Step-by-step explanation:
A: √2 ≈ 1.4142135623730950488... an infinite non-repeating decimal (irrational)
B: √4 = 2 (rational)
C: ∛8 = 2 (rational)
D: √16 = 4 (rational)
Answer:
The equation of the line in the slope-intercept form is y = -5x + 79
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
- m is the slope of the line
- b is the y-intercept
∵ The slope of the line is -5
∴ m = -5
∵ The form of the equation is y = m x + b
→ Substitute the values of m in the form of the equation
∴ y = -5x + b
→ To find b substitute x and y in the equation by the coordinates
of any point on the line
∵ The line passes through the point (18, -11)
∴ x = 18 and y = -11
∵ -11 = -5(18) + b
∴ -11 = -90 + b
→ Add 90 to both sides to find b
∵ -11 + 90 = -90 + 90 + b
∴ 79 = b
→ Substitute it in the equation
∴ y = -5x + 79
∴ The equation of the line in the slope-intercept form is y = -5x + 79
Answer:c
Step-by-step explanation:
Hello!
To find the perimeter you do 2l + 2w.
l is length
w is width
put in the values we know
2(12) + 2w = 44
Combine like terms
24 + 2w = 44
Subtract 24 from both sides
2w = 20
Divide both sides by 2
w = 10
The answer is 10 meters
Hope this helps!
"x" is the "alternate interior" to the missing angle atop, and a flat-line, is just a line with an angle of 180°, thus, 28 + 103 + x = 180
