Answer:

x = 6

Step-by-step explanation:

It's simple.

This is just dilation. Since its a scale factor of 0.25 and you want to find x on the bigger one. Then we know we have to then change it into a fraction, 1/4. Which means that 1.5 is only a fourth of x. So, if you do the math: 1.5*4=6.

Therefore, your answer would be x = 6

Which expressions are equivalent to -56z+28−56z+28minus, 56, z, plus, 28?

bearhunter [10]

Answer:

B) $(-1.4z+0.7)\times 40$

D) $(8z-4)(-7)$

Step-by-step explanation:

Given expression:

$-56z+28$

To find the equivalent expression.

We will evaluate each expression in the given choices to check the equivalence.

A) $\frac{1}{2}(-28x+14)$

Using distribution.

⇒ $\frac{-28z}{2}+\frac{14}{2}$

⇒ $-14z+7$

B) $(-1.4z+0.7)\times 40$

Using distribution.

⇒ $(-1.4z\times 40)+(0.7\times 40)$

⇒ $-56z+28$

C) $(14-7z).(-4)$

Using distribution.

⇒ $(14.(-4))+(-7z.(-4))$

⇒ $-56+28z$

D) $(8z-4)(-7)$

Using distribution.

⇒ $(8z(-7))+(-4(-7))$

⇒ $-56z+28$

E) $-2(-28z-14)$

Using distribution.

⇒ $(-2(-28z))+(-2(-14))$

⇒ $56z+28$

From the choices evaluated, we find that the expressions in choices B and D are equivalent

Could someone explain this to me?

Ilya [14]

This is a simple differentiation problem. Let's start by taking the derivative of both sides (with respect to x):
$5y^4\frac{dy}{dx}+6y^2x+6x^2y\frac{dy}{dx}+20x^3 = 0$

Simplify:
$\frac{dy}{dx} (5y^4+6x^2y) + 6y^2x+20x^3 = 0$

Solve for dy/dx:
$\frac{dy}{dx} = \frac{-6y^2x-20x^3}{5y^4+6x^2y}$

Now, plug in the given points:
$\frac{dy}{dx} = \frac{-6(2)^2(-1)-20(-1)^3}{5(2)^4+6(-1)^2(2)} = \frac{24+20}{80+12}$

Further simplification gives:
$\frac{dy}{dx}|_{(2,-1)} =\frac{44}{92} = \frac{11}{23}$

So, your answer is 11/23 or B.
