4 0

Answer:

=−30x−62

Step-by-step explanation:

Distribute:

=−3+(−3)(2x)+(−3)(7)+(−4)(6x)+(−4)(7)+−10

=−3+−6x+−21+−24x+−28+−10

Combine Like Terms:

=−3+−6x+−21+−24x+−28+−10

=(−6x+−24x)+(−3+−21+−28+−10)

=−30x+−62

Answer:

=−30x−62 i think :)

What is the midpoint of (-23,-14) and (-18,2)
zloy xaker [14]

Given two coordinates point 1 as (-23,-14) and point 2 as(-18,2).

To find the midpoint we would use the formula below;

\text{midpoint(x,y)}=(\frac{x_1+x_2_{}_{}}{2},\frac{y_1+y_2}{2})

Where x1=-23, x2=-18, y1=-14, y2=2

We would substitute the values into the midpoint formula.

\begin{gathered} \text{midpoint =(}\frac{-23-18}{2},\frac{-14+2}{2}) \\ =(-\frac{41}{2},-6) \end{gathered}

Therefore, the answer is

\text{midpoint}=(-\frac{41}{2},-6)

| the British 50-pence coin shown on the right is in the shape of a
Sergio [31]

For a regular polygon with n sides, interior angle

= [(n-2) × 180°]/n

So, interior angle of this regular heptagon shape

= [(7 - 2) × 180°]/7

= (5 × 180°)/7

= 900°/7

= (900/7)°

= 128.571° [approximately]

Solve the inequality. 3/4x−2/3≤5/6 Choose the solution that is graphed on this number line.
Gemiola [76]

Answer:

<em>x ≤ 2</em>

<em>(when graphed, closed circle on two, shaded to the left)</em>

Step-by-step explanation:

3/4 x - 2/3 ≤ 5/6

Add 2/3 to both sides:

3/4x ≤ 5/6 + 2/3

3/4x ≤ 3/2

Divide by 3/4 on both sides:

x ≤ 3/2 ÷ 3/4

x ≤ 2
