Solve for y, 2y=-4x-14

BabaBlast [244]

Hello from MrBillDoesMath!

Answer: y = 2x - 7

Discussion:

Divide both sides of the equation by 2:

2y /2 = (4x-14)/2 = 4x/2 -14/2

y = 2x - 7

Thank you,

BC = 36; D = 15. What is the value of BD - AC.<br> B<br> A<br> BD - AC =

Snezhnost [94]

Answer:

BD - AC = 0

Step-by-step explanation:

Given that:

BC = 36 , CD = 15 and BD = x

As these are forming right angled triangle,

Using Pythagorean theorem,

$(BD)^2+(CD)^2=x^2\\(36)^2+(15)^2 = x^2\\1296 + 225 = x^2\\1521 = x^2\\$

Taking square root on both sides

$\sqrt{x^2}=\sqrt{1521}\\x=39$

As the given shape is rectangular, the sides parallel to each other will have same values.

AB = 15 , AD = 36 and AC = x

$(15)^2+(36)^2 = x^2 \\225 + 1296 = x^2 \\1521 = x^2 \\x = 39$

Now,

BD - AC = 39 - 39 = 0

Hence,

BD - AC = 0

What is the value of x in the parallelogram CDEF if top left corner is 104 degrees and bottom right corner is (2x+16) degrees?

Travka [436]

Answer:

x = 44

Step-by-step explanation:

Opposite angles in a parallelogram are congruent, so ...

104 = 2x +16

88 = 2x . . . . . . subtract 16

44 = x . . . . . . . divide by 2

The perimeter of the semicircle is 25.71 cm. Calculate the value of radius x. Take pi to be 3.142

yan [13]

Answer:

5 cm

Step-by-step explanation:

$Perimeter of semicircle = \frac{1}{2} \times 2\pi \: x +2x\\ 25.71 = 3.14 2\times x+ 2x\\ 25.71 = 5.14 2 x\\ x = \frac{25.71}{5.142} \\ x = 5 \: cm$
