162=470m+b and 183=540m+b.
183-162=(540-470)m, 21=70m so m=0.30.
162=470×0.30+b=141+b, b=162-141=21
Therefore y=0.30m+21.
Answer:
Step-by-step explanation:
4. 2x-5>1 = 2x>6 x>3 ( since there is a line under the > you will make the dot filled in/ closed at the number 3 and point it towards the positives or higher numbers than three since x is bigger
5. 2x+5>1 = 2x>-4 x>-2 Make this a closed/ filled in dot too at -2 because of the line underneath and point the arrow to all numbers bigger than -2 since x is bigger
6. 2x-5<1 = 2x<6 x<3 This dot will just be a circle NOT FILLED IN at 3 and point the arrow to all values lower than 3
Answer:
1st,2nd, and 4th
Step-by-step explanation:
1)
2x + 14 = 28➡ x = 7
2)
60 = 4x + 32 ➡ x = 7
3)
2x - 6 -12 = -2x - 20 ➡ 4x = -2x = -1/2
4)
3x - 15 = 1 + 5x - 30 ➡14 = 2x ➡ x = 7
Answer:
$8
Step-by-step explanation:
This system of equations relates the ticket price, in dollars, for seats in the silver (x) and gold (y) sections at a rock concert. x + 2y = 82 3x + y = 96 By how much does the price of a ticket for the gold section exceed the price for a ticket for the silver section?
Two equations are presented in this question
x + 2y = 82 equation 1
3x + y = 96 equation 2
Multiply equation 1 by 3
3x + 6y = 246 equation 3
subtract equation 2 from 3
5y = 150
y = 30
Substitute for y in equation 1
x + 2(30) = 82
x = 82 - 60
x = 22
difference in price = 30 - 22 = $8
x =
