Answer:

x=1 & y=6 or (1,6)

Step-by-step explanation:

3x-x+5=7   Substitute the 2nd equation in for y  

2x+5=7      Do 3x-x to get 2x

2x=2          Subtract 5 from both sides

x=1              Divide 2 from both sides

y=1+5          Insert 1 as x

y=6             Add 1+5 to solve for y

Hope this helped!

x =  \frac{ \sqrt{3} }{2}  \times  \frac{8 \sqrt{3} }{3}  \\

x = \frac{8 \times  { \sqrt{3} }^{2} }{2 \times 3}  \\

x =  \frac{8 \times 3}{2 \times 3}  \\

x =  \frac{8}{2}  \\

x = 4

In the diagram of circle R, m∠FGH is 50°. What is m? 130° 230° 260° 310°
omeli [17]

we know that

The measurement of the exterior angle is the semi-difference of the arcs which comprises

In this problem

∠FGH is the exterior angle

∠FGH=50\°

∠FGH=\frac{1}{2}(arc\ FEH-arc\ FH)

50\°=\frac{1}{2}(arc\ FEH-arc\ FH)

100\°=(arc\ FEH-arc\ FH)  -----> equation A

arc\ FEH+arc\ FH=360\°

arc\ FH=360\°-arc\ FEH --------> equation B

Substitute equation B in equation A

100\°=(arc\ FEH-[360\°-arc\ FEH])

100\°=2arc\ FEH-360\°

2arc\ FEH=360\°+100\°

arc\ FEH=230\°

therefore

<u>The answer is</u>

The measure of arc FEH is equal to 230\°

Help me with this pleassssseeeedeeeeeeee..

We’re told that QR and RS are equal, so this is an isosceles triangle.

Meaning the two base angles must also be equal

Using this information, we know that the third angle must be 180 - (22 + 22), since the angles in a triangle add up to 180

If a=5+2i, b=-3+i and c=4i(2+3I), determine ab+c in simplest a+bi form
Nady [450]

Answer:

-29+7i

Step-by-step explanation:

(5+2i)(-3+i)

-15+5i-6i+2i²

i²=-1

Simplify

-17-i

Add c

c=4i(2+3i)

=8i+12i²

=8i-12

-17-i+8i-12

-29+7i
