Answer

Steps are included the distance formula is the square root of the equation (x2-x1)^2+(y2-y1)^2

$\sqrt{ \left( 2 - -4\right)^2 + \left( 3 - -5\right)^2}\\ \sqrt{ \left( 2 + + 0\right)^2 + \left( 3 + 5\right)^2}\\\sqrt{\left( 6\right)^2 + \left( 8\right)^2}\\\sqrt{ 36 + 64 }\\ \sqrt{ 100 } \approx 10$

your final answer is 10

Answer:

Step-by-step explanation:

Given equation is,

a). y = $\frac{6}{x}$

x 0.5 1 2 3 4 5 6

y $\frac{6}{0.5}=12$ $\frac{6}{1}=6$ $\frac{6}{2}=3$ $\frac{6}{3}=2$ $\frac{6}{4}=1.5$ $\frac{6}{5}=1.2$ $\frac{6}{6}=1$

b). By plotting the input-output values on the graph we get the curve as shown in option C.

Therefore, Option C will be the answer.

5. During the election for class president,

Alex Ar [27]

60 more students voted for Kevin

Step-by-step explanation:

Given

total students = 300

Voted for Jennifer = 40%

Voted for Kevin = 60%

We will find number of students for one of them and then will subtract from total to find the others.

So,

Students who voted for Jennifer:

$= 40\%\ of\ 300\\=0.40*300\\=120\ students$

Students who voted for Kevin

= $=Total\ students-Students\ who\ voted\ for\ Jennifer\\=300-120\\=180\ students$

In order to calculate that how many more students voted for Kevin :

180-120 = 60

Hence,

60 more students voted for Kevin

Solve the logarithmic equation. When necessary, round answer to the nearest hundredth. log 3(x + 4) - log 3(x + 2) = log 327

alexandr1967 [171]

Answer:

$x = -\dfrac{25}{13}$

Step-by-step explanation:

$\log_3{x + 4} - \log_3{x + 2} = \log_3 {27}$

$\log_3 \dfrac{x + 4}{x + 2} = \log_3 {27}$

$\dfrac{x + 4}{x + 2} = 27$

$x + 4 = 27(x + 2)$

$x + 4 = 27x + 54$

$-26x = 50$

$x = -\dfrac{50}{26}$

$x = -\dfrac{25}{13}$

How can you tell if an equation has direct variation? (Direct variation means proportional)

mario62 [17]

Direct variation/proportional means that one variable is always a multiple of the other variable.

It looks something like $y = n /cdot x$ , where n is any number.

The students in Gwen's class got to choose between pizza and burgers for the celebration on

Oksana_A [137]

Answer:

80% of the class picked the pizza

Step-by-step explanation:

In order to find a percentage, you are supposed to divide the amount of how much someone has picked by the total amount (in this case pizza's). Here is how I got 80%,

28/35 = 0.8

0.8*100 = 80

So the answer is 80%
