Answer:
Answer:
-3x+5y=20
Step-by-step explanation:
Standard form is given by ax+by=c
where a , b and c are integers
here we have an equation
so we first multiply the complete equation by 5 to get rid of the fraction
Now subtract 3x from both side to get the required standard form
-3x+5y=20
Step-by-step explanation:
just move y to the side with x and move 4 to the other end
Answer:
239.99 x 75%(75/100) $180
$180 x 90%(90/100) = $162
Step-by-step explanation:
The value of x is x=2.57338 and x=−0.906718
<h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given:
3x²-5x-7=0
Using the discriminant method,
a = 3, b = -5, and c = -7
x= -b± √b²-4ac / 2a
x= 5 ± √25 + 84/ 6
x= 5± √ 109
Hence, x=2.57338 and x=−0.906718

Answer: trivial solution is the only solution to Ax = 0, therefore columns must be linearly independent.
Step-by-step explanation: Recall that the columns of A are linearly independent if and only Ax = 0 had only the trivial solution. Since Ax = b has at most one solution, therefore the only solution to Ax = 0 is the trivial solution and the column vectors must be linearly independent.
The path is the hypotenuse of a right triangle with legs 30 and 120.
30² + 120² = c²
900 + 14400 = c²
15300 = c²
c=√15300 ≈123.7'
instead of walking 30+120=150 feet they save 26.3 feet by taking the shortcut
