What point is A and B? I’m unable to help without knowing context of the previous question that led to number 16.

1. −2x + 6 = -16
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

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]

Rewrite in simplified exponential notation
Helppp

Answers

Answer:

1/4096

Step-by-step explanation:

A negative exponent becomes a fraction. 4*3=12. 2^12=4096, so since it's a negative exponent you put it as a fraction. So it's 1/4096.

The simple exponential notation is 4,096.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The exponential notation is;

⇒ [tex](2^{-4} )^-^3[/tex]

Now, Solve the exponential notation as;

⇒ [tex](2^{-4} )^-^3[/tex] = [tex]2^{-4*-3}[/tex]

               = [tex]2^{12}[/tex]

               = [tex]4096[/tex]

Hence, The simple exponential notation is 4,096.

4x=3y-2 in slope intercept form
Explain

Answers

the answer is y = 4/3x + 2

Answer:

y = 1-1/3x + 2/3

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:

y = 1-1/3x + 2/3

Antoinette solves the linear equation 3 (x minus 3) + 2 x + 9 = 2 x + 2 (x minus 1) using the steps shown below.

Step 1: 3 x minus 3 + 2 x + 9 = 2 x + 2 (x minus 1)
Step 2: 5 x + 6 = 4 x minus 1
Step 3: 5 x minus 4 x = negative 1 minus 6
Step 4: x = negative 7
