Answer:

B. 136

Step-by-step explanation:

Δ ABC ≅ ΔEDC

AC/AB = CE/ED

(144-x)/51 = x/3

51x = 3(144-x)

51x = 432 - 3x

54x = 432

x = 8

AC = 144 - 8

AC = 136

Answer:

see the attached graph

Step-by-step explanation:

When an equation is in <em>standard form</em> (or almost standard form), I like to put it into <em>intercept form</em> for graphing. Here, it is convenient to divide the equation by 2 to put it in standard form (coefficients mutually prime).

x +3y = -3

Now, it is convenient to divide by the constant on the right (-3) to put the equation into intercept form:

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

The denominators are the x- and y-intercepts, respectively. Plot those, (-3, 0) and (0, -1), and draw the line through them.

In the picture lines AB and CD are parallel. Find the measures of

jasenka [17]

Answer/Step-by-step explanation:

1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°

2. m<ECF = m<BCD (corresponding angles)

m<ECF = 38° (substitution)

3. m<DCF + m<ECF = 180° (linear pair)

m<DCF + 38° = 180° (substitution)

m<DCF = 180° - 38° (Subtraction property of equality)

m<DCF = 142°

The system of equations y= 1/4 x-1and y=-1/2 x-1/4 shown on the graph below

Ksenya-84 [330]

Answer:

The value of x , y coordinate is ( 1, $\dfrac{-3}{4}$ )

and Plotting the points on graph

Step-by-step explanation:

Given as :

The system of equation is

y = $\dfrac{1}{4}$ x - 1

The equation can be written as

4 y = x - 4

Or, 4 y - x + 4 = 0 ........1

y = - $\dfrac{1}{2}$ x - $\dfrac{1}{4}$

The equation can be written as

4 y + 2 x + 1 = 0 ..........2

Solving the equation

i.e ( x - 4 ) + 2 x + 1 = 0

or, 3 x - 4 + 1 = 0

or, 3 x = - 1 + 4

∴ 3 x = 3

I.e x = 1

Put the value of x in eq 1

So, 4 y - x + 4 = 0

or, 4 y - 1 + 4 = 0

or, 4 y + 3 = 0

or, 4 y = - 3

∴ y = $\dfrac{-3}{4}$

So, The value of x , y coordinate is ( x ,y ) = ( 1 , $\dfrac{-3}{4}$ )

Hence The value of x , y coordinate is ( 1, $\dfrac{-3}{4}$ )
