Solve the system of linear equations by elimination. Check your solutions.

-5x + 3y = -6
9x - 4y = 1

Answers

Answer 1

We can divide both sides of the equation by 43 to solve for x:

90x / 43 - 47y / 43 = -49 / 43

x = -49/43

We can substitute this value for x back into either of the original equations to find y. Let's substitute it into the first equation:

-5x + 3y = -6

(-5 * -49/43) + 3y = -6

y = (-6 + 5 * 49/43) / 3

y = 17/43

The solution to the system of equations is (x, y) = (-49/43, 17/43).

To check our solution, we can substitute the values we found for x and y back into the original equations and see if they hold true.

In the first equation, -5x + 3y = -6, substituting the values we found for x and y gives us:

(-5 * -49/43) + (3 * 17/43) = -6

This simplifies to -6 = -6, which is true, so the solution holds for this equation.

In the second equation, 9x - 4y = 1, substituting the values we found for x and y gives us:

(9 * -49/43) - (4 * 17/43) = 1

This simplifies to -1 = -1, which is true, so the solution holds for this equation as well.

Therefore, the solution (x, y) = (-49/43, 17/43) is correct.

Answer 2
-5*9=-45
-45x+3*9y=-6*9
Equation1: -45x+27y=-54

Equation2: -45x-(4*(-5))y=1*(-5)
-45x+20y=-5

Equation1-equation2= 27y-20y=-54-(-5)
7y=-49
Y=-7

9x-4*(-7)=1
9x=1-28
X=-3

(X, y)=(-3, -7)

Answers

The first number 49 or larger that is divisible by 3 is 51 (17 * 3 = 51) so begin at 51 and count by 3's until you get to 95:51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93The first number 49 or larger that is divisible by 6 is 54 (6 * 9 - 54) so begin at 54 and count by 6's until you get to 95:54, 60, 66, 72, 78, 84, 90The first number 49 or larger that is divisible by 9 is 54 (9 * 6 - 54) so begin at 54 and count by 9's until you get to 95:54, 63, 72, 81, 90Now look for the numbers that are in all three lists

The only number that is a multiple of 3, 9, and 12 between 49 and 95 is 72

The point of a square pyramid is cut off, making each lateral face of the pyramid a trapezoid with the dimensions shown.

A trapezoid has a base of 3 inches, height of 1 inches, and top side length of 1 inch.

What is the area of one trapezoidal face of the figure?

Answers

The trapezoid face of a figure will also be known as the trapezoid area.

Trapezoid area formula:

(base1 + base2)/2 * height

Let’s plug in some values

(3 + 1)/2 * 1
(4)/2 * 1
2 * 1
2

The area of the trapezoidal face would be 2 in^2

janet bought a dress for $245. she recived a 15% discount vecause she is a loyal customer. in addition she recived another 10% off. calculate janets final bill​

Answers

$187.42 !!!!!!!!!!!!!!!!!!!!
First turn 15% into a decimal= .15
Multiply .15 * 245 =$36.75 ok that’s the first discount!

Second discount is 10% so turn 10% into a decimal (by dividing your percentage by 100) = .10
Multiply .10*245= $24.50 <- that’s your second discount

Ok now take both those answers and subtract them from her original $245 bill.

245-(24.50+36.75)= $183.75

Her final bill is $183.75
