Answer:

<h3> Perimeter = 3√5 + 6 + √73 + √58 + 5√2</h3>

Step-by-step explanation:

$AB=\sqrt{(6-0)^2+(5-8)^2}=\sqrt{36+9}=\sqrt{45}=3\sqrt5\\\\BC=|-1-5|=|-6|=6\\\\CD=\sqrt{(-2-6)^2+(-4-(-1))^2}=\sqrt{64+9}=\sqrt{73}\\\\DE=\sqrt{(-5-(-2))^2+(3-(-4))^2}=\sqrt{9+49}=\sqrt{58}\\\\EA=\sqrt{(0-(-5))^2+(8-3)^2}=\sqrt{25+25}=\sqrt{25\cdot2}=5\sqrt2$

Question 5 show the work please

Pani-rosa [81]

Answer:

D) 27

Step-by-step explanation:

It's a rectangle so the opposite sides are congruent to each other.

Long Side:

6x + 6 = 42

subtract 6 from both sides:

6x = 36

divide both sides by 6:

x = 6

Short Side:

5y + 5 = 30

subtract 5 from both sides:

5y = 25

divide both sides by 5:

y = 5

The Equation:

2x + 3y

substitute in the values:

2(6) + 3(5)

do the multiplication:

12 + 15

add the values together:

Which of the following is 3 units lower than y = 4x2 – 8x + 2, but opens in the same direction and has the same shape?

olga_2 [115]

Simplify the function $y=4x^2-8x+2$ in the following way:

$y=4x^2-8x+2=4x^2-8x+4-4+2=4(x^2-2x+1)-2=4(x-1)^2-2.$

If you have to translate the graph of the function 3 units lower (down), then

$y=4(x-1)^2-2-3=4(x-1)^2-5.$

The graph of obtained function opens in the same direction as the graph of the function $y=4(x-1)^2-2.$

Answer: $y=4(x-1)^2-5.$

7y+3x+3-2y+6......please help I need the coefficient of y and what is the constant?

katrin [286]

Answer:

5 is the coefficent of y if you simplify and 3 is the constant

Step-by-step explanation:

7y-2y=5y. The coefficient is the number that goes with the variable, or letter, such as y. The constant is the number that does not have any coefficients attached to it.

Through: (1,-1), parallel to y = -3

zheka24 [161]

Answer:

The equation of a line parallel to the line and passing through (1, -1) is:

$y=-3x+2$

Step-by-step explanation:

Given the line

y = -3

We know that the slope-intercept form of the line equation is

$y=mx+b$

where m is the slope and b is the y-intercept

Thus, the slope of the equation y=-3 will be m = -3

We know that the parallel lines have the same slopes.

Thus, the slope of the parallel line will also be -3.

Thus, using the point-slope form to find the line equation is

$y-y_1=m\left(x-x_1\right)$

substituting the values m = -3 and the point (1, -1)

y-(-1) = -3(x-1)

y+1 = -3x+3

y=-3x+3-1

y=-3x+2

Thus, the equation of a line parallel to line and passing through (1, -1) is:

$y=-3x+2$
