Answer:
30degrees
Step-by-step explanation:
Given
Exterior angle m<CDE = 7x - 19 degrees
interior angles are
m<BCD = 2x - 1
m<DBC = x+10
Since the sum of the interior angles is equal to the exterior, hence;
2x - 1 + x+10 = 7x - 19
3x + 9 = 7x - 19
3x - 7x = -19 - 9
-4x = -28
x = 28/4
x = 7
Get m<CDE
m<CDE = 7x - 19
m<CDE = 7(7) - 19
m<CDE = 49 - 19
m<CDE = 30degrees
Answer:
n = 0
Step-by-step explanation:
1.2n + 1 = 1 - n
Add n and - 1 on both sides.
1.2n + n = 1 - 1
Combine like terms.
2.2n = 0
Divide both sides by 2.2.
n = 0
Answer:
(x,y)=(-10, -30)
Step-by-step explanation:
x/4 -y/12 = 0
--> x/4 = y/12
substitute into the first eq.
x/4 + y/12 = -5
y/12 + y/12 = -5
2y/12 = -5
y= (-5) * 12/2 = -30
solve for x, x/4 = (-30)/12
x=4* (-30)/12 = -10
Answer:
p: True, q: False, r: True
Step-by-step explanation:
Truth value only has two answer choices: true or false
p: True (there are 7 days in a week)
q: False (there are 31 not 30 days in March)
r: True (Halloween is on Oct. 31)
If not correct, write a message and I will try to help further.
The domain of a function is the set of values that are used as the x-coordinate.
As the parabola continues to go up and widen, all real numbers will be used as x-coordinates, so the domain is all real numbers.
