Answer:
3(k - 1)² = 12
Step-by-step explanation:
To complete the square, write the equation standard form and make the a term's coefficient 1.
3k² = 11 + 6k
3k² - 6k - 11 = 0
3(k² - 2k) = 11
Take the middle term -2k and divide the coefficient in 2 and square it. Here it is -2/2 = -1. -1² = 1. Add 1 to both sides.
3(k² - 2k + 1) = 11 + 1
3(k - 1)² = 12
Answer:
183.5
Step-by-step explanation:
To round 183.47 to the nearest tenth consider the hundredths’ value of 183.47, which is 7 and equal or more than 5. Therefore, the tenths value of 183.47 increases by 1 to 5.
183.47 rounded to the nearest tenth = 183.5

Step-by-step explanation:
Slope intercept form of an equation is written as;
y=mx+b where m is the slope of the line and b is the y-intercept
Given points (3,19) and (8,42) find m as;
m=Δy/Δx
Δy=42-19=23
Δx=8-3=5
m=23/5
Finding the equation of the line where m=23/5, point (3,19) and (x,y)
m=Δy/Δx
23/5=y-19/x-3
cross product
23(x-3) = 5(y-19)
23x-69=5y-95
23x=5y-95+69
23x=5y-26
23x+26=5y
23x/5 +26/5 =5y/5
23/5 x +26/5 =y
⇒⇒ y=23/5x +26/5
