Is the point (1,4) on the line y=2x+3?

No

Step-by-step explanation:

The line y=2x+3 has a slope of 2 and a y intercept of (0,3). Plugging in x=1, we get y=2(1)+3=5, meaning that when x=1 the line is at (1,5). Since the line cannot be at (1,5) and (1,4) at the same time, (1,4) is not on the line.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
