Graph f(x) = -2x - 1 with domain (-0,2]. State the range in the same notation.​

so it'd be the first, third and fourth one. all you gotta do is draw a vertical line through the middle of the 1st, 3rd and 4th.

Answer:

251$

Step-by-step explanation:

Let's say x represents Joes's account.

And y represents Chandra.

Since Joses account was 1 more than one half of chandra, the amount for Joes would be x = 1/2*y + 1

Now we can just say y = Chandra's amount.

So x + y = 751

And x = 1/2*y + 1

We have a systems of equation, and just plug in 1/2*y + 1 for x.

1/2*y + 1 + y = 751

1/2*y + y = 750 (subtract both sides by 1)

distribute y so...

y(1/2 + 1) = 750

y = 750/1.5

y = 500

Remember, y is Chandra. So plug in 500 for y in Joses equation, so 1/2(500) +

is 250 +1 so 251.

Step-by-step explanation:

Answer:Price of laptop A = $1220

Step-by-step explanation:

Sum of the price: A + B = 2185

Sum of the price: A + C = 2571

B : C = 5 : 7

B = 5/7 × C

So, replace the B:

A + 5/7 C = 2185

A + C = 2571

Eliminate by subtracting the first from the second: 2/7 C = 386

C = 1351

So, A = 2571 - 1351 = 1220

Answer:

15 boxes=3m=300cm

1 box=300cm÷15

=20cm

Answer:

Each box is 1/5 metres or 0.2 metres deep.

Step-by-step explanation:

There are 15 boxes, total height is 3 meters

Depth of each box:

[tex]15 \: boxes = 3 \: meters \\ 1 \: box = \{ \frac{(1 \times 3)}{15} \} \: meters \\ \\ = \frac{3}{15} \: m \\ \\ { \boxed{ \boxed{= \frac{1}{5} \: metres}}} \: \: or \: \: { \boxed{ \boxed{ = 0.2 \: m}}}[/tex]

Answer:

$2

Step-by-step explanation:

We're trying to find out 10% of the price of a bicycle

to do this, convert 20 to 0.20 and multiply it by 10%

0.20 × 10 = $2

it was sold for $2

Answer:

204 men.

Step-by-step explanation:

Total number of workers in all the companies = 42 * 12.

Total number of women in all the companies = 25 * 12.

So the total number of men = 12(42 - 25)

= 12 * 17

= 204 .

Answer:

204.

Answer:

p = - 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 7)

m = [tex]\frac{7-(-3)}{3-(-1)}[/tex] = [tex]\frac{7+3}{3+1}[/tex] = [tex]\frac{10}{4}[/tex] = [tex]\frac{5}{2}[/tex]

Parallel lines have equal slopes

Calculate the slope of the other 2 points and equate to [tex]\frac{5}{2}[/tex]

with (x₁, y₁ ) = (3, p) and (x₂, y₂ ) = (7, - 4p)

m = [tex]\frac{-4p-p}{7-3}[/tex] = [tex]\frac{-5p}{4}[/tex] = [tex]\frac{5}{2}[/tex] ( cross- multiply )

- 10p = 20 ( divide both sides by - 10 )

p = - 2

days = pages / rate

days = 81 // 3 pages / day

days = 27 days.

Answer:

1/12

Step-by-step explanation:

Imagine a whole cake which is split into thirds, then you cut each third into four equal pieces, at the total you'll have 12 pieces so you'll have 1/12.

1/3 * 1/4 = 1/12

If your talking about decimals 2.1 then:

Step 1) Convert 2.1 into a fraction; 21/10

Step 2) Convert 21/10 into a mixed number. 10 can go in 21 2 times, leaving us with 1. 2 is the whole number and 1 is the numerator. 10 will continue to be the deniometor.

2 1/10

Answer:

yea for sure

Step-by-step explanation:

So  the equation is y = x + 8. We already have the answers for x, so we just need to solve for y.

We can use this same equatoin to find y.

Let's start with the first example, 2.

y = 2 + 8. 2 + 8 = 10, so the first box would be 10.

next is 0. 0 + 8 is 8 , so the second box would be 8.

The third box has x as 4. 4+8 is 12, so the last box is 12.

Hope this helps!

x, y

(2, 10)

(0, 8)

(4, 12)

all you need to do is add the numbers under x 2,0,4 to 8. y=x+8 just plug the numbers in.

10=2+8

12=4+8

8=0+8

Answer:

48 inches

or

0.8 minutes

Step-by-step explanation:

To find the unit rate of inches per hour, divide 144 by 3.

144÷3=48

You don't need to round because there are no decimals.

To find the time to braid 1 inch, first multiply 3 by 60 (because there are 60 minutes in 1 hour).

3×60=180

Then divide 144 by 180.

144÷180= 0.8

You don't need to round because there are no thousandths.
