Step-by-step explanation:

b.3n/2 = 7/2

6n = 14

n = 2 1/3

c.-x/2 + 6 = -13/4

-x/2 = -37/4

-4x = -74

x = 18 1/2

d.3x/10 = 2/5

15x = 20

x = 1 1/3

e.x/10 = -20/3

3x = -200

x = -66 2/3

f.269x/56 = 10

269x = 560

x = 2 22/269

The function h is defined by h (y) = 2y-7. What is the value of h(8) ? ooo

kozerog [31]

Answer:

The value of h(8) = 9

Step-by-step explanation:

Given function as

h(y) = 2y - 7

For y = 8

Put the value of y in given function

So, h(8) = 2 (8) - 7

OR , h(8) = 16 - 7

∴ h(8) = 9

Hence the value of h(8) = 9 Answer

Algebra I

Coordinates (x, y)

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-5, 6) → x₁ = -5, y₁ = 6

Point (3, 2) → x₂ = 3, y₂ = 2

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formulas]: $\displaystyle d = \sqrt{(3+5)^2+(2-6)^2}$
[Distance] [√Radical] (Parenthesis) Add/Subtract: $\displaystyle d = \sqrt{(8)^2+(-4)^2}$
[Distance] [√Radical] Evaluate exponents: $\displaystyle d = \sqrt{64+16}$
[Distance] [√Radical] Add: $\displaystyle d = \sqrt{80}$
[Distance] [√Radical] Simplify: $\displaystyle d = 4\sqrt{5}$
