Y = -128

explanation.
x= -12
y= -200 - 6(x)

-200 - 6(-12)

6(-12) = -72

y= (-200) - (-72)

so, y = -128

Answer:

-128

Step-by-step explanation:

When it says that x = a number, it means you just need to plug in that number for x in the equation. So in this case, we'd plug in -12 and get:

y = -200-6(-12)

Simplify. According to PEMDAS, we do multiplication first. If a number is in parentheses, you multiply it by the number in front of (to the left) of it. In this case, we multiply -6 x -12 and get:

y= -200+72

Add, and our final answer is:

y=-128

Hopefully this helped, and if I was correct, I'd appreciate it if you marked me as the Brainliest :)

If ln(4x+y)=2x-3,then dy/dx=
Viktor [21]

\ln(4x+y)=2x-3

Differentiate both sides wrt x:

\dfrac{\mathrm d(\ln(4x+y))}{\mathrm dx}=\dfrac{\mathrm d(2x-3)}{\mathrm dx}

By the chain rule, we get

\dfrac1{4x+y}\dfrac{\mathrm d(4x+y)}{\mathrm dx}=2

\dfrac{4+\frac{\mathrm dy}{\mathrm dx}}{4x+y}=2

Solve for \frac{\mathrm dy}{\mathrm dx}:

4+\dfrac{\mathrm dy}{\mathrm dx}=8x+2y

\boxed{\dfrac{\mathrm dy}{\mathrm dx}=8x+2y-4}

Help me solve this please -22-x=5+6x+9
ollegr [7]

Answer: x = -5  1/7

Step-by-step explanation:

-22 - x = 5 + 6x + 9

First, combine the like terms 5 and 9

5 + 9 = 14

-22 - x = 14 + 6x

Add x to each side

-22 = 14 + 7x

Subtract 14 from each side

-36 = 7x

Divide each side by 7

x = -5 1/7 (Yes, a fraction.)

What is the product of (–0.9)(–2.4)?<br> –3.3<br> –2.16<br> 2.16<br> 3.3
saul85 [17]
The answer would be 2.16.

This is because the two negatives would cancel each other out when multiplying. This would basically make the question 0.9*2.4.
Now 3.3 is definitely not less than 2.4, so the answer would be 2.16
