Answer:

(-2, -4)

Step-by-step explanation:

The solution to a system of equations is an ordered pair. In order to be a solution to a system of inequalities, it has to be in the shaded area of both lines. Since both lines are shaded below the lines, the point has to be in that middle area where both the green and purple shades overlap. (-2, -4) is the only point in that picture that is in that overlapping shaded area. (-4, -1) is only in the green shaded area.

Answer:

3.445.4.4..34.24'23.1.4

234.'2432342343224432

The function between the -4 and -1 is increasing and linear. Then the correct option is D.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

Describe the function between x = - 4 and x = -1.

As the value of x increases the value of the function also increases.

Then the function is an increasing function between -4 to -1.

Between -4 to -1 the function is a linear function.

Answer:

measure of angle E is 45 degrees because if you look closely then it is a

45, 45, 90 triangle, and so e is 45 degrees

Measure of c = 360-45+79+134 = 102 degrees

Step-by-step explanation:

The measures are 1) ∠ C = 101°, 2) ∠ Q = 89°, 3) ∠ M = 97°, 4) ∠ W = 34°, 5) x = 4 and 6) x = 13

A trapezoid, also known as a trapezium, is a flat-closed shape having 4 straight sides, with one pair of parallel sides. The parallel sides of a trapezium are known as the bases, and its non-parallel sides are called legs.

Given that, the quadrilateral in the figure is a trapezoid, we need to find the asked measures,

We know that, trapezoids are having one pair of opposite side parallel, therefore, adjacent angles are supplementary,

1) ∠ C + ∠ F = 180°

∠ C = 180°-79° = 101°

2) ∠ T + ∠ Q = 180°

∠ Q = 180°-91°

∠ Q = 89°

3) JKLM is an isosceles trapezoid, therefore, opposite angle are supplementary,

∠ M + ∠ K = 180°

∠ M = 180°-83°

∠ M = 97°

4) WXYZ is an isosceles trapezoid, therefore, opposite angle are supplementary,

∠ Y + ∠ W = 180°

∠ W = 180°-146°

∠ W = 34°

5) ∠ S + ∠ V = 180°

14x-15 + 139 = 180

14x = 180-124

x = 4

6) ∠ A + ∠ B = 180°

9x+2+5x-4 = 180

14x-2 = 180

14x = 182

x = 13

Hence, the measures are 1) ∠ C = 101°, 2) ∠ Q = 89°, 3) ∠ M = 97°, 4) ∠ W = 34°, 5) x = 4 and 6) x = 13

Answer:

how many times can Jenny predict she will roll a 12?

12 times

Step-by-step explanation:

180\12

The number of times 12 can come on the die is 15. The correct option is (C).

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lies in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

Given that,

Jenny rolls the 12 sided die 180 times.

Since a 12 sided die has number on each of its face ranging from 1 to 12.

The probability of getting 12 is given as,

P(getting 12) = Favorable number of outcome/Total possible outcomes

                    = 1/12

Now, the number of times 12 comes can be found as,

180 ×  1/12

= 15.

Hence, Jenny can predict that she will get 12 on the die for 15 times.

Answer:

1/2 cup of apple juice

Step-by-step explanation:

Hi,

1/4 cup of apple juice = 1/2 cup of carrot juice

We're trying to find the number of cups of apple juice when the carrot juice is equal to a whole cup. To do this, we have to get 1/2 to a whole number. Simply multiply 1/2 by 2 to get a whole number. Here's what I mean...

1/4 cup of apple juice = 1/2 cup of carrot juice

1/2 x 2 = 1 (whole number)

So, when we have a whole cup of carrot juice we have...

1/4 x 2 (since we multiplied the 1/2 by 2, we have to do the same to the other side).

1/4 x 2 = 1/2

David will use 1/2 cup of apple juice when he makes a cup of carrot juice.
