Answer:

8) the ordered pair is a solution, 9) the ordered pair is not a solution

Step-by-step explanation:

8) if you plug in the values of x into the equation, which is 7, 7+9 equals to 16, which is the y value in the ordered pair

9) the same is for this question, if you plug in the x value into the equation, which is 5, 2(5)+8 is equal to 10+8 which is equal to 18. This isn't equal to the y value in the ordered pair

Answer:

8.) yes it is a solution because if plug in 7 for x and 16 for y you get 16=7+9 which equals 16

9.) No it is not a solutions because if you plug in 28 for y and 5 for x you 28=2(5)+8 and then when you multiply the 2 and the 5 you get 28=10+8 and 10+8 equals 18 and 28 and 18 are not equal

What value of Y makes the equation true ?

Answers

Answer:

y = -5/2 or -2.5

Step-by-step explanation:

3y + 4 = -y - 6

add y to both sides

4y + 4 = -6

subtract 4 from both sides

4y + 4 - 4 = - 6 - 4

4y = -6 - 4

4y = -10

divide both sides by 4

4y/4 = -10/4

y = -10/4

y = -5/2 or -2.5

6 - 3x = 2x - 24

Answers

Answer:

x=6

Step-by-step explanation:

rearrange terms, subtract 6 from both sides, simplify, subtract 2x from both sides, simplify, divide both sides by -5, and finally you get 6.

Answer:

x=6

Step-by-step explanation:

6 - 3x = 2x - 24

move the x together and the numbers together

REMEMBER: when you move a something from one side of the equation (not including multiplication and division) to the other, change the sign in-front of it (+ or -)

NOW CONTINUE WITH THE PROBLEM -->

-3x-2x = -24 - 6

now subtract,

-5x = -30

and divide -30 by -5

Since there are 2 negative numbers, the result would be positive -->

and for x, you would get:

Baylor is #3 with a win to loss ratio of 11-2 for this season while Taylor is #1 with their unbeaten 11-0. Texas hit 294 as a team while Baylor hit 233, Texas Longhorns so far is the best hitting team efficiency wise in the country with a score of .359. Baylor took the lead in the first two sets when they made their first o2 comeback ever since Nov 1st of 2017. Hannah Sedwick, #14 Setter, in Baylor to me, seems like a really focused player, they mentioned how she was out for most of the season due to a fracture in her leg but yet she seems so active and awake, all of the players put in an effort but Hannah actually commits. When blocking the ball, her entire body became stiff and she carried the win for her team. On the other team there's Yossiana Pressley, #32 Outside Hitter, on the Baylor Bears who had 29 kills in the first part, and I have to say she completely dominated Baylor's with her spikes. Nilani Iosia, #12 Libero, in the Texas Longhorn scored 15 digs and an excellent passing percentage while Lauren Harrison, #31 Outside Hitter, Baylor Bears was the second leading attacker in the first part. Another notable player is Jhenna Gabriel, #2 setter, in Texas Longhorns who is the reigning national player of the big 12 player of the year.The Texas Longhorns came through this game with a ratio of 3-2 remaining unbeaten for the 12th time in a row. In one play I remember Butler barely hit the ball over the net and scored. It wasn't such a critical play but it had strategy and reasoning behind it. While Baylor prepared for the worst by upgrading the offense, they left their defense bare. That's why I think it was smart how Butler quickly noticed that and surprised them. This team had a quick dynamic where they would hit the ball before the blockers could completely cover over the net. Somewhere in the beginning, I immediately had a feeling Taylors had something the Bears didnt which helped them stay unbeaten. Id say its how they made sure to make their hits clear so that it can go through the blockers, and they were very efficient with passing the ball to their hitters. They shouldve had a clearer touch with the ball as well even if they won, it looked like both teams couldnt block the ball most of the time.The losing team, Baylor Bears, was honestly close to Texas's score. I couldn't stop focusing on Yossiana Pressley in Baylor, she had perfect momentum and sharp reflexes. Not just because of her kills but I'd say she was the MVP player of this game. The team was always so supportive as well especially whenever a small mistake occurred like a foul for going over the line on a serve. I have to admit, most of their sets were average, and not to mention how their hitters would constantly hit out of the court. It seemed as if they were trying to get it to hit the net so Taylor's would have more difficulty blocking it, if that's the case then it's a very smart move, but otherwise, if they just happened to be lucky then I'd consider it a miracle. This team could always track the ball but when it came to controlling the ball, they were late and had bad momentum. The sad part is, the Baylor Bears are such a good team, I personally liked them more in the beginning where I saw more action, but whenever it came down to the ball constantly being passed back and forth it seemed as if they lost energy which to me, ultimately led to the downfall of their team.

Both have their advantages and disadvantages. Farmers' markets have fresh and local produce, and often you get a chance to meet the people who grow your food. This isn't the case with grocery stores, where you'll never get to meet the farmers. Grocery stores are starting to have more local products, though, and they have a better variety of goods. Another thing to consider is the setting itself. Farmers' markets are usually in more pleasant, open-air locations where there's often live music playing. Grocery stores, on the other hand, can be busy and uncomfortable if you don't like shopping. The pleasant atmosphere comes at a price, though, as your bill at a farmers' market is likely to be 25 percent more than at a grocery store. All in all, the freshness and quality of food is worth a little more money. Farmers' markets are the way to go. Thanks!! Best answer I promise brainliest Please help with spanish
