Maru [420]

Answer:

Maria (I THINK)

Step-by-step explanation:

Tanya is running 70 yards in all, while maria would be running more based on the pythagorean theorem

The pythagorean theorem is that on a right triangle, the square root of the two legs equal the hypotenuse

40^2+ 70^2 =c^2

6500=c^2

square root both sides

and roughly c= 80.6 yards so maria runs more

(Im not sure it is a right angle though?)

Write 9x-3y=-69 x − 3 y = − 6 in slope-intercept form. Make sure you show all steps and inverse operations.Write 9x-3y=-69 x − 3
Goryan [66]

Answer:

y = 3x + 23 and

y = \frac{1}{3}x + 2

Step-by-step explanation:

The first equation is 9x - 3y = - 69 and we have to write it in slope-intercept form.

Now, 9x - 3y = - 69

⇒ 3x - y = - 23 {Dividing both sides by 3}

⇒ 3x + 23 = y

⇒ y = 3x + 23 {Interchanging the sides} (Answer)

The second equation is x - 3y = - 6 and we have to write it in slope-intercept form.

Now, x - 3y = - 6

⇒ x + 6 = 3y

⇒ 3y = x + 6 {Interchanging the sides}

⇒ y = \frac{1}{3}(x + 6) {Dividing both sides by 3}

⇒ y = \frac{1}{3}x + 2 (Answer)

Solve the linear system of equations <br> 8x−4y=20 5x−8y=62 <br> x= <br> y=
LUCKY_DIMON [66]

Answer:

x = -2

x = -9

Step-by-step explanation:

The linear system is:

8x - 4y = 20 ⇒ (1)

5x - 8y = 62 ⇒ (2)

To solve the system multiply equation (1) by -2 to make the coefficients of y equal in values and different in signs, then add the resulting equation with equation (2)

∵ -2(8x) + -2(-4y) = -2(20)

∴ -16x + 8y = -40 ⇒ (3)

- Add equation (2) and (3)

∴ -11x = 22

- Divide both sides by -11

∴ x = -2

Substitute the value of x in equation (1) or (2)

∵ 8(-2) - 4y = 20

∴ -16 - 4y = 20

- Add 16 to both sides

∴ - 4y = 36

- Divide both sides by -4

∴ y = -9
