Answer:
v = -3i - 2j
Step-by-step explanation:
Vector given two points:
Given two points, a vector is the subtraction of the terminal point by the initial point.
In this question:
Initial point: (-1, 4)
Terminal point: (-4, 2)
So
v = (-4,2) - (-1, 4) = (-4 - (-1), 2 - 4) = (-3,-2)
The vector is v = (-3,-2)
In component form:
xvalue is i, yvalue j. So
v = -3i - 2j
Answer:
3
Step-by-step explanation:
x= total minutes -4 the 1st 4 minutes are included in the .30
total cost = .3 + .18 x
3 = .3 +.18 x
subtract .3 from each side
2.7 = .18x
divide by .18 on each side
2.7/.18 = x
15 = x
x = total minutes -4
add 4 to each side
15+4 = total minutes
they can talk 19 minutes
Answer:
11x²y³ - 4xy²
Step-by-step explanation:
remove the parenthesis and collect like terms
4x²y³ + 2xy² - 2y + 7x²y³ - 6xy² + 2y
= (4x²y³ + 7x²y³) + (2xy² - 6xy²) + (- 2y + 2y)
= 11x²y³ - 4xy² + 0
= 11x²y³ - 4xy²
