3x + 2y = 10 ....multiply by -4
12x + 5y = 25
-------------------
-12x - 8y = -40 (result of multiplying by -4)
12x + 5y = 25
------------------add
-3y = - 15
y = -15/-3
y = 5
3x + 2y = 10
3x + 2(5) = 10
3x + 10 = 10
3x = 10 - 10
3x = 0
x = 0
solution is (0,5)
4-25/p
At least that was what I was taught
Answer:
Hello your question has a disjointed equation attached to it and it is also incomplete attached below is the correct and complete question
A teacher believes that the third homework assignment is a key predictor in how well students will do on the midterm. Let x represent the third homework score and y the midterm exam score. A random sample of last terms students were selected and their grades are shown below
answer :
y-intercept = 25.9047
slope = 2.8420
Step-by-step explanation:
Determine the slope for the regression equation and y intercept
The regression equation ( gotten using excel ; attached below is the excel sample on how the equation was gotten )
y = 25.9047 + 2.8420x
from the equation gotten above
y-intercept = 25.9047
slope = 2.8420
I think the smallest sides correspond to the smallest angle measurement. So the smallest side would be UT and then VT and then UV.
Finance charge is a fee that represents the cost of borrowing or credit.
In this equation, it shows the total amount paid through credit subtracted by the cost of vehicle.
let x be the finance charge
x = $4,100 + 36 months ($251.34/month) - <span>$11,578
</span>x = $4,100 + $9,048.24 - <span>$11,578 </span>
x = ($4,100 + $9,048.24) - $11,578
x = $13,148.24 - $11,578
x = $1,570.24.
The finance charge is $1,570.24
