Is there supposed to be parentheses?
Answer:
B
Step-by-step explanation:
Since x varies directly as y, the ratio of x to y remains the same. Let the value of x when y=4 be a. Then we have
We can cross multiply to get that
Answer:
The slope of a line that has a y-intercept but no x-intercept will be zero.
Step-by-step explanation:
If the line has no x-intercept, then it never intersects the x-axis, so it must be parallel to the x-axis.
If a line does not have an x-intercept, it means it would never intersect the x-axis.
Thus, it must be parallel to the x-axis, meaning its slope will be zero. It would be just a horizontal line.
For example, y=9 is the line equation that does not have an x-intercept and its slope is zero.
Therefore, the slope of a line that has a y-intercept but no x-intercept will be zero.
Answer:
CD = 3.602019190339
Step-by-step explanation:
CD = DA - CA
DA = DB×Cos(29) = 18.7×cos(29) = 16.355388523507
BA = BA×cos(43) = 18.7×cos(43) = 13.676314220278
CA = BA÷tan(47) = 13.676314220278÷tan(47) = 12.753369333168
Then
CD = 16.355388523507 - 12.753369333168 = 3.602019190339
