Answer:
No
Step-by-step explanation:
(3, 10)
3 = x
10 = y
Substitute into equation
10 = 4(3)
10 = 12
No it isn't a solution as y doesn't = x
This is looking for the sum of 2 numbers: n and "5 larger than n"
"5 larger than n" is equivalent to n + 5
Now we have n + n + 5
The problem says this is 41, so
n + n + 5 = 41
Answer:
135 degrees
Step-by-step explanation:
A triangle is 180 degrees and because the triangle has a 90 degree and an 45, it would add up to 135 and 180 minus 135 is 45.
X | -0.6x - 0.6y = -0.6 | 0.5x - 0.3y = -2.7 |
| y | y
-4 | 5 | 2 1/3
-3 | 4 | 4
From the table, solution is (-3, 4)
12x + 3y = 12 => 3(4x + y) = 12. . . (1)
y = -4x + 5 => 4x + y = 5 . . . (2)
Since, the left hand side of (2) is a factor of the left hand side of (1), the system is dependent.
