A single chicken lunch will cost $7 so option (C) will be correct.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say the cost of chicken = c

cost of ham = h

Given,

Sharon's Deli charged the Business Club $231 for 18 chicken lunches and 14 ham lunches.

So,

18c + 14h = 231

And,

$225.00 for 15 chicken lunches and 16 ham

So,

15c + 16h = 225

By solving both equations

h = 7.5 and c = 7

Hence, a single chicken lunch will cost $7

The rule for translating a point 'k' units to the right is

[tex](x,y)\to (x+k,y)[/tex]

If the point located at (-5, 2) is translated right 3 units, the coordinates of the image is obtained by adding 3 to the x-coordinate.

This implies that,

[tex]( - 5,2)\to ( - 5+3,2)[/tex]

[tex]( - 5,2)\to ( -2,2)[/tex]

Therefore the image is:

(-2,2)

Answer:

(-2, 2)

Step-by-step explanation:

We are given the following coordinates of a point:

[tex](-5, 2)[/tex]

If this point is translated to the right for 3 units, what will be the coordinates of its image?

Translation towards right side for 3 units means that 3 units are added to its x coordinate so the new point will be:

[tex] ( - 5 , 2 ) [/tex] [tex] \implies [/tex] [tex] ( - 5 + 3 , 2 ) = [/tex] (-2, 2)

Hello! Based on this problem, 68 is part of a whole. To solve it, we can write and solve a proportion. Set it up like this:

68/x = 85/100

Cross multiply the sections. 68 * 100 is 6,800 and 85 * x is 85x. So you get 6,800 = 85x. Now, divide each side by 85 to isolate the x. 85x/85 cancels out. 6,800/85 is 80. We can check this answer by multiplying 80 by 85%. 80 * 85% (0.85) is 68. There's our answer. 68 is 85% of 80.

The number whose 85 percent gives 68 is 8000.

Given the parameters in the question:

Given Value = 68

Percentage = 85%

To find the number whose 85 percent gives 68, we can use the following formula:

Number = (Given Value / Percentage) × 100

First, convert 85% from percent to decimal:

85% = 85/100 = 0.85

Now, plug these values into the above formula:

Number = (Given Value / Percentage) × 100

Number = ( 68 / 0.85 ) × 100

Number = 80 × 100

Number = 8,000

Therefore, 68 is 85% of the number 8000.

Answer:

a.  (15, 15)

Step-by-step explanation:

We start with those two equations:

1) a - 1.2b = -3

2) 0.2b + 0.6a = 12

We'll begin by modifying equation #1 to isolate a:

a = -3 + 1.2b

Then we'll use this value for a in the second equation:

0.2b + 0.6 (-3 + 1.2b) = 12

0.2b - 1.8 + 0.72b = 12

0.92b = 13.8

b = 15

Then we'll place that value of b in the first equation to find a:

a - 1.2 (15) = -3

a - 18 = -3

a = 15

Answer:

(15,15) is right

Therefore, the constant term is 2.

Answer:

Step-by-step explanation:

Given that you invest $150 at 7% interest compounded annually. Now we need to find about in how many years will you have $400. Then round the  answer ot the nearest tenth of a year.

So plug the given values into compound interest formula.

[tex]A=P\left(1+r\right)^t[/tex]

[tex]400=150\left(1+0.07\right)^t[/tex]

[tex]\frac{400}{150}=\left(1+0.07\right)^t[/tex]

[tex]\ln\left(\frac{400}{150}\right)=\ln\left(1+0.07\right)^t[/tex]

[tex]\ln\left(\frac{400}{150}\right)=\ln\left(1.07\right)^t[/tex]

[tex]\ln\left(\frac{400}{150}\right)=t\cdot\ln\left(1.07\right)[/tex]

[tex]\frac{\ln\left(\frac{400}{150}\right)}{\ln\left(1.07\right)}=t[/tex]

[tex]14.4967313882=t[/tex]

Answer:

B.  8 in^2.

Step-by-step explanation:

Let the width be x inches, then the length = x + 2 inches.

So by The Pythagoras theorem:

(√20)^2 =  x^2 + (x + 2)^2

x^2 + x^2 + 4x + 4 = 20

2x^2 + 4x - 16 = 0

x^2 + 2x - 8 = 0

(x + 4)(x - 2) = 0

x = 2, -4    (we ignore the negative so x = 2)

So the area = 2 * (2 + 2)

= 8 in^2.

Answer:

B

Step-by-step explanation:

L = W + 2

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

(W + 2)2 + W2 = [tex]\sqrt{20} ^{2[/tex]  

2[tex]w^{2}[/tex] + 4W + 4 = 20

2[tex]w^{2}[/tex] + 4W − 16 = 0

W = 2 or W = −4

And,

L = W + 2

L = 2 + 2

L = 4

Therefore,

A = LW = (4)(2) = 8

Step by step explanation:

You first subtract z on both sides of the equal sign

ax-bx=(z-y)

Since a and b both have a "x" you can subtract them

(a-b)x=(z-y)

then you divide "x" on both sides of the equal sign

[tex]\frac{a - b}{x} = \: \frac{z - y}{x} [/tex]

To find x in the equation ax-bx+y=z, combine like terms, subtract y from both sides, and then divide by (a-b) to get the formula x = (z-y)/(a-b).

To find the value of x in the equation ax - bx + y = z, you can follow these steps:

This step-by-step process allows you to solve for x in terms of a, b, y, and z.

Answer:

The answer is x=9 and/or x = -12

Step-by-step explanation:

This is a quadratic formula meaning that you must take the a value (1) b value (3) and the c value (108) and plug it into the quadratic formula.

[tex]\frac{-3±\sqrt{9+4*1*-108} }{2}[/tex]

which simplifies to -3 add or subtract the sqrt of 441 divided by two.

To solve the equation x² + 3x - 108 = 0, we use the quadratic formula, which gives two solutions: x = 9 and x = -12.

The question asks to solve the quadratic equation x2 + 3x - 108 = 0. To solve this equation, we will use the quadratic formula, which is given by x = (-b ± √(b2 - 4ac)) / (2a), where a, b, and c are the coefficients from the quadratic equation ax2 + bx + c = 0. In our case, a = 1, b = 3, and c = -108.

Substituting these values into the quadratic formula gives us:

x = (-(3) ± √((3)2 - 4 ×(1) ×(-108))) / (2 ×(1))

x = (-3 ± √(9 + 432)) / 2

x = (-3 ± √441) / 2

x = (-3 ± 21) / 2

This results in two possible values for x:

So, the solutions to the equation x2 + 3x - 108 = 0 are x = 9 and x = -12.

Divide the 2nd term by the first to find the ratio which is also n.

Answer:

n=5.

Step-by-step explanation:

The given geometric series is

1+ 4 +16 + 64 + 256

In the given G.P.  the number of terms is 5 and n represents the number of terms in a G.P. So, n=5.

Alternate method:

Here the first term is 1 and the common ratio is

[tex]r=\dfrac{a_2}{a_1}=\dfrac{4}{1}=4[/tex]

The nth term of a G.P. is

[tex]a_n=ar^{n-1}[/tex]

where, a is first term and r is common ratio.

Substitute a=1, an=256 and r=4 in the above formula.

[tex]256=(1)(4)^{n-1}[/tex]

[tex]4^4=4^{n-1}[/tex]

On comparing both sides we get

[tex]4=n-1[/tex]

Add 1 on both sides.

[tex]5=n[/tex]

Therefore, the value of n is 5.

To find the polynomial of degree 3 with real coefficients and specific zeros and y-intercept, we use the fact that complex zeros occur in conjugate pairs. We can express the polynomial as f(x) = a(x-3)(x-(1+3i))(x-(1-3i)), where a is a constant. By plugging in the y-intercept value, we can solve for the constant a.

To find the polynomial with degree 3 and real coefficients that has a y-intercept of 60 and zeros 3 and 1+3i, we can use the fact that complex zeros occur in conjugate pairs. Given that 1+3i is a zero, its conjugate 1-3i is also a zero. Therefore, the polynomial can be expressed as f(x) = a(x-3)(x-(1+3i))(x-(1-3i)), where a is a constant.

Since the polynomial has a y-intercept of 60, we know that f(0) = 60. Plugging in x=0, we can solve for the constant a:

f(0) = a(0-3)(0-(1+3i))(0-(1-3i)) = 60

Since the constant a is the only unknown variable, we can solve for it:

-3*(1+3i)*(1-3i) = 60/a

-3*(1-9i^2) = 60/a

12 = 60/a

a = 5

Therefore, the polynomial f(x) = 5(x-3)(x-(1+3i))(x-(1-3i)) has the desired properties.
