Answer: c
Step-by-step explanation:
substitute
<span>Taliba has $31 to order phone cases online.
Each phone case costs $7, and there is a $4 shipping charge.
How many phone cases, x, can Taliba buy?
^^^ that is the situation that does NOT represent the equation </span>
Answer:
x = 0
y = -2
Step-by-step explanation:
to solve this simultaneous equation we are going to say
let
12x - 3y = 6 ............................ equation 1
2x - y = 2 ................................. equation 2
from equation 2
2x - y = 2 ................................. equation 2
2x - 2 = y
y = 2x - 2 ................................ equation 3
substitute the value of y into equation 1
12x - 3y = 6 ............................ equation 1
12x - 3( 2x -2) = 6
12x -6x + 6 = 6
6x + 6 = 6
6x = 6-6
6x = 0
divide both sides by 6
6x/6 = 0/6
x = 0
put the value of x = 0 into equation 3
y = 2x - 2 ................................ equation 3
y = 2(0) - 2
y = 0 - 2
y = -2
therefore from the solution the value of x is equal to zero(0) and the value of y is equal to -2 respectively.
2√9-5³√-8
√9=3 and 5³=125
2(3)-125 √-8
6-125 √-8
-119 √-8
