Answer:
25x-y=-50
Step-by-step explanation:
Answer:
Step-by-step explanation:y–3=½(x+2)
Multiply through by the denominator (2).
2×y–2×3=½(x+2)×2
2y–6=1(x+2) because the denominator (2) will cancel the other 2 multiplying it
2y–6=x+2
2y=x+2+6
2y=x+8

Answer:
Length of hypotenuse of given triangle
= sqrt(356) (exact value)
= 18.87 (to 2 decimal places)
Step-by-step explanation:
Using the pythagorean Theorem,
The hypotenuse
c = sqrt(a^2+b^2)
= sqrt(16^2+10^2)
= sqrt(356) (exact value)
= 18.87 (to 2 decimal places)
