Natalija [7]

Answer:

x=3 , x=-3

Step-by-step explanation:

$e^{lnx^2} -9= 0$

Add 9 on both sides

$e^{lnx^2}=9$

To remove base 'e' we take ln on both sides

$ln e^{lnx^2}=ln9$

$lnx^2=ln(9)$

Both sides have ln , so we make the terms equal

$x^2=9$

Take square root on both sides

$x=+-3$

x=3 , x=-3

Which equation represents a line that passes through (-2, 4) and has a slope of 1/2?

jok3333 [9.3K]

Answer:

$\large\boxed{y-4=\dfrac{1}{2}(x+2)\text{- point-slope form}}\\\boxed{y=\dfrac{1}{2}x+5\text{- slope-intercept form}}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

We have the slope $m=\dfrac{1}{2}$ and the point $(-2, 4)$ .

Substitute:

$y-4=\dfrac{1}{2}(x-(-2))$

$y-4=\dfrac{1}{2}(x+2)$ - point-slope form

Convert to the slope-intercept form (y = mx + b):

$y-4=\dfrac{1}{2}(x+2)$ <em> use the distributive property</em>

$y-4=\dfrac{1}{2}x+1$ <em>add 4 to both sides</em>

$y=\dfrac{1}{2}x+5$ - slope-intercept form

Use the table to answer the question.

Akimi4 [234]

Step-by-step explanation:

You can choose one of the prices above to find the proportion.

$\frac{2}{4} = \frac{2.30}{y} \\ 2 \times y = 2.30 \times 4 \\ y = 2.30 \times 2 \\ y = 4.60$
