Answer:

D. (2, -2)

Step-by-step explanation:

In a graph, the middle is the origin, and it is zero (0).

Positive sides:

The top side of the y-axis from the origin is positive.

The right side of the x-axis from the origin is positive.

Negative sides:

The bottom side of the y-axis from the origin is negative.

The left side of the x-axis from the origin is negative.

As we see the point labeled "Point A" on the graph, if we count from the x-axis, as we see, and the origin being 0, we notice it is "2". Since the point is on the right side of the x-axis, it is positive. The x-value is 2

When we count from the origin, as zero, we find the point lies in 2, as well. Since the point is on the bottom side of the y-axis, it is negative. Then the y-value is -2.

Option D is our answer.

Type the height of the ramp (h), in inches. Round your answer to the nearest whole inch.

sveta [45]

Answer:

49 inches

Step-by-step explanation:

To obtain the height, h of the ramp ;; we use trigonometry ;

h = opposite and the value of the hypotenus :

Sin θ = opposite / hypotenus

Sin 22 = h / 132

h = 132 * sin 22

h = 132 * 0.3746065

h = 49.44

Height of ramp = 49 inches

consider that a linear expression in the first step of simplification shown below which algebraic property was used to simplify

zvonat [6]

Answer:

The property used in the simplification is: Distributive Property.

Step-by-step explanation:

" The distributive property is used to combine the two terms that had the same variable. The distributive property is the key to combining expressions with like terms.

Terms are like terms when they have the exact same variables with the exact same exponents" .

Hence, the property used in the simplification of this expression is a distributive property.

What is the slope of a line perpendicular to the with equation y=6x+2? A.6 B.-6 C.-1/6 D.2

zhuklara [117]

The equation y = 6x + 2 is in the format which is called the slope-intercept form: y = mx + b where m = slope. Therefore the slope here is 6.
For the line perpendicular, the slope of it is a negative reciprocal from the original slope, that is m(perpendicular) = -1/m

Slope the line perpendicular is m(perpendicular) = -1/6. The answer is C.

Graph −8+x=4y−16 Use the line tool and select two points on the line.

dimulka [17.4K]

Answer:

The two ordered pairs you can use is (4, 3) and (8, 4). You can plot these and draw a straight line through these.

Step-by-step explanation:

In order to find the graph of the follow, first solve for y.

-8 + x = 4y - 16

-4y - 8 + x = -16

-4y -8 = -x - 16

-4y = -x - 8

y = 1/4x + 2

Now that we have this, we can find two points by choosing any two x's and solving for the y. For this case, we'll use 4 and 8.

y = 1/4x + 2

y = 1/4(4) + 2

y = 1 + 2

y = 3

So the first ordered pair is (4,3)

y = 1/4x + 2

y = 1/4(8) + 2

y = 2 + 2

y = 4

So the second would be (8. 4)
