Step-by-step explanation:
Given

Graph the solution
Multiply both sides by 3
<em>See attachment for graph (Assume T is on the x-axis)</em>
4x + 10= 2x - 6
Subtract 2x on both sides
4x - 2x + 10 = 2x - 2x - 6
4x - 2x + 10 = -6
2x + 10 = -6
Subtract 10 on both sides
2x + 10 - 10 = -6 - 10
2x = -6 - 10
2x = -16
x = -8
1) This question is asking for the linear equation of the data in the table.
Remember a linear equation in slope-intercept form for this problem is something like a = cm + b, where c = the slope of the equation, b = the y intercept,
and m and a are your variables (and values in the table).
This might be confusing if you haven't learned it! Don't worry, all you need to know is the equation and just plug in values to find b (since that's the number that different in all your answer choices).
2) All your answer options have the same slope, c = -4000. All you want to find is the value of b, the y-intercept.
This value you can find by plugging in a set of values from the table into your equation, knowing c = -4000. Let's plug in the first row of values: m = 1, a = 35000.
a = cm + b
a = -4000m + b
35000 = (-4000)(1) + b
35000 = -4000 + b
39000 = b
3) That means b = 39000. Put b = 39000 and c = -4000 together into your equation a = cm + b to get your final equation:
a = cm + b
a = -4000m + 39000
That is answer choice B.

Answer: B) -4000m + 39000
Answer:
Question 1: they are vertically opposite angles
Question 2:they are supplementary angles
Question 3:they are vertically opposite angles
Question 4:they are complementary angles
Step-by-step explanation:
Question 1:
a° and b° are vertically opposite angles so they are equal
Question 2:
a° and b° are supplementary angles,since their sum is equal to 180°
Question 3:
a° and b° are vertically opposite angles so they are equal
Question 4:
a and b are complementary angles,their sum is equal to 90°
