–t + 9t − 12t − –16t − 18t = –6

1 answer:

4 0

-t + 9t - 12t - (-16t) - 18t = -6
-t + 9t - 12t + 16t - 18t = -6
-6t = -6
-6t/-6 = -6/-6 (-6 on the left side cancels out so we are only left with T and our answer)
T = 1

ABC is a right triangle. If AB = 3 and AC = 7, find BC. Leave your answer in simplest radical form.

aivan3 [116]

1. Suppose that BC is hypotenuse, then by Pythagorean theorem:
$BC^2=AC^2+AB^2, \\ BC^2=3^2+7^2, \\ BC^2=9+49, \\ BC^2=58, \\ BC= \sqrt{58}$ .
2. If BC is not hypotenuse, then BC is a leg and AC is hypotenuse (because AC>AB). Hence by Pythagorean theorem:
$AC^2=AB^2+BC^2, \\ 7^2=3^2+BC^2, \\ BC^2=49-9, \\ BC^2=40, \\ BC= \sqrt{40} =2 \sqrt{x10}$ .

What is the solution to the system of equations? (7, 4) (7, startfraction 13 over 3 endfraction) (8, startfraction 14 over 3 end

miss Akunina [59]

The points are (7, 13/3).

Lets simplify the equation,

The equation of first line: y = 1/3 x + 2

the equation of second line: y= 4/3x - 5

Solve the system of equations by elimination,

Multiply equation A by -4 both sides

-4y = -4(1/3x +2)

-4y = -4/3x-8

After eliminating the equation we get,

y = 13/3

So now have to find x

13/3 = 1/3x + 2

Lets multiply above by 3
x = 13-6

x = 7.

Hence the points are (7, 13/3)

If 2x°,3x°, (2x°+10°) and x°+30° are the size of angles of a quardilateral, find them.

enyata [817]

Answer:

40 degrees

Step-by-step explanation:

2x + 3x + 2x + x + 10 + 30 = 360

Combine like terms

8x + 40 = 360

8x = 360 - 40

8x = 320

x = 320/8

x = 40

40 degrees
