Answer:
The answer is the first one ⇒ AAS
Step-by-step explanation:
∵ DB ⊥ AC
∴ m∠DBA = m∠DBC = 90° ⇒ (1)
∵ m∠A = m∠C ⇒ (2) given (from figure)
∵ DB is a common side in the two Δ ⇒ (3)
From (1) , (2) and (3)
∴ Δ ABD is congruent to Δ CBD ⇒ AAS
Answer: Upper left corner
Explanation:
The error happens in step 2. Notice that x is <u>not</u> part of the second term 16, so there's no way to factor x from it unless you want a fraction to result.
The second step should be 8(4x-2)
Another way to factor is to say 16(2x-1)
Answer:
c = 8
Step-by-step explanation:
Given the following data;
Slope, m = -2
Points (x, y) = (5, -2)
To find the intercept, c;
Equation of a straight line is given by the formula: y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
Substituting the values in order to find the intercept, we have;
-2 = -2(5) + c
-2 = -10 + c
c = 10 - 2
c = 8
Therefore, the y-intercept is 8.
pool I would like that, I love u dude
Y > x
y = 2(3+x)
y = 3x-2
------------------------------
2(3+x) = 3x-2
2(3+x) - (3x-2) = 0
6 + 2x -3x + 2 = 0
8 -x = 0
x = 8
---------------------------
y = 2(3+x) = 2(3+8) = 22
y = 3x-2 = 3*8 -2 = 22
----------------------------------
x = 8 ; y = 22
