An equation is y = -4x/3 + 10.

A graph of the equation is shown in the image attached below.

In order to write and graphically solve an equation that model this situation, we would assign variables to the number of pound of peaches and number of pounds of apples respectively, and then translate the word problem into algebraic equation as follows:

Next, we would translate the word problem into an algebraic equation as follows;

$2/pound × Pounds of peaches = 2x.

$1.50/pound × pounds of apples = 1.50y

Combining the two expressions above, we have the following:

2x + 1.50y = 15

Making y the subject of formula, we have:

1.50y = 15 - 2x

y = (15 - 2x)/1.50

y = -4x/3 + 10

Therefore, an equation in slope-intercept form that relates the variables is y = -4x/3 + 10.

Answer:

124 units squared

Step-by-step explanation:

A(parallelogram) = 8 x 10 = 80

A(semicircle) = πr²/2

however, we need to use the Pythagorean Theorem to find 'r'

r² + 6² = 8²

r² = 84-36

r² = 28

r = [tex]\sqrt{28}[/tex] = [tex]\sqrt{4}[/tex]·[tex]\sqrt{7}[/tex] or 2[tex]\sqrt{7}[/tex]

A = π(2√7)² / 2

A = 4·7π / 2

A = 14π which is approx 44

Total Area = 44 + 80 = 124

x = 4[tex]\sqrt{3}[/tex]

Step-by-step explanation:

cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex]  ( cross- multiply )

2x = 8[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

Answer:

They can make 2592 different burritos.

Step-by-step explanation:

In this question:

We multiply the number of options for each condiment.

1 choice of tortilla from a set of 3.

1 choice of meat from a set of 4.

1 choice of rice from a set of 2

1 choice of beans from a set of 3

1 choice of cheese from a set of 3

1 choice of salsa from a set of 4.

1 extra topping from a set of 3.

So

3*4*2*3*3*4*3 = 2592

They can make 2592 different burritos.

Answer:

0.871

Step-by-step explanation:

a. Solve the formula for r.

V = C (1 + r)²

dividing both sides by C, we have

V/C = (1 + r)²

(1 + r)² = V/C

taking square root of both sides, we have

√(1 + r)² = √(V/C)

1 + r = √(V/C)

r = √(V/C) - 1

b. Lew bought a condo 20 years ago for $50,000, and the current value of the condo is $175,000. Assuming the same

rate each year, what has the annual rate of appreciation been? Round your answer to the nearest half a percent.

Since r  = √(V/C) - 1 and V = $ 175,000 and C = $ 50,000

Substituting the values of the variables into the equation for r, we have

r  = √($ 175,000/$ 50,000) - 1

r  = √3.5 - 1

r = 1.871 - 1

r = 0.8708

r ≅ 0.871

Answer:

x-intercepts exist in the 3 functions

y-intercepts exist in the 3 functions

The function  h(x) has the lowest minimum.

The function  f(x) has the greatest maximum.

Step-by-step explanation:

Given

The attached table

Solving (a): x-intercepts

A function has x intercept if its y value equals 0.

From the table, we have:

[tex]f(2)=0[/tex]

[tex]g(4) = 0[/tex]

[tex]h(2) = 0[/tex]

All functions have x intercept

Solving (b): y-intercepts

A function has y intercept if its x value equals 0.

From the table, we have:

[tex]x = 0[/tex]

This applies to all functions in the table;

Hence, all functions have y intercept

Solving (c): Lowest minimum

The minimum of each function is:

[tex]f(x) = -12[/tex]

[tex]g(x) = -4[/tex]

[tex]h(x) = -60[/tex]

The lowest minimum is: h(x) because:

[tex]h(x) <f(x) < g(x)[/tex]

i.e.

[tex]-60 < -12 < -4[/tex]

Solving (d): Greatest maximum

The maximum of each function is:

[tex]f(x) = 12[/tex]

[tex]g(x) = 2[/tex]

[tex]h(x) = 0[/tex]

The greatest maximum is: f(x) because:

[tex]f(x) > g(x) > h(x)[/tex]

i.e.

[tex]12 > 2 > 0[/tex]

Answer:

1. f(x) g(x) h(x)

We need to set the two functions equal to each other and solve for d.

S^1(d) = S^2(d)

or,  0.45d³ - 3d² + 4.75d + 16  = 0.09d³ - 1.31d² + 7.25d + 18

Subtracting 0.09d³ - 1.31d² + 7.25d + 18 from both sides we get:

Answer:

B gets 5/13 of the candy bar.

Step-by-step explanation:

Given that a candy bar is being shared between two people, A and B, and A gets 3/5 times as much as B, to determine what fraction of the bar does B get the following calculation must be performed:

3/5 = 0.6

1.6 + 1 = 100

1 = X

2.6 = 100

1 = X

100 / 2.6 = X

38.46 = X

38.46% = 0.3846 = 5/13

Therefore, B gets 5/13 of the candy bar.

Answer lol faith

Step-by-step explanation:

1. The degree form of 4π/9 is approximately 228.6°.

2. A positive coterminal angle to -123° that is between 500° and 750° is 677°. A negative coterminal angle to -123° that is between -300° and -500° is -243°.

3. The terminal side of 215° lies in the second quadrant.

4. The radius of the circle is approximately 15.7.

1. The degree form of 4π/9 is approximately 228.6°. To express an angle in degrees, we multiply its radian measure by 180°/π.

2. A positive coterminal angle to -123° that is between 500° and 750° is 677°. A negative coterminal angle to -123° that is between -300° and -500° is -243°. To find a coterminal angle, we can add or subtract 360° as many times as necessary to bring the angle into the desired range.

3.

In the standard position, an angle is measured counterclockwise from the positive x-axis. The positive x-axis corresponds to the 0° angle, the positive y-axis corresponds to the 90° angle, the negative x-axis corresponds to the 180° angle, and the negative y-axis corresponds to the 270° angle. Angles in the first quadrant are between 0° and 90°, angles in the second quadrant are between 90° and 180°, angles in the third quadrant are between 180° and 270°, and angles in the fourth quadrant are between 270° and 360°.

So, the terminal side of 215° lies in the second quadrant.

4.

We can set up the equation l = Cθ/2π and solve for r.

Substituting the given values, we have 56π = (2πr)(120°/180°), which simplifies to r = 56π/(2π) = 28.

Dividing this value by 2, we get the radius of the circle as approximately 15.7.

Perimeter of a rectangle = 2 (length + width)

Perimeter = 96 cm

Width = 5 cm

Length = x

Now,

96 = 2 (x + 5)
