Step-by-step explanation:
Pls mark brainliest if correct!
Answer:5
Step-by-step explanation: Adding 3x+5x gives 8x, -3x is equal to 5x, so the coefficient is 5. Could I please have brainliest?
I'm not sure if this is a trick question, but the definition of a linear function prevents the function from having more than one y-intercept. x-values can't be shared in a function; there is a unique x value for every y value. at the y-axis, the value of x is 0. two y-intercepts would mean that x would be 0 for TWO points on the linear function, which doesn't pass the vertical line test and, therefore, isn't a function.
a graph CAN, however, have more than one x-intercept. the line y = 0, which passes the vertical line test and sits directly on top of the x-axis, has infinitely many x-intercepts and it is still a linear function.

Step-by-step explanation:
To solve all of these questions you just need to scale. While scaling you can divide or multiply.
1. (divide by 4 to get unit rate)
unit rate =
2. If it takes one hour to travel 40 miles, then we don't have to scale or anything. We know , the answer is...
"It'll only take one hour to travel 40 miles. This is correct because the unit rate is . "
3. Knowing that the constant speed of the plane is , we can scale then add half of the unit rate to get our answer.
x 3 = 800 x 3 = 2400
then add half of unit rate which is = 400
so, our answer is
4. <--- ( divided by 2) ( multiplied x 2.5) --->
To get an easier way to find the answer, if possible you can scale back farther than the 1 hour mark.
Elmer would take 2 and a half hours to ride 15 km.
5. The boys speed is . All we need to do is divide by 2. = 4
