16.454 is greater than 16.45.
Step-by-step explanation:
y=4x+14
y=3x+15
-------------
y=7x+29
------------
7x+29
7x+29=0
7x=-29
7x/7=-29/7
x=-29/7
The length can be found using the Pythagorean Theorem...
c^2=a^2+b^2 and in this case:
d^2=(dx^2)+(dy^2)
d^2=(3-7)^2+(12-9)^2
d^2=-4^2+3^2
d^2=16+9
d^2=25
d=5
So the length of AB=5 units.
The point value is irrelevant. 18/24 as a decimal is 0.75, so your grade was 0.75, or 75%
Your grade is 75% in percentage form.
