Answer:
7x²sqrt(x)
Step-by-step explanation:
7x^(5/2)
7x^(2½)
7x^(2+½)
7x² × x^½
7x²sqrt(x)
sqrt: square root
Answer:
x=3
Step-by-step explanation:
7x(-3)=18
add 3 to both sides
7x=21
divide by 7 on both sides
x=3
Values of slope = (86-71) / (3pm - 10 am) = 15 / 5 = 3
This value of the slope gives the average rise in temperature per hour.
Answer:
hey, what is your question?
Step-by-step explanation:
Answer:
y = 1.5x + 1
Step-by-step explanation:
→ Choose 2 points
( 2 , 4 ) ( -2 , -2 )
→ Find the gradient
-6 ÷ -4 = 1.5
→ Write into format
y = 1.5x + c
→ Substitute in ( 2 , 4 )
4 = 3 + c
→ Minus 3 from both sides
1 = c
y = 1.5x + 1
