The answer is 5r^2 -1
hope this helps !
In order to multiply or divide a fraction by a mixed numeral, it is best to have them BOTH in fraction form. 1) We'll convert 1 2/5 into an improper fraction. (1×5)+2 = 7/5
Now 6/7 ÷ 7/5
2) when dividing by a fraction, it is the same to multiply by its reciprocal. So flip the second fraction and multiply them: 6/7 ÷ 7/5 = 6/7 × 5/7
3) reduce them: there is nothing on top that reduces with the bottom, so we simply multiply
4) multiply numerators, then multiply denominators and keep them in place: 6×5 = 30, 7×7 = 49
5) so our final answer is 30/49
Answer:
what?
Step-by-step explanation:
Y = x + 3
to test all of these, just use the visible x-coordinates on the grid and substitute them in the equation.
eg; y = (2) + 3 --> y = 5 . So the line would cross through (2,5)
