Answer:

B.In slope-intercept form, the slope is −79.These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is −AB.

Step-by-step explanation:

A is being moved to the other side of the equation so it has to be negative and is multiplied by B since the y value has to be divided to equal the base of y not 9y but y.

A commercial aircraft gets the best fuel efficiency if it operates at a minimum altitude of 29,000 feet and a maximum altitude o

natita [175]

Answer:

$x\geq 29,000$ and $x\leq 41,000$

Step-by-step explanation:

Let

x -----> the altitude of a commercial aircraft

we know that

The expression " A minimum altitude of 29,000 feet" is equal to

$x\geq 29,000$

All real numbers greater than or equal to 29,000 ft

The expression " A maximum altitude of 41,000 feet" is equal to

$x\leq 41,000$

All real numbers less than or equal to 41,000 ft

therefore

The compound inequality is equal to

$x\geq 29,000$ and $x\leq 41,000$

All real numbers greater than or equal to 29,000 ft and less than or equal to 41,000 ft

The solution is the interval ------> [29,000,41,000]

If x and y are both negative when is x-y positive

Vladimir [108]

X-y is positive when y is further away from 0, compared to x. In other words, when y is a larger negative

For example
x = -2
y = -5

x-y = -2-(-5) = -2+5 = 3

Y_Kistochka [10]

Answer:

1/2

Step-by-step explanation:

Pete found 5/6 of a party sand which in the refrigerator. He took 1/2 of the 5/6 of the sand which to his neighbors.

This is calculated as:

1/2 × 5/6

= 5/12

Hence, he took 5/12 of the sand

How much of the original sand which did pete take to his neighbors.

Let the original sand be represented as 1

Hence:

5/6 = 5/12 sand

1 = x

Cross Multiply

5/6x = 1 × 5/12

x = 5/12 ÷ 5/6

x = 5/12 × 6/5

x = 1/2

Therefore, pete took 1/2 of the original sand to his neighbors.
