Answer:

\frac{0.2x + 1}{7}  = 0.4 \\ 0.2x + 1 =0.4 \times 7 \\ 0.2x + 1 = 2.8 \\ 0.2x = 2.8 - 1 \\ 0.2x = 1.8 \\ x =  \frac{1.8}{0.2}  \\   \boxed{x = 9}

  • <u>x</u><u> </u><u>= 9</u> is the right answer.

Answer:

9

Step-by-step explanation:

0.2x+1/7=0.4

multiply 7 on both sides.

you get….

0.2x+1=2.8

Minus 1 on both sides.

0.2x= 1.8

divide .2 on both sides

x=9!

I hope you get it!!

Find the constant rate of change for each linear function and interpret its meaning
Marina CMI [18]

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

and to get it, we simply need two points off of the straight line, hmm let's use the ones in the picture below.

(\stackrel{x_1}{2}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{6}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{6}-\stackrel{y1}{4}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{2}}}\implies \cfrac{2}{4}\implies \cfrac{1}{2}

I need help fast please...
BARSIC [14]

Answer:

87: y = 5

88: y = 0

89: y = -2

90: y = -1/2x + 9

91: y = 2x - 16

92: y = x - 11


Step-by-step explanation:

To find the slope(m): (y1 - y2)/(x1 - x2)

To find the y-intercept:

y = mx + b

Replace m with the slope and x and y with one of the sets of coordinates. Then simplify to get the y-intercept. Use the equation y = mx + b and replace m with the slope and b with the y-intercept to get the equation.


(Sorry if this is a little confusing.)
