Number the steps for balancing equations:
write an equation for the line that passes through the given points (-2,9) And (1 ,-3)
Answer:
Finding slope: y2-y1/x2-x1
3-9/1+2
=-6/2
Divide 2 from both
=-3/1 or -3
Slope= -3
Finding y-intercept= y=mx+b
Choose any point on the line to plug in the x and the y then plug in the slope.
I choose (1,3)
3=-3×1+b
3=-3+b
Add 3 to both sides
6=b
Y-intercept=6
Equation: y=-3x+6

Greetings.
The answer is x > 24.
Explanation:
Solving Inequality is almost the same as equation. However, you have to know one thing about solving an Inequality.
That is whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality.
[tex]-\frac{1}{2}x<-12[/tex]
Reminder that
[tex]-\frac{1}{2}x=-\frac{x}{2}[/tex]
We use negative x above 2 instead (Easier in solving)
[tex]-\frac{x}{2}<-12[/tex]
Then we move 2 to divide -12.
[tex]-x<-12(2)\\-x<-24[/tex]
Because the coefficient for x is in negative. We move -1 to divide -24 as we get 24 (Because negative divide negative = positive)
But remember that "whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality."
So we change from < to > instead.
[tex]x>24[/tex]

A supermarket had bags of red grapes for $13.00 for 5 bags. They also had bags of green grapes priced at $5.08 for 2
bags. Which type of grape is most expensive?
A They are both the same price
B Green grapes
Red grapes
Answer:
They were both the same price
Step-by-step explanation:
$13.00 divided by 5 is 2.6
$5.08 divided by 2 equals 2.54 and if you round, it equals 2.6
Describe the transformation of the graph y = (x)^3 + 6
The graph of y = x^3 + 6 is the result of shifting y = x^3 up 6 units
If f(x) = x^3, then g(x) = f(x) + 6 leads to g(x) = x^3+6.
The reason we shift up 6 is because we're adding 6 to the y coordinate.
Think of y = f(x), so f(x)+6 is the same as y+6.

Noah's brother sells cars and earns 4.5% commission. He sold a truck for $62,000. How much commission will his brother earn?
Answer:
the commission earn by his brother is $2,790
Step-by-step explanation:
The computation of the commission earn by his brother is as follows
= Selling price of the truck × commission percentage
= $62,000 × 4.5%
= $2,790
Hence, the commission earn by his brother is $2,790
We simply applied the above formula so that the correct value could come

A rectangular carpet has a perimeter of 244 inches. The length of the carpet is 90 inches more than the width. Determine the dimensions of the carpet by solving the equation 2w+2(w+90)=244, where w represents the carpet width.
Answer:
The dimensions of rectangle are:
Width = 16 inches
Length = 106 inches
Step-by-step explanation:
Perimeter of rectangle = 244 inches
Let Width of rectangle = w
Length of rectangle = w+90
We need to find the dimensions (length and width) of the carpet
The formula used will be: [tex]Perimeter=2(length+width)[/tex]
Putting values and making equation:
[tex]244=2w+2(w+90)\\Solving:\\244=2w+2w+180\\244=4w+180\\Switching\:sides\\4w+180=244\\Subtracting\:180\:from\:both\:sides\\4w=244-180\\4w=64\\Dividing\:both\:sides\:by\:4\\\frac{4w}{4} =\frac{64}{4}\\w=16[/tex]
So, we get w = 16
The width w = 16 inches
Now, finding length = w+ 90 = 16+90 = 106 inches
Therefore the dimensions of rectangle are:
Width = 16 inches
Length = 106 inches

2n + 3 = -3.2 what is the answer to n
Answer:n=-3.1
Step-by-step explanation:
2n + 3 = -3.2
Subtract 3 on both sides
2n+3-3=-3.2-3
2n=-6.2
Divide 2 on both sides
2n/2=-6.2/2
n=-3.1
Answer:
n= -3.1

Answer:
A is Phosphourous, B is Oxygen
Step-by-step explanation:
The highest boiling point on the chart is 280 which belongs to Phosphouors, meaning that it has the highest boiling point. If you count it out, -183 you'd have to add 183 to get to 0, with 184 you would have to minus 184 to get to 0. So therefore oxygen's boiling point is closer to iodine.

Explain how to find vertical and horizontal asymptotes of a rational
equation.
Answer:
Step-by-step explanation: If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0).
If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

Alexander is a stockbroker he earns 11% commission each week last week he sold $7000 worth of stocks how much did he make last week in commission if he averages the same amount each week how much did he make in commission in 2011
Answer:
the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively
Step-by-step explanation:
The computation of the amount that he makes last week and in the year 2011 is as follows:
= Sale value of the stocks × earning percentage × number of weeks in a year
= $7,000 × 11% × 52 weeks
= $40,040
hence, the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively
