What is the slope and the y-intercept of -1.7x-1.9y=5.8

Julli [10]

Answer:

The slope is -0.89 and the y-intercept is (0, -3.05).

Step-by-step explanation:

To find the slope and y-intercept, convert the equation to y=mx+b where m=slope and b=y-intercept.

Convert the equation by rearranging the terms using inverse operations.

-1.7x - 1.9y = 5.8 Add 1.7x to both sides.

+1.7x +1.7x

------------------------------------

-1.9y = 5.8 + 1.7x Divide both sides by -1.9.

y= - 0.89 x - 3.05

This is now in y=mx+b and m=-0.89 and b=-3.05.

The slope is -0.89 and the y-intercept is (0, -3.05).

Divide.

inysia [295]

Answer:

$\frac{406}{27}$ or $15\frac{1}{27}$

Step-by-step explanation:

we have

$\frac{1,218}{81}$

decompose the numbers in prime factors

$1,218=(2)(3)(7)(29)$

$81=3^4$

substitute

$\frac{1,218}{81}=\frac{(2)(3)(7)(29)}{3^4}$

simplify

$\frac{(2)(7)(29)}{3^3}=\frac{406}{27}$

Convert to mixed number

$\frac{406}{27}=\frac{405}{27}+\frac{1}{27}=15\frac{1}{27}$

The linear equation has 9(x+3)=3(3x+6)+9

aleksandrvk [35]

Answer:

<h2>∞ (Infinitely many solutions)</h2>

Step-by-step explanation:

9(x+3)=3(3x+6)+9

Apply distributive property:

$9(x+3)=3(3x+6)+9\\ 9x+27=9x+18+9$

$9x+27=9x+27$

<em>The equations are the same, which means that all values of x would make the linear equation ture.</em>
