

Answer:

Angle of Elevation = 38°

Step-by-step explanation:

Angle of Elevation formula is given as

tan x = Opposite /Adjacent

Where

x = Angle of Elevation

Opposite = Height of the tower = 41 meters

Adjacent = Shadow of the vertical tower = 52.5 meters

Hence:

tan x = 41 m/52.5m

x = arc tan (41 m/52.5m)

x = 37.988141726°

Approximately to the nearest degree x = 38°

Answer:

The Temperature at 7PM

Step-by-step explanation:

Answer:

8 grams

Step-by-step explanation:

The balance is in equilibrium, so the weights of the two sides are equal.

Let the weight of a square be s.

Left side: 2s + 4

Right side: s + 3(4) = s + 12

The weights are equal, so we set the two expressions equal.

2s + 4 = s + 12

s = 8

Answer: The weight of a square is 8 grams.

Question 2: The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.

Answer: x=14

only #2

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

2x+6−3x=3x−8−3x

−x+6=−8

Step 2: Subtract 6 from both sides.

−x+6−6=−8−6

−x=−14

Step 3: Divide both sides by -1.

-x/-1=-14/-1
