Answer:
3)B y intercept is -5 which is what the -5 in the equation stands for, the slope is -2 which means 2 up one left (left since slope is negative)
4)C y intercept of -2, slope is 3/4 rise over run which means we go up 3 and right 4 (right sense slope is positive)
5)A y intercept of 1, slope of 7 which means up 7 over 1
A. Median. That is simply what it is called
Answer:
B. because the first one has 3 sides second has 4 third has 5 and B. has 6
the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0
13x^2-16x = x^2 -x
we need to get in it the standard form
subtract x^2 from each side
12x^2 -16x = -x
add x to each side
12x^2 -15x = 0
12x^2 -15x -0 =0
a=12 b=-15 c=0
b^2 -4ac
the discriminant = b^2
b^2 = (-15)2 = 225
23 m, 17 m, 14 m
Cuz the length of a side must be bigger than the difference of the other two
