Answer:
D. y = 2.30x
Step-by-step explanation:
If he makes $230 for every hundred, that 2.30 a pop, so 2.30x for x apps.
Answer:
(- 1, 1 )
Step-by-step explanation:
x + 5y = 4 → (1)
4x + 12y = 8 → (2)
multiplying (1) by - 4 and adding to (2) will eliminate x
- 4x - 20y = - 16 → (3)
add (2) and (3) term by term to eliminate x
0 - 8y = - 8
- 8y = - 8 ( divide both sides by - 8 )
y = 1
substitute y = 1 into either of the 2 equations and solve for x
substituting into (1)
x + 5(1) = 4
x + 5 = 4 ( subtract 5 from both sides )
x = - 1
As a check
substitute these values into the left side of both equations and if equal to the right side then they are the solution.
- 1 + 5(1) = - 1 + 5 = 4 = right side
4(- 1) + 12(1) = - 4 + 12 = 8 = right side
(- 1, 1 ) is the solution to the system of equations
The product of the lengths of the parts of the chord is equal to the product of the lengths of the parts of the chord that divides it.
(7 cm)*(8 cm) = n*(4 cm)
(7*8 cm²)/(4 cm) = n
14 cm = n
