Answer: Number one would be 3x+2y+-14 and x+y=-4, second one is x=-3, y=7
Step-by-step explanation:
The first one is solved by inputting the x and y in each one and finding which one comes out true, the second on is solved by substitution. to find x you would subtract x in the first equation and make it y=4-x then input that equation in the y in the second equation.
Answer:
$63
Step-by-step explanation:
In order to solve this problem, we need to find the unit price, which is the price per 1 ticket in this case. To find this, we need to divide $45 by 5 because each ticket is the same amount: $45 / 5 = $9. So each ticket is $9.
Now, we need to find how much 7 tickets would cost. To do this, multiply the $9 / ticket by 7 tickets: $9 * 7 = $63.
This, 7 tickets would cost $63.
Hope this helps! God Bless u!!!
Answer:
b. x= -6 or x=2
Step-by-step explanation:
|2x+ 4| = 8
The absolute value equation has 2 solutions, one positive and one negative
2x+4 = 8 2x+4 = -8
Subtract 4 from each side
2x+4-4 = 8-4 2x+4-4 = -8-4
2x = 4 2x = -12
2x/2 =4/2 2x/2 = -12/2
x =2 x = -6
Answer:
Missing side is 9 cm
Step-by-step explanation:
a^2 + b^2 = c^3
(12)^2 + b^2 = (15)^2
144 + b^2 = 225
b^2 = 81
= 
b = 9 cm
