A number raised to an exponent is the number multiplied by itself the number of times the exponent is.
The exponent is 3, so this means 0.25 is multiplied by itself 3 times.
0.25^3 = 0.25 x 0.25 x 0.25
You simply multiply the 3 numbers 12*4*16=768
Answer:
x = -7 and y = 5
Step-by-step explanation:
y = 3x + 19 equation(i)
y = 5x + 33
substitute the value of y
3x + 19 = 5x + 33
3x - 5x = 33 - 19
-2x = 14
x = 14/-2
x = -7
now substitute the value of x in equation (i)
y = 3x + 19
y = 3*-7 + 19
y = -14 + 19
y = 5
