Answer: b=9
Step-by-step explanation: To find the slope we use: y2-y1/x2-x1
Which would then be: 5-b/-2-7= 5-b/-9
Then we have to find a number for b that would give us -4 as the numerator. That number would be 9
This would give us 4/9 which is the slope we already had.
If the line is perpendicular, then as a rule the gradient of the perpendicular line will be the negative inverse of the gradient of the line given.
Therefore the gradient of the perpendicular line would be 1/2
so now just substitute in the equation of a line (y=mx+c) where y and x are given by -3 and 9, and your new m=1/2
Hope this helps
Answer:
$14
Step-by-step explanation:
The necklaces cost $8, so two would be $8+$8=$16
Now do the original $30 minus the $16 dollars spent
You now have $14 left.
