Answer:
An egg and cheese biscuit was $3.65.
Step-by-step explanation:
Liam's breakfast was:
Where:
P: total price
E: egg
C: cheese biscuit
M: carton of milk
(1)
Now, Finn's breakfast was:
(2)
By subtracting equation (2) from (1) we have:
Hence, the price of a carton of milk is $2, so by entering this value into equation (1) we can find the price of an egg and cheese biscuit:
Therefore, an egg and cheese biscuit was $3.65.
I hope it helps you!
Answer:
1. Use a compass to make arc marks which intersect above and below then connect.
2.
Step-by-step explanation:
1. To construct a perpendicular line, use a compass to draw arc marks from one end of the segment through point P. Then repeat this again at the other end. This means at point P there will be two intersecting arc marks. Repeat the process down below with the same radius as used above. Then connect the two intersections.
2. The point slope form of a line is where
. We write
Since the line is to be perpendicular to the line shown it will have the negative reciprocal to the slope of the function 3x+y =-8. To find m, rearrange the function to be y=-8-3x. The slope is -3 and the negative reciprocal will be 1/3.
Simplify for slope intercept form.
