malfutka [58]

Answer:

$3+2(log_{2}(x+1) )$

Step-by-step explanation:

First simplify the quadratic present $8(x^{2}+2x+1)=8(x+1)^{2}$

$log_{2}8+log_{2}(x+1)^{2}$

⇒ $3+2(log_{2}(x+1) )$

Vladimir says that the equation of the line that passes through points (-5,-3) and (10,9) is y=4/5x+1 Robyn says that the line p

Talja [164]

Answer:

Robyn and Vladimir both are correct.

Step-by-step explanation:

Vladimir says that the equation of the line the passes through points (-5, -3) and (10,9) is y = $\frac{4}{5}$ x + 1

Let's find the equation of line

Slope of the line passing through ( -5, -3 ) and (10, 9 )

$m=\frac{y-y'}{x-x'}=\frac{9+3}{10+5}=\frac{12}{15}=\frac{4}{5}$

So equation will be y = $\frac{4}{5}$ x + c

Since the line passes through (-5, -3)

so (-3) = $\frac{4}{5}$ x (-5) + c

(-3) = -4 + c

c = -3 +4 = 1

So equation should be y = $\frac{4}{5}$ x +1

Therefore, Vladimir is correct.

Robyn says this line is passing through (-10,-7) and (-15, -11)

Slope $m=\frac{y-y'}{x-x'}=\frac{-11+7}{15+10}=\frac{-4}{-5}=\frac{4}{5}$

equation is y = $\frac{4}{5}$ x + c

Since this line passes through (-10 -7)

so (-7) = $\frac{4}{5}$ x (-10) + c

-7 = -8 + c ⇒ c = 8 - 7 = 1

Equation of the line will be y = $\frac{4}{5}$ x + 1

So Robyn and Vladimir both are correct.

If f(x) = 7(x - 1) + 8, find the value of f(1)<br> answer fast.

VladimirAG [237]

F(x) = 7(x-1)+8, so f(1) = 7(1-1)+8 [sub the x value in] = 7-7+8 = 8
