Step-by-step explanation:

To draw the graph, follow these steps:

The three inequalities given form a triangle.

The first equation, y ≤ 2x + 5, has a y-intercept at (0, 5) and a point at (-2, 1).

The second equation, y < -3x + 10, has points at (3, 1) and (2, 4).

Use two points to draw the lines.

After the lines are drawn, determine which side of the line the inequality works on. You can do this by testing points that are not on the line.

I will test each inequality using (0, 1):

y ≤ 2x + 5

0 ≤ 2 + 5

This is correct, so the inequality for y ≤ 2x + 5 will be shaded towards (0, 1).

y < -3x + 10

0 < -3 + 10

This is correct, so the inequality for y < -3x + 10 will be shaded towards (0, 1).

0 ≤ 1

This is correct, so the inequality for 0 ≤ y will be shaded upwards towards (0, 1).

The end result of this graph is all three inequalities being shaded (inwards).

The solution is a triangle with points at (1, 7), (3.33333, 0), and (-2.5, 0).

the answer

Step-by-step explanation:

Answer:

possibility 1 - triplet:3, mother/father:35

possibilty 2 - triplet:1, mother/father:38

 Two possibilities for the family's ages are the (father 38, Mother 38, and triplets 1-year-old each) and the second possibility is (the father and mother 35 each and triplets 3 years old each).

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here, the father and the mother have identical age and also triplets.

let the age of mother and father be x and the triplets be y then we can form the equation is 2x+3y=79

Possibility 1)                          76   3 =79

Possibility 2)                       70    9 =79

In possibility one x=38 and y =1 and possibility 2 x=35 and y=3

Hence the two possibilities are  the (father 38, Mother 38, and triplets 1-year-old each) and the second possibility is (the father and mother 35 each and triplets 3 years old each).

Answer:

g(u) = -3/2 u + 1/4

Step-by-step explanation:

Solve for v

-12u +3 = 8v +1

Subtract 1 from each side

-12u +3-1 = 8v +1-1

-12u +2 = 8v

Divide each side by 8

-12u/8 +2/8 = 8v/8

-3/2 u + 1/4 = v

v = -3/2 u + 1/4

g(u) = -3/2 u + 1/4

Step-by-step explanation:

The graph which passes through the (0,0) point is the graph of f(x) = 3 sin (2x)

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The general form of a sine function is;

y = Asin(Bx+C) +D

where;

A is the amplitude.

B is the frequency.

From f(x) = 3 sin (2x), we can say that;

A = 3

This implies that the graph has waves that has height from -3 to 3.

B = 2

This means that there are two waves between 0 and 2π with the period of the function being π.

Hence, the graph goes through the (0,0) point.

Answer:

x = 9; Option C

Step-by-step explanation:

If p ║q, we are provided with the following properties;

Same Side Interior / Exterior ∠s ⇒ supplementary,

Alternate Interior / Exterior ∠s ⇒ ≅,

Corresponding ∠s ⇒ ≅

If we are focusing on the measure of two alternate interior angles, say a and b, we can assign them as such;

a ⇒ 9x + 8, and b ⇒ 15x - 46

m∠ a = m∠ b ⇒ provided they are alternate interior ∠s,

9x + 8 = 15x - 46 ⇒ Add 46 on either side of equation,

9x + 54 = 15x ⇒ Subtract 9x from either side,

54 = 6x ⇒ Divide either side by 6,

Solution; x = 9

Answer:

x = -3/5

Step-by-step explanation:

2(3 - x) -12 + 4x = -3x -9

Distribute

Combine like terms

2x -6 = -3x -9

Add 3x to each side

2x+3x -6 = -3x+3x -9

Add 6 to each side

5x -6+6 = -9+6

5x = -3

Divide each side by 5

Answer:

A

Step-by-step explanation:

Since all of the dimensions are being expanded by a scale of 1/4 of a foot to 3, or an increase of a factor of 12, the area is being increased by 12*12=144 times, or choice A. Hope this helps!

The unit rate of area in square feet of the enlargement image per square foot of the area of the original image is 144 square feet.

The scale of 1/4 of a foot = 3 feet

So scale of a foot = 3*4 =12 feet

A scale factor is a factor by which the dimension of an object is enlarged or diminished.

So, the area of the enlarged image = 12 feet*12 feet

The area of the enlarged image =144 square feet

Hence, the unit rate of area in square feet of the enlargement image per square foot of the area of the original image is 144 square feet.
