For every van there are 6 students 6x,(6 students,x is the number of vans)
Use desmos graphing calculator, for visuals. It's easy to use as well.
A is 0 (zero)
(1x1 + 2x1 - 3)
B) D ( lies on 1 on our x-axis)
C) This tells you to draw a line at zero on the y-axis, a horizontal line BTW & read off the x values, where the line touches the pink graph/diagram.
y=x^2+2x-3 is the similar to x^2+2x-3=0 because the letter y now represents zero. So, that's why we draw the line y=0 (a horizontal line at zero). Then, use it to find the x values.
Thus, x = - 3 & x = 1
Hope this helps!
Answer:
so all x's have to be added together.
8x+5x+10x+7x=30x
-2+3=1
1dividedby30=30
x=30
hope this helps
ASA - If two pairs of angles of two triangles are equal in measurement, and
the included sides are equal in length, then the triangles are
congruent.
