You have to divide the numbers and get the answer for the last long ones you have to subtract or add the middle number and the right one

divide all both sides by the number with the x

for example 18 = 2x would be 9

18 divided by 2 is 9

2 divided by 2 would be canceled out.

so x would be 9

Annette [7]

Answer:

Step-by-step explanation:

let the longer tape be x

shorter tape be y

given

x+y=135⇒equation 1

also given

2y=x⇒equation 2

subtituting eq2 in eq1

2y+y=135

3y=135

y=135/3=45

Find the average rate of change of a function that contains the points

ELEN [110]

Answer:

1 / 2

Step-by-step explanation:

The average rate of change is the same as the slope.

Slope formula: (y₂ - y₁) / (x₂ - x₁)

= (5 - 3) / (2 - (-2))

= 2 / 4

= 1 / 2

Write an equation of the line that passes through the given points.<br> (-2,5) and (1,2)

Anon25 [30]

$\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{2}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{2}-\stackrel{y1}{5}}}{\underset{run} {\underset{x_2}{1}-\underset{x_1}{(-2)}}}\implies \cfrac{-3}{1+2}\implies \cfrac{-3}{3}\implies -1$

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{5}=\stackrel{m}{-1}[x-\stackrel{x_1}{(-2)}] \\\\\\ y-5=-(x+2)\implies y-5=-x-2\implies y=-x+3$
