patriot [66]3 years ago

Answer:

Step-by-step explanation:

64

because the small triangle at the top is isoscel and has the base angles BDE and BED = (180 -48)/2 =66

angle BDE is congruent to DAC = 66, because 2 || BE and AC are cut by transversal BA

angle ADC = 180 -50 -66 = 64

1/a+1/b=1/x solve for x
VashaNatasha [74]

Answer:

x = \frac{ab}{b+a}

Step-by-step explanation:

Given

\frac{1}{a} + \frac{1}{b} = \frac{1}{x} ( express the sum on the left as a single fraction )

\frac{b+a}{ab} = \frac{1}{x} ( cross- multiply )

x(b + a) = ab ← divide both sides by (b + a)

x = \frac{ab}{b+a}

ExtremeBDS [4]
12 3/4 as a decimal is 12.75
The area of a rectangle is length times width.
So if you divide the area (12.75) by the length(3.4)
you will get a width (and answer) of 3.75 :)

What is the equation of a line with a slope of -4 and a point (-2,5) on the line
Lesechka [4]

Answer:

The equation of the line would be y = -4x - 3

Step-by-step explanation:

To find any equation when you have the slope and a point, start with point-slope form and then solve for y.

y - y1 = m(x - x1)

y - 5 = -4(x + 2)

y - 5 = -4x - 8

y = -4x - 3

Which statements correctly describe the transformation in the graph? Select all that apply.
elena-14-01-66 [18.8K]

Answer:

The correct statements: the first, the third and the fourth.

Step-by-step explanation:

The rule of rotation 180° (x, y) →(–x, –y) (Clockwise or Counter-clockwise)

The coordinates of BCDE⇒ B(2,1) , C(2,2) , D(4,2) and E(4,1)

The coordinates of JKLM ⇒ J(-2,-1) ,K(-2,-2), L(-4,-2) and M(-4,-1)

The coordinates of PQRS ⇒ P(-2,1), Q(-2,2), R(-4,2) and S(-4,1)

By applying the rule of rotation 180°, we can deduce that:

  1. BCDE is rotated 180° counterclockwise to form JKLM.
  2. JKLM is rotated 180° clockwise to form BCDE.
  3. JKLM is rotated 180° counterclockwise to form BCDE.
