Answer:
Daughter age = 3 years
Step-by-step explanation:
Let x be the age of the women and y be the age of the daughter.
Given:
After five year the sum of the women and daughter age = 40
At present the sum of the women and daughter age
--------------(1)
So the sum of the present age is
The difference in their present age is 24 years.
Now we substitute x value in equation 1.
Therefore, the daughter age is 3 years.
Answer:
7y + 24
Step-by-step explanation:
Think of the negative sign to the left of the parentheses as being -1. Then apply the distributive property. The effect of a negative sign to the left of parentheses or a 1 to the left of parentheses is that each term inside the parentheses changes sign.
-(-7y - 24) = -1(-7y - 24) = (-1)(-7y) - (-1)(24) = 7y - (-24) = 7y + 24
A'(1,-2)
B'(1,-3)
C'(-1,-3)
D'(-1,-2)
1 A. 5
1 B. 12.9
2. For this one, u can write any number less than 4.7, which could be 3, 2, -100, 1.21, etc.
3. For this one, u can write any number greater than (positive!) 2.6, such as 10, 30, 3.1415, etc.
hope this helps!
Answer:
v = -8i - 6j
Step-by-step explanation:
The starting point is (9, 9)
The direction of the vector is the direction of the arrowhead.
The i is the horizontal component.
The j is the vertical component.
Therefore, to go from the start to the end of the line, we need to travel negative 8 units (horizontally) and negative 6 units (vertically).
Therefore, v = -8i - 6j
