Statements Reasons
1. Write all the given as you did 1. Given
2. <DBA and <DBC are right angles 2. Def of perpendicular lines
3. m<DBA = 90 3. Def of right angle
m<DBC = 90
4. m<DBA = m<DBC 4. Substitution
5. m<DBA = m<1 + m<3 5. Angle addition postulate
m<DBC = m<2 + m<4
6. m<1 + m<3 = m<2 + m<4 6. Substitution
7. m<3 = m<4 7. Subtraction prop of equality
17/8 because you would multiple 2 times 8 then add one
The graph has the following key features:
(1) it shows the checking balance as a function of time (ie., at a given week)
(2) the graph is linear, showing a linear relationship between the balance and time. This is because the amount deposited is the same every week.
(3) the slope of the line is 134.12, since Terrance deposits $134.12 every week. The graph's y axis has different scale which makes the graph appear to have a slope close to 1, but, nevertheless, the linear function has slope of 134.12.
(4) the y-intercept is at 207.43 because at time 0 (week 0) there was a starting balance of $207.43
(5) The function in slope intercept form:
y = 134.12*x + 207.43
