Answer:
B
Step-by-step explanation:
You should find the solution for this system of equations (The value of x is the first coordinate for the point of intersection, the value of y is the second coordinate for the point of intersection)
X+y=0.3
y=3x+16.7
use 3x+16.7 instead of y in the first equation(do it to get only x in the first equation)
x+3x+16.7=0.3
4x+16.4=0
4x=-16.4
x=-4.1
y=0.3+4.1=4.4
B
The answer is c because you can use your eyes
Answer:
a)45min
b)900min
Step-by-step explanation:
We were told that it takes Matt 3 minutes to read one page in a book.
It implies that 3minutes = 1page of the book
Then he continues to read at the same pace, he can read 15 similar pages in minutes.
a)Then, he can read 15 similar pages in
15x3 minutes.which is 45minutes.
b)Then if the book has 300 pages, it will take him. 300×3 minutes to read it.which is 900mins
A parabola is the locus of points equidistant from the focus and directrix. This means the distance from the green point is the same to the focus as it is to the directrix. The appropriate choice is ...
