X=-1
Step-by-step explanation:
3 • (x + 2) - (1 - 2x) = 0
5x + 5 = 5 • (x + 1)
5 • (x + 1) = 0
5 = 0
x+1 = 0
x = -1
The answer is 247 because you have to divide 6422 by 26.
Answer:
+- square root of x+36
Step-by-step explanation:
f(x) = x^2 -36
y = x^2 -36
Exchange x and y
x = y^2 -36
Solve for y
Add 36 to each side
x+36 = y^2 -36+36
x+36 = y^2
Take the square root of each side
±sqrt(x+36) = y
±sqrt(x+36) = f^-1(x)
It’s a complementary angle because it sum up to 90 degrees
She paid 5X cents in total. She sold 8(X -6). The profit was 450 cents.
So: 5X = 8(X-6) -450.
5X + 450 = 8X -48
3X = 402
X = 402/3 = 134. She bought 134 oranges.
