A)  The equation that represents the cost of a pair of swim trunks is;

2(s - 3) + s = 79

B) The cost of a pair of swim trunks is; $28.33

Algebraic word problems are defined as questions that require translation of sentences to equations, and thereafter solving those equations.

Let the cost of one pair of swim trucks be s.

We are told that Each beach towel costs $3 less than a pair of swim trunks. Thus;

Cost of each beach trunk = (s - 3)

Jarvis bought 2 beach towels and 3 pairs of swim trunks at a retail store. Thus, we have;

2(s - 3) + s = 79

2s - 6 + s = 79

3s = 79 + 6

3s = 85

s = 85/3

s = $28.33

Answer: 33 shares

Step-by-step explanation:

Amount invested in the company = $41.25

Price per share = $1 1/4 = $1.25

To calculate the amount of shares that Martha invested in the company will be:

= Amount invested in the company/Price per share

= $41.25/$1.25

= 33 shares

Martha invested 33 shares in the company.

Answer:

Length = 7 feet, and width is 3 feet.

Step-by-step explanation:

For the given rectangular door,

area = length x width

21 = length x width ................. 1

Also,

perimeter = 2 ( length + width)

20 = 2 ( length + width)

10 = length + width ............ 1

Given that the factors of 21 are required to get the are of the door.

Then, from equation 1;

21 = 7 x 3

And from equation 2;

10 = 7 + 3

So that, the length of the door is 7 feet and its width is 3 feet.

Answer:

  A.  Subtract 6 from the x value to get the y value.

Step-by-step explanation:

Sometimes, it works well to simply try the answers to see what works. Sometimes, it works better to use a point other than the first or second.

Using the last point (x, y) = (16, 10), we can try the rules:

  subtract 6 from x: 16 -6 = 10 . . . this rule works

  multiply by 1/2: 16×1/2 = 8, not 10 . . . doesn't work

  multiply by 1/4: 16×1/4 = 4, not 10 . . . doesn't work

  add 6 to x: 16 +6 = 22, not 10 . . . doesn't work

The only rule that works is ...

  Subtract 6 from the x value to get the y value.

Additional comments

You cannot always assume the table represents a linear function. In this case, all of the answer choices are linear functions, so that is a reasonable assumption. The x-values all have the same difference: 4. The y-values also all have the same difference: 4. So the slope of the line is 4/4 = 1, which tells you right away that "multiply by 1/2" and "multiply by 1/4" will be wrong.

The x-values are all greater than the y-values, so "add 6 to the x value" will not be correct. Since the slope is 1, the difference between x and y will be a constant, easily found from any table entry.

  y = x + b . . . . equation of a line with a slope of 1

  2 = 8 + b . . . . using the first table entry

  -6 = b . . . . . . . subtract 8

Then ...

  y = x - 6

Decimal Fraction

Answer:

864 is the answer

Answer:

75 cm

Step-by-step explanation:

the ratio of centimeter to miles is 2:10 or 1:5 (1 cm = 5 mi)

this ratio can be changed to a fraction (1/5)

so now we can set up this equation:

(1/5) = (x/375)

where x = cm on the map

if it makes it easier to understand:

(1cm/5mi) = (xcm/375mi)

now we solve for x:

375(1/5) = x

x = 375/5

x = 75 cm

Answer:

Option (C)

Step-by-step explanation:

Conjugate root theorem:

If (a - bi) is a root of a polynomial with real coefficients, then (a + bi) will be the other root.

By this theorem, if (3 - 2i) is one root of the quadratic function 'f', other root will be (3 + 2i).

Therefore, x = (3 + 2i) will be the other root.

Option (C) will be the answer.

Answer:

Domain: interval: [0,∞], Words: All real numbers greater than or equal to 0, Inequality: x≥0.

Range: interval: [0,∞], Words: All real numbers greater than or equal to 0, Inequality: y≥0.

The domain and range of the function shown is

domain  [tex]x\geq 0[/tex]

range [tex]y\geq 0[/tex]

Given :

The graph of  the area of a rectangle changes with the length if it’s width is fixed

We need to find out the domain and range from the given graph

Domain is the set of x values on the graph

We can say the graph starts at x=0  and it goes up to infinity

So, domain is [tex]x\geq 0[/tex]

Range is the set of y values for which the function defined

Range is the set of y values on graph

When we look at y values , the graph starts at y=0 and it goes up to infinity

So, range is [tex]y\geq 0[/tex]
