Answer:
Step-by-step explanation:
Note that this function resembles the absolute value function y = |x|.
The graph of y = |x| has its vertex at (0, 0) and opens up in a v-shape.
The graph of y = |x - 2| looks the same as that of y = |x|, but the entire graph has been translated 2 units to the right.
The graph of y = |x - 2| + 4 is that of y = |x - 2|, translated 4 units up.
2x + y = 20
y = 20 - 2x
Substitute into second equation:
6x - 5(20-2x) = 12
6x -100 +10x = 12
16x = 112
x = 7
Plug back into first equation:
2(7) + y = 20
14 +y = 20
y = 6
Answer is x = 7 and y = 6
Answer:
Step-by-step explanation:
Id QS bisects angle PQR, then <PQS = <SQR and <PQS+<RQS = <PQR
The formula then becomes
<PQS+<PQS = <PQR
2<PQS = <PQR
<PQS = <PQR/2
Given <PQR = 119°
Substitute into the resulting expression above;
<PQS = <PQR/2
<PQS = 119/2
<PQS = 59.5°
Since <RQS = <PQR, hence <RQS is also 59.5°
It should be -
x = 53
y = 90
w = 53
z = 37
