The sketches are illustrations of inequalities

  • <em>The first sketch is: </em>-2 \le x \le 5<em>.</em>
  • <em>The second sketch is: </em>3 \ge x \ge -4<em />

<em />

<u />

<u>Sketch A</u>

In sketch A, we have the following observations:

  • <em>The arrow faces left (this implies less than)</em>
  • <em>The dots on -2 and -5 are closed dots (this implies less than or equal to).</em>

<em />

Hence, the inequality is:

-2 \le x \le 5

<u />

<u>Sketch B</u>

In sketch B, we have the following observations:

  • <em>The arrow faces right (this implies greater than)</em>
  • <em>The dots on -4 and 3 are closed dots (this implies greater than or equal to).</em>

<em />

Hence, the inequality is:

3 \ge x \ge -4

7. Sapna travelled 48 km to meet her parents. She travelled the first 18 km by car and the remaining distance by train. Find the
Anton [14]

The fraction of the journey Sapna traveled by car and train is 3/8 and 5/8 respectively.

We know that fraction is an expression in mathematics used to denote the division of two whole numbers.

Given that the total distance = 48 km.

The distance Sapna traveled by car = 18 km.

So, the fraction is = distance traveled by car/total distance = 18/48 = 3/8

The distance Sapna traveled by train = 48 - 18 km = 30 km.

So, the fraction is = distance traveled by train/total distance = 30/48 = 5/8

Therefore the fraction of the journey Sapna traveled by car and train is 3/8 and 5/8 respectively.

Adam exchanged British pounds for Swiss franc He changed £400 into 592 francs What was the exchange rate of British pounds to Sw
OLEGan [10]

Answer: 1 : 1.48

Step-by-step explanation:

Adam was able to change £400 into 592 francs which means that the British pound is stronger because it was able to buy more Swiss francs.

The exchange rate can be gotten using direct proportion:

400 : 592

1       : x

Cross multiply:

400x = 592

x = 592/400

x = 1.48

Exchange rate is:

= 1 : 1.48

QRST is a parallelogram. Find x and y.
Wewaii [24]

In parallelograms, opposite sides are congruent, meaning that they are the same lengths. So, we have:

y - 4x = 9

-x + 4 = y

Add x to both sides of the second equation:

y + x = 4

y - 4x = 9

This is a system of linear equations. Solve by eliminating the y and subtracting the two equations:

5x = -5

x = -1

Use x to solve for y:

y + (-1) = 4

y = 5

So, x = -1 and y = 5.

Graph the equation <br><br> y≥-4/3x-7
True [87]

Answer: See picture

Step-by-step explanation:

For this problem, we need to know how to graph the inequality. First, let's establish that we will have a solid line because the inequality is greater than or equal to. If the inequality was only greater than, then it would be a dotted line. For -4/3x-7, you would start at (0,-7) as the y-intercept. Then you would go down by 4 and go to the right by 3 units. Now, we have to do shading. Since we know that y is greater than or equal to, the shading will be on top of the line, where y is greater.
