Answer:

no solutions

Step-by-step explanation:

We can solve this system using elimination. In this case, we can eliminate x and y by subtracting the two equations:

0=15-12

0=3

This is not true, meaning the system does NOT have any solutions.

The equation for a line is:

y=mx+b

m: slope

b: y-intercept

Here we can see the two lines have the same slope, meaning they are parallel. If they are parallel, they do not intersect which means there is no solution.

How do i do this pls help me

Delvig [45]

Answer:

$y = \frac{1}{7} x + 7$

Step-by-step explanation:

x-7y = -49

i) move x to the right-hand side and change its sign

-7y = -49-x

ii) change the signs on both sides of the equation

7y = 49+x

iii) divide both sides of the equation by 7

$\frac{7y}{7} = \frac{49}{7} + \frac{x}{7}$

$y = 7 + \frac{1}{7} x$

iv) use the commutative property to reorder the terms

* commutative property: a+b = b+a

$y = \frac{1}{7} x + 7$

How to figure out 5 - 0.53

sveta [45]

the answer would be 4.47

because every whole number is made out of 100 small parts.

So that would be like 400-53 which is 447 and then add the decimal point. That would make it 4.47

What's the difference between using f(2) and f(x)=2?

BabaBlast [244]

F(2) means that you are plugging in 2 for x, while f(x)=2 means that the equation equals 2 (y=2) at a certain x value.
