If im correct the answer would be 4, hope i could help out.
Answer:
A = (C - By)/x
Step-by-step explanation:
Ax + By = C
Subtract By from each side
Ax + By -By= C-By
Ax = C-By
Divide each side by x
Ax/x = (C - By)/x
A = (C - By)/x
Answer:
2. 40
3. 40
4. 140
5. 140
6. 40
7. 40
8. 140
Step-by-step explanation:
angles 2 (and 3) are supplementary angles of the given angle, this means that the given angle and either one of the two angles i just mentioned should add up to 180
angle 4 is vertical to the given, so this means that they are congruent
angle 8 corresponds to 4 and 5 corresponds to the given, so they are all congruent
angles 7 and 6 correspond to 3 and 2, so they are also 40
The y-intercept in the equation in the form y = mx + b is b.
To find the y-intercept in x - y = -1, isolate y on the left-hand side:
x - y = -1
-y = -x - 1
y = x + 1
b in this equation is 1, so the y-intercept is 1.
Hope this helps.
