Answer:

I think quadrilateral and rhombus.

Step-by-step explanation:

Answer:

Slope: -1

Point-Slope Form: y - 2 = -1 (x - (-2))

Step-by-step explanation:

Answer: y-2=-1(x+2)

Step-by-step explanation: use whichever points you want I’m using (-2,2)

Find slope: y2-y1/x2-x1 so 2+2/-2-2 = 4/-4 = -1

Plug in these into y-y1= m(x-x1)

y-2= -1(x+2)

Answer:

i think 7 maybe?

Answer: 116

Answer:

$72 would be the retail price

Step-by-step explanation:

Answer:

Step-by-step explanation:

Since this is not factorable, let's just complete the square:

[tex]x^2+6x=19\\x^2+6x+9=28\\(x+3)^2=28\\x+3=\sqrt{28}\\x=2\sqrt{7}-3[/tex]

Answer:

x^5/x^2 = 2^5/2^2

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent. Subtract 2 from 5 to get 3.

23

Calculate 2 to the power of 3 and get 8.

8

hopefully i helped :)

Explanation:

I think that what you need to do is make the x 2? which makes it 2^5/2^2

2x2x2x2x2=32

2x2=4

so I think the answer is 32/4 which is 8

Answer:8

Answer: here is your answer

Step-by-step explanation:

You can put this solution on YOUR website!

+t+ = traveler's speed in ft/sec

+w+ = walkway's speed in ft/sec

given:

+t+-+w+=+2+

+t+%2B+w+=+6+

-------------

Add the equations

+2t+=+8+

+t+=+4+

and

+t+%2B+w+=+6+

+4+%2B+w+=+6+

+w+=+2+

The traveler's speed off the walkway is 4 ft/sec

The speed of the moving walkway is 2 ft/sec

Answer:

b

Step-by-step explanation:

Answer:

Speed of plane in still air: 490  mile/hour

speed of wind: 70  mile/hour

Step-by-step explanation:

still speed = x        wind speed = w

with wind: speed = still + wind

(x+w) * 3 = 1680     ...a

against wind: speed = still - wind

(x-w) * 4 = 1680    ...b

b-a ... 4x-4w-3x-3w = 0

x-7w = 0

x = 7w

substitution: (7w+w)*3 = 1680      8w = 560       wind speed (w) = 70

still speed (x) = 7w = 490 mile/hour

Answer:

80 pages

Step-by-step explanation:

Point slope Equation is :

y = mx + c

In the above question

y = 310 pages

x = number of days = 10 days

m= 23 pages per day

c = ?? Unknown

c = y - mx

c = 310 - 23 × 10

c = 310 - 230

c = 80 pages

She will still have 80 pages left to read after 10 days

Answer: 12:00 pm

Step-by-step explanation:

Valerie and her parents are goig to see her grandparents.

The grandparents leave 3 hours away.

They leave at 9:00 am.

The rime they'll arrive is therefore:

= 9 + 3 hours

= 12:00 pm

Answer:

x=12

Step-by-step explanation:

Subtract 2 from both sides

Subtract 2 from 12 to get 10

Divide both side by 5

Finally,divide 10 by 5 to get 2

5(2)+2=12

Answer:

20

Step-by-step explanation:

Any number with a decimal of .50 is rounded up. Anything less is rounded down.

So, 19.65 is rounded up to 20.

Answer:

0 = 0 miles

1 = 1.5 miles

2 = 3 miles

3 = 4.5 miles

4 = 6 miles

5 = 7.5 miles

Step-by-step explanation:

multiply each hour by 1.5

If a garden snail travels 1.5 miles per hour, then when 0 hours pass, it would have travelled 0 miles (no time has passed).

After 1 hour, it would have travelled 1.5 miles.

After 2 hours, it would have travelled 3 miles (1.5 miles × 2 hours).

After 3 hours, it would have travelled 4.5 miles (1.5 miles × 3 hours).

After 4 hours, it would have travelled 6 miles (1.5 miles × 4 hours).

After 5 hours, it would have travelled 7.5 miles (1.5 miles × 5 hours).

I hope this helps!

Answer:

[tex]x = 28[/tex]

Step-by-step explanation:

[tex]50 + (2x) + (3x - 10) = 180[/tex]

[tex]180-50=130[/tex]

[tex](2x) + (3x - 10) = 130[/tex]

[tex]5x - 10 = 130[/tex]

[tex]5x = 130 + 10[/tex]

[tex]5x = 140[/tex]

[tex] \frac{5x}{5} = \frac{140}{5} [/tex]

[tex]x= \frac{140}{5} [/tex]

[tex]x = 28[/tex]

Answer:

D.29

Step-by-step explanation:

all you have to do is replace the x's with -2
