Answer:
1. 1 point
2. The x-coordinate of the solution = 2/17
3. The y-coordinate of the solution = -16/17
Step-by-step explanation:
Given that the equation is of the form;
y = -2³×x and y = 9·x - 2, we have;
y = -8·x and y = 9·x - 2
1. Given that the two lines are straight lines, the number of points of intersection is one.
2. The x-coordinate of the solution
To find a solution to the system of equations, we equate both expression of the functions and solve for the independent variable x as follows;
-8·x = 9·x - 2
-8·x - 9·x= - 2
-17·x = -2
x = 2/17
The x-coordinate of the solution = 2/17
3. The y-coordinate of the solution
y = 9·x - 2 = 9×2/17 - 2 = -16/17
y = -16/17
The y-coordinate of the solution = -16/17.
The answer would be 1 were to estimate
Answer:
B
Step-by-step explanation:
10% of 49.99
0.1 x 49.99 = 4.99
49.99 - 4.99 = 45.00
30% of 60.00
0.3 x 60 = 18
60 - 18 = 42.00
Length of each side = 11 cm
Solution:
Let a be the side of the square.
Side length of square = Side length of equilateral triangle
Therefore, side length of equilateral triangle = a
Perimeter of the square = Number of sides × side
= 4 × a
Perimeter of the square = 4a
Perimeter of the equilateral triangle = Number of sides × side
= 3 × a
Perimeter of the equilateral triangle = 3a
Sum of the perimeter of a square and equilateral triangle = 77 cm
⇒ 4a + 3a = 77
⇒ 7a = 77
Divide by 7 on both sides of the equation, we get
⇒ a = 11 cm
Length of each side = 11 cm.
