What is the constant of variation if y varies inversely as x and y = 3 when x = 6? PLZ HELP ME I DONT UNDERSTAND

(Y/4) +3 = 7

Subtract 3 from both sides:

Y/4 = 4

Multiply both sides by 4

Y = 16

Answer:

Option D

Step-by-step explanation:

=> (y/4)+3 = 7

Subtracting 3 from both sides

=> y/4 = 7-3

=> y/4 = 4

Multiplying 4 to both sides

=> y = 4*4

=> y = 16

Answer:

Answer D.

Step-by-step explanation:

Rotate the triangle, so that x1 line becomes base. So, the measure of base will be y2-y1. To find the perpendicular height from the base, subtract x1 from x3. Then put the results in area of triangle formula.

Answer:

  [tex]\dfrac{78y}{18y}[/tex]

Step-by-step explanation:

Multiplying by 1 is the same as multiplying by a fraction with the same numerator and denominator.

  [tex]\dfrac{13}{3}=\dfrac{13}{3}\times\dfrac{6y}{6y}=\boxed{\dfrac{78y}{18y}}[/tex]

Answer:

Option 3.

Step-by-step explanation:

Angle E and angle A are corresponding angles, therefore they are congruent angles. Corresponding angles have the same angle.

Answer:

Let h(x) = y

y = 4^(x+3) -2

For x intercept let y = 0

2 = 4^(x+3)

2= 2^2(x+3)

1 = 2x +6

2x = -5

2x = -5

Divide by 2

x = -5/2

The x intercept for the function is ( -5/2, 0)

Hope this helps.

Answer:

(-2.5,0)

Step-by-step explanation:

[tex]h(x)=4^{x+3}-2[/tex]

Since the x intercept of a graph is when the y value is 0:

[tex]0=4^{x+3}-2 \\\\2=4^{x+3} \\\\2=(2^2)^{x+3} \\\\2^1=2^{2x+6} \\\\1=2x+6 \\\\2x=-5 \\\\x=-2.5[/tex]

Answer:

Shortest side = 39 cm.

Median side = 65 cm.

Longest side = 91 cm.

Step-by-step explanation:

The perimeter in total is 195 cm. The ratio of the sides are 3 : 5 : 7.

First, find how much parts there are as a whole, by combining the ratios:

3 + 5 + 7 = 15 parts.

Divide the total of parts from the total measurement:

195/15 = 13

Each part has the measurement of 13 cm.

1 part = 13 cm.

Use the following ratio to solve for each of the sides:

Shortest side: 3

3 x 13 = 39

Shortest side = 39 cm.

Median side: 5

5 x 13 = 65

Median side = 65 cm.

Longest side: 7

7 x 13 = 91

Longest side = 91 cm.

Check. Combine all side measurements together. They should equal 195:

39 + 65 + 91 = 195

(39 + 65) + 91 = 195

(104) + 91 = 195

195 = 195 (True).

Step-by-step explanation:

Given, parallelogram ABCD  intersect at E.

If the parallelogram has to be a rhombus,diagonals should bisect at 90 degree.

So,angle BEA=90degree

Answer:

Option B

Step-by-step explanation:

For this we'll put all of these options in place of x

Number 1:

=> [tex]2(2)^2+7(2)-4[/tex]

=> 2(4)+14-4

=> 8+10

=> 18

So, This is not the zero of the polynomial

Number 2:

=> [tex]2(1/2)^2+7(1/2)-4[/tex]

=> 2(1/4)+7/2-4

=> 1/2+7/2-4

=> [tex]\frac{1+7-8}{2}[/tex]

=> [tex]\frac{8-8}{2}[/tex]

=> 0

Yes, This is the zero of the polynomial having zero as an answer

So, We'll end the solution here because we have found the zero of the polynomial.

3rd term = 13

4th term = 16

10th term = 34

[tex]b)4n - 5 \\ \\ n = 1 \\ 4 \times 1 - 5 \\ 4 - 5 \\ = - 1 \\ \\ n = 2 \\ 4 \times 2 - 5 \\ 8 - 5 \\ = 3 \\ \\ n = 3 \\ 4 \times 3 - 5 \\ 12 - 5 \\ = 7 \\ \\ n = 4 \\ 4 \times 4 - 5 \\ 16- 5 \\ = 11 \\ \\ n = 10 \\ 4 \times 10 - 5 \\ 40 - 5 \\ = 35[/tex]

In this sequence,

1st term = -1

2nd term = 3

3rd term = 7

4th term = 11

10th term =35

Answer:

m∠A 60°, m∠B= 120°, m∠C =60°, m∠D=120°

Step-by-step explanation:

[tex] In\: ||^{gm} \: ABCD, \: BK\perp AD... (given) \\

\therefore \angle BKA = 90\degree \\

In\:\triangle BKA, \\\\

\cos \angle A = \frac{AK}{AB}\\\\

\cos \angle A = \frac{3}{6}\\\\

\cos \angle A = \frac{1}{2}\\\\

\cos \angle A = \cos 60\degree.. (\because \cos 60\degree = \frac{1}{2}) \\\\

\huge \red {\boxed {\therefore \angle A = 60\degree}} \\[/tex]

Since, adjacent angles of a parallelogram are Supplementary.

[tex] \therefore \angle A + \angle B = 180\degree \\

\therefore 60\degree + \angle B = 180\degree \\

\therefore \angle B = 180\degree - 60\degree\\

\huge \purple {\boxed {\therefore \angle B = 120\degree}} \\[/tex]

Since, opposite angles of a parallelogram are congruent.

[tex] \therefore \angle C = \angle A

\\

\huge \red{\boxed {\therefore \angle C = 60\degree}} \\\\

\therefore \angle D = \angle B

\\
