5x+3y=6\\
3y=-5x+6\\
y=-\frac{5}{3}x+2\\
\boxed{m=-\frac{5}{3}}

To get the result we have to transform given formula into y=ax+b form.
Lets do this
5x+3y=6   /-5x  (subtract 5x both sides)
3y=-5x+6  /:3  (divide both sides by 3)
y=-\frac{5}{3} x+6
In form y=ax+b we know that a is slope and b is y intersect. We can read from our transformed equation that slope a=-\frac{5}{3}and its the result

debra buys a new mountain bike for 750 dollars . Sales tax is 9% . how much does Debra actually have to pay ?
Georgia [21]

Answer:

$817.50

Step-by-step explanation:

Hello  Matt7151!

To find the total amount, we will first need to find how much tax.

We can express 9% as the fraction \frac{9}{100}.

\frac{9}{100} × 750 = 67.50

So she's paying $67.50 sales tax.

750.00

  67.50

-------------------

 817.50

So Debra's really paying $817.50.

Thus, the answer is \boxed{$817.50}$$\boxed{817.50}$.

9x+2y-27z=-155 -11x-y+37z=208 19x+6y-52z=-304
Paladinen [302]

Answer:

(x,y,z)=( -2, -1 ,5)

Step-by-step explanation:

9x+2y-27z=-155                                                        (1)

-11x-y+37z=208                                                        (2)

19x+6y-52z=-304                                                     (3)

(1) *3   ;(2) *6     ;(3)*1, you have

27x+6y-81z=-465                                                      (1)

-66x-6y+222z=1248                                                 (2)

19z+6y-52z=-304                                                      (3)


(1) +(2), you have

-39x+141z= 783                                                       (4)

(4) /3, you have

-13x +47z=261                                                          (4)


(2) +(3), you have

-47x+170z=944                                                       (5)


From ( 4) and (5), you have equations

-13x +47z=261                                                         (4)

 -47x+170z=944                                                       (5)


(4)*(-47);    (5)*13,  you have

611x-2209z=-12,267                                              (4)

-611x+2210z=12,272                                              (5)


(4)+(5), you have

z=5

Replace z=5 in (4), you have

611x- 2209*5=-12,267

611x- 11,045 =-12,267

611x=-1222

x= -2

Replace x=-2, z=5 in (1) , you have

9*(-2) +2y -27*5=-155

-18+2y-135=-155

-18+2y=-20

2y=-2

y=-1

Result (x,y,z)=( -2, -1 ,5)
