Find the common difference if the 8th term is 55 and the first term is 13

Vlad [161]

Answer:

Step-by-step explanation:

Equation

L = a + (n - 1)*d

Givens

L = 55

a = 13

n =8

Solution

55 = 13 + (8 - 1)*d Combine

55 = 13 + 7d Subtract 13 from both sides

55 - 13 = 7d

42 = 7d Divide by 7

d = 6

Answer:

For Question 1

$\angle Z =72$ °

For Question 2

$\angle Y =130$ °

Step-by-step explanation:

Given

$\angle X =108$ °

$\angle W =50$ °

For a Quadrilateral inscribed in a circle we have opposite angles are Supplementary that is

For question 1

$\angle X + \angle Z = 180\\108 + \angle Z =180\\\angle Z =180-108=72$

For question 2

$\angle W + \angle Y = 180\\50 + \angle Y =180\\\angle Y =180-50=130$

Algebra I

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Step-by-step explanation:

Step 1: Define

Point (-2, 6)

Point (8, 9)

Step 2: Find slope m

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

Substitute [SF]: $\displaystyle m=\frac{9-6}{8+2}$
Subtract/Add: $\displaystyle m=\frac{3}{10}$

Step 3: Write Function

Plug in variables into general form.

y - 9 = 3/10(x - 8)

y - 6 = 3/10(x + 2)
