1 answer:

7 0

$(2x + 5) \times( x - 2) \\ = 2x(x) + 2x( - 2) + 5(x) + 5( - 2) \\ = 2 {x}^{2} + ( - 4x) + 5x + ( - 10) \\ = 2 {x}^{2} - 4x + 5x - 10 \\ = 2 {x}^{2} + x - 10$
The answer is 2x^2 + x - 10

If y varies directly with x. and y=10 when x=5.6, find the value of y when<br> X=3

Nady [450]

Answer: 5.3571

Step-by-step explanation:

The formula used to calculate direct proportion is: y = kx

We will find the constant of proportionality when y=10 and x=5.6. This will be:

y = kx

10 = 5.6k

k = 10/5.6

k = 1.7857143

The value of y when X=3 will be:

y = kx

y = 1.7857143 × 3

y = 5.3571

Solve and state any extraneous solutions

Mice21 [21]

$\frac{3x}{x - 1} + 2 = \frac{3}{x - 1}$

$\frac{3x}{x - 1} + \frac{2(x - 1) }{ x - 1} = \frac{3}{x - 1}$

$\frac{3x}{x - 1} + \frac{2x - 2}{ x - 1} = \frac{3}{x - 1}$

$\frac{3x + 2x - 2}{ x - 1} = \frac{3}{x - 1}$

$3x + 2x - 2 = 3$

$5x - 2 = 3$

$5x = 3 + 2$

$5x = 5$

$x = \frac{5}{5}$

$x = 1$
