Check the consistency of 2x-3y=7 and x-2y+1=0

Mathematics
1 answer:
Furkat [3]3 years ago
3 0

Answer:

x = 17, y = 9

or as an ordered pair, (17, 9).

The equations are consistent.

Step-by-step explanation:

2x - 3y = 7

x - 2y  = -1        Multiply this equation by -2:

-2x + 4y = 2     Add this to the first equation:

y = 9.

Plug y = 9 into the second equation:

x - 2*9 = -1

x = -1 + 18 = 17.

olya-2409 [2.1K]

Answer:

B. (-7 +/-√33) / 4

Step-by-step explanation:

2x2 + 7x + 2 = 0

x =  [-7 +/-  √(7^2 - 4*2*2)] / 2*2

x = -7/4 +/- √(33) / 4

=  (-7 +/-√33) / 4

There are two spinners. Each spinner has 10 equal sectors labeled with the numbers 1 through 10.
murzikaleks [220]

Answer:

There are 4 prime numbers from 1 to 10: 2, 3, 5, and 7. This means that there are 4 ways to choose the first outcome. There are 5 composite numbers from 1 to 10: 4, 6, 8, 9, and 10 (1 is just 1). So, you just multiply the two numbers together because each depends on each: 4 * 5 = 20 outcomes.

Which point does the line with equation y+4=3(x-7) pass through?
gregori [183]
<span>y+4=3(x-7)
y + 4 = 3x - 21
y = 3x - 21 -4
y = 3x - 25

when x = 7
y = 3(7) - 25
y = -4
Therefore (7, -4) pass through this equation </span>
