Answer:

II. One and only one solution

Step-by-step explanation:

Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One and only one solution. III. Many solutions.

Let assume the equation is given as;

x + 3y = 11 .... 1

x - y = -1 ....2

Using elimination method

Subtract equation 1 from 2

(x-x) + 3y-y = 11-(-1)

0+2y = 11+1

2y = 12

y = 12/2

y = 6

Substitute y = 6 into equation 2:

x-y = -1

x - 6 = -1

x = -1 + 6

x = 5

Hence the solution (x, y) is (5, 6)

Hence we can say the equation has One and only one solution since we have just a value for x and y

Answer:

[tex] 1\frac{1}{6} [/tex]

Step-by-step explanation:

Given:

[tex] \frac{2}{3}*1\frac{3}{4} [/tex]

Required:

Evaluate

SOLUTION:

To evaluate, we need to convert the mixed fraction to improper fraction, then multiply both fractions together.

Thus:

[tex] \frac{2}{3}*\frac{7}{4} [/tex]

Multiply the numerators together, and multiply the denominators together

[tex] = \frac{2 \times 7}{3 \times 4} [/tex]

[tex] = \frac{14}{12} [/tex]

Simply the fraction by dividing the numerator and denominator by 2

[tex] = \frac{7}{6} [/tex]

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

Answer:

32ounces I think

Step-by-step explanation:

Given:

The table of values.

To find:

The average rate of change for the given function from x = −1 to x = 2.

Solution:

From the given table it is clear that y=-3 at x=-1 and y=3 at x=2.

Formula for average rate of change is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Using the above formula, the average rate of change for the given function from x = −1 to x = 2 is

[tex]m=\dfrac{3-(-3)}{2-(-1)}[/tex]

[tex]m=\dfrac{3+3}{2+1}[/tex]

[tex]m=\dfrac{6}{3}[/tex]

[tex]m=2[/tex]

Therefore, the correct option is D.

Answer:

new area = 7m (length) x 4m (width) = 28; an increase of 12 sq meters

Step-by-step explanation:

Original area must have been 16 because both the length and width were 6 meters.

175% of 16 is 12, meaning the length must be increased from 4 to 7 to get 28 when multiplied by a width of 4m

Answer:

a. [tex] \frac{2}{3} [/tex]

Step-by-step explanation:

The fraction, [tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex] and less than [tex] \frac{3}{4} [/tex].

How do we know this? See below how the fractions are compared together.

First, compare [tex] \frac{2}{3} [/tex] and [tex] \frac{1}{2} [/tex].

Find a common denominator for both fractions:

Common denominator of 2 and 3 would be 6. Therefore, multiply as follows:

[tex] \frac{2 \times 2}{3 \times 2} = \frac{4}{6}[/tex] and

[tex] \frac{1 \times 3}{2 \times 3} = \frac{3}{6} [/tex].

Compare the numerators. Which one is greater?

Form the calculation above:

[tex] \frac{2}{3} = \frac{4}{6} [/tex] has a numerator of 4.

.

[tex] \frac{1}{2} = \frac{3}{6} [/tex] has a numerator of 3.

Since 4 is greater than 3, therefore, the fraction, [tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex].

✍️Compare [tex] \frac{2}{3} [/tex] and [tex] \frac{3}{4} [/tex].

Find a common denominator for both fractions

[tex] \frac{2 \times 4}{3 \times 4} = \frac{8}{12} [/tex] and

[tex] \frac{3 \times 3}{4 \times 3} = \frac{9}{12} [/tex]

Comparing their numerator, 8 is less than 9, therefore:

[tex] \frac{2}{3} [/tex] is less than [tex] \frac{3}{4} [/tex].

✔️We can conclude that:

[tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex], and less than [tex] \frac{3}{4} [/tex].

A mixed number to an improper fraction by multiplying the denominator of the fraction by the whole number and then adding the numerator

What are Mixed Numbers?

A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.

To convert a mixed number to an improper fraction , we need to follow these three steps :

Step 1 : Multiply the whole number by the denominator

Step 2 : Add the answer from Step 1 to the numerator

Step 3 : Write answer from Step 2 over the denominator

Take for example :

Let the number be x = 5 5/9

Step 1 :

Multiply the whole number by the denominator

9 × 5 = 45

Step 2 :

Add the answer from Step 1 to the numerator

45 + 5 = 50

Step 3 :

Write answer from Step 2 over the denominator

50/9

Therefore , the mixed number 5 5/9 is converted to its improper fraction as 50/9

Step-by-step explanation:

Answer:

A. 100 miles divide 2.5 hours = 40 miles per hour

The angle of rotation to map A into C is 180°.

The rotation is around the center of the square. Let's assume that the center coincides with the origin of a coordinate axis.

Then we would have A on the second quadrant and C on the fourth quadrant.

Then we need to apply a rotation of two quadrants, remember that each quadrant has an angle of 90°, then a rotation of two quadrants has an angle of 2*90° = 180°.

The correct option is 180°.

Which of the 4 has the greatest rate of change

For Graph (A):

We start by picking any two equivalent points on the table:

[tex](x_1,y_1) = (0,1)[/tex]

[tex](x_2,y_2) = (2,5)[/tex]

Next, we determine the slope, m:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{5-1}{2-0}[/tex]

[tex]m = \frac{4}{2}[/tex]

[tex]m = 2[/tex]

This represents the rate of change:

For (B): [tex]y = 3x + 7[/tex]

An equation is of the form:

[tex]y = mx + b[/tex]

Where

m represents slope or rate of change:

By comparison:

[tex]m = 3[/tex]

For table (C):

We start by picking any two equivalent points on the table:

[tex](x_1,y_1) = (1,7)[/tex]

[tex](x_2,y_2) = (2,12)[/tex]

Next, we determine the slope, m:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{12-7}{2-1}[/tex]

[tex]m = \frac{5}{1}[/tex]

[tex]m = 5[/tex]

This represents the rate of change:

For (D):

The $1.00 paid every week represents the rate of change.

So:

[tex]m = 1[/tex]

For A - D:

The rate of change are:

[tex]A = 2[/tex]

[tex]B = 3[/tex]

[tex]C = 5[/tex]

[tex]D = 1[/tex]

5 is the greatest.

Hence, (c) has the greatest rate of change
