Answer: (4.9x) - 3

Step-by-step explanation: the reason i didn't add an extra line thing is because the negative becomes the minus. the 4.9 is self evident

∆ABC is translated 6 units up and 3 units left to create ∆A'B'
guajiro [1.7K]

Keep in mind that the positive directions of the two axis are: upwards for the y axis and rightwards for the x axis.


So, translating a point 6 units up means to go 6 units along the positive direction on the y axis. For this reason, the new y coordinate will be 6 units more than the old one.


Similarly, going 3 units left means to decrease by 3 the x coordinate, because we're following the negative direction.


So, to recap, this transformation maps (x,y) \to (x-3, y+6)


This means that the two points become


A = (-1, 2) \implies A' ( -4,8),\qquad B = (1,5) \implies B' = (-2,11)

M/PQR if mzPQR = (10x 7), m/RQT = 5x°, and m/PQT=(4x+6).
vodomira [7]

The measure of ∠PQR will be 123° .

Interior Angles of an Angle:

An interior of an angle is a line that separates an angle into two angles. If BD is the interior of an angle ABC then the measure of the angle ABC is the sum of both the angles.

∠ABC = ∠ABD +∠DBC

We can divide an angle into many interior parts or angles.

If we have an angle and there are many interiors that divides the angle into many parts than the sum of all the interior angles is equal to the measure of the original angle.

If we have D and E are the two interiors of ∠ABC then ,

∠ABC =∠ABD + ∠DBE + ∠EBC

Given that point T is in the interior of ∠PQR  and ∠PQR =10x-7

                                                                                 ∠RQT =  5x°

                                                                              ∠PQT=(4x+6) .

Since T is the interior of  ∠PQR ,

∠PQR =      ∠PQT + ∠RQT

10x-7 = 4x + 6 + 5x

10x-7 = 9x + 6

x = 13°

So from the equation(1)-

∠PQR = 10(13) - 7

∠PQR = 123°

So ∠PQR = 123° .

West of a city, a certain eastbound route is straight and makes a steep descent toward the city. The highway has a 12% grade, wh
Masteriza [31]

Answer:

120 ft

Step-by-step explanation:

A slope of 12/100 means for every 12 units of distance you move horizontally you descend by 100 of the same units vertically. Assuming now that the slope does not change, i.e it remains constant throughout your trip; descending by 1000 ft should mean you have moved horizontally by 120 ft so that the slope is maintained.

x/1000 = 12/100

x = 120 ft
