Equation with a slope of -4 and goes through the point (-1,1)

spin [16.1K]

<h2>SOLVING</h2>

$\Large\maltese\underline{\textsf{A. What is Asked}}$

What's the equation with a slope of -4 that goes through (-1,1)? find it

$\Large\maltese\underline{\textsf{B. This problem has been solved!}}$

The equation used, here is $\bf{y-y1=m(x-x1)}$ .

$\bf{y-1=-4(x-(-1)}$ | simplify after putting in the information given

$\bf{y-1=-4(x+1)}$

$\rule{300}{1.7}$

$\bf{Result:}$

$\bf{=y-1=-4(x+1)}$

$\boxed{\bf{aesthetic\not101}}$

Simplify.<br> (-8V2)(+1/2V32)

erastovalidia [21]

Hello!!

$\rule{300}{5}$

$\huge\blue{{\fbox{\tt{ANSWER:-\:}}}}$

$-32$

$\huge\red{{\underline{\overline{\textbf{MY\:EXPLANATION~!}}}}}$

Apply rule: $(-a) = -a$

$(-8\sqrt{2}) = - 8\sqrt{2}$

$= -8\sqrt{2}~\frac{1}{2}\sqrt{32}$

$\sqrt{2}~\sqrt{32} =\sqrt{64}$

$= -8\sqrt{64}~\frac{1}2}$

$\sqrt{64} = 8$

$= -8$ · $8$ · $\frac{1}{2}$

Multiply the numbers: $-~8$ · $8= -64$

$=-64$ · $\frac{1}{2} = -32$

$= -32$

Hope It Helps. . .

Consider the following.3x + 3y = 8(a) Find y' by implicit differentiation.(b) Solve the equation explicitly for y and differenti

ludmilkaskok [199]

Answer:

a.y'=-1

b.y'=-1

c.Yes

Step-by-step explanation:

We are given that consider a function

$3x+3y=8$

Implicit function: That function is a relation in which dependent variable can not be expressed in terms of independent variable

Explicit function: It is that function in which dependent variable can be expressed in terms of independent variable.

a. $3x+3y=8$

Differentiate w.r.t x then we get

$3+3\frac{dy}{dx}=0$

$3\frac{dy}{dx}=-3$

$\frac{dy}[dx}=\frac{-3}{3}=-1$

$\frac{dy}{dx}=y'=-1$

b. $3x+3y=8$

$3y=8-3x$

$y=\frac{8-3x}{3}$

Differentiate w.r.t x then we get

$\frac{dy}{dx}=\frac{-3}{3}=-1$

$\frac{dy}{dx}=y'=-1$

When we substituting the value of y obtained from part b into a solution of part a then we get

$y'=-1$

Hence, solutions are consistent.

Tammy purchased a prepaid phone card for $15. Long distance calls cost 18 cents a minute using this card. Tammy used her card on

Mars2501 [29]

Answer:

46 minutes

Step-by-step explanation:

Sorry about not answering your question sooner, but here is your answer:

In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left ver after the call:

15 - 6.72 = 8.28

Then, we divide this number by 0.18:

8.28 / 0.18 = 46

So, Tammy's call lasted 46 minutes

Hope this helps :)
