B you can tell just by look x^2*x^2=x^4
Answer:
A). Yes
B). Yes
C). No
D). Yes
Step-by-step explanation:
Coordinates of the midpoint of a segment joining two points 
and 
are given by 
.
A). If the points are A(1, 2) and B(3, 4)
Coordinates of the midpoint M → 
M → (2, 3)
Yes.
B). Extreme points of segment AB are A(0, 8) and B(10, -1)
Coordinates of the midpoint will be,
M → 
M → (5, 3.5)
Yes
C). Extreme points of segment AB are A(-7, -5) and B(6, 4)
Coordinates of the midpoint will be,
M → 
M → (-0.5, -0.5)
NO
D). Extreme points of segment AB are A(4, -2) and B(6, -8)
Coordinates of the midpoint will be,
M → 
M → (5, -5)
Yes
Answer:
For the first answer, I believe it to be A.
Step-by-step explanation:
For the top question, the only one that could come after 0.038 would be A.
Answer: 25%
Step-by-step explanation:
From the question, we are informed that Allison earned $200 the first month she worked and $250 the second month she worked.
The percentage increase in her salary will be calculated as:
= Salary Increase / Old salary × 100
= (250 - 200) / 200 × 100
= 50/200 × 100
= 1/4 × 100
= 25%
The percentage increase is 25%
Answer: Choice B
rose bush: $10, shrub: $4
=========================================
Work Shown:
x = cost for one rose bush
y = cost for one shrub
Rob's equation: 8x+5y = 100
Amy's equation: 8x+8y = 112
Subtract the equations straight down (match terms)
8x - 8x = 0x = 0, x terms go away
5y-8y = -3y
100-112 = -12
After those three subtractions, we end up with this new equation: -3y = -12
That equation solves to y = 4 when you divide both sides by -3
Use this value of y to find x
8x+5y = 100
8x+5(4) = 100 ... replace y with 4
8x+20 = 100
8x+20-20 = 100-20 .... subtract 20 from both sides
8x = 80
8x/8 = 80/8 ... divide both sides by 8
x = 10
We end up with x = 10 and y = 4 pairing up. The two equations, when graphed, cross at the location (10,4). One rose bush costs $10 and one shrub costs $4.
