X + y = k

1 answer:

5 0

X + y = k
x - y = k Add these two equations.
2x = 2k Divide both sides by 2
2x/2 = 2k/2
x = k

x + y = k
k + y = k Subtract k from both sides.
y = 0

Answer:

2) $x - y = \frac{2}{3}$

$= > x = \frac{2}{3} + y = \frac{2 + 3y}{3}$

3) $3x + 2y = 6$

$= > 3x = 6 - 2y$

$= > x = \frac{6 - 2y}{3}$

4) $\frac{1}{4} x + y = 2$

$= > y = 2 - \frac{x}{4} = \frac{8 - x}{4}$

5) $4x - 3y = - 33$

$= > 3y = 4x + 33$

$= > y = \frac{4x + 33}{3}$

4k - 6 < 3k + k - 1 Solve for K

djverab [1.8K]

Step-by-step explanation:

4k - 6 < 3k + (k - 1)

4k < 3k + 6(k - 1)

4k < 3k + 6k - 6

4k < 9k - 6

4k - 9k < -6

-5k < -6

k < -6

-5

k < 6

Find the area of the figure.

34kurt

Hello from MrBillDoesMath!

Answer:

89 square meters

Discussion:

The area of the figure is the area of the full rectangle minus the area of the triangle .

Rectangle area = 13 * 8 = 104

Triangle area = 1/2 bh = 1/2 ( 13 - 4 -4) * 6 = 1/2(5)*6 = 15

So the area of the figure - 104 = 15 = 89

Two angles are complementary. If one of the angles measures 57 degrees, how much does the other angle measure?

cricket20 [7]

The answer is 33. Remember all complimentary angles equal 90 degrees so subtract 90 from 57 and the other angle is 33
