Answer:
Step-by-step explanation:
Given equation:
Equation:1
Equation:2
Multiplying equation:2 by 2 gives:
Equation:3
Subtracting Equation:3 from Equation:1
The negative sign outside the bracket changes the sign inside it after opening the bracket
Putting the value of 'y' in Equation:2
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
solve the inequality
The solution is the interval----------> (-∞,6]
All real numbers less than or equal to
The solution of the inequality is the shaded area to the left of the solid line
see the attached figure
Triangle QST is an isosceles triangle. You can tell because two of the legs are congruent. Thus angle T is also an x-variable.
Add all of the degrees together, set them equal to 180 and solve for x.
x + x + 74 = 180
2x + 74 = 180
2x = 180 - 74
2x = 106
x = 53
This rules out options C and D.
Now we have to find angle PQS:
The measurements of triangle PQR are congruent to each other so 180 / 3 = 60 they are all 60 degrees.
Angles PQR, PQS, and SQT are in line with each other so they add up to 180.
60 + PQS + 74 = 180
134 + PQS = 180
PQS = 180 - 134
PQS = 46
Triangle PQS is another isosceles triangle. Thus, the two base angles are the same. We are going to add them together plus y and set it all equal to 180 to solve.
46 + 46 + y = 180
92 + y = 180
y = 180 - 92
y = 88
x = 53, y = 88. Your answer is option B
C because there both equal. its just that the other one doesn't have a 0 on the end but there equal.
