For the red line, we have:
gradient (
) = 1/3
y-intercept = 3
Equation of straight line is given by
, where
is the gradient and
is where the line intercept the y-axis
So we have,
The shaded part is above the line, hence the first inequality is
The black line, we have
gradient,
= 3
y-intercept = -2
, rearranging gives
The shaded region is to the right of the line, hence the inequality is
Note: The first option should be the correct answer but the inequality sign for <span>y > 1/3x + 3 should be </span>
Answer:
C gives you 90.2
Step-by-step explanation:
84+88+90+100=362
362/4=90.2
Answer:
AB = 7√2
Step-by-step explanation:
if a(x1,y1) and b(x2,y2) then
Based on your points and on the formula above AB is:
Answer: choice A
Step-by-step explanation:
You have to multiply each row by its corresponding column.
For example you multiply 1*5 and put it in the first row and first column(a1b1). you multiply 5*5 and put it in the second row and first column(a2b1) and so on.
when multiplying a 3*1 matrix by a 1*3 matrix you’ll get a 3*3 matrix.
