The gradient of the original line is 4. For a perpendicular gradient, you use the negative reciprocal, which is -1/4. Using y - y1 = m(x - x1), you can solve that y - 5 = -(1/4)(x - 2).
Multiply through by -4, you get -4y + 20 = x - 2, which can be rearranged as x + 4y = 22
Step-by-step explanation:
A potter can make 6 small plates in one hour, h.
=> So to make 1 small plates, a potter needs: 1/6 hour
Yesterday, the number of small plates the potter made was:
=> Number of small plates = Total plates - Number of large plates= 23 - 5 = 18 plates
=> Hours the potter needed to make 18 small plates were: <em>Number of plates x Hour to make 1 plate = 18 x (1/6) = 3 hours</em>
<em />
<em>=> Hours the potter spent working on small plates were 3 hours.</em>
<em />
<em>The equation is: </em>
<em>Hours spent working on small plates </em>
<em>= Number of small plates made x Time to make 1 small plates </em>
<em>= (1/6) x number of small plates made (hours)</em>
Answer:7.5
Step-by-step explanation:
you divided 15 into 2
The correct answer for part A is 5x² +7x -4. 5x³ -x² -8x -7 is the right answer for part B. Polynomials are always closed if under addition or subtraction. The answers of both parts A and B are polynomials.
Hope this helps!
