Answer:
Step-by-step explanation:
25x² + 1 = 5
25x² + 1 - 5 = 0
25x² - 4 = 0 By difference of two squares
(5x)² - (2)² = 0
(5x - 2)(5x + 2) = 0
5x - 2 = 0 or 5x + 2 = 0
5x = 0 + 2 5x = 0 - 2
5x = 2 5x = -2
x = 2/5 x = -2/5
x = 0.4 x = -0.4
x = + 0.4 or -0.4
Answer:1.75t + 3.50 ≤ 20
Step-by-step explanation:hope this helps :)
We know that
An ordered pair is used to locate a point on a coordinate grid.
The first number in an ordered pair is the
x-coordinate, and the second number in an ordered pair is the
y-coordinate.
In this problem, the ordered pair is

so
the x-coordinate is equal to

the y-coordinate is equal to

therefore
Rule N 1The y-value is

times the x-value
Rule N 2The y-value is

greater than the x-value
Both are possible because their solutions include the ordered pair listed
