Which one is correct please help

Answer:

4 Soccer balls and 6 Basketballs

Step-by-step explanation:

You can solve this problem by setting up a system of equations. Letting x be Soccer balls and y be Basketballs. Remember, Money goes with, Money goes with Money, meaning that for this problem the first equation that can be made is $248 = $28y + $20x with Y being basketballs and x being soccerballs. Next is a little more difficult. You will be creating the equation y=3x-6 because it is 6 less than 3 times the amount of x or Soccer balls. From here you can plug in the equations into a graphing calculator and graph it and see where the two lines intersect. This would be at (4, 6). When I said to let x equal Soccer Balls and y equal basketballs that is where I got the 4 soccer balls and 6 basketballs.

Answer: 4/3

First, rewrite in slope-intercept form:

-3y=-5-4x

3y=5+4x

y=5/3+4/3x

y=4/3x+5/3

And so we can see that 4/3 is the slope of the equation.

Answer: for b: function one has a greater rate of change

Step-by-step explanation: sorry i don't know the first one

Answer:

a) -2 and 4, b) function 2

Step-by-step explanation:

Rate of change is the same thing as slope. For the first function, the table, we can use two of the points and the slope formula. I'll use (-1,3) and (-2,5). Remember the slope formula:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Plug the points in:

[tex]m=\frac{5-3}{-2-(-1)}\\m=\frac{2}{-1}\\m=-2[/tex]

(Remember that subtracting a negative = adding. I look at it like the two 'minus' signs form one plus sign, if that helps)

So the slope of function 1 is -2.

We can do the same thing with the second function. Two points that I notice on the graph are (-1,0) and (0,4). Let's use the same slope formula.

[tex]m=\frac{4-0}{0-(-1)}\\m=\frac{4}{1}\\m=4[/tex]

And the slope of function 2 is 4. That answers the first part. The second part asks about rate of change.

Function 2 has a greater rate of change, since 4>-2.

Hope this helps!

Step-by-step explanation:

(tip)4.183+(tax)4.7808=8.9638 (this is the tip and tax)

59.76+8.9638=68.7238

You can include the thousandth but some school don't use that so you could put 4.781 for tax and 8.964 for tip and tax sum and for the total of everything 68.724

Answer:

The required inequality is:

[tex]\mathbf{x >60\: and\: x<135}[/tex]

Step-by-step explanation:

Minimum Money students should bring = $60

Maximum Money students should bring= $135

We need to write compound inequality  that  represents the amounts of money a student can bring.

Compound inequalities are combination of two inequalities combined with "and" , and "or"

And is used, when both inequalities should be true.

Or is used when one of the inequality should be true.

In our case we would use and because we need  both inequalities to be true.

The required inequality is:

[tex]\mathbf{x >60\: and\: x<135}[/tex]

Step-by-step explanation:

Answer:

The price of each CD before tax is $15.70

Step-by-step explanation:

Given that:

Number of CDs bought by Reuben = 5

Cost of five CDs = $81.50

Sales tax on each CD = $0.60

Sales tax on 5 CDs = 0.60*5 = $3.00

Price of CDs without tax = 81.50 - 3.00 = $78.50

Price of each CD = [tex]\frac{Cost\ of\ CDs}{No.\ of\ CDs}[/tex]

Price of each CD = [tex]\frac{78.50}{5}[/tex]

Price of each CD = $15.70

Hence,

The price of each CD before sales tax is $15.70

The equation of the line in slope-intercept form is:

Step-by-step explanation:

Given the points

Finding the slope

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-8,\:5\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-5\right)[/tex]

[tex]m=\frac{-5-5}{-1-\left(-8\right)}[/tex]

[tex]m=-\frac{10}{7}[/tex]

We know the slope-intercept form of the line equation is

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

substituting m = -10/7 and (-8, 5) in the slope-intercept form to determine the y-intercept

[tex]5\:=\:\frac{-10}{7}\left(-8\right)+b[/tex]

[tex]\frac{80}{7}+b=5[/tex]

[tex]b=-\frac{45}{7}[/tex]

now substituting m = -10/7 and b = -45/7 in the slope-intercept form

[tex]y = mx+b[/tex]

[tex]y\:=\:\frac{-10}{7}x+\left(-\frac{45}{7}\right)[/tex]

[tex]y\:=\:\frac{-10}{7}x-\frac{45}{7}[/tex]

Thus, the equation of the line in slope-intercept form is:

Answer:

44

Step-by-step explanation:

This is called the Tribonacci sequence. In this sequence, you add the last 3 numbers together to get the next number in the sequence.

For example, 0+1+1=2, 1+2+4=7, 4+7+13=24 and so on.

7+13+24=44

44 is the next number in the sequence

Answer:

I think the school is located at (0,4).

Step-by-step explanation:

I graphed the equation in my graphing calculator and it came up with a kind of v shaped graph. If you look at the question and see that we first house to school, that would probably mean from the left side of the graph to the center (0,4). Then we go from school to friend's house, so it must be from the center to the right side of the graph. Therefore, the school must be the y intercept (0,4) as that is the center of the graph.

Answer:

A. y = -1/4x + 1 1/2

B. The rate of change is losing/decreasing -1/4 (y axis unit) per (x axis unit)

Step-by-step explanation:

A. Your equation is 2x + 8y = 12

so solve this for y like any other other question. Start by subtracting 2x from both sides: 8y = -2x + 12

then divide both sides by 8 to isolate y: y = -2/8x + 12/8

simplify your equation: y = -1/4x + 3/2

turn 3/2 into a mixed fraction: y = -1/4x + 1 1/2

B. The rate of change is the same thing as the slope but you say it with units. I cant see a scenario but you can say something like:

The rate of change is losing/decreasing -1/4 (y axis unit) per (x axis unit)
