Solve the system of equations using substitution.

Mathematics
1 answer:

Answer:

( \frac{1}{3}, 3 )

Step-by-step explanation:

Given the 2 equations

y = 9x → (1)

6x - y = - 1 → (2)

Substitute y = 9x into (2)

6x - 9x = - 1, that is

- 3x = - 1 ( divide both sides by - 3 )

x = \frac{1}{3}

Substitute x = \frac{1}{3} into (1) for corresponding value of y

y = 9 × \frac{1}{3} = 3

Solution is ( \frac{1}{3}, 3 )

Step-by-step explanation:

A

The probability of wining is 1/4 so it's 25%. so if you win you either win one of 2 object, so we have to divide the chance of wining by the number of object, so (25%)/2

A it's ,12.5% chance of wining the mug

B yes, it will change if she pics the mug first, it will be 25% because it's guaranteed that she will get the mug if she wins

Question Write an equation of the line passing through the point A(0, 3) that is perpendicular to the line y = −1/2x−6
White raven [17]

Answer:

The equation would be y=2x+3 I am pretty sure

Step-by-step explanation:

This is because you take the slope which is 2 from the line y=-1/2x-6. To find the slope perpendicular to the line, you need to find the exact opposite of the slope: -1/2, and in this case, it would be 2.

(Ex: if it was -3/4, you would need to use a slope of 4/3 since it is the opposite)

Then you take that slope (2) and the point (0, 3) and put it into "y-y1=m(x-x1)"

y-y1=m(x-x1)

y-3=2(x-0)

-distribute the 2-

y-3=2x-0

-add 3 on both sides-

so equation would be y=2x+3

Not sure if this is all correct, but I hope it helps! :)
