Answer:

x = -2.25

Step-by-step explanation:

Add 15 to both sides of the equation

-6x - 15 = -1.5

-6x-15+15=-1.5+15

Simplify

-6x = 13.5

Divide both sides of the equation by the same term

-6x/6 = 13.5/6

Simplify

x = -2.25

At the dog park, 2 dogs are black with spots, 5 dogs are white with spots, 1 dog is solid white, and 4 dogs are solid black. Wha

Nikolay [14]

Its 11/12 , you need to divide the "wanted results" (every dog which is either black, with spots or both ) by every every possible result ( all dogs ). so 11/12=0.92

Shiyun bought a car in 1999. The value of the car V , in USD, is depreciating according to the exponential model

Anastaziya [24]

Hi there

a) the value of the car is 25000

b) v=25,000×1.5^(−0.2×3)=19,601

C) 12500=25000×1.5^(-0.2t)
Solve for t
12500/25000=1.5^(-0.2t)
Log (12500/25000)=-0.2t×log (1.5)
-0.2t=Log(12500/25000)÷log (1.5)
T=(log(12,500÷25,000)÷log(1.5))÷(−0.2)
T=8.55 years

Hope it helps

how do i write an equation of a quadratic formula when given the roots and y intercept? is there a formula i can plug the number

klio [65]

Answer:

y = -3x^2 +3x +6

Step-by-step explanation:

For roots p and q, the equation can be written as ...

y = a(x -p)(x -q)

The value of 'a' must be determined so that the product <em>apq</em> is equal to the y-intercept. One could say that the formula is ...

y = (y-intercept)/(pq)·(x -p)(x -q)

For your given values of p = 2, q = -1, y-intercept = 6, this becomes ...

y = 6/(2(-1))(x -2)(x +1)

y = -3(x^2 -x -2) . . . . . simplifying a bit

y = -3x^2 +3x +6
