Write an equation the describes the line passing through point (1/2, 0) with slope - 1
Answers
Answer:
Your equation is [tex]y = -1x + \frac{1}{2}[/tex] or [tex]y = -1x + .5[/tex]
Step-by-step explanation:
Equation of the line: [tex]y=mx+b[/tex]
Add in the slope in place of ([tex]m[/tex])
[tex]y=-1x+b[/tex]
Add in the x value of the given point in place of ([tex]x[/tex])
[tex]y=(-1)\frac{1}{2}+b[/tex]
Add in the y value of the given point in place of ([tex]y[/tex])
[tex]0=(-1)\frac{1}{2} + b[/tex]
—
Solve:
[tex]0=(-1)\frac{1}{2} +b[/tex]
Multiply -1 and [tex]\frac{1}{2}[/tex]
[tex]-1 *\frac{1}{2}=-\frac{1}{2}[/tex]
So,
[tex]0=-\frac{1}{2} +b[/tex]
Now, add [tex]-\frac{1}{2}[/tex] to 0
[tex]0=-\frac{1}{2} +b[/tex]
[tex]+\frac{1}{2}[/tex] [tex]+\frac{1}{2}[/tex]
---------------------------
[tex]\frac{1}{2} = b[/tex]
Replace ([tex]b[/tex]) with [tex]\frac{1}{2}[/tex]
Your equation is [tex]y = -1x + \frac{1}{2}[/tex] or [tex]y = -1x + .5[/tex]

After all, tryouts are completed, the school will be hosting a party for all the new athletes. At the party, hot dogs and hamburgers will be provided to all athletes and their guests, if they choose to bring a guest. The ratio of hot dogs purchased to a number of guests is 1:0.8. Determine how many hot dogs you would need if 150 people attend the party.
Answers
Explanation:
h = number of hot dogs
The ratio of people to hot dogs is 1:0.8
If 150 people show up to the party, then
(number of people)/(number of hot dogs) = 1/0.8
150/h = 1/0.8
150*0.8 = h*1 ... cross multiply
120 = h
h = 120
You'll need 120 hot dogs.

he area of a rectangular piece of metal is 20 square centimeters. The perimeter is 18 centimeters. What are the dimensions of the piece?
Answers
Answer:
5 cm by 4 cm
Step-by-step explanation
A = L x W 20 = L x W
P = 2L + 2W (18 = 2L + 2W)/2
9 = L + W W = 9 - L
20 = L (9 - L) 20 = 9L - L^2
L^2 - 9L + 20 = 0 (L - 4)(L - 5) = 0
L = 4 L = 5
The longer one is the length, so L = 5, and W = 4.

The answer is x = 50.The measure of x is 50.
What are Vertical Angles?Vertical angles are generated by the junction of two straight lines that are not contiguous. Vertical angles are positioned across from each other in the corners of the "X" created by two straight lines. Because they are opposite each other, they are also known as vertically opposite angles.
Using Vertical Angle property as
(50+ 2x) = 150
So, subtract 50 from side we get
50 + 2x - 50= 150 - 50
2x = 100
Now, divide both side by 2 we get
2x/2 = 100 / 2
x = 50
