5x + y = 15
y = -5x + 15
Substituting y= -5x+15 from first equation into second equation:
3x + 2y = 16
3x + 2·(-5x + 15) = 16
3x - 10x + 30 = 16
-7x + 30 = 16
7x = 30 - 16 = 14
x = 2
Substituting x=2 into the first equation:
5x + y = 15
5(2) + y = 15
10 + y = 15
y = 15 - 10
y = 5
So your final answers are x=2 and y=5.
A. The y-intercept is y = −0.05 x + 16 and the x-intercept is x = −20y + 320
B. The x-intercept represents the number of miles the car has traveled.
C. The y-intercept represents the number of gas in gallons.
Answer:
28
Step-by-step explanation:
x equals 1
y equals 11
you would plug the numbers in
(1)6 plus (11)2 which if you multiply them
6 plus 22 would give you 28
Hey there
1 km = 1000 meters
So 5 km will equal 5000 meters
.1 will equal 100 meters
5.1 km = 5100 meters
<span>100,000 centimeters = 1 kilometer
</span>5.1 km = 510000 centimeters
Hope this helps
Answer:
The formula: e7 = (b7*d7)+(c7*d7*1.5)
Step-by-step explanation:
Given:
Hours worked = b7
Hourly rate = d7
Overtime hours = c7
Salary calculation = e7
Salary = Hours worked*hourly rate + (overtime*hourly rate)*1.5
Formula
e7 = (b7*d7)+(c7*d7*1.5)
The formula e7 = (b7*d7)+(c7*d7*1.5)
Hope this will helpful to you.
Thank you.
