Answer:
-23 degree
Step-by-step explanation:
=>-14-5-3-1
=>-23
Answer:
-23°
Step-by-step explanation:
= -14 - (5+3+1)
= -14 - 9
= -23°

Answer:
y=2x+60
Step-by-step explanation:
Since the starting temperature is 60 degrees, that will be the y intercept. the temperature rises by 2 degrees every one hour, so the slope is 2. y=2x+60.
Answer:
Step-by-step explanation:
let s be speed and t be time taken
s*t=649
(s+8)(t-4)=649
st-4s+8t-32=649
-4s+8t-32=0
4s=8t-32
s=2t-8
2t=s+8
t=4+s/2
Answer:
x = 3
Step-by-step explanation:
-9 + 3(-5x + 7) = -33
-9 - 15x + 21 = -33
- 15x + 12 = -33
-12 = -12
-15x = -45
/-15 /-15
x = 3
Well its not very precise, but it's 3.46410161514
Substitute the given values (slope = -0.32 and b = 4.75) into y = mx + b:
y = -0.32x + 4.75 is the equation of this line in slope-intercept form.
