Please help..!!!!!!!
Morgarella [4.7K]

Answer:

E) (-4, -3)

Step-by-step explanation:

To use elimination, you need to have one variable in both equations that have the same coefficient. (The coefficient is the number attached to the variable). Both equations have "7y".

The way elimination works is by eliminating one of the variables first. Decide how (-7y) and (-7y) can cancel out and become 0. You can either add or subtract.

(-7y) - (-7y)        Try subtracting

= (-7y) + 7y

= 0

Based on this, we should subtract the whole equations.

Set up the equations like normal subtraction. Then, subtract each of the terms that have the same variable.

.   4x - 7y = 5

<u>-   9x - 7y = -15</u>       Do 4x - 9x = -5x.    -7y - (-7y) = 0.      5 - (-15) = 20.

.    -5x - 0 = 20       "y" cancelled out

.          -5x = 20          Isolate 'x'

.      -5x/-5 = 20/-5       Divide both sides by -5

.              x = -4          Solved x-coordinate

Substitute 'x' for -4 in any of the equations. Then simplify and isolate "y" to solve for the y-coordinate.

4x - 7y = 5

4(-4) - 7y = 5         Simplify the multiplication.

-16 - 7y = 5         Start isolating 'y' now

-16 + 16 - 7y = 5 + 16         Add 16 to both sides. Left side cancels out 16

-7y = 5 + 16         Solved right side by adding

-7y = 21

-7y/-7 = 21/-7         Divide both sides by -7

y = -3              Solved y-coordinate

Therefore the answer is (-4, -3).

Able, ben and cal each played a game.
iragen [17]

Answer:

Ratio of Able's score to Ben=6:1

Ratio of Ben's score to Cal's=1:2

Ratio of able's score to ben;s score to cal's score=6:1:2

Step-by-step explanation:

Let Ben's score =x

Able scored six times Ben's score

Able=6*x

=6x

Cal scored a third of Able's score

Cal=1/3 of 6x

=1/3(6x)

Ratio of Able's score to Ben

6x:x

=6:1

Ratio of Ben's score to Cal's score

x:1/3(6x)

=x:6x/3

=x:2x

=1:2

Ratio of able's score to ben;s score to cal's score=6:1:2
