Which product is negative?
Nataliya [291]

Answer: -3.4.(-2) • (-2)= -48

Step-by-step explanation: please keep in mind that every number that you multiply by 0 is equal to 0, it does not mind if number is positive or negative the result will be always 0, if we have this clear we can pass with following step.

then you do not need resolve the equation with 0 because you know that result will be 0, after that we get only one equation the first one.

-3 * 4 * (-2) * (-2)

keep in mind when you are multiplying numbers with the same sign the product will be positive, but when you are multiplying numbers with different signs the result will be negative.

we can resolve this value by value for example

-3 * 4 * (-2) * (-2)

-3 * 4= -12

then we get the following equation

-12 * (-2) * (-2)

then we can pass with the next value

-12 * (-2) = 24

then we get the following equation

24 * (-2) = -48

as you can see this will be the only one equation with a negative product.

Which function is nonlinear? Y=4x+9 y=7/x-6 y=x-6/7 15 points
AleksAgata [21]

Answer:

The answer is y = 7/x -6.

Step-by-step explanation:

A linear function is one where x and y are both to the first power.  Using this knowledge, let's look at the options that we are given.

y = 4x + 9

In the above equation, both x and y are raised to the first power, so we know that this equation is linear.

y = 7/x - 6

In the above equation, y is raised to the first power, but x is not.  Since x is in the denominator of a fraction, it actually has a power of -1, which makes this equation nonlinear.

y = x - 6/7

In the above equation, both x and y are raised to the first power, making the equation linear.

Therefore, the correct choice is y =7/x - 6.

Hope this helps!

Georgia [21]

Answer:

D) x = √5

Step-by-step explanation:

\sqrt{x^{2}+4 }-1 = 2

\sqrt{x^{2}+4 } = 3

x^{2}+4 = 3^{2}

x^{2}+4 = 9

x^{2} = 9 -4

+x = \sqrt{5} ,  -x = \sqrt{5}
