Answer:
-113
Step-by-step explanation:
mx - ymx - y
substitute in the values for each variable
(5)(3) - (8)(5)(3) - 8
15 - 120 - 8
Answer:
66
Step-by-step explanation:
One way of solving this is to first add 12 to get the number to 0. Then add another 54 to get to 54 degrees. Then you can add these two numbers together to get 66.
Answer:
5x+3>4x+7
-4x -4x
x+3>7
-3 -3
x>4
so the answer will be the second
Step-by-step explanation:
There are 3 significant figures because there are 3 digits which aren't 0's
Answer:
2. y = 7/2 x -2
3. y = 3/4x-1
Step-by-step explanation:
points (0,-2) (4,12)
slope = (y2-y1)/(x2-x1)
slope = (12--2)/(4-0)
= (12+2)/4
= 14/4 = 7/2
the slope is 7/2 and the y intercept is -2
y = mx+b
y = 7/2 x -2
points (0,-1) (4,2)
slope = (y2-y1)/(x2-x1)
slope = (2--1)/(4-0)
= (2+1)/4
= 3/4
the slope is 3/4 and the y intercept is -1
y = mx+b
y = 3/4x-1
