Answer:look below
Step-by-step explanation:
To graph y= 4x +2 plot the point (0,2) on the graph because the y-intercept is 2 then use the slope: 4 to find another point. Another point would be (1,6).
Answer:
While x = -7 and y = 4, x² - 3xy = 133.
Step-by-step explanation:
x² - 3xy
Substitute variables.
(-7)² - 3(-7)(4)
Square -7 remembering that (-x)² = x².
49 - 3(-7)(4)
Multiply -7 and 4.
49 - 3(-28)
Multiply -3 and -28.
49 + 84
Add 49 and 84.
133
Answer:
d = 4
Step-by-step explanation:
- 6 - d = 6 - 4d ( add 4d to both sides )
- 6 + 3d = 6 ( add 6 to both sides )
3d = 12 ( divide both sides by 3 )
d = 4
99 gallons it takes 3 1/3 gallons to water 1 plant then multiply 3 1/3*30
