Answer:
x = 3
y = -5
Step-by-step explanation:
5x+2y= 5 equation 1
3х - у = 14 equation 2
using equation 2 we have:
3x - 14 = y equation 3
using equation 3 in equation 1 we have:
5x + 2(3x -14) = 5
5x + 6x -28 = 5
11x = 5+28
11x = 33
x =33/11
x = 3
using equation 3 we have:
3(3) - 14 = y
y =9-14
y = -5
³√250 = ³√2 ³√125 = 5 ³√2
<span>we need to show that ³√2 is irrational</span>
Answer:
five

when putting the image into a net you can count 5 sides
Answer:
The solution is y> -1
Step-by-step explanation:
y- 6 > -7
y> -7+6 (add 6 on both sides)
y> -1
The graph should the the first option from the right, with the dot above -1.
Since y is greater than -1, the dot should be on -1 and the arrow should be pointing towards the right. It shouldn't be a coloured dot because the sign is 'greater than' (>) not 'greater or equal to' (≥)
