Billy graphed the system of linear equations to find an approximate solution.

y = x +
y = x – 3

which points are possible approximations for this system? check all that apply.

(1.9, 2.5)
(2.2, –1.4)
(2.2, –1.35)
(1.9, 2,2)
(1.9, 1.5)

(2.2, –1.4)  and (2.2, –1.35)

Step-by-step explanation:

The solution to this system of equations would be the point of intersection of the lines.  This point is a little past 2 on the x-axis and a little below 1 on the y-axis.  The only two points in our choices that fit these criteria are (2.2, –1.4)  and (2.2, –1.35).

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
