Answer:

y=1x-1

Step-by-step explanation:

y=mx+b is the equation to find the y intercept, here our line is linear and intercepts on point -1 on a graph, so now we know what our b is. Next, you want to see what the slope (mx) is. x is automatically assumed to be one, so you move your point one to the right (because it is positive) then you figure out how far up until it touches another point, in this case going from (-1,0) moving up one and right one brings you to (0,1) and you continue moving up or down that slope to your points.

6-√8 divide √2-1

agasfer [191]

Answer:

4 $\sqrt{2}$ +2

Step-by-step explanation:

$\frac{6-\sqrt{8}}{\sqrt{2}-1}$

= $\frac{6-\sqrt{8}}{\sqrt{2}-1}$ × $\frac{\sqrt{2}+1}{\sqrt{2}+1}$

= $\frac{(6-\sqrt{8})(\sqrt{2}+1)}{2-1}$

=6 $\sqrt{2}$ + 6 - $\sqrt{8}\sqrt{2}$ - $\sqrt{8}$

=6 $\sqrt{2}$ + 6 - 4 - $\sqrt{8}$

=6 $\sqrt{2}$ + 2 - $\sqrt{8}$

=6 $\sqrt{2}$ + 2 - 2

=4 $\sqrt{2}$ +2

for $\sqrt{8}$ = 2 $\sqrt{2}$ ,

$\sqrt{8}$ = $\sqrt{2*2*2}$

= ( $\sqrt{2}$ )^2 × $\sqrt{2}$

=2 × $\sqrt{2}$

sveticcg [70]

Answer:

$\frac{x}{y}=1.3$

Step-by-step explanation:

<u>Informação recuperada:</u>

(UFRGS) Se 10x = 20y , atribuindo 0,3 para log 2 , então o valor de x/y é

1) Primeiro, passando o 10 para o 2º membro como base do logaritmo:

$10x=20y \Rightarrow x=log_{10}20y$

2) Aplicando a propriedade do produto de logaritmo:

$log(AB)= logA+logB$

$x=log_{10}20y \Rightarrow x=log(2+10)y\Rightarrow x=(0.3+1)y \Rightarrow x=1.3y$

3) Como quero o quociente divido ambos os lados por y

$\frac{x}{y}=\frac{1.3y}{y}\Rightarrow \frac{x}{y}=1.3$

Find the y intercept

erica [24]

Step-by-step explanation:

Slope of line ST = Slope of line PQ = -3.

y = -3x + c

When x = 3, y = -1

=> (-1) = -3(3) + c, c = 8

Therefore the equation of line ST is y = -3x + 8 and the y-intercept is 8.

Which of the following describes the following graph?

pychu [463]

<u>Answer:</u>

The correct answer option is B. both a function and a relation.

<u>Step-by-step explanation:</u>

We are given a from from which we can see that for each input we have exactly one output.

This means that we have a function because each element in the domain is matched with exactly one element in the range.

It is also a relation since each input related to the out put in some way.

Therefore, the correct answer option is B. both a function and a relation,
