Answer:
Her mistake is on line 2, setting the equations equal to each other.
Step-by-step explanation:
It appears that she misunderstood the requirements of question: find the intersections of the graphs of the two equations. The first one is a quadratic equation, (mentally picture that as a parabola). The second equation is linear. (Mentally picture that as a straight line with a slope of -2) They should have 2 points of intersection. When she combined them, she created a new quadratic equation and solved to "find the zeroes" where the parabola intersects the x-axis.
Answer:
Step-by-step explanation:
or, 3(2y-4) = 1(y+7)
or, 6y-12 = y +7
or, 6y-y = 7+12
or, 5y = 19
or, y = 19/5
Answer:
from least to the greatest
Answer:
$1200
Step-by-step explanation:
First we need to find 25% of 5,000, which is 5,000*.25=1250
Then we need to reduce 50 from 1250 which is 1250-50=1200.
Hope this helps!
