Let's substitute the value of x as 8 in the given equation to find the value of y ~

$\sf2x + y = 12$

$\sf(2 \times 8) + y = 12$

$\sf16 + y = 12$

$\sf y = 12 - 16$

$\sf y = - 4$

Which graph represents a reflection of f(x) = 2(0.4)x across the y-axis?

aleksley [76]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

In a reflection across the y-axis the y-coordinate remains the same, but the x-coordinate is transformed into its opposite

we have

$f(x)=2(0.4)^{x}$

The reflection of f(x) across the y-axis is equal to the function g(x)

$g(x)=2(0.4)^{-x}$

A certain lot consisting of ten items has three defective items and seven nondefective items. How many possible subsets of 2 ite

Charra [1.4K]

Answer:

Step-by-step explanation:

The order in which the items are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

How many possible subsets of 2 items can be chosen from this lot?

Combinations of 2 from a set of 10. So

$C_{10,2} = \frac{10!}{2!(10-2)!} = 45$

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (2, 5)

Point (-3, 7)

Step 2: Identify

x₁ = 2, y₁ = 5

x₂ = -3, y₂ = 7

Step 3: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{7-5}{-3-2}$
[Slope] [Fraction] Subtract: $\displaystyle m=\frac{2}{-5}$
[Slope] [Fraction] Rewrite: $\displaystyle m=\frac{-2}{5}$
