Triangle MNP is dilated to obtain triangle QRS. Using the same scale factor, triangle QRS is dilated to obtain triangle TUV. MN

30 meters, NP 25 meters, PM 25 meters, and QR 42 meters. What is the perimeter, in meters, of triangle TUV?

Answer: The perimeter of triangle TUV is 156.8 meters.

First, we need to find the scale factor that is used in the dilations. MN goes from 30 to 42 when it becomes side QR. Dividing 42 by 30 gives us a scale factor of 1.4.

The perimeter of triangle MNP is 80. Now, we have to multiply that by 1.4 twice to get to the perimeter of triangle TUV.


80 x 1.4 x 1.4 = 156.8

Which equation represents the line that passes through (–6, 7) and (–3, 6)? y = –y equals negative StartFraction one-third EndFr
DiKsa [7]

Answer:

y=-\frac{1}{3} x+5

Step-by-step explanation:

Notice that the answers they give you to choose from are all lines in slope y-intercept form, it would be very simple to just find the answer finding yourself the slope and y-intercept of the line in question.

Since they give you two points (x_1,y_1) and  (x_2,y_2) for the line, use them to find the slope of the line that goes through them, with the formula:  slope=\frac{y_2-y_1}{x_2-x_1} =\frac{7-6}{-6-(-3)} =\frac{1}{-3} =-\frac{1}{3}

Therefore, the slope of the line must be -\frac{1}{3}

Now, find the y-intercept (b) using the general form of a line with the given slope:

y=-\frac{1}{3}x +b

Use one of the given coordinate points to request that the line passes through it. For example, through the point (-3,6) (when x = -3, y must be 6):

y=-\frac{1}{3} x+b\\6=-\frac{1}{3}(-3)+b\\6=1+b\\b=6-1=5

then the y-intercept must be 5. Therefore our line is : y=-\frac{1}{3}x +5 which appears listed as your second choice.

Answer:

25

Step-by-step explanation:

In this equation, ax^2+bx+c, b = -1, a = 2, and c = -3. Solving, (-1)^2 - 4(2)(-3) = 1 - (-24), or 25.
