Q: Reflect B (2,7) over the y-axis
Answer:
(-2,7)
Hope this helps! Feel free to comment on this reply if you have any questions. :)
<span>Apprentice B earns $120 because Apprentice A's wage is $4/hour (160 divided by 40), and the question states that they are paid at the same scale. Therefore 4 x 30 = $120.</span>
Volume=4/3 pi r^3. so 4/3 pi r^3 = 500/3 pi. Therefore, divide by pi, and multiply by 3, you get 4r^3=500. Divide by 4 to get r^3=125, and cube root to result in 25. r=25.
The correct answer is y = 11
because:
2y + 7 = 3y − 4
−y + 7 =−4
Subtract 7 from both sides.
−y + 7 − 7 = − 4 − 7
−y = −11
Divide both sides by -1.
y = 11
