The value is -8 of the expression
Step-by-step explanation:
3x + 5y = 21 * (-4) •••••• -12x -20y = -84 (a)
4x - 2y = -24 * (3) •••••• 12x -6y = -72 (b)
(a) + (b)
-26y = -156
y = 6
3x + 5 * 6 = 21
3x = 21 - 30
3x = -9
x = -3
Y = -5x + 12 since the slope of that line is -5x and in order to pass through that point the y intercept must be 12
Answer:
RP/QR = OP/NO
Step-by-step explanation:
RP corresponds to OP, QR corresponds to NO. So, RP/QR = OP/ON
Answer:
66
Step-by-step explanation:
complimentary angles add up to 90 so:
3x-6 + 2x +46 = 90
5x +40 = 90
5x = 50
x = 10
2(10)+46 = 66
3(10) - 6 = 24
