Point A is located at (-2, -6) and is translated 4 units up. What are the coordinates of point A'?

Its A because the vertical line is the y-axis so 4+-6 is -2 and the x-axis would remain the same. #TeamAlvaxic

3x^3-2x^2-147x+98=(ax-c)(bx+d)(bx-d) where a,b,c and d positive integers. Work out the value of a,b,c and d

Alexxx [7]

Expand the right side:

$(ax-c)(bx+d)(bx-d)=(ax-c)(b^2x^2-d^2)$

$=ab^2x^3-b^2cx^2-ad^2x+cd^2$

Notice that 98 = 2 * 7 * 7, so we have $c=2$ and $d=7$ .

Then

$-ad^2=-147\implies a=\dfrac{147}{49}=3$

and

$ab^2=3\implies b^2=1\implies b=1$

Please answer for BRAINLIEST!

Answer:

1.5 units squared

Step-by-step explanation:

Area of a Triangle formula: A = 1/2bh

Pythagorean Theorem: a² + b² = c²

Since you are missing the h to find the area of the triangle, you must use Pythagorean to find the 3rd missing side (it is a right triangle so you can use Pythagorean).

Step 1: Use Pythagorean

2.5² = 1.5² + b²

4 = b²

b = 2

Step 2: Switch variables

b (from Pythagorean) = h (height for Area)

Step 3: Solve for Area

A = 1/2(1.5)(2)

A = 1.5

And you have your final answer.

The probability of having a winning raffle ticket is 20%. If you bought 50 tickets, how many winning tickets should you expect t

dem82 [27]

20% can be represented as 1/5.

Therefore you're expected to win 1 ticket out of every 5 you purchase. So if you purchase 50 you can expect to win 10 tickets. Therefore the answer is C.
