sineoko [7]

The construction crew took $3\frac{3}{8}$ days to build $4\frac{1}{2}$ miles of road.

Therefore, in 1 day, the crew built $\frac{4\frac{1}{2} }{3\frac{3}{8} }$ miles of road

= $\frac{\frac{9}{2} }{\frac{27}{8} } =\frac{9}{2}times\frac{8}{27}=\frac{4}{3}$ miles of road

Thus, the required rate is $\frac{4}{3}$ miles or $1\frac{1}{3}$ miles per day.

It would be D because you need to multiply 38 and 50. But x is the length of one classroom, and because we don't know it, you would get 38(50-x).

Good luck!!

Answer:

$y=-\frac{9}{7}x-2$

Step-by-step explanation:

Here, we have to convert the equation to slope-intercept form so we can find the perpendicular slope:

$7x-9y=-5$

$-9y=-5-7x$

$y=-\frac{5}{9}+\frac{7}{9}x$

$y=\frac{7}{9}x-\frac{5}{9}$

Since our slope is $m=\frac{7}{9}$ , then that means the slope perpendicular to it is $m=-\frac{9}{7}$ .

Now we find our new y-intercept so that the line will pass through the point (-7,7):

$y=mx+b$

$y=-\frac{9}{7}+b$

$7=-\frac{9}{7}(-7)+b$

$7=9+b$

$-2=b$

Therefore, the equation of the new line is $y=-\frac{9}{7}x-2$
