Answer:
She must make a score of 42 in the final exam to obtain an average of 80.
Step-by-step explanation:
Hi there!
Let x be the score of the final exam, the equation will be as follows (remember that the score of the final counts double):
(82 + 79 + 75 + 2x)/4 = 80
Let´s solve the equation for x multiplying each side of the equation be 4:
82 + 79 +75 + 2x = 320
Substract 82, 79 and 75 to both sides of the equation:
2x = 320 - 82 - 79 -75
2x = 84
x = 84/2
x = 42
She must make a score of 42 in the final exam to obtain an average of 80.
Have a nice day!
Answer:
x=60
Step-by-step explanation:
The angles here are alternate interior angles, this means that they are congruent. Congruent means that they are equal to each other, so to solve just set them equal! (Your variable is x so you're solving for that)
Hope this helps! :)
The require degenerative circle is (x - 5)² + (y - 1)² = 0. Option C is correct.
Given that,
The equation for the degenerative circle is to be determined.
<h3>What is a circle?</h3>
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the circle's center on the coordinate plane and r is the circle's radius.
The degenerative circle is a circle whose radius is zero, from the option,
Option C has the equation of the circle with radius zero.
Thus, the required degenerative circle is (x - 5)² + (y - 1)² = 0.
