Answer:
A (first one)
Step-by-step explanation:
The arrow on the number line is going backwards, meaning less than. The open circle also plays a role.
Answer: A. intersecting
Step-by-step explanation:
1. To solve this problem and classify the system of equations shown above, you can graph it has you can see in the graph attached.
2. As you can see the lines intersect each other, this means that the system of equation has one solution and the lines are intersecting.
3. Therefore, the answer is the option A: Intersecting.
Answer:
I think 13 is C
Step-by-step explanation:
71+52= 123
180-123= 57
Answer:
A. y = 1x + 4
B. 1
C. 4
Step-by-step explanation:
The point (0, 4) is the y-intercept. So b = 4
y goes up each time by 1. So m = 1
Plug into y = mx + b
y = 1x + 4
In the second one I'm pretty sure you just measure the length of the points.
