Find the solution to the system of equations

Neko [114]

Answer:

x=1

y=-4

Step-by-step explanation:

Since -x-3=y subsitue that in at the top equation

$- x - 3 = - 7x + 3$

$- x = - 7x + 6$

$6x = 6$

$x = 1$

Plug x=1 back into the equation to solve for y.

$y = - 7(1) + 3$

$y = - 4$

erastovalidia [21]

Answer:

Model A is 9

Model B is 5

Step-by-step explanation:

At Lisa's printing Company LLC there are two kinds of printing presses model.

Let x = the number of model A printing press.

Let y = the number of the model B printing press.

model A can print 70 bucks per day and model B can print 55 bucks per day.

The total number of both models prints 905 bucks per day.

This means

70x + 55y = 905 - - - - - - - - -1

The company owns 14 total printing presses. This means

x + y = 14 - - - - - - - - - -2

x = 14-y

Put x = 14-y in equation 1

70(14-y) + 55y = 905

980 -70y + 55y = 905

-15y = 905-980= -75

y = -75 / -15= 5

x = 14-y = 14-5

= 9

△ABC is a right triangle. m∠A = 32° m∠B=90°; AC = 9 and AB=5. Choose the expression used to find BC?

Westkost [7]

Answer:

Step-by-step explanation:

The diagram of the right angle triangle is shown in the attached photo.

From the given right angle triangle,

AC represents the hypotenuse of the right angle triangle.

With m∠32 as the reference angle,

BC represents the adjacent side of the right angle triangle.

AB represents the opposite side of the right angle triangle.

To determine BC, we would apply

the Sine trigonometric ratio which is expressed as

Sin θ= opposite side/hypotenuse. Therefore, the expression used to find BC is

Sin 32 = BC/9

BC = 9Sin32
