Answer:

Y= 42

Step-by-step explanation:

The answer would be 42 because if x=9 and the equation is 5x you have to multiply and that will give you 45 and then subtract 3 which would give you 42

What is the probability that a point chosen at random on the grid will lie in the shaded region?

Mashcka [7]

Given:

A grid with a shaded region.

To find:

The probability that a point chosen at random on the grid will lie in the shaded region.

Solution:

We have,

Total number of small boxes = 100

Number of blue boxes (shaded region) = 36

Now,

probability that a point chosen at random on the grid will lie in the shaded region is

$\text{Probability}=\dfrac{\text{Number of blue boxes (shaded region)}}{\text{Total number of small boxes}}$

$\text{Probability}=\dfrac{36}{100}$

To find the probability in percent, multiply it by 100.

$\text{Probability}\%=\dfrac{36}{100}\times 100$

$\text{Probability}\%=36\%$

Therefore, the correct option is A.

At which value in the domain does f(x)=0 ?

lina2011 [118]

f(x)=0

Domain are the set of x values

f(x)=0 , we find all the x values where y =0

At x intercepts y is always 0

so we find all the x intercepts.

x intercepts are the points where the graph crosses x axis

In the graph we can see that the graph crosses x axis at

-2.5 , -0.75 and 1

-2.5 , -0.75 and 1 are the domain where f(x)=0

Which is a rule that describes the translation of a point from 4, -8 to 7, -10

Alexxandr [17]

Answer:

$\large\boxed{(x,\ y)\to (x+3,\ y-2)}$

Step-by-step explanation:

$(4,\ -8)\to(7,\ -10)\\\\4\to7\Rightarrow4+3=7\\\\-8\to-10\Rightarrow-8-2=-10\\\\\text{Conclusion}\\\\(x,\ y)\to (x+3,\ y-2)$
