Answer:

The answer is B

Step-by-step explanation:

(−3x2)(5x−4x2−6)

=(−3x2)(5x+−4x2+−6)

=(−3x2)(5x)+(−3x2)(−4x2)+(−3x2)(−6)

=−15x3+12x4+18x2

=12x4−15x3+18x2

Which equation represents a line that passes through (5,1) and has a slope of 1/2?
netineya [11]

Answer:

C

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = \frac{1}{2} and (a, b) = (5, 1), hence

y - 1 = \frac{1}{2}(x - 5) → C

4/9 + 9/18. Please help me as soon as possible, it's due today.
Alik [6]

Answer:

\frac{17}{18}

Step-by-step explanation:

To solve 4/9 + 9/18 just find the common denominator which is 18.

to get 4/9 to get the denominator of 18 you multiply the denominator by 2:

9 x 2 = 18, what you do to the bottom you do to the top (Multiply the numerator by 2 also) so, 4 x 2 = 8.

Now, add the numerator and keep the denominator the same. 8 + 9 = 17.

8/18 + 9/18 = 17/18
