Answer:

23(2+7y-())=0

Step-by-step explanation:

(10+13)(2+7y=)

We move all terms to the left:

(10+13)(2+7y-())=0

We add all the numbers together, and all the variables

23(2+7y-())=0

F(x) = 2(x - 3)^2 - 2

Natali5045456 [20]

Hi. I was unsure of what exactly you wanted from this equation, so here's a quick analysis:

f(x) = 2(x - 3)^2 - 2

Domain: (-∞, ∞)

Range: (-2, ∞)

X-intercepts: (4, 0), (2, 0)

Y-intercept: (0, 16)

Axis of Symmetry: x = 3

Minimum value (vertex): (3, -2)

Standard form: y = 2x^2 - 12x + 16

The Sugar Sweet Company is going to transport its sugar to market. It will cost $7500 to rent trucks, and it will cost an additi

Inga [223]

Let C represent the total cost (in dollars),
and let S represent the amount of sugar (in tons) transported

equation:
C(s) = 225s + 7500

find the total cost to transport 11 tons of sugar.
C(11) = 225(11) + 7500
C(11) = 2475 + 7500
C(11) = 9975

hope it helps

Order these ratios from least to greatest- 7:2, 12 to 4, 20/6, 21:14, 10:5 pls :,)

Brrunno [24]

Answer:

21:14, 10:5, 12 to 4, 20/6, and 7:2

Step-by-step explanation:

first simplify all the ratios.

the first one is already simplified

12 to 4 = 3 to 1

20/6 = 10/3

21:14 = 3:2

10:5 = 2:1

Next find the least common factor the the three digits, 1, 2, and 3 and which is 6.

Multiply the simplified factors into the least common factor. So 7:2 will be multiplied by 6 so it will be 21:6

Do it with the rest of the factors and get

21:6, 18 to 6, 20/6, 9:6, and 12:6

Finally order them from least to greatest,

9:6, 12:6, 18 to 6, 20/6, and 21:6

21:14, 10:5, 12 to 4, 20/6, and 7:2

Determine whether the given value is a solution of the equation. 36 = k 6 ; k = 6 6 a solution of 36 = k 6 .

Mila [183]

Answer:

Yes: the variable K would equal "6"

Step-by-step explanation:

After you set you equation up, you have to isolate the given variable. To do that you have to do the recipriocal (6k-multiplying) which would be division. You would divide k = 36 ÷ 6 . that isolates the variable ,which you would then solve. k = 6 .
