Answer:

Step-by-step explanation:
First, find the magnitude of the vector:

Then, divide each component of the vector by the magnitude to get the unit vector and rationalise:

<span> x+2a=4x
2a = 3x
a = 3x/2
a =1.5x</span>
Answer:
Each line segment joining a vertex of ABCD to the corresponding vertex in the image is perpendicular to the line of reflection, EF. That is, the lines intersect at a 90 degree angle.
Answer:
option-A
Step-by-step explanation:
For company-1:
d=3m+5
so, the rate of change =3
For company-2:
we can find rate of change
rate of change is


now, we can use point slope form of line
y1=12 , x1=0


We can see that
rate of change of first company(3) is greater than rate of change of second company(1)
Answer:
d = 1.2e
30 dollars
Step-by-step explanation:
To write an expression, define the variables. E will be the number of euros and d will be dollars.
"Euro was equal to about 1.2 American dollars" is one euro equals 1.2 and two euros equals 2.4. So the expression is d = 1.2e.
This means if I have 1 euro, I have 1.2*1 = 1.2 dollars. If I have 2 euros, I have 1.2*2 = 2.4 dollars.
If I have 25 euros then d = 1.2*25 = 30 dollars.
