What is X Plus -8 equals 3x plus 6

Answers

Answer 1

Answer: x + -8 = 3x + 6
x - 8 = 3x + 6
(x - 8) + 8 = 3x + 6 + 8
x = 3x + 14
x - 3x = (3x + 14) - 3x
-2x = 14
2x = -14
x = -7

Answer 2

Answer: x=7 this is how you do it you just combine like terms but there isn't so you just add 8 to both sides so it would be x=3x+14 then you would subtract 3x to both side and it would be -2x=14 then divide by 2 not negative two and get x=7 because you can't have something equal negative x

Answer:

see explanation

Step-by-step explanation:

The y- intercept is at (0, 6) ⇒ c = 6

The x- coordinate of the vertex is at the midpoint of the zeros, that is

m = $(-3-1)/(2)$ = $(-4)/(2)$ = - 2

Since the zeros are x = - 3 and x = - 1 then the factors are (x + 3), (x + 1) and

f(x) = a(x + 3)(x + 1) = a(x² + 4x + 3)

Comparing with f(x) = ax² + 8x + 6 ⇒ a = 2

Thus

f(x) = 2x² + 8x + 6

Substitute m = - 2 into the equation for value of n

n = 2(- 2)² + 8(- 2) + 6 = 8 - 16 + 6 = - 2

Hence

c = 6, m = - 2, a = 2, n = - 2

Answer:

c = 6, m = - 2, a = 2, n = - 2

a doctor order calls for you to administer 0.1 mg of epinephrine in stock is a 1ml ampule that contains1 mg of epinephrine caculate the volume needed for this injection

Answers

If 1 ml of volume contains 1 mg of epinephrine, then 0.1 ml of volume contains 0.1 mg of epinephrine.

Let x be the number of ml you need.

Ratio: 1 ml is to 1 mg as x ml is to 0.1 mg

(1 ml)/(1 mg) = (x ml)/(0.1 mg)

Cross multiply.

1 * x = 1 * 0.1

x = 0.1

Answer: 0.1 ml
