Add the two rows together
3x = 12
Solve for x in the above equation
x = 4
Substitute x = 4 into any of the two equations above. Let's choose the first one; 2x - y = 6
2 × 4 - y = 6
Solve for y in the above equation
y = 2
Thus,
<u>x = 4</u>
<u>y = 2</u>
The slope-intercept form:
y = mx + b
m - slope
b - y-intercept
We have the line y = 2x - 5.
The parallel lines have the same slope. Therefore we have y = 2x + b.
Put the coordinates of the point B(8, 6) to the equation:
6 = 2(8) + b
6 = 16 + b <em>subtract 16 from both sides</em>
-10 = b → b = -10
The equation of a line: y = 2x - 10.
Put the coordinates of the point A(n, 4) to the equation:
4 = 2(n) - 10 <em>add 10 to both sides</em>
14 = 2n <em>divide both sides by 2</em>
<h3>7 = n → n = 7</h3>
Answer:
25.35
Step-by-step explanation:
390 × 6.5% = 25.35
Answer:
A two story home might use translation to have both floors identical and most homes have windows of the same size and shape so they might also use translation. Sometimes buildings use reflection to make rooms opposite each other the same.
