Answer:
d. 23
Step-by-step explanation:
x: small hat
y: medium hat
z: large hat
We now write the system of equations:
x + y + z = 47
5.50x + 6y + 7z = 302
-3x + y = 0
We can write the system in matrix form as:
Ax = b
Where,
A = [1 1 1; 5.50 6 7; -3 1 0]
b = [47; 302; 0]
x = [x; y ; z]
Solving the system we have:
x = 6
y = 18
z = 23
hope this helps
correct me if this is wrong
Five. 7-2 is five. you are welcome lol
F x L = 3x10^10
L = 1x10^-11
F= 3x10^10 / 1x10^-11 = 3x10^21 unit
Answer:
y=-2x-4
Step-by-step explanation:
1) In this equation, -4 is the y-intercept (which is the point in the graph when x is 0 and y is something.)
2) Then, you have to check if the graph also has a y-intercept of -4 (it does)
3) Find out what the slope of the graph is. In this case, it is -2
4) If the equation also has a slope of -2 and y-intercept of -4, then it represents the graph.
Hope this helps :)
