Pls help this is so confusing my brain is about to explode
zlopas [31]

Answer:

x=-20

Step-by-step explanation:

1. Expand 3(x+8) :  3x+24

2.Expand -3(7-1/4x):    -21*3/4x

3. 3x+24= -21*3/4x

4.<em>Subtract 24 from both sides</em>

3x+24-24= -21*3/4x-24

5.3x= 3/4x-45

6.<em>Subtract 3/4 from both sides</em>

3x-3/4= 3/4x-45-3/4

7.9/4x=-45

8<em>.Multiply both sides by 4</em>

9/4x*4=-45*4

9.9x=-180

10.<em>Divide both sides by 9</em>

9x/9=-180/9

11.   x=-20

A local veterinary clinic typically sees 15% of its horses presenting with West Nile virus. If 10 horses are admitted during Jul
NemiM [27]

Answer: D. 0.8202

Step-by-step explanation:

We would assume a binomial distribution for the number of horses presenting with West Nile virus. The formula is expressed as

P(x = r) = nCr × p^r × q^(n - r)

Where

x represent the number of successes.

p represents the probability of success.

q = (1 - p) represents the probability of failure.

n represents the number of trials or sample.

From the information given,

p = 15% = 15/100 = 0.15

q = 1 - p = 1 - 0.15

q = 0.85

n = 10

Therefore,

P(x ≤ 2) = P(x = 0) + P(x = 1) + P(x = 2)

P(x = 0) = 10C0 × 0.15^0 × 0.85^(10 - 0) = 0.1969

P(x = 1) = 10C1 × 0.15^1 × 0.85^(10 - 1) = 0.3474

P(x = 2) = 10C2 × 0.15^2 × 0.85^(10 - 2) = 0.2759

P(x ≤ 2) = 0.1969 + 0.3474 + 0.2759

= 0.8202

What is the axis of symmetry of the function f(x)=−(x+9)(x−21)?
Elena L [17]

Answer:

Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.

Step-by-step explanation:

i) f(x) = -(x+9)(x-21)

ii) therefore y = f(x) = -x^{2} + 12x + 189 =  - (x^{2} - 12x +36) + 36 + 189

iii) therefore y = f(x) = - (x-6)^{2}+ 225

iv) when x = 6 then y = 255

Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.
