Answers
Answer:
-1/2 or -0.5
negative half
Step-by-step explanation:
slope of regular line= (y1-y2) / (x1-x2)
(27-3) / (4 - -8)
24 / (4+8)
24 / 12 = 2
the slope of a perpendicular line is the negative reciprocal

HELP!! 2. in the figure, x is an exterior angle to the triangle below.
a) explain why x is equal to the sum of the measures of the two nonadjacent interior angles. You need to present the equation with the steps/work that proves this theorem.
Step 1: __ Step 2: __ Step 3: __
(b) what is the measurement of < x ?
Answers
Answer:
< x = 120°
Step-by-step explanation:
Step 1:
According to angle sum property,
y + 50 + 70 = 180
Step 2:
x and y are linear pairs, forming a supplementary angle.
Therefore,
x + y = 180
Step 3:
Since they are both equal to 180, equate the values
y + 50 + 70 = x + y
x = 70 + 50
x = 120

Gabriella needs 120 meters of fence to surround a rectangular garden.
The length of the garden is three times its width, w.
How wide is the fence?
Answers
To fence a rectangular garden, we need to fence the length 2 times, and the width 2 times.
So, it will take 120 : 2 = 60 meters of fence to fence 1 length and 1 width
-> The length = 60 : (3+1)x3 = 45 (meters)
-> The width = 60 - 45 = 15 (meters)
Recheck : (45+15) x 2 = 120 and 45:15 = 3
(If it's wrong you can tell me, I don't really know what do you mean by how wide is the fence)
The width of the rectangular garden, for which Gabriella needs 120 meters of fence to surround it is 15 units long.
What is the perimeter of a rectangle?The measure of the boundary of the sides of a rectangle is called its perimeter. The perimeter of a rectangle is twice the sum of its length and width.
[tex]P=2(l+w)[/tex]
Here, (l) is the length of the rectangle and (w) is the width of the rectangle.
Let suppose the length of the garden is l units long. The length of the garden is three times its width, w. Thus,
[tex]l=3w[/tex]
Gabriella needs 120 meters of fence to surround a rectangular garden. This fencing is equal to the perimeter of the rectangular garden. Thus,
[tex]P=2(l+ w)\\120=2(l+ w)[/tex]
Put the value of length from equation 1 to this equation,
[tex]120=2(3w+ w)\\3w+w=\dfrac{120}{2}\\4w=60\\w=\dfrac{60}{4}\\w=15\rm\; units[/tex]
Thus, the width of the rectangular garden, for which Gabriella needs 120 meters of fence to surround it is 15 units long.

The value of b for the provided quadratic equation, for which the only solution of the equation is x=4, is -8.
What is a quadratic equation?A quadratic equation is the equation in which the unknown variable is one and the highest power of the unknown variable is two.
The standard form of the quadratic equation is,
[tex]ax^2+bx+c=0[/tex]
Here, (a,b,c) are the real numbers and (x) is the variable.
The given quadratic equation in the problem is,
[tex]x^2 +bx +16 = 0[/tex]
The only solution of the equation is x = 4. Thus, put the value of x in the above equation.
[tex]\begin{aligned}\\(4)^2 +b(4) +16 &= 0\\16+4b+16&=0\\4b&=-32\\b&=-\dfrac{32}{4}\\b&=-8\\\end[/tex]

Choose one of the choices below
2/7=−5x+3
x=−20 1/2
x=−19
x=−16
x=−14 1/2
Answers
Answer:
(a) -20 1/2
Step-by-step explanation:
The proportion can be solved using "cross multiply" as the first step. This eliminates the fractions and turns it into a linear equation.
2/7 = -5/(x +3) . . . . . given
2(x +3) = -35 . . . . . . multiply by 7(x +3)
2x = -41 . . . . . . . . . simplify, subtract 6
x = -20 1/2 . . . . . . divide by 2
