All of a triangles angles added up make 180. when theres a 90, its a lot easier, all you have to do is take 180-90 which is 90 and divide 90 by 2 because there are two unknown angles which is 45 and angle A is slightly bigger than angle B (we'll say about 5 degrees bigger) so the answer would be 3) 50

Factor completely 54x4 + 2x

Margarita [4]

Answer:

2x+216

Step-by-step explanation:

The answer was easy to get because to factor you would just multiply the two numbers together to get 54x4 = 216 and then add the 2x, so your answer is 216+2x

Use the graph to estimate the solution to the system of equations shown.

Finger [1]

<h3>Answer: D. x= -5 1/2, y= -3 1/4</h3>

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

Explanation:

The solution occurs where the two lines intersect. From this intersection point, draw a vertical line upward until you reach the x axis. We arrive somewhere between -5 and -6. A good estimate is to say that we're at the midpoint, so x = -5 & 1/2 is one possible estimate

Since only choice D has this x value, this must mean choice D is the answer. The y coordinate of y = -3 & 1/4 seems to fit as well since we can draw a horizontal line from the point of intersection to the y axis, and arrive somewhere just a little below -3.

Hello! I don't understand how to do this question Triangle XYZ is located at X (−2, 1), Y (−4, −3), and Z (0, −2). The triangle

Katen [24]

ANSWER

EXPLANATION

Given that

X (-2, 1)

Y (-4, -3)

Z (0, -2)

The transformation rule of the triangle is given as

(x, y) ----------------> (x - 1, y + 3)

From, the given transformation rule, we can now find the new coordinates

X (-2, 1) --------------> X' (-2 -1, 1 + 3)

X(-2, 1 ----------------> X' (-3, 4)

Y(-4, -3) -----------------> Y'(-3-1, -3+1)

Y(-4, -3)-------------------> Y' (-4, -2)

Z(0, -2) --------------------Z'(0-1, -2+3)

Z(0, -2) -------------------> Z'(-1, 1)

Therefore the new coordinates of the triangles are

X' (-3, 4)

Y' (-4, - 2)

Z' (-1, 1)

The domain of the function is 80 to 180 because domain refers to the valid inputs of the function.

After receiving $42, the new domain (<em>that Albert can afford)</em> is from 80 to 147.
