Answer:

y=mx+b

5=2(-7)+b

5= -14+b

b= 5+14

b = 19

equation --> y=2x+19

Answer:

4762 N/m^2

Step-by-step explanation:

Find area.

30x5.6=168

Convert to m^2

168cm^2=0.0168m^2

Use pressure formula to get answer

P=F/A

P=80/0.0168

P=4762 N/m^2

Answer:

1. $\dfrac{4}{3}$

2. $y=6x-11$

3. $4$

Step-by-step explanation:

The equation of the line that passes trough the points A(14,-1) and B(2,1) is

$\dfrac{x-14}{2-14}=\dfrac{y-(-1)}{1-(-1)},\\ \\\dfrac{x-14}{-12}=\dfrac{y+1}{2},\\ \\y+1=-\dfrac{1}{6}(x-14),\\ \\y=-\dfrac{1}{6}x+\dfrac{7}{3}-1,\\ \\y=-\dfrac{1}{6}x+\dfrac{4}{3}.$

The y-intercept of this line is

$y=-\dfrac{1}{6}\cdot 0+\dfrac{4}{3}=\dfrac{4}{3}.$

Line BC is perpendicular to line AB, then its slope is $6.$ Line BC passes through the point B, so

$y-1=6(x-2),\\ \\y-1=6x-12,\\ \\y=6x-11.$

If the y-coordinate of point C is 13, then x-coordinate is

$13=6x-11,\\ \\6x=13+11,\\ \\6x=24,\\ \\x=4.$
