Answer:
4y = -x + 9
Step-by-step explanation:
2y = 8x - 6
Divide through by 2:-
y = 4x -3 so the slope of this line = 4
Slope of the line perpendicular to this = -1/4
So using the point/slope form of an equation of a line and the point (-3,3) we have:-
y - 3 = -1/4(x - -3)
y = -1/4x - 3/4 + 3
y = -1/4 x + 9/4 Multiply through by 4:-
4y = -x + 9
Answer:
do you have a picture with the problem written out?
Answer:
A 13.75
Step-by-step explanation:
because you said the you 1 ponit for every right ans and -0.25 for incorret ans so 15 right ans would give you 15 ponits and 5 incorret ans would give you -1.25 so i add up
15+-1.25=13.75 or 55/4
i did do the math so it is right
To find the solutions to the system, we need to find exactly when one expression is equal to the other. We can do this by setting both of the right sides equal to each other, so that
Subtracting x+6 from either side, we find
factoring out an x+6:
The x-coordinates of our solutions will therefore be 6 and -6. Since the question only asks for the <em>x-coordinate</em> of the midpoint, we simply need to find the number exactly halfway between 6 and -6, which is 0.
Answer:
½
Step-by-step explanation:
12 girls
So, 20-12 = 8 boys
6 didn't bring lunch box
So, 8-6 = 2 brought lunch box
2 boys and 8 girls brought lunch box.
10/20 brought lunch box
Probability = 10/20 = ½
