3x + 4y = 17.....multiply by 4
-4x - 3y = -18 ...multiply by 3
------------------
12x + 16y = 68 (result of multiplying by 4)
-12x - 9y = - 54 (result of multiplying by 3)
------------------add
7y = 14
y = 14/7
y = 2
3x + 4y = 17
3x + 4(2) = 17
3x + 8 = 17
3x = 17 - 8
3x = 9
x = 9/3
x = 3
ur solution is (3,2)
Answer:
see below
Step-by-step explanation:
|4x−4(x+1)|=4
First simplify in the absolute value
Distribute
|4x−4x-4|=4
|-4|=4
Taking the absolute value
4 =4
This is always true
X is all real numbers
Pick any value for x and it will be a true statement
x=0
|4*0−4(*0+1)|=4
|-4|=4
Let x = 5
|4*5−4(5+1)|=4
|20−24|=4
|−4|=4
The answer is alternate interior angles theorem and substitution property of equality.
Answer:
-3.8
Step-by-step explanation:
u = 3.8
u × -1 = 3.8 × -1
-u = -3.8
