Isosceles trapezoid ABCD has legs and and base , If AB = 7y – 4, BC = 4y – 6, and CD = 8y – 18, find the value of y.
Answers
AB = CD
AB = 7 y - 4, CD = 8 y - 18
8 y - 18 = 7 y - 4
8 y - 7 y = 18 - 4
Answer:
y = 14
Answer:
y= 14
Step-by-step explanation:
Isosceles trapezoid has opposite sides equal
Hence, AB and CD are equal
We have been given AB= 7y-4
And CD= 8y-18
According to the property
7y-4 = 8y-18
On simplification:
7y -8y= -18+4
On further simplification.
-y=-14
Hence, y =14

Answer:
After 12.86 days Nick and Perry will have the same amount of money
Step-by-step explanation:
Perrie's can be expressed as;
Total amount Perry will have after t days=Initial amount Perry has-Total amount Perry spends
where;
Initial amount that Perry has=$180
Total amount Perry spends=Amount he spends per day×Number of days=(6×t)=6t
Replacing in the expression;
Total amount Perry will have after t days=(180-6t)
Nick's can be expressed as;
Total amount Nick will have after t days=Initial amount Perry has+Total amount Nick earns
where;
Initial amount that Nick has=$0
Total amount Nick earns=Amount he earns per day×Number of days=(8×t)=8t
Replacing in the expression;
Total amount Nick will have after t days=(0-8t)=8t
Equating Total amount Nick will have after t days to Total amount Perry will have after t days;
180-6t=8t
180=(8t+6t)
14t=180
t=(180/14)=12.86 days
After 12.86 days Nick and Perry will have the same amount of money

Final Answer:
Point C's reflection across the x-axis yields coordinates (5, -7). The x-coordinate remains unchanged, while the y-coordinate changes sign, showcasing a fundamental concept in coordinate geometry.
Explanation:
This reflection can be understood as a transformation in which each point on the original figure is flipped over the x-axis to its corresponding point on the reflected figure.
The x-coordinate remains the same because it measures the horizontal distance from the y-axis, which does not change during a reflection across the x-axis. However, the y-coordinate changes sign, as it represents the vertical distance above or below the x-axis.
In summary, to find the coordinates of the reflected point, we change the sign of the y-coordinate of the original point while keeping the x-coordinate unchanged. Thus, the reflected coordinates of point C across the x-axis are (5, -7).
