how do i solve this step by step? i dont know how to set up this equation

Answer:

11x+11y-4

Step-by-step explanation:

The parabola crosses the x-axis at x = 1 and x = -3.

x - 1 = 0

x = 1

x + 3 = 0

x = -3

b = 3

You times (1) by 2 so that the y's are the same

You add (3) and (2) instead of subtracting them because the sign in front of thr 2y's are different; adding them will eliminate them

Answer:

17.156

Step-by-step explanation:

A rational number has has a terminating decimal expansion or a decimal expansion of non-terminating repeating digits. Here, the decimal expansion is terminating, so it is a rational number.

Answer:

C. 17.156

Step-by-step explanation:

A rational number is any number that can be expressed as a fraction. So for example, since [tex]\sqrt{2}[/tex] cant be expressed as a fraction, it isn't rational. A number like 1.25 on the other hand IS rational as it can be expressed as [tex]\frac{5}{4}[/tex] or [tex]\frac{125}{100}[/tex].

Option C can be expressed as [tex]\frac{17156}{1000}[/tex], so it must be rational.

- Note that if a number has a finite amount of digits after the decimal (ie it doesn't go on forever like option B), it can be represented as a fraction and thus is rational.

Step-by-step explanation:

to find the equation of a line having the slope use this formula:

[tex]y - yp = m(x - xp)[/tex]

in which:

- yp is the y of the point (so 4);

- m is the slope (so 5);

- xp is the x of the point (so -1)

so:

[tex]y - 4 = 5(x - ( - 1))[/tex]

[tex]y - 4 = 5x + 5[/tex]

[tex]y=5x + 5 + 4[/tex]

[tex]y = 5x + 9[/tex]

Answer

8/12=4/6=2/3

When simplifying, if both the numerator and the denominator are even you can just divide them by two

Based on the cost of the adult tickets and the children's ticket, the expression that can find the amount raised is 8x + 3y.

Also if those number of tickets were sold, the amount realized would be $3,054.

The total amount raised can be found as:

= (Number of adult tickets x price of adult tickets) + (Number of children's tickets x price of children's tickets)

Assuming the adult tickets are x and the children's tickets are y, the equation would be:

= (x × 8) + (y × 3)

= 8x + 3y

If 240 adult tickets and 378 children's tickets are sold, the amount realized would be:

= 8x + 3y

= (8 x 240) + (3 x 378)

= $3,054

In conclusion, the relevant expression is 8x + 3y and the amount raised would be $3,054.

[tex]\sf\longmapsto \: 3.73 hours [/tex]

Step-by-step explanation:

[tex]\sf\longmapsto \: \frac{1}{7 } + \frac{1}{8} [/tex]

[tex]\sf\longmapsto \: \frac{15}{56} [/tex]

Now, Reciprocal–

[tex]\sf\longmapsto \: \frac{56}{15} [/tex]

[tex]\sf\longmapsto \: 3.73 hours [/tex]

The time taken together Marie and his sister to paint the living room are 3.73 hours or 3 hours and 43.8 minutes.

Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.

Another illustration of labor is when you finish your meal in an hour, which means that you finished your work in an hour.

Given that,

Marie take 7 hours to paint

1 work → 7 hour

1 hour → (1/7) work

Barbara takes 8 hour

1 work → 8 hour

1 hour → (1/8) work

Let's suppose together they take x hour

1 work → x hour

1 hour → (1/x) work

Now,

1-hour work together = 1-hour work of Marie + 1-hour work of Barbara

(1/x) = (1/7) + (1/8)

(1/x) = (7 + 8)/56

x = 56/15

x = 3.73

x = 3 hour and 0.73 × 60 = 43.8 minutes.

Hence "The time taken together Marie and his sister to paint the living room is 3.73 hours or 3 hours and 43.8 minutes".

The probability that when a coin is tossed, the result is tails = 1/2

The probability that when a single six-sided die is rolled, the outcome is 1 = 1/6

The probability that when a six-sided die is rolled, the outcome is 13 = 0

Probability is simply how likely something is to happen.

A).

The probability that when a single six-sided die is rolled, the outcome is 1.

When a dice is thrown, sample space = {1, 2, 3, 4, 5, 6}

All six digits are equally likely to occur.

P (occurring 1) = 1/6

B).

The probability that when a six-sided die is rolled, the outcome is 13.

When a dice is thrown, sample space = {1, 2, 3, 4, 5, 6}

13 does not occur in the sample space.

P (occurring 13) = 0

C).

The probability that when a coin is tossed, the result is tails.

When a coin is thrown, sample space = {H, T}

Both head and tail are equally likely to occur.

P (tail) = 1/2
