What are the solution of a quadratic equation 49x^2 = 9​

Mathematics
1 answer:
kozerog [31]3 years ago
3 0

Answer:

x = ±3/7

Step-by-step explanation:

49 x^2 = 9

Divide each side by 49

49/49  x^2 = 9/49

x^2 = 9/49

Take the square root of each side

sqrt(x^2) = ±sqrt(9/49)

We know  sqrt(a/b) =sqrt(a)/sqrt(b)

x = ±sqrt(9)/ sqrt(49)

x = ±3/7

Write an equation for the line that is parallel to the given line and passes through the given point
Evgesh-ka [11]

Answer:

y = 2x + 2

Step-by-step explanation:

The equation ofa line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 4 ← is in slope- intercept form

with m = 2

Parallel lines have equal slopes , thus

y = 2x + c ← is the partial equation

To find c substitute (3, 8) into the partial equation

8 = 6 + c ⇒ c = 8 - 6 = 2

y = 2x + 2 ← equation of parallel line
