Y=x²-4x+6<br> y=x+2<br><br><br> Please help

Ira Lisetskai [31]

Answer:

(1, 3), (2, 4).

Step-by-step explanation:

y= x² - 4x + 6

y = x + 2

Substitute for y in the first equation:

x + 2 = x²- 4x + 6

x^2 - 5x + 4 = 0

(x - 1)(x - 4) = 0

x = 1, 4

When x = 1 , y = 1 + 2 = 3.

When x = 4, y = 4 + 2 = 6.

Sally has six more 34 cent stamps than 52 cent stamps. If her stamps amount to 11.50 how many of each stamp does she have?

Yuliya22 [10]

Let x be the number of 52 cent stamps that Sally has and let y be the number of 34 cent stamps that she has.

Then,

52x + 34y = 1150 --- (1)

Also, she has six more 34 cent stamps than 52 cent stamps.

Therefore, y = x + 6

(1) becomes

52x + 34(x + 6) = 1150

52x + 34x + 204 = 1150

86x + 204 = 1150

86x = 1150 - 204

86x = 946

x = 11

and y = 11 + 6 = 17

Hence, Sally has eleven 52 cent stamps and seventeen 34 cent stamps.

liraira [26]

Answer:

x=1.4

Step-by-step explanation:

Write the equation

$\frac{5.6}{x} =4$

Multiply both sides by x

$5.6=4x$

Divide both sides by 4

$1.4=x$
