Answer: C
Steps: 4x + y = -4, x + y = 2
Isolate the x for (x + y = 2): x = 2 - y
Plug the value of x into the other equation: 4(2 - y) + y = -4
Simplify: -4y + 8 + y = -4
Combine like variables (letters): -4y + y = -3y
So -3y + 8 = -4
Subtract eight from both sides: -3y + 8 - 8 = -4 - 8
-3y = -12
Divide both sides by negative three: -3y ÷ -3 = -12 ÷ -3
Simplify: y = 4
Plug the value of y into one of the original equations (I'll use x + y = 2):
So x + 4 = 2
Isolate the x variable: x = -2
Answer:0.03
Step-by-step explanation:
you divide 475 into 16.625 which = 0.03
Answer:
Any graph with the same slope but with different y intercepts is parallel to that. For example in y = mx + b form the equation will be
y = 4x - 15
So, some equations that will be parallel
y = 4x
y = 4x - 16
y = 4x +3
Hoped this helped ya :)
Answer:
The new length of the tear is 2.3 * 10^-2 inch
Step-by-step explanation:
Here, we are concerned with knowing the new length of the tear.
Originally, the length of the tear is 2.3 * 10^-4 inch.
But this tear became 100 times longer. The new length of the tear will be the old length * 100
Mathematically, that would be 2.3 * 10^-4 inch * 100
= 2.3 * 10^-4 * 10^2
= 2.3 * 10^(-4 + 2)
= 2.3 * 10^-2 inch
