On a math test, Larissa was asked to find the points where the equations y = x2+ x – 4 & y = -2x + 6 intersect.

Larissa’s solution is shown below.

Larissa checks her answer and realizes she has made a mistake. On which line did Larissa make her mistake?

Explain Larissa's mistake using 1-3 complete sentences.

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: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
