Answer:
-1
Step-by-step explanation:
Pick two points on the line
(0,1) and ( 2,-1)
Using the slope formula
m = (y2-y1)/(x2-x1)
= ( -1 -1)/(2-0)
= -2/2
= -1
the answer is D the last one,
the reason is just that any negative number is automatically smaller than a positive number. so -2.8 is smaller than even the smallest decimal possible as long as that decimal is positive. 1.4 is actually about 3 time more that -2.8
(both are still freezing cold)
Answer:
y=9
Step-by-step explanation:
Isolate the variable by dividing each side by factors that dont contain the variables
move variable to left side and change its sign
42-7y+3y=6 collect like terms
-7y +3y=6-42
-4y=6-42
-4y=-36 divide both sides of the equation by -4
y=9
hope that helps :)
In a quadrilateral the interior angles add up to 360 degrees so if you subtract 90, 53, and 74 from 360 you get the fourth angle
360-90-53-74 = 143
D. 143
