Answer:
(-3, -4)
Step-by-step explanation:
The solution is where the two lines intersect. Therefore, the x-coordinate is -3, and the y-coordinate is -4.
Another way to solve this would be to set the to equations equal to each other, so 2x+2 = -4. Therefore, 2x = -6, and x = -3. And from the second equation, y = -4.
Train one is going 75 m/s, train two is going 60 m/s, and train three is going 65 m/s.
Explanation:
For number one you could use the slope formula y2-y1/x2-x1, or you could simply just view it from the table that every second that’s passes the distance goes up another 75 meters. This means it would be 75 meters per second.
For the second one it’s a positive correlation that’s related meaning at every whole second (1,2,3...) the line will pass through it, so all you have to do is look at the left and see how much it’s going up by because we know it’s going up by the same amount each time.

You have to simplify the first equation until you get x= something.
The fill that in the x spot in the second equation.
Question 4.
The multiples of 7 are those numbers obtained from the product of 7 and a whole number.
The multiples of 7 between 50 and 70 are:
You could be 56 or 63
Answer:
False
Step-by-step explanation:
The bigger the negative number the less it is, so -11 is less than 11. -33 is less than 33.
