Mathematics
1 answer:
IRISSAK [1]3 years ago
3 0

Answer:

5220

Step-by-step explanation:

1- 20x36/2 is 360

(360 x 2 is 720)

2. 25x50 is 1250

3. 29x50 is 1450

4. 36x50 is 1800

720+1250+1450+1800 is 5220

Determine the standard form of the equation of the line that passes through (-6,6) and (3, -2)
viva [34]

Answer:

 (8/9)x +y = (2/3)

Step-by-step explanation:

General standard form of an equation of a line is y = mx+b, where m is the slope of the line and b is the y-intercept ( where the line intersects the y-axis.)

For points (-6, 6) and (3, -2)

m= (y2-y1)/(x2-x1) = (-2-6) / (3-(-6)) = -8 / 9

y = (-8/9)x +b

Substitute any of the 2 points to find b. If we choose (x=3, y= -2) then

-2 = (-8/9)*3 +b, simplify (-8*3)/9

-2 = (-8/3)+b, add (8/3) to both sides

-2+(8/3) = b, find the common  denominator and add the fractions

(-6+8)/3 =b

2/3 =b

The standard form of the equation of the line that passes through (-6,6) and (3, -2) is (8/9)x + y = (2/3)

What is the first step needed to solve 3 over 4 multiplied by x minus 3 equals negative 18 ? (1 point) a Add 3 to both sides b S
Sholpan [36]

Answer:

a

Step-by-step explanation:

3/4 x - 3 = -18

You should try to get all of one term on one side of the equation, and have the constant on the other side so the next step would be easy.

Here are the steps after you add 3:

3/4 x = -15

x = -5/4 (divide by 3/4 on both sides)

Which is equivalent to √3/√8 when denominator is "rationalized"?
TEA [102]

Step-by-step explanation:

\dfrac{\sqrt3}{\sqrt8}=\dfrac{\sqrt3\cdot\sqrt2}{\sqrt8\cdot\sqrt2}=\dfrac{\sqrt{3\cdot2}}{\sqrt{8\cdot2}}=\dfrac{\sqrt6}{\sqrt{16}}=\dfrac{\sqrt6}{4}

<h3>Used:</h3>

\sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\ \text{for}\ a\geq0\ \wedge\ b\geq0\\\\\sqrt{a}=b\iff b^2=a\ \text{for}\ a\geq0\ \wedge\ b\geq0\\\\\sqrt{16}=4\ \text{because}\ 4^2=16
