Answer:x = 1
y = 1
Step-by-step explanation:
The given system of simultaneous equations is expressed as
3x - 5y = - 2 - - - - - - - - - - - - 1
2x + y = 3 - - - - - - - - - - - - - 2
The first step is to decide on which variable to eliminate. Let us eliminate x. Then we would multiply both rows by numbers which would make the coefficients of x to be equal in both rows.
Multiplying equation 1 by 2 and equation 2 by 3, it becomes
6x - 10y = - 4
6x + 3y = 9
Subtracting, it becomes
- 13y = - 13
y = - 13/- 13 = 1
The next step is to substitute y = 1 into any of the equations to determine x.
Substituting y = 1 into equation 2, it becomes
2x + 1 = 3
2x = 3 - 1 = 2
x = 2/2 = 1
Given data:
The given figure.
The volume of the square pyramid is,
Thus, the volume of the square pyramid is 480 cubic-in.
Answer:
A, B and E
Step-by-step explanation:
y = (1/2)x has the form y = kx, with k = 1/2, its constant of proportionality.
A) 6y = 3x
y = (3/6)x
y = (1/2)x
B) We have to find the slope of the line. Using points (0,0) and (4, 2)
slope = (2 - 0)/(4 - 0) = 1/2
C) We have to find the slope of the line. Using points (0,0) and (2, 4)
slope = (4 - 0)/(2 - 0) = 2
D) We have to find the slope of the line. Using points (2,1) and (4, 3)
slope = (3 - 1)/(4 - 2) = 1
E) We have to find the slope of the line. Using points (4,2) and (10, 5)
slope = (5 - 2)/(10 - 4) = 1/2
yes
