Answer:
C
Step-by-step explanation:
2 times 10 is 20. 2 times x is 2x. 2 times -4 is -8. So that gives you 20+2x-8. Combine like terms, so you don't have anything that matches with 2x, so you leave that aside. So you subtract/add 20-8 which gives you 12 and add the 2x on that. So the full answer is 2x+12.
The relationship between radius (r), angle (θ), and arc length (s) is given by
.. s = r*θ . . . . . . . . θ in radians
.. s = (5 cm)*(210π/180)
.. s = 35π/6 cm
.. s ≈ 18.33 cm
Answer:
matrices can be added together if both have the same order
Addition is both commutative and associative
matrices can be multiplied together if the number of column in the right hand matrix equals the number of row in the left hand matrix
The points in the graph are (-1,0) and (3,0). I solved the equation using the Factoring method in solving quadratic equations. As I solved for finding x= -1 and 3, I substituted both to the equation in order to find y.
Answer: x=247
Step-by-step explanation:
1. Set up the equation
117/45=x/95
2. Cross multiply
117(95) = 11115
45(x)= 45x
3. Set both equal to each other
11115=45x
4. Divide 45 on each side
11115/45 = 45x/45
5. Solve for x
x=247
