Choose the equation below that represents the line that passes through the point (7, -2) and has a slope of -3

Norma-Jean [14]

Answer:

Option C

Step-by-step explanation:

All of these equation have a slope of x=-3, as this is the only number that will be acompanied by an x (the slope of a function is the number on the equation that has an X). To know which one of this equations passes through the points (7;-2) we can supplant these numbers on each equation until the result at both sides are equals.

The correct answer is the option c, because if we supplant these numbers (x=7 and y=-2) on the equation, we get an equality.

$y + 2 = -3. (x - 7) // -2 + 2 = -3. (7 - 7) //0 = 0$

Find sin R.<br> a. sin R= 29/21<br> b. sin R= 21/20<br> c. sin R= 20/29<br> d. sin R= 21/29

krok68 [10]

Answer:

sin R = 20 / 29

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin R = opp / hyp

sin R = 20 / 29

Select the correct answer from each drop-down menu. Shape I is similar to shape II. The sequence that maps shape I onto shape II

AURORKA [14]

Answer:

Scale factor 2.

Step-by-step explanation:

The vertices of shape I are (2,1), (3,1), (4,3), (3,3), (3,2), (2,2), (2,3), (1,3).

The vertices of shape II are (-4,-2), (-6,-2), (-8,-6), (-6,-6), (-6,-4), (-4,-4), (-4,-6), (-2,-6).

Consider shape I is similar to shape II. The sequence that maps shape I onto shape II is a 180 degree clockwise rotation about the origin, and then a dilation by a scale factor of k.

Rule of 180 degree clockwise rotation about the origin:

$(x,y)\rightarrow (-x,-y)$
