20 POINTS HELP ME PLEASE How many solutions does the system have

Mathematics
1 answer:
finlep [7]3 years ago
3 0

Answer:

Two

Step-by-step explanation:

x² + 4 = 4x + 1

x² - 4x + 3 = 0

x² - 3x - x + 3 = 0

x(x - 3) - (x - 3) = 0

(x - 3)(x - 1) = 0

x = 1, 3

y = 4(1) + 1 = 5

y = 4(3) + 1 = 13

Two solutions: (1,5) (3,13)

Find the value of x in the figure given that SU = 133.<br><br> A) 7<br> B) 9<br> C) 11<br> D) 8
Alekssandra [29.7K]

Answer:

The answer is 9 (B)

Step-by-step explanation:

I got 9 because you have to plug in answer (7, 9, 11, 8) in each equation than add them both together. I first plugged in 7 for x in the equation 9x-5. I got 58. I plugged in 7 for x in the equation 5x+12 and got 47. When I added both the answers together I got 105. The answer was to low because SU has to be 133. I plugged in 9 for x in both equations then added them both and got 133 for SU. I hope this helps.

Answer:

Given :

→x-y=12

→xy= 3²

=9

Equation formed:

{(x - y)}^{2}  =  {x}^{2}  +  {y}^{2}  - 2xy

Step by step explanation:

{(12)}^{2}  =  {x}^{2}  +  {y}^{2}  - 2 \times 9 \\  144   + 18 =  {x}^{2}  +  {y}^{2}  \\  = 162
