Mathematics
1 answer:
miskamm [114]3 years ago
8 0

Answer:

Step-by-step explanation:

Diagonals intersect at 90

2z - 8 = 90

    2z  = 90 + 8

  2z = 98

    z = 98/2

z = 49

Adjacent sides are congruent

5x - 12 = 3x + 2

5x  = 3x + 2 + 12

5x = 3x + 14

5x - 3x = 14

2x = 14

x = 14/2

x = 7

3x + 2 = 3*7 + 2

          = 21 + 2

          = 23

Use Pythagorean theorem to find y

16² + y² = 23³

256 + y² = 529

          y² = 529 - 256 = 273

          y = √273

         y = 16.52

Find the equation of the line through point (-2,-2)and parallel to 3x+4y=12
Maurinko [17]
Parallel = same slope
Turn 3x + 4y = 12 into y = mx + b
3x - 12 = -4y
-4y = 3x - 12
Divide by -4
Y = -3/4x + 3
Now: y = -3/4x + b
Plug in the point (-2,-2)
-2 = -3/4(-2) + b
-2 = 1.5 + b
b = -3.5
Equation: y = -3/4x -3.5

-3(4u-v)-5(-v+3u)<br> For 20 points
natita [175]

Answer:

−27u + 8v

Explanation:

−3(4u − v) − 5( − v + 3u)

[ Distribute ]

= (−3)(4u) + (−3)(−v) + (−5)(−v) + (−5)(3u)

= −12u + 3v + 5v + −15u

[ Combine Like Terms ]

= −12u + 3v + 5v + −15u

= (−12u + −15u) + (3v + 5v)

= −27u + 8v
