Given that, for x>3, f(x)=-1.

Therefore, f(5)=-1.

Also, given that for x=3, f(x)=-2x+2

Therefore,

\begin{gathered} f(3)=-2(3)+2 \\ f(3)=-6+2 \\ f(3)=-4 \end{gathered}

Therefore, f(3)=-4.

Let A (101, 202, 303, 404, 505) and B (101, 404). What is A n B?
Zepler [3.9K]
You should use curly braces instead of parenthesis to indicate set notation. The answer is {101, 404} as these two values are in both set A and set B at the same time. The upside down U symbol means "intersection" which is where the two sets overlap. In terms of a Venn Diagram, you'll have two overlapping circles. In the overlapping region is where 101 and 404 are written. In the region of circle A that is outside of B, you'll have 202, 303, and 505. There is nothing to write in the region of B that is outside of A (since all of B is inside A)

Once again, the answer is {101, 404}

Answer:

The surface area is 339.5 in^{2}

Step-by-step explanation:

The surface area of a 3-dimensional shape is calculated by adding the areas of each side together, which would be 24.5 + 52.5 + 52.5 + 105 + 105 = 339.5 inches squared.

(6,-3) and (x,-29); slope=-3
Sidana [21]

Answer:

x=44/3

Step-by-step explanation:


slope = (y2-y1)/(x2-x1)

substitute what we know

-3 = (-29--3)/(x-6)

simplify

-3 =(-29+3)/(x-6)

multiply each side by (x-6)

-3(x-6) = (-29+3)/(x-6) * (x-6)

the (x-6)'s on the right cancel

-3(x-6) = (-29+3)

distribute

-3x*-3*-6 = -29+3

-3x+18 = -26

subtract 18 from each side

-3x = -44

divide by -3

x = -44/-3

x=44/3
