<em>≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡Ф</em>

Answer:

= −2k^3 − k^2 + 8k

Step-by-step explanation:

Let's simplify step-by-step.

−2k^3 − 7k^2 + 5^k + 6k^2 + 3^k

= − 2k^3 + −7k^2 + 5k + 6k^2 + 3^k

<em>Combine Like Terms: </em>

= − 2k^3 + −7k^2 + 5^k + 6k^2 + 3^k

= ( −2k^3 ) + (−7k^2 + 6k^2 ) + (5^k + 3^k)

<em>= −2k^3 + −k^2 + 8k</em>

<em>≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡Ф</em>

<em>Hope this helps!!! :)</em>

Aneli [31]

Given: Triangle JKL is dilated from the origin at a scale factor of 10 to create triangle J′K′L′.

Required: Correct option that complete the statement.

Explanation:

Now, triangle is dilated from the origin at a scale factor of 10.

So, the sides will become larger, but angles will remain the same.

Hence, the triangles will be similar as sides will be in proption (SSS rule).

So, The triangles are similar because their corresponding sides are proptional and their corresponding angles are congurent.

Final Answer: Second group is correct answer.

What is the slope of the line through (2,-2)(2,−2)(, 2, comma, minus, 2, )and (9,3)(9,3)(, 9, comma, 3, )? Choose 1 answer: Choo
svp [43]

Answer:

A)  \frac{5}{7}

Step-by-step explanation:

Use the two-points formula for the slope of a line.

We know that the points (2,-2) and (9,3) are on the line. If (a,b),(c,d) are points on a line then the slope m is defined by the equation m=\frac{d-b}{c-a}. In this case, a=2,b=-2,c=9 and d=3 then the slope is m=\frac{3-(-2)}{9-2}=\frac{5}{7}.
