35. All you have to do is add the whole numbers and then u add the decimal point, so it would be 12.23.
36. The answer would be 0 because you are multiplying and when u multiply with a 0 the product is always 0.
37.You just have to multiply the numbers together normally and ignore the decimal point, when you are done you just have to move the decimal point over 1 space.

Using the given equation y-3 = 3/4(x+2)

Give Y a value and then solve for x:

If y = 0 the equation is now:

0 -3 = 3/4(x+2)

Solve for x:

-3 = 3/4x + 1.5

-4.5 = 3/4x

x = -4.5 / 3/4

x = -6

So the first point would be (-6,0)

Now make x 0 and solve for y:

y -3 = 3/4(0+2)

y-3 = 0 + 1.5

y = 4.5

So the 2nd point would be (0,4.5)

You are close, but the dot you have on y=4, needs to be moved up to 4.5.

2x-4y=-16
ax+4y=6 +
--------------------
2x+ax=-10; for x=-2,
2(-2)+a(-2)=-10
-2a=-10+4
a=-6/-2
a=3

A rectangle is 20 meters long and 20 meters wide. If the length is increased by 10% and the width is decreased by 10%, what is t

Solnce55 [7]

Consider that the initial length and width of the rectangle are given as,

$\begin{gathered} l=20 \\ b=20 \end{gathered}$

After the length is increased by 10%, the new length (L) of the rectangle is calculated as,

$\begin{gathered} L=(1+\frac{10}{100})\cdot l \\ L=(\frac{110}{100})\cdot20 \\ L=22 \end{gathered}$

After the width is decreased by 10%, the new width (B) of the rectangle is calculated as,

$\begin{gathered} B=(1-\frac{10}{100})\cdot b \\ B=(\frac{90}{100})\cdot20 \\ B=18 \end{gathered}$

Then the area (A) of the new rectangle is calculated as,

$\begin{gathered} A=L\times B \\ A=22\times18 \\ A=396 \end{gathered}$

Thus, the new area of the rectangle is 396 square meters.
