A. x ≥ -5 and x < 4

EXPLANATION

We have the two inequalities:

- 4x + 1 ≤ 21 and 5x + 2 < 22

Let us solve them separately:

FIRST ONE

-4x + 1 ≤ 21

Collect like terms:

-4x ≤ 21 - 1

-4x ≤ 20

Divide through by -4, the sign changes:

SECOND ONE

5x + 2 < 22

Collect like terms:

5x < 22 - 2

5x < 20

Divide through by 5:

x < 20 / 5

x < 4

The answer is Option A.

1. The timing shown in the morning is from 8:15 to 12:15, this is the number of hours worked in the morning is 4 hours.

The pay is $13.50 per hour

Therefore, the pay earned in the morning is:

then, the pay earned in the morning is $54

2. The timing shown in the afternoon is from 13:00 to 17:30, this is the number of hours worked in the afternoon is 4 hours and 30 minutes. Therefore, the pay in the afternoon is:

then, the pay earned in the afternoon is $60.75

The pay per 1 day is:

pay in the morning + pay in the afternoon

Answer: pay for a day is $114.75

Let

x -----> the number of milliliters of the 3.5% solution

y ----> the number of milliliters of the 6% solution

we have that

3.5%=3.5/100=0.035

6%=6/100=0.06

5%=5/100=0.05

so

0.035x+0.06y=0.05(500) -------> equation A

and

x+y=500 -----> x=500-y ------> equation B

solve the system of equations

substitute equation B in equation A

0.035(500-y)+0.06y=0.05(500)

solve for y

17.5-0.035y+0.06y=25

0.025y=25-17.5

0.025y=7.5

y=300

Find out the value of x

x=500-300=200

therefore

We will investigate how to graph a straight line on cartesian coordinate plane.

All equations of straight line are expressed in a general slope-intercept form as follows:

Where,

To graph any straight line we need the equation of the straight line or atleast two points that must lie on the line.

We are given the slope ( m ) and one of the points that lie on the line as follows:

We need one another point that lies on the line to plot the graph of a straight line. To find another point we must completely express the equation of the straight line ( general form given above ).

We see that an equation of a straight line is defined by two parameters i.e ( m and c ). We are given the value of the slope ( m ). We will go ahead and plug it into the general slope-intercept form given above:

Now to determine the value of parameter ( c ) we must have atleast one point that lies on the line. We will use the point given to us and plug in the respective coordinates in the equation developed above and solve for ( c ) as follows:

We will go ahead and update the equation of the straight line as follows:

Now to get one more point to graph the plot we will assume any value of the for either variable ( x or y ) and then determine the value of the other variable as follows:

Therefore, we have the two points to plot the graph as follows:

We can go ahead and select the above points on the given grid to construct the straight line!

To find the slope of the line that passes through (9, 10) and (6, 12)

We will use the formula;

From the points given;

x₁ = 9 y₁=10

x₂ = 6 y₂=12

Substitute the values into the formula;

Evaluate;

The room is a rectangle with dimensions 25 and x + 10. The area of a rectangle is the product of its dimensions, so the area will be:

We have to add the parenthesis because we first need to add 10 and x and then multiply. Distributing the 25, we have:

As we can see, this matches what Ron thinks the area will be, so he is correct. Thus, the answer is "Yes". The why can be both because the area is the sum of 25*10 and 25x and because the area is the product of 25 and 10 + x.

So, the correct alternatives are A and D.

After simplification the answer is 31.418 or 31.42

Define Radicals

The √ symbol that is used to denote square root or nth roots. Radical Expression - A radical expression is an expression containing a square root.

The given expression is,

2√6(√2 + 5)

First, open the brackets

2√6 * √2 + 5 * 2√6

we know, √6 = √3 * 2 = √3 * √2

so, 2√3 * √2  * √2 + 10√6

We didn't open the both √6 values it's because we want to remove  root from √2 so as we know √2 * √2 = 2

2√3 * 2 + 10 * √6

=> 4√3 + 10 * √6

Now, put the values of √3 = 1.732 and √6 = 2.449

=> 4 *  1.732 + 10 * 2.449

=> 6.928 + 24.49

=> 31.418 or 31.42

Therefore, the answer is 31.418 or 31.42

The mid-point of LP is 1.5.

Here we have to find the mid-point of the line LP

L is on -2 on the line and P is on 5.

To find the mid-point we have a formula:

mid-point = (b - a)/2

where a and b are two points between which we have to find the mid-point.

So, mid-point of LP = 5 - (-2) / 2

                                = 7/ 2

                               = 3.5

Now we have to find the value so we will subtract -2 with 3.5.

So the mid-point is 3.5 - 2= 1.5.

Therefore the mid-point of the line LP is 1.5.

The value of g(x) will be expressed as g(x) = (x + 5)

A function may be defined as an expression in which for one value of input variable x there is only one value of output variable y. The input variable is called as independent variable and output variable is called dependent variable. Composite functions are the functions which are written as combination of two functions. A function f(x) may be defined as composite function of another function g(x) when it can be written as either f(g(x)) or g(f(x)). We know that f(x) = x⁹ and the composite function H(x) = f(g(x)) = (x + 5)⁹. So, from this we can say that the function g(x) will be given as (x + 50 as we put (x + 5) as x in the function H(x).

The equation of the line that passes through the points ( -3,18 ) and ( 2,-7 ) is f(x) = -5x + 3.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the data in the question;

Point 1( -3,18 )

Point 2( 2, -7 )

First, we find the slope of the line.

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

m = ( -7 - 18 ) / ( 2 - (-3) )

m = ( -25 ) / ( 2 + 3 )

m = ( -25 ) / ( 5 )

m = -5

Next, next we find the y-intercept

y = mx + b

18 = (-5)(-3) + b

18 = 15 + b

b = 18 - 15

b = 3

Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.

y = mx + b

y = (-5)x + 3

y = -5x + 3

Therefore, the equation of the line is y = -5x + 3

Answer: 80

Step-by-step explanation:

You do 2 times= 8 and multiply 8 to the 5 white and black tiles which equals 40+40=80.

The total area for the parallelogram shaped tiles Felix needs to buy is 80cm² at the price of $40.

In calculating for the area of parallelogram, the base is multiplied by the height, as the same way for calculating the area of a rectangle.

Given that, the base of one parallelogram shaped tile is 4cm with height as 2cm.

Area of one parallelogram shaped tile = 4cm × 2cm

Area of one parallelogram shaped tile = 8cm²

Total area for the 5black and 5white tiles = 10 × 8cm²

Total area for the 5black and 5white tiles = 80cm²

Therefore, Felix needs to buy a total of 80cm² of 10 parallelogram shaped tiles.
