OK sooooo

distribute the -3 = -3x + 12

then subtract the 2 to the other side

then you get y = -3x + 10

Y + 2 = -3(x - 4)
y + 2 = -3x + 12
y = -3x + 12 - 2
y = -3x + 10 ...slope intercept form

3x + y = 10 <== standard form

The function f(x) = 3(1.9)x gives the length (in inches) of an image after being enlarged by 10% x times. What is the length of

Margaret [11]

Answer:

20.58 inches

Step-by-step explanation:

As the variable x represents the number of times the figure is enlarged, to find the length of the image after it has been enlarged 3 times, we just need to use the function f(x) with the value of x = 3:

f(x) = 3 * (1.9)^x

f(3) = 3 * (1.9)^3

f(3) = 3 * 6.859

f(3) = 20.577 inches

Rounding to nearest hundredth, we have f(3) = 20.58 inches

So the length of the image after being enlarged 3 times is 20.58 inches

What is this? Please answer if u know what u are doing oh and thank you for reading this

Vika [28.1K]

Answer: y= -1/3x+1
Explanation:
we can take any points from graph that intersect with the line and find the slope.
take (3,0) (0,1)
to find the slope subtract y-es and x-es
1-0/0-3
-1/3 is the slope
y=kx+b is the form of linear equation, where k is the slope,
hence,
y=-1/3x+b
put any points from the line to this equation.
for example - (3,0)
0=-1/3*3+b
1=b ( b is y intercept)
so our equation is
y=-1/3x+1
Hipe it helps! if you have questions, you can ask!:):)

Find the geometric mean between 12 and 20 find the answer in radical form

shusha [124]

Answer:

4√15

Step-by-step explanation:

The geometric mean of x and y is √(xy).

So here we have:

√(12*20)

= √240

= √(16*15)

= √16√15

= 4√15.

The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 13.1 years; the standard devia

Ilia_Sergeevich [38]

Answer:

The probability between 16.1 and 17.6 years = 0.0214 years

The Estimate probability between 16.1 and 17.6 years = 2.14 years

Step-by-step explanation:

Step(i):-

Given the average of Population 13.1 years

The standard deviation of the Population = 1.5 years

Let 'x' be the random variable in Normal distribution

Given x = 16.1

$Z _{1} = \frac{x- mean}{S.D}$

$=\frac{16.1-13.1}{1.5}$

= 2

Z₁ = 2

Step(ii):-

Given x = 17.6

$Z_{2} = \frac{17.6- 13.1}{1.5}$

Z ₂= 3

Z₁ = 2 and Z ₂= 3 are both positive

The Estimate probability between 16.1 and 17.6 years

P( 16.1<x<17.6) = P( 2 < Z < 3)

= A(3) - A(2)

= 0.49865 - 0.4772 (from normal table)

= 0.0214

The probability between 16.1 and 17.6 years = 0.0214 years

= 0.0214 ×100

= 2.14 years

Final answer:-

The Estimate probability between 16.1 and 17.6 years = 2.14 years
