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

2x+1/4=4x-9/8 Is it a no solution or real

Naddika [18.5K]

Answer:

The equation has a real solution which is:

$x=\frac{11}{16}$

Step-by-step explanation:

Given the equation

$2x+\frac{1}{4}=4x-\frac{9}{8}$

Solving the equation

$2x+\frac{1}{4}=4x-\frac{9}{8}$

Subtract 1/4 from both sides

$2x+\frac{1}{4}-\frac{1}{4}=4x-\frac{9}{8}-\frac{1}{4}$

Simplify

$2x=4x-\frac{11}{8}$

Subtract 4x from both sides

$2x-4x=4x-\frac{11}{8}-4x$

Simplify

$-2x=-\frac{11}{8}$

Divide both sides by -2

$\frac{-2x}{-2}=\frac{-\frac{11}{8}}{-2}$

Simplify

$x=\frac{11}{16}$

Therefore, the equation has a real solution which is:

$x=\frac{11}{16}$
