An equation is formed of two equal expressions. The value of x and y is 17 and 20, respectively. Thus, the correct option is D.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Solving the first equation for y,

4x - 3y = 8

-3y = 8 - 4x

y = (8-4x)/(-3)

Solving the second equation for y,

5x - 4y = 5

-4y = 5 - 5x

y = (5 - 5x)/(-4)

Equate the value of y,

y = y

(8-4x)/(-3) = (5 - 5x)/(-4)

-32 + 16x = -15 + 15x

16x - 15x = -15 + 32

x = 17

Substitute the value of x in any one of the equation,

4x - 3y = 8

4(17) - 3y = 8

68 - 3y = 8

-3y = -60

y = 20

Hence, the value of x and y is 17 and 20, respectively. Thus, the correct option is D.

Answer:

D. the slope of f(x) is greater than the slope of g(x)

Step-by-step explanation:

slope of f(x) =rise/run

=y2 -y1 / x2 -x1

slope of f(x)= -1-2/1-0= -3

g(x)= -5x-6

slope of g(x)= -5

-3>-5

D. the slope og f(x) is greater than the slope of g(x)

  \dfrac{19}{15}\,\text{radians}=1.2\overline{6}\,\text{radians}

Step-by-step explanation:

θ = 228° = (228°)×(π/180° radians/degree) = 228/180 radians

  = 19/15 radians

  ≈ 1.266...(repeating) radians

Help please I neeed help
Whitepunk [10]

Answer:

D

Step-by-step explanation:

f(x) would be -2x + 3 because the y-intercept is 3 and the slope is -2.

Slope: (3 - 1)/(0 - 1) = -2

The slope of g(x) is -7.

-2 > -7

it takes 8 labours 6days to complete a certain job.how many labours would complete the job in 15 days.​
VashaNatasha [74]

Answer:

Step-by-step explanation:

Required man days to complete the job = 8 * 6

                                                                   = 48 Man Days

Required labors to complete the job by 15 days = 48/15

                                                                               = 3.2

It means, it is required 4 labors can complete the certain work by 15 days
