Answer: all of those or just number 2?
Step-by-step explanation:
And what app is that
- 9 ≤ x ≤ 7
the domain is the values of x on the x- axis that define y = f(x)
y is defined for all values of x in the stated domain
Hi!
Given:
Multiply both sides by 
<em>Notice the sign was flipped. This is because when you multiply or divide by a negative number, you must always flip the sign!</em>
<u>Now, for the graph:</u>
-------------------------------------------------------------------------------------------------------------
For < or > signs, it should be an open circle. For 
or 
signs, it should be closed.
Since 
is less than 6, it should go to the left. Since it's a < symbol, it should be open. Therefore your answer is B.
(looks like you were right!!)
Answer:
In ΔOPQ, \text{m}\angle O = (6x-14)^{\circ}
Step-by-step explanation:
Substitute the y in the 1st equation with the 2nd equation.
7x + 10(2x + 9) = 36
7x + 20x + 90 = 36
27x + 90 = 36
3x + 10 = 4
3x = -6
x = -2
So now we can find y.
y = 2x + 9 = 2(-2) + 9 = (-4) + 9 = 5.
So x = -2, y = 5.
