Answer:

16 subsets

Step-by-step explanation:

To know the number of subsets that the set have, we will have to find the power of the set.

Given the set a = ( a,b,c,d)

P(a) = 2^n where;

n is the total number of element in the set

n = 4

p(a) = 2^4

P(a) = 16

Hence the set has 16 subsets

Answer:

6

Step-by-step explanation:

4(6) - 7y = -18

24 - 7y = -18

-7y= -42

y= 6

Answer: y=6

Step-by-step explanation:

4(6)-7y=-18

24-7y=-18 subtract 24 on both sides

-7y=-42 **then divide -7 on both sides**

and the answer is y=6

Answer:

$55+$9x≥$199

You must work for at least 16 hours to be able to buy the bicycle.

Step-by-step explanation:

Let x represent the number of hours you need to work to buy the bicycle.

You already have $55.

⇒$55+ −−−−−≥ −−−−−

You also earn $9 per hour.

Algebraically, this can be written as 9x.

⇒$55+$9x≥ −−−−−

You need to earn at least $199 to buy the bicycle.

⇒$55+$9x≥$199

The ≥ sign is used because the left-hand side of the inequality must be "greater than or equal to" $199.

Let's find out how many hours you need to work to buy the bicycle.

Subtracting $55 from both sides of the inequality:

⇒$55−$55+9x≥$199−$55

⇒$9x≥$144

Dividing both sides by $9:

⇒$9x$9$=$144$9

∴x≥16

Therefore, you need to work at least 16 hours to afford the bicycle.

Answer:

C. y + 3 = ¼(x + 4)

Step-by-step explanation:

✔️Find the slope of the given line:

Slope = ∆y/∆x = -(4/1) = -4

The line that is perpendicular to the given line on the graph would have a slope that is the negative reciprocal of -4.

Thus, the slope of the line that is perpendicular to the line on the graph would be ¼.

m = ¼.

Since the line passes through (-4, -3), to write the equation in point-slope form, substitute a = -4, b = -3, and m = ¼ into y - b = m(x - a)

Thus:

y - (-3) = ¼(x - (-4))

y + 3 = ¼(x + 4)

Answer: last graph

Step-by-step explanation: Graphs of functions that are ODD, are symmetric about the origin.

Graphs of function that are EVEN, are symmetric about y-axis.

We need to figure out which one of the 4 are EVEN. So we take y-axis as the mirror and see both sides, LEFT and RIGHT and see i the points are symmetric or not.

Graph 1, 2, 3  ----  not symmetric about y-axis

Graph 4  -------  Definitely every point to left side of y-axis has a corresponding mirror point to the right of y-axis. So this is an EVEN FUNCTION.

Answer:

The polynomial -8x2 + 54x + 140 can be factored as (x + 2)(-8x + 70).

The factor (x + 2) represents the final price per hot dog after increasing it from the starting price of $2, where x is the number of $1 increases in price.

The factor (-8x + 70) represents the average number of hot dogs sold based on the price increase. For every $1 increase in price, the number of hot dogs sold declines by 8. So, if the price increases by x dollars, the number of hot dogs sold declines by 8x. Since the number of hot dogs sold without the price increase is 70, the number of hot dogs after a price increase is -8x + 70.

Answer:

15 customers were outside

Step-by-step explanation:

Represent customers inside with x and customers outside with y.

So, we have:

[tex]x = \frac{1}{3}y - 2[/tex] --- First Statement

[tex]x = 3[/tex] --- Second Statement

Required

Find y

Substitute 3 for x in [tex]x = \frac{1}{3}y - 2[/tex]

[tex]3 = \frac{1}{3}y - 2[/tex]

Add 2 to both sides

[tex]2 + 3 = \frac{1}{3}y - 2 + 2[/tex]

[tex]2 + 3 = \frac{1}{3}y[/tex]

[tex]5= \frac{1}{3}y[/tex]

Multiply both sides by 3

[tex]3 * 5= \frac{1}{3}y *3[/tex]

[tex]15 = y[/tex]

[tex]y = 15[/tex]

Hence; 15 customers were outside

Answer:

the additional info required is - the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle.

Step-by-step explanation:

As given , RST and angle TUR are right angles.

So the triangles are right angle triangles.

If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.

So, the additional info required is - the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle.

Answer:

21.67 hours/ week

Step-by-step explanation:

Given

[tex]Hours = 65[/tex]

[tex]Weeks = 3[/tex]

Required

Determine the rate

The rate is calculated using:

[tex]Rate = \frac{Hours}{Weeks}[/tex]

Substitute values for hours and week

[tex]Rate = \frac{65}{3}[/tex]

[tex]Rate = 21.67[/tex]

This implies that the rate is 21.67 hours/ week

Answer:

3/1

Step-by-step explanation:

Given the expression 6/4/2, we are to express as a single fraction.

6/4/2

= 6÷4/2

= 6×2/4

= 12/4

= 3/1

Hence the expression as a single fraction is 3/1

Answer:

-2a - 2b

Step-by-step explanation:

Question : (4a + b)-3(2a + b)

= 4a + b - 6a - 3b

= 4a - 6a + b - 3b

= -2a + (-2b)

= -2a -2b

If you need detail solution here ;

first + multiply both 4a and b

first -3 multiply both 2a and b and then -3×2a= -6a

-3×b = -3b

and it will be 4a + b -6a -3b,then collect like terms

4a - 6a + b -3b

= -2a +(-2b) in this part + tims - = -

= -2a - 2b

The triangles of the dimensions are not similar by any property of similarity. Thus option D is correct.

Concept of similarity : Two triangles can be similar by AAA, SAS, SSS property .

Given,

Two triangles with different side lengths.

Here,

The two triangles are similar if they have same shape , but can be of different sizes and corresponding sides are of same proportions.

Here,

Triangles are of same shape but the corresponding sides are not in same proportions.

∴ 8/5 = 10/6.25 ≠  12/7

Therefore the two triangles are not similar.
