I'm guessing 9.1 is a typo and it's suppose to be 9.0. In that case, the answer is D
Answer:
The coordinates of point E are (-19/4,8)
Step-by-step explanation:
To find this, we use the internal division formula;
The formula is as follows;
(x ,y) = mx2 + nx1/(m + n) , my2 + ny1/(m + n)
From the question;
m = 5 n = 3
x1 = -1 , y1 = -5
x2 = -7 , y2 = 11
Substitute these values;
(x ,y) = 5(-7) + 3(-1)/(3 + 5) , 5(11) + 3(-5)/(5 + 3)
(x , y) = (-35-3)/8, (55-15)/8
(x,y ) = -38/8, 40/8
(x,y) = -19/4, 5
An algebraic expression is a phrase in mathematics that consists of numbers such as 1,2,3 and the like, variables which are represented with letters and operations like addition, multiplication, subtraction and division. It is usually used to represent a certain situation which would relate the variables involved. To write the algebraic expression for the problem statement above, we do as follows:
Let x = number of consoles to be bought
y = number of games to be bought
z = number of controllers to bebought
C = total cost of all
The total cost would be equal to the sum of the price multiplied by the number of consoles, games and controllers bought. We write the algebraic expression as follows,
C = 299x + 59.99y + 29.99z
Solve for d by simplifying both sides of the equation, then isolating the variable.
D= -19/3
