4- (-4) = 8       or:   4 +4 = 8

Step-by-step explanation:

subtracting a negative, is the same thing as adding a positive. so whenever you see a subtraction sign along with a number in parenthesis that has a negative sign, you add the numbers together

Find the equation of the linear function represented by the table below in slope- intercept form. х: -2, 2, 6, 10 y: -5, 7, 19, 31​

Answers

Answer:

y = 3x + 1

Step-by-step explanation:

Slope-intercept form is y = mx + b.

To find the slope (m), you use the equation (y1-y2)/(x1-x2). Plug in your points (-2, -5) and (2, 7) to get (-5 - 7)/(-2 - 2). Simplify the formula to get a slope of 3. This is your variable m.

To get the entire equation, finding b in the process, you use the formula y - y1 = m(x - x1). Replace m with 3. Using the point (-2, -5), replace it with (x1, y1) respectively to get y + 5 = 3(x + 2). Distribute to get y + 5 = 3x + 6. Isolate the y to get your final answer: y = 3x + 1.

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

3x - 6 = 9

Step 2: Solve for x

Add 6 to both sides:                    3x = 15Divide 3 on both sides:                x = 5

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    3(5) - 6 = 9Multiply:                               15 - 6 = 9Subtract:                              9 = 9

Here we see that 9 does indeed equal 9.

∴ x = 5 is the solution to the equation.

Ducklings cost $15 each. Chicks cost $12 each. You have $60 to spend on poultry

Answers

Answer:

If your question is how much money you have after you purchase a duckling and a chick, your answer would be $33. It seems to me like you posted the question without finishing it. I'm guessing you were about to mention how many ducklings and chicks you were going to buy and how much money you would have leftover for the poultry.

Step-by-step explanation:

To solve your problem you must add what you're buying and then subtract from your original amount.

For example: if you want one duckling and one chick and you would like to know how much money you have leftover to buy poultry. $15 + $12= $27 dollars in all. Then, you will subtract $27 dollars from $60, this way you know how much money you will have left in order to buy the poultry. $60 - $27= $33.

What is the value of this function evaluated at f(-3): f(x) = 2x2+ 5x - 9? F -6 G -42 H 42 J 12

Answers

Answer:

f(-3) = -6

Step-by-step explanation:

f(x) = 2x^2+ 5x - 9

We are to find f(-3)

f(-3) = 2(-3)^2+ 5(-3) - 9

f(-3) = 2(9)-15 - 9

f(-3) = 18 -15 -9

f(-3) = 18-24

f(-3) = -6

A peach pie is made with 13 peaches, which are evenly distributed throughout the pie. If Joe ate one slice of pie that contained exactly 5 peaches, what wqs the angle measure of the slice to the nearest tenth of a degree?

Answers

Answer:

138.5°

Step-by-step explanation:

A peach pie is in the form of a circle. The sum of angles in a pie is equal to 360°.

Since there are 13 peaches evenly distributed, therefore each peach occupies 360/13 degrees.

Joe ate one slice of pie that contained exactly 5 peaches, hence:

Angle measure of slice = (number of peaches in the slice / total number of peaches) * 360°

Angle measure of slice = (5 / 13) * 360°

Angle measure of slice = 138.5°

Which function is best represented by the graph?

Answers

Answer:

J

Step-by-step explanation:

First look at the y-intercept. When y=0, you get 8 on the graph, so in the equation it has to give you 8 as well.

This narrows it down to F G J

Next, the slope of the graph is negative because its tilting downwards.

This narrows it down to G J

Finally, on the graph when y=0, you get 6, so the equation has to meet this too

With your choices narrowed down to G and J, calculate the x-intercepts.

0= -4/3x+8

-8= -4/3x

-8(-3/4)=x

x=6

Answer:

The answer is J

Step-by-step explanation:

the y-intercept is 8 and to find the slope you count rise over run, well the graph is too small to tell what points are actually on the lines, but it's given that (0,8) and (6,0) are points. making the rise/run= to 8/6 and then simplify to 4/3. and you can tell that the slope is negative because it's going downward from left to right.

I'm not good at determining what is happening in a volleyball game. So if you can understand what I'm describing in this essay, the information I'm saying is relevant, and you actually understand how volleyball works, can you please tell me if this is good? Any negative comments are helpful.The team's playing in this video are presented as Baylor Bears and Texas Longhorns. 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.
