Answer:
8 + 6t
Step-by-step explanation:
just distribute the negative signs in front of the parenthesis which is technically just -1
or if its easier, just multiply the numbers inside the parenthesis by -1 and get rid of the parenthesis
Answer: for part b it would be y=x16
Step-by-step explanation:
because theres 16 pencils in one box so to get 32 for the second box you multiply 2 by 16 and so on and so forth
False;
We are given the equation:
y = 4x - 19
This is a line with a gradient (more accurate term for slope) of 4;
The negative reciprocal of 4 is -1/4;
The other line given has a gradient of only 1/4, not -1/4, therefore, the equations do not match up with the given information.
Tip: In the situation where a line has a gradient that is the negative reciprocal of the gradient of another line, the two line will be perpendicular (i.e. the subtended angle from the point of intersection of the two lines will be 90°).

1/9 because i you plug in two of the points into y2 -y1 over x2 -x1 thats what you get.
