How to find x (similar triangles)

Mathematics
1 answer:
hammer [34]3 years ago
3 0

Answer:

x = 2

Step-by-step explanation:

Parallel lines divides the transversals in proportion.

Therefore,

\frac{9}{4}  =  \frac{13.5}{x + 4}  \\  \\ 9(x + 4) = 13.5 \times 4 \\  \\ 9(x + 4) = 54 \\  \\ x + 4 =  \frac{54}{9}  \\  \\ x + 4 = 6 \\  \\ x = 6 - 4 \\  \\ x = 2

Help please! Identify an equation in point slope form for the line perpendicular to Y =-4x + 8 that passes through (-2, 7)
777dan777 [17]

Answer:

D. y-7=\frac{1}{4}(x+2)

Step-by-step explanation:

The point-slope form of a line is given by:

y-y_1=m(x-x_1)

The line given to us has equation; y=-4x+8.

The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.

Our slope of interest is therefore; m=\frac{1}{4}

Since the point goes through (-2,7), we have x_1=-2,y_1=7.

We plug in the slope and the point into the point-slope formula to obain;

y-7=\frac{1}{4}(x--2)

The required equation is:

y-7=\frac{1}{4}(x+2)

Hey I just need some help on this. :) Hallie hikes 5 mi in 90 min.
ELEN [110]
90 divided by 5 would be 18, so you want to do 18 times 2 I'm pretty sure, so it will be 36 minutes.

Answer my 2 questions-
kakasveta [241]

Answer:

1.  C   2. 4.95

Step-by-step explanation:

1.  Car payments are typically set so that the payments are equal (with the possible exception of the very last payment--sometimes called a balloon payment).

2. "Difference" implies a subtraction:  7.75 - 2.8 = 4.95.  That is not among the answers offered; could answe B be a typo?
