Answer:

The value of y is 6.

Step-by-step explanation:

1) Since x = 1, you need to substitute x with 1.

2) Solve the equation

y = -4x + 10

y = -4(1) + 10

y = -4 + 10

y = 6

A 12-team soccer league has $7,260 to award as prize money. the team that finishes in last place will receive $220, and the priz

Anestetic [448]

Answer: $ 990

Step-by-step explanation:

Since, the total number players, n = 12,

The least amount got by one team, a= $ 220

Let there is a successive difference of d,

Thus, the given situation forms an AP,

In which sum of the AP, $S_n= \frac{12}{2}[2\times 220 + (12-1)d]$

But, According to the question,

$S_n = $ 7260$

⇒ $\frac{12}{2}[2\times 220 + (12-1)d]=7260$

$6[440 + (11)d]=7260$

$440 + 11 d=1210$

$11 d =770$

$d = 70$

Thus, the successive difference, d = $ 70

⇒ The amount of first price,

$a_{12} = 220 + (12-1)\times 70 = 220 + 770 = \$ 990$

Which can be used to describe the expression? Check all that apply.

Burka [1]

Answer:

B and D

Step-by-step explanation:

One thing is for certain. The final answer will be 1/r^12 or r^(-12)

When written as the given of (r^-4)^3, the powers are multiplied.

The first one is false. There are 4 factors of r^-4 If you get an answer that says it is true, then the question means that r^-4 is 3 equal factors of r^-12

B is true

C: not true. The exponents are multiplied, not added.

D is true

E: not true. This is the same thing as C.

What is the sine value of pi? A. -1/2 B. 1/2 C. 0 D. 1

slega [8]

Answer: C) 0

You can use a calculator to get this answer, a reference table, or the unit circle. The angle pi radians is equivalent to 180 degrees. Note how the point on the unit circle corresponding to 180 degrees is (1,0). This point has a y coordinate of zero. More broadly, y = sin(theta) where theta is the angle.
