which of the following relations is a function ?

Answer:

I am pretty sure that it is the bottom left answer.

Step-by-step explanation:

Answer:

it would've been A the first one

Answer:

A. [–1, 1]

Step-by-step explanation:

The range is the values that the output can take

The values that sin can take go from -1 to 1 inclusive

Answer:

the first one is 8x-2a

second is 4x+6y

You should combine like factors- factors with the same variable and get your answer.

Answer:

3x-2a+5x+4a

8x + 2a

6x-2x+8y-2y

4x + 6y

explanation:

These are about combining "like terms" so you put the x-terms together by adding or subtracting the "coefficients," the numbers attached to the variables. Combine only terms that have the same letters when adding or subtracting.

Answer:

X=-6

Step-by-step explanation:

4(1−x)+3x=−2(x+1)

(4)(1)+(4)(−x)+3x=(−2)(x)+(−2)(1)(Distribute)

4+−4x+3x=−2x+−2

(−4x+3x)+(4)=−2x−2(Combine Like Terms)

−x+4=−2x−2

−x+4=−2x−2

Step 2: Add 2x to both sides.

−x+4+2x=−2x−2+2x

x+4=−2

Step 3: Subtract 4 from both sides.

x+4−4=−2−4

x=−6

Answer:

x=−6

Answer:

x=-2

Step-by-step explanation:

4 - 4x + 3x=-2x -2

4 -1x=-2x -2

4= -1x -2

2=-1x

x=-2

Answer:

Yes

Step-by-step explanation:

Only if its sold by a person and not a company, most people refer to that as an offer.

Answer:

Yup, it can

Step-by-step explanation:

In newspapers or online people do many offers/sales to get you to buy something. For example, let's say you see Gardening Services, that would be considered as an offer, because the salesperson or company is selling you something. Online, you could be sold offers as well, like a new phone, a house, etc.

Answer:

Step-by-step explanation:

length = 5 1/4 = 21/4 inches

Width = 2 1/2 = 5/2 inches

Height = 2 inches

Volume of rectangular prism = length * width * height

                     [tex]= \frac{21}{4}*\frac{5}{2}*2\\\\= \frac{21}{4}*5\\\\=\frac{105}{4}[/tex]

                     = 26.25 cubic inches

Answer:

26 1/4 i think

Step-by-step explanation:

5 1/4 times 2 1/2 times 2 is 26 2/8 but then you simplify it and you get 26 1/4

Answer:

AC=7.5 cm

CB=10.5cm

Step-by-step explanation:

Since we don't know the distance from C to B, we can label it as x. Our equation will be x+(x-3)=18. Simplify that so it is 2x-3=18. Add 3 to both sides and get 2x=21. x=10.5 So AC=7.5 cm and CB is 10.5 cm

Answer:

D

Answer:

its c i guess i thought it was B because it says the amount of water that remains in the water barrel remains means what is left and initially means at first so i guess its C

Step-by-step explanation:

please rate and give me a thanks if you wanna get more answers

Here, we are required to determine what the y-intercept represents.

The equation of a line is given by;

y = mx + c.

where m = slope

and c = y-intercept.

Since the y-axis represents the Gallons of water left in the tank.

The y-intercept represents the point which corresponds to when x = 0.

In this case, the y-intercept represents the amount of water that is initially in the water barrel. i.e 45gallons of water.

Answer:

Step-by-step explanation:

x + 85 = 180

x = 95

Answer:

Step-by-step explanation:

upper block:

length (l) = 120 cm

Width (w) = 30 cm

Height (h) = 60 cm

Volume of upper block = l * w * h

                                      = 120 * 30 *60

                                     = 216,000 cm³

Lower Block

l = 120 cm

w = 30 cm

h = 30 cm

Volume of lower block = 120 * 30 * 30

                                      = 108,000 cm³

Volume of steps = 216,000 + 108,000 = 324,000 cm³

Answer: 88 in2

Step-by-step explanation:

The side of the can, which when "unrolled" is a rectangle, with width = height of the cylinder (7 in); and length = Circumference = 2π radius

Surface area of the curved surface of the can = 2π (diameter/2) x height

Replacing with the values given:

S = 2π (4/2) x 7 = 2π (2) x 7 = 88 in2
