Brayden is working two summer jobs, making $21 per hour tutoring and making $10 per hour landscaping. In a given week, he can work a maximum of 12 total hours and must earn no less than $170. If xx represents the number of hours tutoring and yy represents the number of hours landscaping, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Answer:

2 hours.

Step-by-step explanation:

Money earned for 14 hours of life-guarding = 14*18 = $252.  If he worked another 5 hours  to make the maximum of 19 he would earn 252 + 5*9

= $297  but he wants to work a minimum of hours for  a minimum of 270.

Thus we have the inequality:

252 + 9x ≤ 270

9x  ≤  18

x  ≤ 2.

So the number of hours he must do clearing tables = 2.

Answer:

The set of two or more inequalities in one or more variables is referred to as a system of inequalities, and the further discussion can be defined as follows:

System of inequalities:

Get y alone on one side of a linear inequality with 2 variables (x,y). Consider the equation that results when the inequality sign is changed to an equality sign. This equation has a line as its graph. A dashed line is drawn if the inequality is strict.

From the question, we know

[tex]21 x+10y \geq 170[/tex]  money

[tex]x+y \leq 12[/tex]           hours

so

Inequality [tex]1 : y\geq - \frac{21}{10} x+17\\\\[/tex]

Inequality [tex]2 : y\leq -x+12\\\\[/tex]

and [tex]x=0, y= 0[/tex]

For example

[tex]y = 2 \ \ \ x=10[/tex]

2. -10 + 5x = -45
Can you help me?

Answers

I just know that 2 is X = 6

Answer:

for the first one, it's x=11. first, you have to subtract 6 from both sides (-2x+6-6=-16-6) then you simplify that so you get -2x=-22, and from there you divide both sides by -2

getting -2x/-2=-22/-2 then you simplify that and get x=11

and for the second one x=-7. first, you have to add 10 to both sides

(-10+5x+10=-45+10) then simplify that down to 5x=-35 then divide both sides by 5 (5x/5=-35/5) then simplify that down to x=-7

x + 4 5/6 = 9 what is x

Answers

x+29/6=9
(convert mixed fraction to improper)
x=9-29/6
x=25/6 (calculate the difference)
therefore your answer is x=25/6
or x=4 1/6 OR x= 4.16

The value of x from the given equation is [tex]4\frac{1}{6}[/tex] .

The given equation is [tex]x+4\frac{5}{6} =9[/tex].

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Here, the given equation can be written as x+29/6 = 9

x = 9-29/6

x = (54-29)/6

x = 25/6

x = [tex]4\frac{1}{6}[/tex]

Therefore, the value of x from the given equation is [tex]4\frac{1}{6}[/tex] .

Answer:

Step-by-step explanation:

Slope-intercept form is y=mx+b

Subtract 3y from both sides to move it to the left side. You now have:

-3y + 4x = -2

Subtract 4x from both sides to move it to the right side. You now have:

-3y = -4x -2

Divide by -3 to get y alone:
