She can use 2x5 because that is the commutative property. commutative property of multiplication states that two numbers can be multiplied in either order, for example, 3x15 can also be multiplied in this way: 15x3. they will both make the same answer: 45
I'm pretty sure it's 7:35
Answer:
(2, 1): Yes
Step-by-step explanation:
5x - 3y = 7
-2x + 7y = 3
(2, 1) = 5(2) - 3(1) = 7
10 - 3 = 7
7 = 7
-2(2) + 7(1) = 3
-4 + 7 = 3
3 = 3
Yes
Answer:
D: x-int : (3, 0); y-int : None
Step-by-step explanation:
The concept is:
- The x-intercept is any point on the graph where the value of y is equal to 0.
- And, y-intercept is any point, where the value of x is equal to 0.
- Now, For the equation, x = 3, the x-intercept = 3 and the y - intercept = 0
- The graph of x = 3 is attached.
Hence, the correct answer is D: x-int : (3, 0); y-int : None
