5x + 3y = 22
y = 2x
Substitute y=2x into the first equation
5x + 3(2x) = 22
5x + 6x = 22
11x = 22
x = 2
Hope that helps :)
Answer:
169 knives
Step-by-step explanation:
What we know:
ZW threw 200 knives at Jotaro, then adds one more. This makes 201 knives, initially.
However, the RRD subtracts 32 from 201, making it 169 knives that ZW threw.
201 - 30 - 2 = 171 - 2 = 169 knives
Slope = rise/run = (change in y)/(change in x)
Slope = (4-6)/(0-(-4)) = (-2)/(4)
Slope = -1/2 = -0.5
Answer:
Step-by-step explanation:
x² + 3 = (-9)² + 3 { (-9)² = -9 *-9 = 81}
= 81 + 3
= 84
x + 6 = -9 + 6 = -3
