Answer:
the answer is y=-0.556·x+7
Answer:
The units of the two shapes are not the same one is in cm the other in mm
Step-by-step explanation:
1cm=10mm
15÷10=1.5cm
12÷10=1.2cm
1.2×1.5=1.8
72- area of B
Area of B take away the area of A
72- 1.8
Answer=70.2cm
Answer:
Step-by-step explanation:
Given
Solving (1): k(2)
Take t as 2 such that t = 2
This gives
Solving (2): k(t) = 7
Substitute 7 for k(t)
Add 1 to both sides
Divide both sides by 2
Answer:
The solution to the system of equations is:
x = 2, and y = -1
Explanation:
Given the pair of equations:
4x + 5y = 3 ..........................................................................(1)
2x + 3y = 1............................................................................(2)
To solve this by elimination:
Multiply equation (2) by 2, to eliminate x
Equation (2) becomes
4x + 6y = 2 .........................................................................(3)
Subtract equation (1) from (3)
4x - 4x + 6y - 5y = 2 - 3
y = -1 ....................................................................................(4)
Multiply equation (1) by 3 and equation (2) by 5 to eliminate y
Equation (1) becomes
12x + 15y = 9 .......................................................................(5)
Equation (2) becomes
10x + 15y = 5 ........................................................................(6)
Subtract equation (6) from (5)
12x - 10x + 15y - 15y = 9 - 5
2x = 4
Divide both sides by 2
x = 4/2 = 2 ............................................................................(7)
From equations (7) and (4)
x = 2, and y = -1
