Answer:
58.1 and 17
Step-by-step explanation:
For the first triangles the similarity ratio is 1:7 so x is 8.3 × 7 = 58.1
For the second triangles the similarity ratio is 1:5 so x is 3.4 × 5 = 17
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 to your question is C
Answer:
- 3x³-6x²
- 3x²+x-2
- -16
Step-by-step explanation:
For 1: Multiply both functions together, expand, then simplify
(x-2)(3x²) = 3x³-6x²
For 2: Just add both functions together
For 3: Subtract both functions to get -3x²+x-2 and substitute x with -2
-3(-2)²-2-2 = -16
Given:
Three fractions:
1) 2/5
2) -3/7
3) 2/3
The least is -3/7 because of the negative sign. Second is 2/5, and the greatest is 2/3.
-3/7 is -0.43 in decimal form
2/5 is 0.40 in decimal form
2/3 is 0.67 in decimal form
