Answer:
A) 12 feet or d) 10 feet..
8am : -14F
noon : -14+10 = -4F
increase between noon and 4 is 2*10 =20
4 pm: -4F + 20 = 16F
temperature at 4 pm is 16F
Answer: y = 2x + 4
Step-by-step explanation:
y = mx + b
(1,6) and (2,8)
Finding Slope:
(8 - 6) / (2 - 1)
=> 2/ 1 or 2
y = 2x + b
Finding "B":
y = 2x + b
=> 6 = 2(1) + b
=> 6 = 2 + b
=> b = 4
so y = 2x + 4
Answer:
Step-by-step explanation:
y=-6x
slope=-6
slope of line ⊥ to given line=1/6
eq. of reqd. line is
y+2=-1/6 (x+1)
6y+12=-(x+1)
or
6y+12=-x-1
6y+x=-1-12
or 6y+x=-13
Answer:
x = 13
y = 9
Step-by-step explanation:
Since this is a square all the side lengths would be equal to each other
4x - 22 = 2x + 4
4x - 2x = 4 + 22
2x = 26 divide both sides by 2
x = 13
5y - 15 = 3x + 3
5y - 3x = 3 + 15
2y = 18 divide both sides by 2
y = 9
