4x + 2(x + 6). What is the simplified expression

Answer:

A

Step-by-step explanation:

Heya!

So the key is at the top. What I mean by the Key is a=1 b=2 c=3 d=4 e=5 and f=0. You use those numbers and plug them into the associated letters in the problems below. For example, question one with the numbers in it would be, (I might be wrong on this, I apologize)

[tex] \frac{0 + 3^{2} - 2 }{0 - 3} [/tex]

You would then solve the equation, and whatever answer you get for that equation would go with the corresponding numbers and letters on the left.

So for example, if your answer to the first one for example is 7, you would type A. You would then do the same for question 2, 3, and 4, which should reveal the four letter code for you to continue :))

Hope this helped!!

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:

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]

Question 3:

You have 1,450 marbles. You find 100 more.

1,450 + 100 = 1,550

You go and buy double of what you have.

1,550 x 2 = 3,100

Step-by-step explanation:

First step is to identify what the problem is asking for and what is given.

9 laps in 28 minutes

Searching for number of laps in 1 hour and 15 min.

1 hour + 15 min. = 75 minutes convert to minutes

9 laps / 28 minutes = x laps / 75 minutes create an equation

9/28 = x/75

9*75 = 28x cross multiply

675 = 28x

x = 675/28 = 24.12 simplify

Melanie can run 24 complete laps in 1 hour and 15 minutes.

Step-by-step explanat ez

5Answer:

Step-by-step explanation:

 Let the first session be y =20 + 30x .................. equation 1

 Let the second session be y = 10 + 35x .............. equation 2

equate the two functions

20 + 30x = 10 + 35x

y = 20 - 10 +30x - 35x

y = 10 -5x

Find the y intercept (that is where y = 0)

10-5x = 0

5x =10

x = 2

substitute x = 2 into equation 1 and 2

y =20 + 30(2) = 80

y = 10 + 35(2) =80

Notice that when you plot the graph for equ. 1 and equ. 2 , it intercepts at x =2 and y =80 (2, 80)

Answer:

126mm

Step-by-step explanation:

To find the diameter of the circle = circumference divided by pi = 56.52/3.14=18mm.

There are 4 circles = 18mmx4=72mm

Add on the 3x strips = 72+(18x3) = 126mm.

1) The equation that has infinitely many solution is y = -8/11·x + 4

2) The equation of the graph that has no solution is y = -8/11·x + 1

3) The equation of the line that has only one solution is y = -1/4·x + 2

Step-by-step explanation:

1) The points on the graph are;

(0, 4), and (5.5, 0)

The slope of the line defined by the given two points, we have;

(0 - 4)/(5.5 - 0) = -40/55 = -8/11

the equation of the straight line graph in point and slope form, we have;

y - 4 = -8/11 × (x - 0)

y - 4 = -8/11·x

For the equation for the system that has infinitely many solution, we have;

y = -8/11·x + 4

2) For the equation whose graph foes through the point (0, 1) and the system has no solution, we have;

An equation that has no solution with the equation y = -8/11·x + 4, is parallel to y = -8/11·x + 4, and therefore, the slope are equal

Therefore, the equation whose graph foes through the point (0, 1) and the system has no solution, in point and slope form is given as follows;

y - 1 = -8/11 × (x - 0)

y - 1 = -8/11·x

The equation of the graph that has no solution is therefore;

y = -8/11·x + 1

3) For the equation of the graph that goes through the point (0, 2), and has a common solution with the system at (4, 1), we have;

The slope of the graph is (1 - 2)/(4 - 0) = -1/4

The equation of the line that has only one solution with the system in point and slope form is given as follows;

y - 2 = -1/4×(x - 0)

y - 2 = -1/4·x

The equation of the line that has only one solution in standard form is therefore;

y = -1/4·x + 2

The second equation for the system so it has infinitely many solutions is [tex]y=-\dfrac{3}{4}x+1[/tex] and the second equation whose graph goes through (0,2) so the system has one solution at (4,1) is [tex]\rm y = -\dfrac{1}{4}x+2[/tex] and this can be determined by using the point-slope form of the line.

Given :

The graph of the line that passes through the points (4,1) and (0,4).

The equation of the line that passes through the points (4,1) and (0,4) is given by:

[tex]\dfrac{y-1}{x-4}=\dfrac{4-1}{0-4}[/tex]

Cross multiply in the above equation.

-4(y - 1) = 3(x - 4)

-4y + 4 = 3x - 12

3x + 4y = 16

[tex]\rm y = 4-\dfrac{3x}{4}[/tex]   --- (1)

a) The second equation for the system so it has infinitely many solutions is given by:

Multiply equation (1) by 2 in order to determine the second equation.

[tex]\rm 2\times \left(y = 4-\dfrac{3x}{4}\right)[/tex]

[tex]\rm 2y = 8 - \dfrac{3x}{2}[/tex]

b) The second equation that passes through (0,1) and has a slope of -3/4 is given by:

[tex](y-1)=-\dfrac{3}{4}(x)[/tex]

[tex]y=-\dfrac{3}{4}x+1[/tex]

c) The second equation whose graph goes through (0,2) so the system has one solution at (4,1) is given by:

[tex]\dfrac{y - 2}{x-0}=\dfrac{1-2}{4-0}[/tex]

Cross multiply in the above equation.

4(y - 2) = -1(x)

4y - 8 = -x

[tex]\rm y = -\dfrac{1}{4}x+2[/tex]
