Answer:

$A.\:-4\le y\le 8$ .

Step-by-step explanation:

The range of the range of the function refers to the y-values for which x is defined.

Observe that there are 5 boxes from 0 to 10 on the y-axis.

This means that each box is 2 units.

From the graph the least y-value is $-4$ and the highest y-value is 8.

The range is $-4\le y\le 8$ .

Answer:

Correct choice is A

Step-by-step explanation:

The range of the function are all possible values which variable y can take.

From the given diagram you can see that the variable x changes from -4 to the 9. So the domain of the function is $-4\le x\le 9.$

Also the variable y takes its values from -4 to 8. Thus, the range is $-4\le y\le 8.$

What is the solution of the systems of equations y=-3x-3 and y=-0.5x+2?

Leto [7]

This is two lines in slope intercept form and we want their intersection. We just set the ys equal.

-3x - 3 = (-1/2)x + 2

Multiply both sides by 2 to clear the fractions,

-6x - 6 = -x + 4

-10 = 5x

x = -10/5 = -2

y = -3x - 3 = -3 (-2) - 3 = 6 - 3 = 3

Check:

y = (-1/2)x + 2 = (-1/2)(-2) + 2 = 1 + 2 = 3, good

Answer: x=-2, y=3

Sylvia is hiking from Mineral Creek to Blueberry Hilla distance points of 6 1/5 miles. After hiking 2 2/3 miles , Sylvia stops f

Margarita [4]

Given:

Total distance = $6\dfrac{1}{5}$ miles

Hiking before lunch = $2\dfrac{2}{3}$ miles

To find:

How much further does Sylvia have left to hike?

Solution:

Let x be the remaining hiking distance.

We know that,

Total hiking distance = Hiking before lunch + Remaining hiking distance

$6\dfrac{1}{5}=2\dfrac{2}{3}+x$

$\dfrac{(6\times 5)+1}{5}=\dfrac{(2\times 3)+2}{3}+x$

$\dfrac{30+1}{5}=\dfrac{6+2}{3}+x$

$\dfrac{31}{5}=\dfrac{8}{3}+x$

Isolate variable term.

$\dfrac{31}{5}-\dfrac{8}{3}=x$

$\dfrac{93-40}{15}=x$

$\dfrac{53}{15}=x$

It can be written as

$\dfrac{45+8}{15}=x$

$\dfrac{(3\times 15)+8}{15}=x$

$3\dfrac{8}{15}=x$

So, $3\dfrac{8}{15}$ miles left to hike.

Therefore, the correct option is C.

A linear function is a function that creates a straight line when graphed. The difference between this graph and others is that this function is constant instead of curved. I’d like to see an example of this in the real world as a relationship between profit and merchandise.A quadratic function is a function that has multiple variables allowing the graph to curve. The difference between this function and the others is that this function is squared allowing for a greater curve that looks like a U. I’d like to see a example of this in the real world as missiles being launched since the curve is similar.A exponential function is a function in which the function grows at a fast rate. The difference between this function and the others is that this function curves in a constant rate then the x increases continuously. I’d like to see an example of this in the real world as the interest in a bank since it increases per month.

The probability of Elizabeth winning the soccer game is 0.72. What is the probability of not winning the game?

Rom4ik [11]

Answer:

.28 = P( not winning)

Step-by-step explanation:

The probability of winning is .72

The 2 possibilitites are winning and not winning. They must total 1

1 = P(winning) +P( not winning)

1 = .72 + P( not winning)

Subtract .72 from each side

1-.72 = P( not winning)

.28 = P( not winning)
