Answer:

The inequality that graphed is y ≥ 2x + 2 ⇒ B

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

  • m is the slope of the line
  • b is the y-intercept

In the given figure

∵ The equation of the line is y = m x  + b

∵ The line intersects the y-axis at the point (0, 2)

∴ b = 2

→ Use the rule of the slope m = \frac{y2-y1}{x2-x1} to find m

∵ The line passes through points (-1, 0) and (0, 2)

∴ x1 = -1 and y1 = 0

∴ x2 = 0 and y2 = 2

→ Substitute them in the rule above

∴ m = \frac{2-0}{0--1} = \frac{2}{0+1} = 2

→ Substitute the values of m and b in the equation above

∴ The equation of the line is y = 2x + 2

∵ The line is solid

∵ The shaded area is over the line

∴ The sign of inequality is ≥

∴ The inequality is y ≥ 2x + 2

∴ The inequality that graphed is y ≥ 2x + 2

Which sequence follows the rule an =an–1 + 7?
Akimi4 [234]

Answer:

A

Step-by-step explanation:

using the rule : a_{n} = a_{n-1} + 7

sequence A with a₁ = 11

a₂ = a₁ + 7 = 11 + 7 = 18

a₃ = a₂ + 7 = 18 + 7 = 25

a₄ = a₃ + 7 = 25 + 7 = 32

sequence A is generated using the rule

sequence B with a₁ = 17

a₂ = a₁ + 7 = 17 + 7 = 24

a₃ = a₂ + 7 = 24 + 7 = 31

a₄ = a₃ + 7 = 31 + 7 = 38

sequence B is not generated using the rule

sequence C with a₁ = - 15

a₂ = - 15 + 7 = - 8

a₃ = a₂ + 7 = - 8 + 7 = - 1

a₄ = a₃ + 7 = - 1 + 7 = 6

sequence C is not generated using the rule

sequence D with a₁ = - 9

a₂ = a₁ + 7 = - 9 + 7 = - 2

a₃ = a₂ + 7 = - 2 + 7 = 5

a₄ = a₃ + 7 = 5 + 7 = 12

sequence D is not generated using the rule
