Answer:

3. $\displaystyle x-intercept: [-4\frac{1}{2}, 0] \\ y-intercept: [0, -9] \\ Slope-Intercept\:Form: y = -2x - 9$

2. $\displaystyle x-intercept: [5, 0] \\ y-intercept: [0, 1] \\ Slope-Intercept\:Form: y = -\frac{1}{5}x + 1$

1. $\displaystyle x-intercept: [4, 0] \\ y-intercept: [0, -3] \\ Slope-Intercept\:Form: y = \frac{3}{4}x - 3$

Step-by-step explanation:

−2x - y = 9

x-intercept → Plug in 0 for y to get −4½ for x

y-intercept → Plug in 0 for x to get −9 for y

−2x - y = 9

+ 2x + 2x

_________

$\displaystyle \frac{-y}{-1} = \frac{2x + 9}{-1}$

$\displaystyle y = -2x - 9 →$ Slope-Intercept Form

_______________________________________________

x + 5y = 5

x-intercept → Plug in 0 for y to get 5 for x

y-intercept → Plug in 0 for x to get 1 for y

x + 5y = 5

- x - x

_________

$\displaystyle \frac{5y}{5} = \frac{-x + 5}{5}$

$\displaystyle y = -\frac{1}{5}x + 1 →$ Slope-Intercept Form

_______________________________________________

3x - 4y = 12

x-intercept → Plug in 0 for y to get 4 for x

y-intercept → Plug in 0 for x to get −3 for y

3x - 4y = 12

- 3x - 3x

_________

$\displaystyle \frac{-4y}{-4} = \frac{-3x + 12}{-4}$

$\displaystyle y = \frac{3}{4}x - 3 →$ Slope-Intercept Form

$((( {64}^{ \frac{1}{2}})^{ \frac{1}{8}} )^{2} = \\$

$( {64}^{ \frac{1}{16} })^{2} = \\$

$(64)^{ \frac{1}{8}} = \\$

$( {2}^{6} )^{ \frac{1}{8} } = \\$

${2}^{ \frac{3}{4} } = \\$

$\sqrt[4]{2^{3} } = \\$

$\sqrt[4]{8}$

What number is composed of 4 thousands +7 hundreds + 16 tens + 9 ones

Yanka [14]

4 thousands = 4000
7 hundreds = 700
16 tens = 160
9 ones = 9

Then you add them all together:
4000 + 700 + 160 + 9

Your answer is 4869.

PilotLPTM [1.2K]

Answer:

12i because we have the square root of -144, so we have 144 times -1, and we square root 144 to get 12, and the square root of -1 is i, so we have 12i.
