Rewrite the equation in slope intercept form 7x + 9y = 9
shtirl [24]

Answer:

y = -7/9 x +1

Step-by-step explanation:

7x + 9y = 9

The slope intercept form is y = mx+b  where m is the slope and b is the y intercept

Subtract 7x from each side

7x -7x+ 9y =-7x+ 9

9y = -7x+9

Divide each side by 9

9y/9 = -7/9 x +9/9

y = -7/9 x +1

The  slope is -7/9 and the y intercept is 1

Estimate the limit. <br> Picture below
vova2212 [387]

Answer:

Hence, the limit of the expression:\lim_{x \to 1} \dfrac{\dfrac{1}{x+2}-\dfrac{1}{3}}{x-1} is:

\dfrac{-1}{9}

Step-by-step explanation:

We are asked to estimate the limit of the expression:

\lim_{x \to 1} \dfrac{\dfrac{1}{x+2}-\dfrac{1}{3}}{x-1}

We will simplify the expression by first taking the l.c.m of the terms in the numerator to obtain the expression as:

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

\lim_{x \to 1} \dfrac{1-x}{3(x+2)(x-1)}\\\\= \lim_{x \to 1} \dfrac{-(x-1)}{3(x+2)(x-1)}\\\\\\= \lim_{x \to 1} \dfrac{-1}{3(x+2)}

since the same term in the numerator and denominator are cancelled out.

Now the limit of the function exist as the denominator is not equal to zero when x→1.

Hence,

\lim_{x \to 1} \dfrac{-1}{3(x+2)}\\\\=\dfrac{-1}{3(1+2)}\\\\=\dfrac{-1}{3\times 3}\\\\=\dfrac{-1}{9}

Hence, the limit of the expression:\lim_{x \to 1} \dfrac{\dfrac{1}{x+2}-\dfrac{1}{3}}{x-1} is:

\dfrac{-1}{9}

Please show how you got the answer.​
Lera25 [3.4K]

Answer:

cosA = 8/17

Step-by-step explanation:

cos =  adjacent/hypotenuse

The number that is adjacent to angle A is 24 and the hypotenuse is 51

Plug the numbers into the cosine equation, which would look like:

Cos A = 24/51

You can simplify the fraction by dividing it by 3

So Cos A = 8/17 or 0.89130173...
