Solving special systems {y=1/2x+4 {-1/2x+y=-5

Mathematics
1 answer:
ryzh [129]3 years ago

Answer:

no solution

Step-by-step explanation:

Given the 2 equations

y = \frac{1}{2} x + 4 → (1)

- \frac{1}{2} x + y = - 5 → (2)

Substitute y = \frac{1}{2} x + 4 into (2)

- \frac{1}{2} x + \frac{1}{2} x + 4 = - 5 , that is

4 = - 5 ← not possible

This indicates the system has no solution

Answer:

x = 67°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles from 180 for x , that is

x = 180° - (38 + 75)° = 180° - 113° = 67°

Choose the equation of the line that contains the points (1,-1) and (2,2)
natka813 [3]
(1,-1)(2,2)
slope = (2 - (-1) / (2 - 1) = 3/1 = 3

y = mx + b
slope(m) = 3
use either of ur points...(2,2)...x = 2 and y = 2
now we sub and find b, the y int
2 = 3(2) + b
2 = 6 + b
2 - 6 = b
-4 = b

so ur equation is : y = 3x - 4

4 less than a number n is - 15 as a equation
Nikitich [7]

Answer:

I believe the equation would be n - 2 = -15.

Step-by-step explanation:

"4 less than a number (n)" is subtraction. You can write it as "n minus 4". "is -15" means this is the difference. This can also be written as "equals -15".

n - 4 = -15
