Answer: 1/2

Step-by-step explanation:

Answer:

1 and 1/2

Step-by-step explanation:

Let -4x - 15y = 17 be known as equation 1 and -x + y = -13 as equation 2.

To solve the system of equations, we need to determine the value of the "x" and "y" variables. Let us start by determining the value of the y variable.

Note: Since the second equation looks easier to solve for y (in my opinion), I will determine the value of y in the second equation.

This can be done by isolating y on one side of the equation.

Equation 2: [tex]\bold{-x + y = -13}[/tex]

Add "x" on both sides of the equation:

[tex]\implies -x + y = -13[/tex]

[tex]\implies -x + y + x = -13 + x[/tex]

[tex]\implies y = -13 + x[/tex]

Therefore, the value of y is -13 + x. Let us substitute the value of y, obtained from equation 2, into equation 1 to determine the value of x.

Equation 1: [tex]\bold{-4x - 15y = 17}[/tex]

Substitute the value of y in the equation:

[tex]\implies 4x - 15y = 17[/tex]

[tex]\implies -4x - 15(-13 + x) = 17[/tex]

Simplify the distributive property:

[tex]\implies -4x - 15(-13 + x) = 17[/tex]

[tex]\implies -4x + (195 - 15x) = 17[/tex]

[tex]\implies -4x + 195 - 15x = 17[/tex]

Combine like terms on both sides:

[tex]\implies -4x + 195 - 15x = 17[/tex]                                         

[tex]\implies -19x + 195 = 17[/tex]                                                                

Subtract 195 on both sides of the equation:                      

[tex]\implies -19x + 195 = 17[/tex]                                                                    

[tex]\implies -19x + 195 - 195 = 17 - 195[/tex]                                    

[tex]\implies -19x = -178[/tex]                                                                        

Divide -19 on both sides of the equation:                        

[tex]\implies -19x = -178[/tex]                                                                

[tex]\implies \dfrac{-19x}{-19} = \dfrac{-178}{-19}[/tex]                                                      

[tex]\implies \bold{x = \dfrac{178}{19} }[/tex]                                                                        

Now, substitute the value of x in -13 + x to determine the value of y. Once determined, we can put the solution in (x, y) form.

[tex]\implies y = -13 + x[/tex]

[tex]\implies y = -13 + \dfrac{178}{19}[/tex]          

[tex]\implies y = \dfrac{-247}{19} + \dfrac{178}{19}[/tex] 

[tex]\implies \bold{y = \dfrac{-69}{19} }[/tex]

∴ Solution ⇒ (x, y) ⇒ (178/19, -69/19)

Therefore, the solution to the following system of equations is (178/19, -69/19)

Answer: Y=-1/4x

Step-by-step explanation:

A good way to find an equation of a line is to look for the slope. An obvious spot on this line would be when it crosses (0,0), and another one to the right would be when it crosses at (4,-1).

The slope is rise over run, or if we use the two points we found, "rise" would be -1, because it's dropping 1 unit when going from (0,0) to (4,-1), and the "run" would be 4, because it moves to the right 4 from (0,0) to (4,-1).

Putting these two values together we get:

m (slope) = rise / run

m = -1 / 4

Out of all the equations we're given, we can look for the one with a slope of -1/4, which is given to us:

y = (-1/4)x

Answer:

15/20 cups of cranberry juice

Step-by-step explanation:

3/5 cranberry juice makes 12

12/2=6

3/5= 0.3

6/2=3

0.3/2= 0.15

0.15 = 3/20

3/20 cranberry juice makes 3 servings.

add 3 and 12 to make 15 servings, add 3/5 and 3/20.

3/5= 12/20

12/20 + 3/20 = 15/20 cups of cranberry juice

Answer:

The average price of the stock over the first six years is 56.669 US dollars.

Step-by-step explanation:

Since the price is a continuous and differentiable function, we can determine the average price by means of the following integral equation:

[tex]\bar S = \frac{1}{t_{F}-t_{O}}\cdot \int\limits^{t_{F}}_{t_{O}} {S(t)} \, dt[/tex] (1)

Where:

[tex]t_{O}[/tex] - Initial time, measured in years.

[tex]t_{F}[/tex] - Final time, measured in years.

If we know that [tex]t_{O} = 0\,yr[/tex], [tex]t_{F} = 6\,yr[/tex] and [tex]S(t) = 46+12\cdot e^{-0.04\cdot t}[/tex], then the average price of the stock over the first six years is:

[tex]\bar S = \frac{46}{6-0} \int\limits^6_0 dt +\frac{12}{6-0}\int\limits^6_0 {e^{-0.04\cdot t}} \, dt[/tex]

[tex]\bar S = \frac{23}{3}\cdot t|\limits_{0}^{6}-\frac{2}{0.04}\cdot e^{-0.04\cdot t}|_{0}^{6}[/tex] (2)

[tex]\bar S = \frac{23}{3}\cdot (6-0)-\frac{2}{0.04}\cdot [e^{-0.04\cdot (6)}-1][/tex]

[tex]\bar S = 56.669\,USD[/tex]

The average price of the stock over the first six years is 56.669 US dollars.

Answer:

A. (-5, 0) and (1, -3)

B. Slope (m) = -½

C. y + 3 = -½(x - 1)

D. y = -½x - ⁵/2

E. ½x + y = ⁵/2

Step-by-step explanation:

A. Two points on the line from the graph are: (-5, 0) and (1, -3)

B. The slope can be calculated using two points,(-5, 0) and (1, -3):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 - 0}{1 -(-5)} = \frac{-3}{6} = -\frac{1}{2} [/tex]

Slope (m) = -½

C. Equation in point-slope form is represented as y - b = m(x - a). Where,

(a, b) = any point on the graph.

m = slope.

Substitute (a, b) = (1, -3), and m = -½ into the point-slope equation, y - b = m(x - a).

Thus:

y - (-3) = -½(x - 1)

y + 3 = -½(x - 1)

D. Equation in slope-intercept form, can be written as y = mx + b.

Thus, using the equation in (C), rewrite to get the equation in slope-intercept form.

y + 3 = -½(x - 1)

2(y + 3) = -1(x - 1)

2y + 6 = -x + 1

2y = -x + 1 - 6

2y = -x - 5

y = -x/2 - ⁵/2

y = -½x - ⁵/2

E. Convert the equation in (D) to standard form:

y = -½x - ⁵/2

½x + y = ⁵/2
