2x = 8 - 5y
x = 8/2 - 5y/2
x = 4 - 2.5 y
or
x = 4 - 5/2 y
Answer:
about =502.65
Step-by-step explanation:
The interval notation given to us means that x is between negative infinity and 5, excluding both endpoints.
So we can write
which shortens to 
The graph will have an open hole at 5 on the number line, and shading to the left to indicate all points smaller than 5.
Answer:
x = 8
Step-by-step explanation:
A common Pythagorean Triple is a 3-4-5 triangle. The current triangle is 6-x-10. 6 is 2x3 and 10 is 2x5. THus the remaining side must be 2x4 or 8.
Answer: C. ∠SQP and ∠TQR
Step-by-step explanation:
Since, by the given diagram,
m∠TQR = m∠SQP (vertical angles)
And, m∠TQP < m∠TQR
By adding ∠TQR on both sides,
m∠TQP + m∠TQR < m∠TQR+m∠TQR
⇒m∠TQP + m∠TQR < 2 ∠TQR
⇒ 180° < 2 m∠TQR ( Because ∠TQP and ∠TQR are linear angles)
⇒ 90° < m∠TQR
Hence ∠TQR is a obtuse angle,
⇒ ∠SQP also is a obtuse angle.
