8x+y=9, 33y+6x=190, what is the value of x and y?

Answers

Answer 1

Answer:

x = 0.414729

y = 5.6822

Step-by-step explanation:

We can solve this by either of two mwethods: Solve the equations directly, or graph them to find the point they intersect (the only solution that satisfies both equations).

SOLVE

33y+6x=190

8x+y=9

y = 9-8x

Substitute this value of y in the first equation:

33y+6x=190

33(9-8x)+6x=190

297-264x+6x=190

-264x+6x=190-297

-258x = -107

x = (107/258)

x = 0.414729 Use this value of x to solve for y (in either equation)

8x+y=9

8(0.414729)+y=9

3.317829 + y = 9

y = 5.6822

======

GRAPH:

Plot the two equations and find where they intersect.

A line that passes trough the point (7,3) with slope of -1 ( answer plesse I need help )

Answers

Answer:

Slope-Intercept Form:

The equation of a line in slope-intercept form is y=mx+b. Since we know that the slope is -1, the equation so far is y=-x+b. To find the value of b, substitute in the given point.

3=-7+b

Add 7 to both sides.

10=b

The equation of the line is slope intercept form is y=-x-10.

Point-Slope Form:

The equation of a line in point-slope form is y-y1=m(x-x1). Substituting in the given point and slope, the equation is y-3=-(x-7).

Hope this helps! :)

Answer:

y= -x + 10

Step-by-step explanation:

3 = -1(7) + b

3 = -7 + b

10 = b

Since the slope is -1, that means it's just -x

So y = -x + 10

A car and a van start driving from the same location. The car drives at 40 miles per hour, and the van drives at 52 miles per hour. After 7 hours, how far apart are the car and the van?

WILL MARK BRAINLY NO BOTS!!!

Answers

Answer:

84 Miles

Step-by-step explanation:

The car drove 40 miles per hour for 7 hours so the car traveled 40X7 which is 280 miles and the van traveled at 52 miles per hour for 7 hours so the van traveled 52X7 which is 364 miles so the difference between both is 84 miles.

Answers

Answer:

-4 2

Step-by-step explanation:

Because the sign in the inequalities is only greater than/ less than (not equal to), we know that there is an open dot on x=-4 and on x=2.

From there, we shade the area on the graph that is true to the function. So, we can test points.

First we will test x=-5

-5<-4 --> this is true, so we will shade to the left of x=-4

Now test x=0

0<-4 --> this is false

0>2 --> this is also false, so the area between the two open dots will not be shaded

Now test x=3

3>2 --> this is true, so we will shade to the right of x=3

The function f(x) =59(x − 32) can be used to determine the temperature in °C when the temperature is x°F. Find the inverse function that can be used to determine the temperature in °F when the temperature is x°C.

Answers

Answer:

[tex]F = ( \frac{9}{5}C ) + 32[/tex]

with F = xF and C = xC

=> f(x) = (9/5)x + 32

I'm sorry I can't mark the degree symbol

Step-by-step explanation:

[tex]f(x) = \frac{5}{9}(x-32) \\xC = \frac{5}{9}(xF-32) \\xC * \frac{9}{5} = \frac{5}{9}(xF-32) * \frac{9}{5} \\xC * \frac{9}{5} + 32 = xF - 32 + 32 \\\\xC * \frac{9}{5} + 32 = xF[/tex]

A smokestack deposits soot on the ground with a concentration inversely proportional to the square of the distance from the stack. With two smokestacks d miles apart, the concentration of the combined deposits on the line joining them, at a distance x from one stack, is given by:
[tex]S=\frac{c}{x^2} +\frac{k}{(d-x)^2}[/tex]
where c and k are positive constants which depend on the quantity of smoke each stack is emitting. If k=8c, find the point on the line joining the stacks where the concentration of the deposit is a minimum. xmin= ? miles

Answers

Answer:

d/3

Step-by-step explanation:

For k = 8c, the concentration is ...

S = c/x^2 + 8c/(d -x)^2

The minimum of the function will be found where its derivative is zero. The derivative with respect to x is ...

S' = -2c/x^3 +(-2)(8c)(-x)/(d -x)^3

We are interested in the value of x that makes this zero.

0 = -2c/x^3 +16c/(d -x)^3 . . . . . simplify slightly, set S'=0

0 = (-2(d -x)^3 +16x^3)/(x(d -x))^3 . . . . . combine terms, divide by c

0 = d^3 -3d^2x +3dx^2 -x^3 -8x^3 . . . . multiply by (x(d-x))^3/(-2)

9x^3 -3dx^2 +3d^2x -d^3 = 0 . . . . . simplified cubic

Factoring by grouping, we have ...

(9x^3 -3dx^2) +(3d^2x -d^3) = 0

3x^2(3x -d) +d^2(3x -d) = 0

(3x^2 +d^2)(3x -d) = 0

The solution will be found where the second of these factors is zero:

3x -d = 0

x = d/3

The concentration of the deposit is a minimum at x = d/3 miles.

The graph shows the minimum is x = 1/3 when d = 1.

The equation
N(t) = 400/1 + 39e−0.7t models the number of people N in a town who have heard a rumor after t days.

How many people started the rumor?

Answers

Functions can be represented as equations, and equations can be represented as functions.

The number of people that started the rumor is 10

The function is represented as:

[tex]\mathbf{N(t) = \frac{400}{1 + 39e^{-0.7t}}}[/tex]

To calculate the number of people that started the rumor, we simply set t to 0.

So, we have:

[tex]\mathbf{N(0) = \frac{400}{1 + 39e^{-0.7 \times 0}}}[/tex]

Evaluate the exponent of e

[tex]\mathbf{N(0) = \frac{400}{1 + 39e^{0}}}[/tex]

Express e^0 as 1

[tex]\mathbf{N(0) = \frac{400}{1 + 39\times 1}}[/tex]

Multiply 39 and 1

[tex]\mathbf{N(0) = \frac{400}{1 + 39}}[/tex]

Add 1 and 39

[tex]\mathbf{N(0) = \frac{400}{40}}[/tex]

Divide 400 by 40

[tex]\mathbf{N(0) = 10}[/tex]

When t = 0, N(t) = 10

This means that 10 people started the rumor.

Hence, the number of people that started the rumor is 10

A board is 65 inches long into two pieces, so that one piece is 7 inches shorter than twice the length of the other pieces. Find the length of two pieces

Answers

Answer: 24 in, 41 in

Step-by-step explanation:

Set shorter piece is x in, and another longer one is y.

1. x + y = 65

2. y = 2x - 7

plug in the second equation into y of the first equation, we get:

x + (2x - 7) = 65

x + 2x - 7 = 65

3x - 7 = 65 （Add 7 to the both side)

3x = 72 (Divide 3 to both side)

x = 24 in

Plug x in the second equations to slove y.

y = 2x - 7

y = 2(24) - 7

y = 41 in

Aaliyah is deciding between two parking garages. Garage A charges an initial fee of $8 to park plus $2 per hour. Garage B charges an initial fee of $4 to park plus $3 per hour. Let AA represent the amount Garage A would charge if Aaliyah parks for tt hours, and let BB represent the amount Garage B would charge if Aaliyah parks for tt hours. Graph each function and determine the interval of hours parked, t,t, for which Garage A is cheaper than Garage B.

Answers

The interval of hours for which Garage A is cheaper than Garage B is t > 4.

Let A represent the amount Garage A would charge if Aaliyah parks for t hours, and let B represent the amount Garage B would charge if Aaliyah parks for t hours.

Garage A charges an initial fee of $8 to park plus $2 per hour. Hence:

A = 2t + 8

Garage B charges an initial fee of $4 to park plus $3 per hour. Hence:

A = 3t + 4

For Garage A to be cheaper than Garage B:

2t + 8 < 3t + 4

8 - 4 < 3t - 2t

4 < t

t > 4

The interval of hours for which Garage A is cheaper than Garage B is t > 4.
