1. Slope = -7
Y intercept= 8
Answer:
The slope of this is -3
Step-by-step explanation:
slope = change in y/ change in x or rise/run!!!
you move 3 down and 1 to the right. So basically -3/1 which can be simplified to -3!!!!
Answer:
l=25 cm
Step-by-step explanation:
The perimeter of a rectangle
2(l+w)=70 cm
(l+10)=70/2
l=35-10
l=25
Note : you have no question. So I just assume it
Answer: for a the answer is 140° and for b x=25°
Step-by-step explanation:
for a, when you have 2 parallel lines cut by a transversal,the corresponding angles are congruent. and the angle140 is congruent to the corresponding angle as they are vertical angles are congruent.
for b, angle x is congruent to the angle that is supplementary to 155 therefore 180-155=25°
A!! Yes, because adjacent sides aren’t perpendicular
