A
given the 2 equations
2x + y = - 2 → (1)
x + y = 5 → (2)
subtract (2) from (1) term by term to eliminate y
(2x - x ) + (y - y ) = (- 2 - 5 )
x + 0 = - 7 ⇒ x = - 7
substitute x = - 7 in either of the 2 equations and solve for y
(2) : - 7 + y = 5 ( add 7 to both sides )
y = 5 + 7 = 12 → A
Answer:
squareroot of 7 < 14/5
Step-by-step explanation:
We are given that two real numbers
squareroot of 7 and 14/5
We have to compare the given two real numbers and fill the mathematical symbol in the blank
In order to compare the given real number we will find the value of given real numbers .
Value of squareroot of 7 = 2.646
Value of 14/5 = 2.8
Value of 2.645 is less than 2.8.
Hence, squareroot of 7 is less than 14/5
hope i helped! :D

Answer:
C. It has been stretched horizontally.
Step-by-step explanation:
According to the diagram, the parabola has not been reflected in any way, nor has it been translated, since the parabola is pointing up in a smile, and the vertex is still at the origin.
The parabola does appear to be stretched, since the parent function had points at (1, 1), and (2, 4), but this parabola does not contain those points.
Since the parabola appears to be flatter than the parent function, we can say that C. It has been stretched horizontally.
Hope this helps!
