Explain how you can determine that the following system has one unique solution – without actually solving the system.

Mathematics
1 answer:
MakcuM [25]4 years ago
7 0

Answer:

Step-by-step explanation:

Well, first you'd have to get the equations in slope-intercept form in order to make it easier for you to see it in the bigger picture. 2x+y=4 would be y= 2x-4, and the other equation would be y= x-3. If you were to solve it, there would be one solution since the y's cancel out. If you graphed it, there would be a point of intersection, unlike when the lines are parallel if there's 0 solutions or only one line's there if there's infinitely many solutions.

Divide 42 in the ratio of 4:3
lubasha [3.4K]
42 in a 4x to 3x ratio

4x + 3x = 42
7x = 42
x = 6

43 can be put in a 4(6) to 3(6) ratio

which is a 24 to 18 ratio, also written as 24:18

Note:
<span>a(b) = ab = a x b = a times b</span>

What is the slope of the equation y = 2 x - 1? 3 x​
N76 [4]

Answer:

2

Step-by-step explanation:

If the equation is in the form y = mx + b, then m is the slope and b is the y-intercept (For example - in the equation y = 3x + 2 the slope is 3 and the y-intercept is 2)

In this case, the number next to x is 2, so that's the slope.
