Answer:

Step-by-step explanation:

5 2/5 = [(5*5)]+2 / 5 = (25+2) / 5 = 27/5

(27/5)/(9/10) = 27/5 * 10/9

cross cancel 27 becomes 3 and 9 becomes 1, 5 becomes 1 and 10 becomes 2

= 3/1 * 2/1 = 6/1 = 6

Answer:

(2,-4)

Step-by-step explanation:

(2,4) is located in Quadrent I (+,+), if you reflect over the x-axis, it would be in Quadrent IV (+,-).

if you dont understand I suggest you draw a coordinate plane on a graphing notebook.

Answer:

4t + 12 [tex]\leq[/tex] 80

Step-by-step explanation:

Set up an inequality where t is the cost of one ticket

Since her budget is $80, a less than or equal sign needs to be used.

4t will represent the total cost of the tickets, since she needs to buy 4. Add 12 to this to represent the parking cost:

4t + 12 [tex]\leq[/tex] 80 is the inequality.

Answer:

9/2

Step-by-step explanation:

3/4 x 6 can be thought of as multiplying 3/4 x 6/1

When multiplying fractions, multiply the numerator (top number) with the numerator, and the denominator with the denominator.

3/4 x 6/1 = (3x6)/(4x1)

3/4 x 6/1 = (18)/(4)

3/4 x 6/1 = 9/2

Let me know if this helps!

Answer:

  the correct choices are shown

Step-by-step explanation:

Statement . . . . . Reason

1. c ║ d; ∠4 = ∠5 . . . . . Given

2. ∠4 = ∠7 . . . . . Alternate interior angles are equal

3. ∠5 = ∠8 . . . . . Vertical angles are equal

4. ∠7 = ∠8 . . . . . Substitution

Answer:

-27

Step-by-step explanation:

8x - 6 - 7y + 3

X = 3 Y = 6

8(3) - 6 - 7(6) + 3

8 x 3 = 24

7 x 6 = 42

24 - 6 - (42 + 3)

(24 - 6) - 45

18 - 45 = -27

1. $65,000

2. A 4 and 2 mile hike

3. B 4.00

4. C multiplication

Step-by-step explanation:

Answer:

6.47secs

Step-by-step explanation:

Given the height of the rocket modelled by the equation;

h = – 16t^2 + 102t + 10, where ‘t' is the time in seconds

The rocket will hit the ground at h = 0

Substitute into the equation

– 16t^2 + 102t + 10 = 0

Multiply through by -1

16t^2-102t-10 = 0

t = 102±√(102)²-4(16)(-10)/2(16)

t = 102±√10404+640/32

t = 102±√11044/32

t = 102 ±105.09/32

t = 102+105.09/32

t = 207.09/32

t = 6.47secs

Hence it will take 6.47secs for the rocket to hit the ground

Answer:

slope is 5/2

Step-by-step explanation:

5 over 2

Answer:

Step-by-step explanation:

Given the coordinates (4, -2) and (24, -17), we are to find the slope of the line passing through the points

Slope = y2-y1/x2-x1

Slope = -17-(-2)/24-4

Slope = -17+2/20

Slope = -15/20

Slope = -3/4

Hence the required slope is -3/4

Answer:

That smile tho lol

anywayssssss

b= 16 mm

Step-by-step explanation:

Pythagorean theorem is a^2 + b^2= c^2, so-

12^2 +b^2= 20^2

144+b^2=400

b^2=400-144

b^2= 256

b= 16

Answer:

16 mm

Step-by-step explanation:

A²+B²=C²

12²+x²=20²

144+x²=400

x²=400-144

x²=256

√x = √256

x = 16

Answer:

D

Step-by-step explanation:

Step-by-step explanation:

f(x) = x + 3/ 2

For a

f(2) = 2 + 3 / 2

= ( 4 + 3 ) /2

= 7/2

For b

f(x) = x + 3/2

f^-1(x) = ?

Let y = f(x)

y = x + 3/2

Interchanging the roles of x and y we get,

x = y + 3 / 2

y = x - 3 / 2

Therefore f^-1(x) = x - 3 / 2

For c)

f ^ -1(12) = 12 - 3 / 2

= (24 - 3) / 2

= 21 / 2

Hope it will help :)

Answer:

35.228

Step-by-step explanation:

Answer:

b=21

Step-by-step explanation:

For this problem we need to use Pythagorean theorem (a^2+b^2=c^2):

20^2+b^2=29^2

Simplify the squares:

400+b^2=841

Subtract 400 from both sides:

b^2=441

Take the square root of both sides:

b=21

HTH :)

Answer:

Step-by-step explanation:

y=ax^2+bx+c we are given point (0,5) so if x=0, y=c, so c=5. We have two other points

(2,3)(4,9) which gives us

4a+2b+5=3 and 16a+4b+5=9

Subtracting twice the first from the second

16a+4b+5-8a-4b-10=9-6

8a-5=3

8a=8, so a=1, so using 4a+2b+5=3 we get

4(1)+2b+5=3

2b+9=3

2b=-6

b=-3 so our quadratic is

y=x^2-3x+5

Answer:

13x

Step-by-step explanation:

you would just add the 2 numbers together and then keep the variable. if you know the variable (if there’s a sheet to go off of) then multiply and add but otherwise it’s just 8 + 5 then add an x. 13x

=====================================================

Explanation:

x is a placeholder for a number. Think of it like a box holding a number. Conveniently, the letter 'x' is in the word 'box', so its naturally fitting to use x here.

Writing 8x could represent the idea of us having 8 boxes that are identical. Adding on 5x means we add on 5 more boxes. This leads to 8+5 = 13 boxes in total.

This is one way to see how 8x+5x = 13x

Another way is to write it like this: 8x+5x = (8+5)x = (13)x = 13x. I used the distributive property here.

Combining these terms is possible because 8x and 5x are like terms. They have the same variable and same exponent. We're adding two of the same type of object together.
