Answer:

5:33 am

Step-by-step explanation:

You need to be at the airport at 7:30

Subtract 30 minutes for travel

7:30 -30 = 7:00

You need 1 hour and 27 minutes to get ready

Subtract 1 hour

7-1 =6:00 am

Subtract 27 minutes

6:00 am - 27 minutes

5: 60 - 27   ( Remember there are 60 minutes in 1 hour)

5:33 am

You need to get up at 5:33 am

Check

5:33 plus 1 hr 27 minutes = 7:00 am + 30 minutes travel = 7:30 am

Answer:

ED = 31

DT = 20

Step-by-step explanation:

m< ESD = 90-52=38°

the distance ED = 40×tan 38° = 31.25 = 31

ET = 40 x tan (90-38) = 40×tan 52°

= 51.19= 51

the distance DT = 51-31 = 20

Answer:

[tex]\text{C. }(5,2)[/tex]

Step-by-step explanation:

The x-coordinate vertex of a parabola in standard form [tex]ax^2+bx+c[/tex] is equal [tex]\frac{-b}{2a}[/tex].

In [tex]y=3x^2-30x+77[/tex], we have:

Therefore, the x-coordinate of the vertex is equal to [tex]\frac{-(-30)}{2(3)}=\frac{30}{6}=5[/tex].

To find the y-coordinate, simply substitute [tex]x=5[/tex] into the parabola's equation:

[tex]y=3x^2-30x+77,\\y=3(5^2)-30(5)+77,\\y=75-150+77,\\y=-75+77=2[/tex]

Thus, the vertex of the parabola is [tex]\boxed{(5,2)}[/tex]

Answer:

x = 1/4

y = -1/2

z = 9/4

Step-by-step explanation:

Here we have a system of 3 equations with 3 variables:

4*x + 2*y + 1 = 1

2*x - y = 1

x + 3*y + z = 1

The first step to solve this, is to isolate one of the variables in one of the equations, let's isolate "y" in the second equation:

2*x - y = 1

2*x - 1 = y

Now that we have an expression equivalent to "y", we can replace this in the other two equations:

4*x + 2*(2*x - 1) + 1 = 1

x + 3*(2*x - 1) + z = 1

Now let's simplify these two equations:

8*x - 1 = 1

7*x - 3 + z = 1

Now, in the first equation we have only the variable x, so we can solve that equation to find the value of x:

8*x - 1 = 1

8*x = 1 + 1 = 2

x = 2/8 = 1/4

Now that we know the value of x, we can replace this in the other equation to find the value of z.

7*(1/4) -3 + z = 1

7/4 - 3 + z = 1

z = 1 + 3 - 7/4

z = 4 - 7/4

z = 16/4 - 7/4 = 9/4

z = 9/4

Now we can use the equation y = 2*x - 1 and the value of x to find the value of y:

y = 2*(1/4) - 1

y = 2/4 - 1

y = 1/2 - 1

y = -1/2

Then the solution is:

x = 1/4

y = -1/2

z = 9/4

Answer:

Slope = -17

Step-by-step explanation:

We are given the equation of the line to be:

y = -17x + 47/3 which is in the slope-intercept form.

Recall: equation of a line in slope-intercept form takes the following format:

y = mx + b

Where,

m = slope of the line

b = y-intercept of the line

Thus, the slope of the line (m), y = -17x + 47/3 would be -17

Your welcome! :) Good luck!

The factorization of x² - 2x - 3 is  (x+1)(x-3).

The given quadratic equation is,

x² - 2x - 3

The definition of a quadratic as a second-degree polynomial equation demands that at least one squared term must be included. It also goes by the name quadratic equations. The quadratic equation has the following generic form:

ax² + bx + c = 0

Hence to factorize we can write the given quadratic equation as,

⇒ x² - 3x + x - 3

⇒ x(x-3) + (x - 3)

⇒ (x+1)(x-3)

Hence,

x² - 2x - 3 =  (x+1)(x-3)

Answer:

x = 12

Step-by-step explanation:

The sides are congruent

5x - 17 = 3x + 7

Subtract 3x from both sides

2x - 17 = 7

Add 17 to both sides

2x = 24

Divide both sides by 2

x = 12

Answer:

X=0.8

Step-by-step explanation:

First collect all the light terms '7' and '17' '-17+7=-10'

And '3x' and' 5x' '3x+5x=8x'

So if you put this as an equation you will have '8x=-10'

Next you do 8 divided -10

Then you get 0.8

Answer:

A = 0.25*j + 1

Step-by-step explanation:

The question presented here is an application of linear models. The $1 amount is fixed and does not depend on any factor such as the cups of orange juice sold.

Furthermore, we are informed that we earn $0.25 for every cup of orange juice sold. This means that we shall earn 0.25 j by selling  j cups of orange juice.

The variable total amount, A will thus depend on the fixed amount of $1 and the variable income 0.25 j.

The equation in two variables that will represent the total amount A (in dollars) you have after selling j cups of orange juice will thus be;

A = 0.25*j + 1

Answer:

  B.

Step-by-step explanation:

Use t=0 and t=2 and locate the graph with those two points on it. (We choose these because the horizontal grid is 2 years for each grid line.)

For t=0, C(0) = 50000(0.9^0) -2000 = 480000

For t=2, C(2) = 50000(0.9^2) -2000 = 40500 -2000 = 38500

The only graph that has y-intercept of 48000 and crosses (2, 38500) is the one shown in choice B.

Answer: A

Step-by-step explanation:

Answer:

The answer is B.

Step-by-step explanation:

The opposite of squared is square root, so you'll have to square root 192 and you'll get the answer 13.86.

The reason it is B, because the x could have been negative, when you're squaring a negative you get a positive. that's why B is the answer because we do not know if it's the negative or positive.
