grandymaker [24]
M(x) = 5x + 4     n(x) = 6x - 9

Part 1 (m + n)(x) = 5x + 4 + 6x - 9
                           = 11x - 5

Part 2 (m * n)(x) = (5x + 4)(6x - 9) = 30x^2 - 21x - 36

Part 3 m[n(x)] = 5(6x - 9) + 4
                       = 30x - 45 + 4
            = 30x - 41

Find the length between each pair of points (-1, 6) (7, 2)
Alexeev081 [22]

Answer:

\sqrt{80} or 4\sqrt{5}

Step-by-step explanation:

Using the distance formula:

d=\sqrt{(7-(-1))^2+(6-2)^2}=\sqrt{8^2+4^2}=\sqrt{64+16}=\sqrt{80}=4\sqrt{5}

Hope this helps!

What would be the answer???
nignag [31]

Answer:

120

Step-by-step explanation:

The sum of the angles in a quadrilateral is 360 degrees

2t+t+2t+t = 360

6t = 360

Divide by 6

6t/6 = 360/6

t = 60

Angle Z = 2t

Angle Z = 2*60 = 120

Solve the following equation for x.<br> 3x + 23y = 17
ZanzabumX [31]

Answer:

<u>The correct answer is x = 5 2/3 - 7 2y/3</u>

Step-by-step explanation:

1. Let's solve the equation for x

3x + 23y = 17

3x = 17 - 23y (Subtracting 23y at both sides)

3x/3 = 17/3 - 23y/3 (Dividing by 3 at both sides)

x = 17/3 - 23y/3

2. Proof of 17/3 - 23y/3 as the value of x

3x + 23y = 17

3(17/3 - 23y/3) + 23y = 17 (Multiplying the values inside the parenthesis)

17 - 23y + 23y = 17

<u>17 = 17</u>

<u>It has been proved that x = 17/3 - 23y/3</u>

<u>3. </u>However we can simplify

17/3 - 23y/3

<u>5 2/3 - 7 2y/3</u>

<u>There isn't a system of equations that will allow us to find y</u>
