The anwsers are A.(0,-1) B.(-2,3) C(-4,0) D(0,-4)

shutvik [7]

Answer: D. (0, -4)

=========================================================

Explanation:

If you solve for y, you would get $y \le -\frac{1}{4}x-2$ . The less than or equal to sign shows we shade below the solid boundary line.

Of the four answer choices mentioned, only (0,-4) is in the shaded region. So this is the only solution.

If we plugged the coordinates into the inequality, we get a true statement as shown below

$x + 4y \le -8\\\\0 + 4(-4) \le -8\\\\-16 \le -8\\\\$

This is a true statement because -16 is to the left of -8 on the number line. So -16 is smaller.

In contrast, if we tried something like (x,y) = (0,-1), then we see...

$x + 4y \le -8\\\\0 + 4(-1) \le -8\\\\-4 \le -8\\\\$

Which is not true because -4 is actually larger than -8. Use a number line to see this. So (0,-1) is not a solution. The same can be said about (-2,3) and (-4,0) also.

The product of sin 30° and sin 60° is same as the product of cos 60 degrees tan 30 degrees and cos 30 degrees tan 60 degrees .

Pani-rosa [81]

From the unit circle:
sin 30 = 1/2, cos 30 = √3 / 2, tan 30 = √3 / 3 , tan 60 = √3;
sin 30 * sin 60 = ( cos 60 * tan 30 ) * ( cos 30 * tan 60 )
Left side of an equation:
sin 30 * sin 60 = 1/2 * √3 / 2 = √3 / 4
Right side:
( cos 60 * tan 30 ) * ( cos 30 * tan 60 ) =
= ( 1/2 * √3 / 3 ) * ( √3 / 2 * √3 ) =
= √3 / 6 * 3 / 2 = √3 / 4
√3 / 4 = √3 / 4 ( correct )

When estimating the cost of building a new house, Karmax Builders calculates $70 per square foot, $3,500 for miscellaneous expen

myrzilka [38]

Answer:

Step-by-step explanation:

70 is the slope.

70 represents the cost of one square foot.

Per every square foot (x), the cost increases by 70 (y).

The amount of square feet changes the total cost.

Equation is represented as:

$y=70x+3500$

3500 represents the y-intercept.

70 represents the slope.
