Answer:

125/-3

Step-by-step explanation:

$\frac{ - {5}^{2} + {10}^{2} }{(2 \times ( - 5) \times 3) + {3}^{3} } \\ = \frac{25 + 100}{ - 30 + 27} \\ = \frac{125}{ - 3}$

If you look closely the area where 3x is congruent to the other side of the 90 degree angle with one part as 0.5x + 34

So
3x + 0.5x + 34= 90

x will be 16

So plug it in

0.5(16) + 34= 42 degrees

And

3(16)= 48 degrees

That left half of the circle is 180 degrees and since we know the angle 3x is 48 degrees we subtract it from 180 to get angle AE

180-48

132 degrees is your answer

Solve for y when x=15<br> 4x-3y=51

Naddika [18.5K]

4x - 3y = 51, when x = 15

Plug in 15 for x.

4(15) - 3y = 51

Simplify.

60 - 3y = 51

Subtract 60 from both sides.

-3y = 51 - 60

Simplify.

-3y = -9

Divide both sides by -3.

y = -9/-3

Simplify.

y = 3

5. Draw 2 line segment of different lengths that both have M as a midpoint.

Alona [7]

Step 1: Write out the coordinate of the midpoint

$M(-2,-3)$

Step 2: Find the coordinates of the two line segments by testing for values that will yeild the midpoint coordinates

$\begin{gathered} \text{ Since the midpoint M is at (-2,-3), then} \\ M(-2,-3)\Rightarrow(x_m,y_m) \\ x_m=\frac{x_1+x_2}{2}=-2 \\ y_m=\frac{y_1+y_2}{2}=-3 \end{gathered}$ $\begin{gathered} \text{Thus,} \\ x_1+x_2=-2(2)=-4 \\ y_1+y_2=-3(2)=-6 \end{gathered}$

From the above, we can deduce to four values that will give -4 for the x-values and -6 for the y-values.

$\begin{gathered} \text{For the first line segment},\text{ say line AB} \\ x_1+x_2=-6+2=-4,x_1=-6,x_2=2 \\ y_1+y_2=-9+3=-6,y_1=-9,y_2=3 \\ \text{Therefore, line AB coordinate is } \\ A(-6,-9),B(2,3) \end{gathered}$ $\begin{gathered} \text{For the first line segment},\text{ say line CD} \\ x_1+x_2=-10+6=-4,x_1=-10,x_2=6 \\ y_1+y_2=-14+8=-6,y_1=-14,y_2=8 \\ \text{Therefore, line AB coordinate is } \\ C(-10,-14),D(6,8) \end{gathered}$

Step 3: Draw the two lines segment on a cartesian plane showing M as the common midpoint.
