Answer:
y = 7x
y = 5.5x
Sophia
Step-by-step explanation:
Given that:
Aisha runs 1 km in 7 minutes :
Aisha's function :
y = 7x
x = number of kilometers and y is the number of minutes
For Sophia :
Slope = change in y / change in x = (15.5 - 10) / (1 - 0)
Slope = 5.5
Hence, Sophia :
y = 5.5x
Hence, Sophia runs faster as she completes one kilometer in 5.5 minutes. Which is lesser Than Aisha's time. Of 7 minutes.
y = - 
x + 3
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 6, 6 ) and (x₂, y₂ ) = (- 2, 4 )
m = 
= 
= -
y = - x + c is the partial equation
to find c substitute either of the 2 points into the partial equation
using (- 2, 4 ), then
4 = 1 + c ⇒ c = 4 - 1 = 3
y = - x + 3 ← in slope-intercept form
X+y+z = 132
x = 7+z
y = 3z
(7+z)+3z+z = 132
5z = 132-7
z = 125/5
z = 25 <=====
x = 7+z
x = 7 + 25
x = 39 <=====
y = 3z
y = 3 × 25
y = 75 <=====
hope it helps :)
Answer:
The answer to your question is the chocolates are slightly lighter than the weight stated on the label.
Step-by-step explanation:
Data
The label says 0.384 pounds
Actual mass = 0.3798 pounds
Process
To solve this problem the only thing we must do is substrate the actual weight of chocolates to the weight of chocolates stated on the label.
If the result is positive, then the chocolates are lighter
If the result is negative, then the chocolates are heavier
0.384 pounds - 0.3798 pounds = 0.0042
hmu if you need sumin els!
