Answer:

Given below.

Step-by-step explanation:

using the formula :

y = mx + c ....where m is the slope and c is the y intercept

(a) if slope 1/3; y intercept = -1

y = x/3 - 1

(b) if slope -2/5; y intercept = 0

y = -2x/5 + 0

y = -2x/5

(c) if slope= -1; y intercept= 4

y = -1x + 4

y = -x + 4

\qquad \qquad\huge \underline{\boxed{\sf Answer}}

Here's the solution ~

Slope intercept form of an equation is :

\qquad \sf  \dashrightarrow \: y = mx + c

where,

  • m = slope

  • c = y - intercept

Now, let's find the required equations ~

<h3>A.) Slope = 1/3 and y intercept = -1 </h3>

\qquad \sf  \dashrightarrow \: y =  \dfrac{1}{3} x - 1

<h3>B.) Slope = -2/5 and y intercept = 0</h3>

\qquad \sf  \dashrightarrow \: y =   - \dfrac{2}{5} x

<h3>C.) Slope = - 1 and y intercept = 4 </h3>

\qquad \sf  \dashrightarrow \: y =  - x + 4

Exit Ticket: At noon, a tank has a water depth of 9 in. After 3 hours, the depth was 8 inches. At 6pm, the depth was 7 inches. W
OLEGan [10]

Answer:

Step-by-step explanation:

The  straight line equation is:

y = m*x  + b     Where m is the slope of the line and b the intercept with   y-axis, in our case y is the depth of the tank and x (time in lapsus of 3 hours).

The slope m  =  ( y₂ -  y₁ ) / (x₂ - x₁)

We have point  A ( 3 , 8 )  and point  B ( 6 , 7 )

m  = ( 6 - 3 ) / (7 - 8 )  m = -3

We see that  each 3 hours time-depth decreases  1 in.

Then   to find the depth at the beginning of x-axis

At  noon     12   tank was  9 inches, three hours before at 9 in the morning the depth was 10 inches and:

9  in the morning   10

6  in the morning   11

3  in the midnight   12

12 in the night         13

Then 13 is the intercept with y-axis

then the equation is:

h = - 3*x + 13

Note x is time in lapsus  of 3 hours

Can anyone help me with this problem by factoring and list the steps please
jok3333 [9.3K]

Answer:

m=2, m=0

-ˋˏ✄┈┈┈┈┈┈┈┈┈┈┈┈┈

20m^2-40m=0

<u>Use quadratic formula:-</u>

᠃ ⚘᠂ ⚘ ˚ ⚘ ᠂ ⚘ ᠃

m_1,_2=\frac{-(-40) -+\sqrt{x} (-40)^2-4*20*0}{2*20}

\sqrt{(-40)^2-4*20*0}=40

m_1,_2=\frac{-(-40)-,+40}{2*20}

m_1=\frac{-(-40)+40}{2*20},m_1=\frac{-(-40)-40}{2*20}

m=\frac{-(-40)+40}{2*20}:2

m=\frac{-(-40)-40}{2*20}:0

m=2, m=0
