Answer 1

Answer:

9x² + 16y² - 24xy

Step-by-step explanation:

(3x - 4y)²

⇒ (3x)² + (4y)² - 2 (3x) (4y)                                            {(a - b)² = a² + b² - 2ab}

⇒ 3²x² + 4²y² - 2 (12xy)

⇒ 9x² + 16y² - 24xy

Alana has 2 1/4 bags of chocolate chips that she wants to use in 3 batches of chocolate chip cookies. How much of the chocolate chips will she use in each batch of cookies?

Answers

Answer:

1 1/3 bags of chocolate chips

Step-by-step explanation:

If Alana has 2 1/4 bags of chocolate chips that she wants to use in 3 batches of chocolate chip cookies, then we can say;

2 1/4 bags of cookies = 3 batches of chips

To determine how much of the chocolate chips will she use in each batch of cookies, we can say;

1 bag of cookies = x batches of chips

Equating both expressions

2 1/4 bags of cookies = 3 batches of chips

1 bag of cookies = x batches of chips

Cross multiply

2 1/4 x = 3

9/4 x = 3

9x/4 = 3

9x = 12

x = 12/9

x = 4/3

x = 1 1/3

Hence Alana will need 1 1/3 bags of chocolate chips

Ariana has a dimes and y nickels. She has at most 12 coins worth a minimum of
$0.85 combined. Solve this system of inequalities graphically and determine one
possible solution.
PLEASE HELP

Answers

Answer:

Solution graph is attached in the answer area.

And one possible solution is (9, 2).

9 number of dimes and 2 number of nickels.

Step-by-step explanation:

Given that:

Number of dimes = [tex]a[/tex]

Number of nickels = [tex]y[/tex]

Total number of coins are at most 12 OR total number of coins are lesser than or equal to 12.

i.e. the inequality can be written as:

[tex]a+y \leq 12[/tex] ...... (1)

One dime is worth 10 cents or $0.10.

[tex]a[/tex] number of dimes are worth $0.10[tex]a[/tex].

One nickel is worth 5 cents or $0.05.

[tex]y[/tex] number of nickels are worth $0.05[tex]y[/tex].

Second inequality can be written as:

[tex]0.10a + 0.05 \ge 0.85[/tex]

OR

[tex]2a+y\ge17[/tex] ...... (2)

[tex]a \ge 0, y \ge 0[/tex] ...... (3)

When we graphically represent the inequalities, the graph attached in the answer area represents the answer.

One solution is (9, 2).

9 number of dimes and 2 number of nickels.

Answer:

∠GEF = 25

Step-by-step explanation:

Here, we want to find the value of the marked angle

Please check the attachment for the diagrammatic representation of the triangle

Mathematically, the sum of opposite interior angles equals the exterior angle

We can have this sum as follows;

∠EFG + ∠GEF = ∠FGH

Thus;

2x + 1 + x + 19 = 6x + 2

3x + 20 = 6x + 2

6x-3x = 20-2

3x = 18

x = 18/3

x = 6

Now , substitute x into the ∠GEF

That will be;

6 + 19 = 25

Evaluate the expression 2n - 6 if n = 16.

Answers

Answer:

[tex]26[/tex]

Step-by-step explanation:

[tex]2n-6[/tex]

Given that:

[tex]n=16[/tex]

To evaluate the expression, we must simply substitute the given value of [tex]n[/tex], which is [tex]16[/tex], for [tex]n[/tex]:

[tex]2(16)-6[/tex]

Multiply:

[tex]32-6[/tex]

Subtract:

[tex]26[/tex]

-

To check your work, simply set the given expression equal to our solution, [tex]26[/tex]:

[tex]2n-6=26[/tex]

Add [tex]6[/tex] to both sides of the equation:

[tex]2n=32[/tex]

Divide both sides of the equation by the coefficient of [tex]n[/tex], which is [tex]2[/tex]:

[tex]n=16[/tex]

Since it matches the given value of [tex]n[/tex], our solution is correct!

Answer:

26

Step-by-step explanation:

This is the answer because:

1) First, we have to substitue the value that stand for n into the equation:

2(16) - 6

2) Next, we have to follow the order of operations in order to find the answer:

1. 2 x 16 = 32

2. 32 - 6 = 26

Therefore, the answer is 26.

f(x) = [tex]\frac{-h(x) + 7}{4}[/tex]

Step-by-step explanation:

h(x) is defined by the formula,

h(x) = -4f(x) + 7

If the graph attached is of the function 'h' and we have to find the function 'f',

h(x) - 7 = -4f(x)

Joshua is making spaghetti and meatballs for dinner for his friends. Joshua makes 30 meatballs. If Joshua wants 5 meatballs on each plate of spaghetti, how many plates can Joshua make? Write an equation to represent the scenario, and solve.

Answers

Answer:

[tex]x = 6[/tex]

Step-by-step explanation:

Given

Let y represent the number of meatballs in total and x represents the number of plates.

[tex]y = 30[/tex]

[tex]Rate = 5[/tex] per plate

Required

Determine the value of x

To solve for x, we make use of the following expression.

[tex]y = Rate * x[/tex]

Substitute values for y and Rate

[tex]30 = 5 * x[/tex]

[tex]30 = 5 x[/tex]

Divide through by 5

[tex]30/5 = 5 x/5[/tex]

[tex]6 = x[/tex]

[tex]x = 6[/tex]

Hence, number of plates is 6

Find the value of a3 + 3b2 when a = 2 and b = -2

Answers

Given:

a = 2 and b = -2.

To find:

The value of [tex]a^3+3b^2[/tex].

Solution:

We need to find the value of expression [tex]a^3+3b^2[/tex] at a = 2 and b = -2.

Substituting a = 2 and b=-2 in [tex]a^3+3b^2[/tex], we get

[tex](2)^3+3(-2)^2[/tex]

[tex]=8+3(4)[/tex]

[tex]=8+12[/tex]

[tex]=20[/tex]

Therefore, the value of expression [tex]a^3+3b^2[/tex] at a = 2 and b = -2 is 20.

Write an equation of the line in slope-intercept form.

f(3)=-2, f(0)=1

Answers

Answer:

The equation of the line in slope-intercept form is y = -x + 1

Step-by-step explanation:

The slope-intercept form of the linear equation is y = m x + b, where

m is the slope of the lineb is the y-intercept ⇒ value y at x = 0

The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where

(x1, y1) and (x2, y2) are two points on the line

∵ f(x) = y ⇒ is the function of the set of ordered pairs (x, y)

f(3) = -2 is the point (3, -2)

f(0) = 1 is the point (0, 1)

∴ x1 = 3 and y1 = -2

∴ x2 = 0 and y2 = 1

→ Substitute them in the rule of the slope to find it

∵ m = [tex]\frac{1--2}{0-3}[/tex] = [tex]\frac{1+2}{-3}[/tex] = [tex]\frac{3}{-3}[/tex]

m = -1

→ Substitute it in the form of the equation above

∵ y = -1(x) + b

∴ y = -x + b

∵ b is the value of y at x = 0

∵ at x = 0, y = 1

b = 1

∴ y = -x + 1

The equation of the line in slope-intercept form is y = -x + 1
