I have my Math test coming up. I got 2 chapters that I need to prepare for. 1. Direct and Indirect Proportion/Variations
2. Indices and Standard Form

My school uses Oxford's New Syllabus Mathematics 7th Edition Book 2 and Book 3.

Can someone explain me these topics briefly? Tell each topic's formula and what it is and why it is what it is. I'll really appreciate if you take your precious time out. If I had any further queries on your answer I'll ask through comments, hope you'll reply. Thank you! ​

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

your answer is 125y5
