Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Note ∠ Q is a right angle = 90°
Sum the angles and equate to 180
7b + 14 + 6b + 11 + 90 = 180, that is
13b + 115 = 180 ( subtract 115 from both sides )
13b = 65 ( divide both sides by 13 )
b = 5
Thus
∠ R = 6b + 11 = 6(5) + 11 = 30 + 11 = 41°
∠ S = 7b + 14 = 7(5) + 14 = 35 + 14 = 49°
∠ Q = 90°
In order to find out what the blank of your expression is,, we must solve for y. We can start doing this by distributing -2 through the parenthesis.
y - 4 = -2x - 6
Now you need to move the constant to the right side and change its sign.
y = -2x - 6 + 4
Calculate the sum of -6 + 4.
y = -2x - 2
Since we cannot simplify this down any further,, y is going to equal -2x - 2.
Let me know if you have any further questions.

Answer:
12,280
Step-by-step explanation:
just do 1456×5 :))
The answer
y=−x^2−2x-24 is like the form of y=ax² +bx +c, to find the vertex we use the formula:
the x intercept according to the vertex is x=-b/2a, and the vertex V is a point such that V [-b/2a, f(-b/2a)]
the x intercept is x= -(-2) / 2(-1) =-1, and f(-1)= -1 +2 -24= -23
the vertex is V(-1, -23)
B,C,D,A
Step-by-step explanation:
This is the right answer because -42 and 25 are the largest and -2/3 and 3/4 are the smallest. So the answer is B,C,D,A
