If –y + 2x^2 – x = -5y^3 then find dy / dx in terms of x and y.

Answer:

12x + 4z

Step-by-step explanation:

Given: 2/3 (18x + 6z)

Multiply the fraction 2/3 into each term

([tex]\frac{2}{3}[/tex])*18x + ([tex]\frac{2}{3}[/tex])*6z

[tex]\frac{36}{3}[/tex]x + [tex]\frac{12}{3}[/tex]z

12x + 4z

Answer:

-1/11

Step-by-step explanation:

[tex]\frac{11x}{12} -\frac{1}{6} =\frac{-1}{4}[/tex]    add 1/6 to both sides

[tex]\frac{11x}{12} =\frac{1}{6} -\frac{1}{4}[/tex]  make the same denominator 12 on the right side

[tex]\frac{11x}{12} =\frac{1}{6}*\frac{2}{2} -\frac{1}{4}*\frac{3}{3}[/tex]  solve

[tex]\frac{11x}{12} =\frac{2}{12} -\frac{3}{12} =\frac{2-3}{12} = \frac{-1}{12}[/tex]

[tex]\frac{11x}{12}*12 =\frac{-1}{12} *12[/tex] multiply by 12 both sides

11x= -1 divide by 11

x= -1/11

Answer:

Slope = -2, y-intercept = 12 (b)

Step-by-step explanation:

Using the slope formula:

slope = change in y (y2-y1) / change in x (x2-x1)

slope = (12-18)/(0+3)

slope = -6/3

slope = -2

The slope is -2

If you look in the table, when x=0, the y value equals 12. This means that the y-intercept = 12, since the y-intercept is when the x equals 0. Thus we have our answer.

Answer:

Yes I believe

Step-by-step explanation:

Answer:

1) Slope is 2/1 and the y-intercept is 2 --> y = 2x+ 2

2) Slope is -1/3 and the y-intercept is -3 --> y = -1/3x -3

Answer:

Step-by-step explanation:

Greater, provided the divisor is positive.

It would be more accurate and clearer to say that when dividing a number which is greater than zero by a number between 0 and 1, then the quotient is greater than the dividend.

If the divisor is negative and the dividend is positive, then the quotient is negative (and hence less than the dividend).

Answer:

3. x = 5

4. -5 1/25

Step-by-step explanation:

-3x+5=-10

Subtract the 5 from both sides...

-3x = -15

Divide by -3

x = 5

For 4, it's just multiplying.

-2 4/5 in improper form is -14/5

1 4/5 in improper form is 9/5

-14/5 x 9/5 is -126/25

-126/25 can be -5.04 or -5 1/25.

Answer:

3. a (x=5)

4. -126/25

Step-by-step explanation:

3. -3x+5=-10

-3x=-10-5

-3x=-15

x=5

4.  -(-2 4/5) x 1 4/5

(-14/5) x 9/5

= -126/25

Answer: is A because they are equal

Answer:

b = 2.666.......

Step-by-step explanation:

[tex]-\frac{3}{4} b = 2[/tex]

------    -----

[tex]-\frac{3}{4}[/tex]      [tex]-\frac{3}{4}[/tex]

b = 2.666.....

Answer:

Step-by-step explanation:

If point A is between P and R, then;

PA+AR = PR

Given

PA=3x-4,

PR=21 meters,

AR=7 meters

Substitute

3x-4 +7 = 21

3x+3 = 21

3x = 21-3

3x =18

x =18/3

x = 6

Hence the value of x is 6m

Answer:

Because we actually divide by 10 when a number is multiplied by 0.1.

Step-by-step explanation:

Let [tex]a[/tex] be a number.

When we multiply a number by 10:

[tex]a \times 10 = 10 a[/tex] (One '0' is increased in the number)

For example:

[tex]23 \times 10 = 230[/tex]

Considering a decimal number:

[tex]2.3 \times 10 = 23[/tex]

Multiplying a number with 0.1 (which is actually [tex]\frac{1}{10}[/tex]) means dividing the number by 10.

[tex]23\times 0.1 =23\times \frac{1}{10}=2.3[/tex]

Considering a decimal number:

[tex]2.3 \times 0.1 = 2.3 \times \frac{1}{10} = 0.23[/tex]

Therefore, When multiplying a number by 0.1, move the decimal to the left.

Answer:

Sample Response: You move the decimal to the right when multiplying a number by 10 because you are making the number bigger. You move the decimal to the left when multiplying a number by 0.1 because you are making the number smaller.

Step-by-step explanation:

Answer: 180, 45

Step-by-step explanation:

First, you look at the patterns for each numbers, so you can apply the rules for the next two sequences

720 divided by 180 = 4

360 divided by 180 = 2

360 divided by 90 = 4

for the next sequences, you multiply the last number by 2 (90 x 2 =180)

then divide the answer by 4 to get the answer (180 divided by 4 = 45)

so the next two numbers are 180, 45

Answer:

19 inches and 60 inches

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equations

[tex]y=-6x-10[/tex]

[tex]y=-3x-21[/tex]

solving the system of the equations

Arrange the equation variables for elimination

[tex]\begin{bmatrix}y+6x=-10\\ y+3x=-21\end{bmatrix}[/tex]

[tex]y+3x=-21[/tex]

[tex]-[/tex]

[tex]\underline{y+6x=-10}[/tex]

[tex]-3x=-11[/tex]

[tex]\begin{bmatrix}y+6x=-10\\ -3x=-11\end{bmatrix}[/tex]

solve

[tex]-3x=-11[/tex]

Divide both sides by -3

[tex]\frac{-3x}{-3}=\frac{-11}{-3}[/tex]

[tex]x=\frac{11}{3}[/tex]

[tex]\mathrm{For\:}y+6x=-10\mathrm{\:plug\:in\:}x=\frac{11}{3}[/tex]

[tex]y+6\cdot \frac{11}{3}=-10[/tex]

[tex]y+6\cdot \frac{11}{3}=-10[/tex]

[tex]y=-32[/tex]

Therefore, the solutions to the system of the equations are:

[tex]y=-32,\:x=\frac{11}{3}[/tex]

But, it seems none of the options is true.
