2x(-5x-3)

2x(-5x)= -10x    and 2x(-3)= -6x

= -10x sq - 6x

-10x is sq bc you are multiplying the same variable twice

The variable y has a proportional relationship with
Nana76 [90]

Answer:

11

Step-by-step explanation:

Constant of proportionality, k, is the ratio of the quantity of variable y to the quantity of variable x.

Using a point on the line, (4, 44),

Constant of proportionality, k = \frac{y}{x} = \frac{44}{4} = 11.

Constant of proportionality of the graph is 11.

Ill give brainliest
yuradex [85]

Answer:

y-coordinate is 5 or -1.

Step-by-step explanation:

Point A is at (x, 2) and B is at (x+6, 2). Since AB must lie on the line y=2  and be 6 units long. Point C is on the line x = -3 . So let C be at (-3, y).

Since ΔABC is a right angle, then point C must have the same x-coordinate as point A. Therefore, A(-3, 2) and B(2, 2).

The area of ΔABC is 6. So,

9 = 1/2 (b)(h)

where b is the base and h is the height.

so b = 6 and h = AC

Solving this for C gives

9 = 1/2 (6)(AC)

18/6 = AC

3 = AC

9 = 1/2 (6)(AC)

18/6 = AC

3 = AC

Point C must lie 3 units above point A or 3 units below the point A. If it lies 3 units above, then it has a y-coordinate of 2 + 3 = 5.

If it lies 3 units below, it has a y-coordinate 2 - 3 = -1.

Therefore, y-coordinate is 5 or -1.

2. Find tan A for the right triangle below:
Andreyy89

Answer:

tan A=\frac{8}{15}

Step-by-step explanation:

According to the trigonometric ratios the tangent of an angle is the ratio of perpendicular to base, i.e.

tan\theta=\frac{Perpendicular}{Base}

In the provided triangle the perpendicular is 8 and base is 15.

Compute value of tan <em>A</em> as follows:

tan\theta=\frac{Perpendicular}{Base}\\tanA=\frac{8}{15}\\

Thus, the value of tan <em>A</em> is \frac{8}{15}.
