Answer:

y = 0

x = 7

Step-by-step explanation:

2x − 9y = 14     ⇒  ( 1 )

x = − 6y +7      ⇒ ( 2 )

First, let us find the value of y.

<u>For that, replace x with ( - 6y + 7 ).</u>

<u>Let us take equation 1 for that.</u>

2x − 9y = 14

2 ( - 6y + 7 ) - 9y = 14

-12y + 14 - 9y = 14

21y = 14 - 14

21y = 0

<em>Divide both sides by 21.</em>

<u>y = 0</u>

<u>And now let us take equation 2 to find the value of x by replacing y with 0.</u>

2x − 9y = 14    

2x - 9 × 0 = 14

2x - 0 = 14

2x = 14

<em>Divide both sides by 2.</em>

<u>x = 7</u>

Step-by-step explanation:

put \: x \: into \: equation \: 1

2( - 6y + 7) - 9y = 14

- 12y + 14 - 9y = 14

- 21y + 14 = 14

- 21y = 14 - 14

- 21y = 0

\frac{ - 21y}{12}  =  \frac{0}{21}

y = 0

put \: y = 0 \: into \: equation \: 2

x = 6y + 7

x = 6(0) + 7

x = 0 + 7

x = 7

What is the product ? (Y^2 +3y +7) (8y^2 + y+1)
dmitriy555 [2]

Answer:

The answer is D

Step-by-step explanation:

When multiplied together, you get 8y^4+ y^3+ y^2+ 24y^3+ 3y^2+ 3y+ 56y^2+ 7y+ 7, which can be added up to get 8y^4+ 25y^3+ 60y^2+ 10y+ 7.

Tigers  <   Lions                          Lions  2

Lions< wolverines                      Panthers   0

Lions> Panthers                         Wolverines  1

Even though the lions scored more wolverines scored more than the panthers since the panthers didn't score a single point according to my calculations

There students Row every relationship between decimal, fraction, or percents.
ratelena [41]

Answer:

Answer is Lee Ann wrote the right equation.

Step-by-step explanation:

2/8 equals 25%, which equals 1/4, half of 25% is 12.5%, so 25% plus 12.5% equals 37.5%.

37.5% in decimal form is 0.375.

Therefore Lee Ann is correct.
