What is the solution to the following system of equations
5x + 4y = 40 6x + 4y =44

Answers

Answer:

X=4, y=5

Step-by-step explanation:

5x + 4y =40 equation 1

6x + 4y =44 equation 2

-1(5x + 4y)=-1(40) multiply equation 1 by -1 so equation will eliminate y

-5x - 4y=-40 modif equation 1

6x + 4y= 44  equation 2

         x=4.     Add above 2 equations

solve for y:

5x + 4y =40

5(4)+4y=40

20+4y =40

4y=20

y=5

check solution ;

6x+4y=44

6(4) + 4(5)=44

24 + 20=44

44=44

Answers

Step-by-step explanation:

If the function m not-equals 0 has an inverse function, which statement must be true? B not-equals 0

Answers

Answer:

Option a: m ≠ 0

Step-by-step explanation:

After a small online search, I've found that the complete question is:

If the function f(x) = m*x + b has an inverse function, which statement must be true?

a) m ≠ 0

b) m = 0

c) b ≠ 0

d) b = 0

Ok, if g(x) is an inverse of the function f(x), then:

g( f(x)) = x

f( g(x)) = x

Let's assume that f(x) = m*x + b  has an inverse, and this inverse function is g(x).

Because f(x) is linear, g(x) is also linear, then:

g(x) = n*x + c

Let's find the values of A and B.

We know that:

f( g(x)) = x =  m*(n*x + c) + b

then

x = m*n*x + m*c + b

Then we must have:

m*n = 1

(m*c + b)  = 0

From the first equation m*n = 1

We get:

n = 1/m

The slope of the inverse function is one over the slope of the original function.

Because m is on the denominator, m can not be equal to zero (because a division by zero is not defined)

Then the correct option is the option a, m ≠ 0.

Step-by-step explanation:

n= 52

Hello

Answer:

n=52

Step-by-step explanation:

n-24=28

n=24+28

n=52

You solve n by adding 24 to both sides to get n by itself which is n= 24+28. After you add 24 and 28 together you get 52. So n=52.

help me with this math question please I'm giving away brainliests​

Answers

Answer:

Step-by-step explanation:

Given function in the question is,

[tex]f(x)=\frac{-2x^2-4x}{4x+8}[/tex]

       [tex]=\frac{-2x(x+2)}{4(x+2)}[/tex]

       [tex]=-\frac{1}{2}x[/tex] If [tex]x\neq -2[/tex]

Given function is not defined at x = -2

At x = -2,

[tex]f(-2)=\frac{1}{2}(2)[/tex]

          [tex]=1[/tex]

Therefore, there is a hole in the graph at (-2, 1).

Graph of the function 'f' will be a straight line with a hole at (-2, 1).

Horizontal asymptote → None

Vertical asymptote → None

x-intercept → No x-intercept [Line passes through origin (0,0)]

y-intercept → No y-intercept [Line passes through origin (0,0)]

Hole → (-2, 1)

(3; -17) (-3;13 )

plz help

Answers

Answer:

Slope-intercept form of the line:

y = mx + b

Point-slope form of the line:

y - y1 = m(x - x1)

------------------------------------

Points:

(2;9) (4,17)

The slope:

m = (17 - 9)/(4 - 2) = 4

The line:

y - 9 = 4(x - 2)y = 4x - 8 + 9y = 4x + 1

----------------------------------

Points:

(3; -17) (-3;13 )

The slope:

m = (13 - (-17)) / (-3 - 3) = 4/ -6 = -2/3

The line:

y - (-17) = -2/3(x - 3)y = -2/3x + 2 - 17y = -2/3x - 15

Let the vector \mathbf{v}v have an initial point at (-5, -5)(−5,−5) and a terminal point at (-3, 1)(−3,1). Determine the components of vector \mathbf{v}.V.

Answers

Answer:

The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.

Step-by-step explanation:

The components of the vector is equal to the vector position of the terminal point relative to the initial point ([tex]\vec v[/tex]), that is:

[tex]\vec v = B(x,y) - A(x,y)[/tex] (1)

Where:

[tex]A(x,y)[/tex] - Initial point.

[tex]B(x,y)[/tex] - Terminal point.

If we know that [tex]A(x,y) = (-5,-5)[/tex] and [tex]B(x,y) = (-3,1)[/tex], then the vector is:

[tex]\vec v = (-3,1) -(-5-5)[/tex]

[tex]\vec v = (2, 6)[/tex]

The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.
