Answer:
(-1.85, -0.15)
Step-by-step explanation:

Here,
x1 = -5.1
x2 = 1.4
y1 = -2
y2 = 1.7
Now substituting the values we have in the equation, we get:-


The coordinates of the midpoint would be = (-1.85, -0.15)
Answer:
this equation cannot be written in slope-intercept form
Step-by-step explanation:
The given equation is equivalent to ...
2x +9 = 0 . . . . . subtract 1x
x + 4.5 = 0 . . . . divide by 2
x = -4.5 . . . . . . . the equation of a vertical line.
It has no y-intercept and its slope is undefined.
Answer:
6 cm,12 cm,8 cm
Step-by-step explanation:
add the perimeter of the first triangle to get 65
then divide 65 by 26 to get 2.5
then divide all the side lengths by 2.5
15/2.5=6
20/2.5=8
30/2.5=12
False because the sentence can be completed well without adjective too
