Answer:

y = $\frac{-4}{5}$ x + 1

Step-by-step explanation:

Slope is rise over run, or the vertical progression over the horizontal progression.

Your example has a line that heads downwards, so we know that the slope is negative. If we count the squares, the "rise" is down by 4. We count the squares going horizontally and there are 5. So, your slope is $\frac{-4}{5}$ .

The other half of the equation is the y-intercept, or where the line crosses the y axis. It appears to be at (0 , 1), so we can say that your y-intercept is 1.

(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

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

50 students were asked what they did last night. 16 said they read a book, 41 said they watched TV, 7 said they did neither, how

Kamila [148]

Answer:

14 students

Step-by-step explanation:

Given

Let:

$b \to$ read a book

$t \to$ watched TV

So, we have:

$n = 50$ -- total

$b = 16$

$t = 41$

$none = 7$

Required

Students that did both (x)

This is calculated using:

$Total = Books\ only + TV\ only + Both + None$

So, we have:

$n = (b - x) + (t - x) + x + none$

This gives:

$50 = (16 - x) + (41 - x) + x + 7$

Open brackets

$50 = 16 - x + 41 - x + x + 7$

$50 = 16 - x + 41 +7$

Collect like terms

$x = 16 - 50 + 41 +7$

$x = 14$

<em>Hence, 14 students did both</em>
