Answer:
Option D RX=4 units
Step-by-step explanation:
we know that
<em>In the right triangle RTS</em>
The cosine of angle TRS is equal to
cos(TRS)=RT/RS
substitute
cos(TRS)=6/9 -----> equation A
<em>In the right triangle RTX</em>
The cosine of angle TRX is equal to
cos(TRX)=RX/RT
substitute
cos(TRX)=RX/6 -----> equation B
∠TRS=∠TRX -----> is the same angle
Match equation A and equation B
6/9=RX/6
RX=6*6/9=4 units
Answer:
the answer is 10
Step-by-step explanation:
We have that
5x - 2y = 10
we know that
Part A)
the x-intercept is when y=0
then
5x - 2y = 10------> 5x=10--------> x=10/5------> x=2
the answer Part A) isthe x intercept is the point (2,0)Part B)
the y-intercept is when x=0
then
5x - 2y = 10------> -2y=10------> y=-10/2-----> y=-5
the answer Part B) isthe y intercept is the point (0,-5)see the attached figure
Answer:
The reciprocal of 16 is 1/16
Step-by-step explanation:
The reasoning for this is that the reciprocal of any number is the opposite of it.
Another example would be: The reciprocal of 1/2 would be 2/1
Answer:

Step-by-step explanation:
-5*2 - 1 = -11
-5*-11 - 1 = 54
