Answer:
y=x−3
Step-by-step explanation:
x−y=3
Step 1: Add -x to both sides.
x−y+−x=3+−x
−y=−x+3
Step 2: Divide both sides by -1.
−y/−1=−x+3/1
y=x−3

In a quadratic function, recall that the discriminant D = b2 - 4ac. For which function is it true that a < 0 and D = 0?
Answer:
If D = 0, then the quadratic equation has 1 solution x = − b/2a
Step-by-step explanation:
If we have a quadratic equation x² +3x-4= 0
Then the corresponding values of a= 1, b=3, c= -4
Finding the discriminant gives
D= b2 - 4ac.
D= 3²- 4(1) (-4)
D= 9 + 16
D= 25
Here a> 0
But if a< 0 e.g a= -1
D= b2 - 4ac.
D= 3²- 4(-1) (-4)
D= 9 - 16
D= -7
Here a < 0 so we get the answer -7 < 0
D= b2 - 4ac.
D= 4²- 4(-1) (-4)
D= 16 - 16
D= 0
Here a< 0 and b= - c so that D= 0
When D < 0 roots do not exist.
If D = 0, then the quadratic equation has 1 solution x = − b/2a
This can be found out by using the quadratic formula
x= -b±√b²- 4ac/ 2a
But D= 0
x= -b±0/ 2a
x= -b/2a

Milo recorded the number of hours he worked and the total amount he earned, including tips. Let h be the number of hours he worked, and let y be the total amount he earned, including tips. The equation of a line of best fit of his data is y = 12.5h +3.85. Based on the equation of the line of best fit, how much money should Milo expect to earn if he works a 5-hour shift?
Answer:
$66.35
Step-by-step explanation:
To find this answer with y=mx+b, we should first explain what it is. Y is our output or answer. M is our variable and x is the slope of our variable or how often it occurs. B, is our y intercept, our initial starting amount. Knowing this, we must figure out y. To do this we must multiply his hourly wage by the hours he works which is $12.50x5. This will get us $62.50. Now that we know how much he makes hourly, we add his initial wage of $3.85 to get us $66.35
This means he will make $66.35 if he works a full 5 hour shift.
Answer:
66.35

What is the perimeter of the rectangle?
Answer:
10 feet
Step-by-step explanation:
Perimeter of rectangle = 2l+2b
Area of the rectangle = l x b
Area of the rectangle = 4 square feet
possible factors of 4 = 2x2/4x1
So sides of the rectangle are 4 & 1 as 2&2 would make it a square
So perimeter= 2x4+2x1
= 8+2
= 10 feet
A rectangle has a perimeter of 72 millimeters and a width of 8 millimeters. What is the length of this rectangle?
Answer:
28
Step-by-step explanation:
Since the perimeter is the width + width + length + length, we know that there 2 of the 8 millimeter width in the perimeter. So multiply 8 by 2, which is 16. So 16 of the 72 represents both widths. So subtract 16 from 72. You're left with 56, which represents 2 of the length. So divide 56 by 2, and you get one of the length, which is 28.

28 ^^

Find the expected value of the winnings from a game that has the following payout probability distribution. Round to the nearest hundreath.
The expected value of the winnings from a game will be [tex]2.96[/tex] .
What is Probability ?Probability is the ratio of the number of possible outcomes to the total number of outcomes.
we have,
Payout [tex](\$) = 0,\ \ \ 1,\ \ \ 2,\ \ \ 5,\ \ \ 10[/tex]
Probability [tex]=0.12,0.2,0.38,0.2,0.1[/tex]
So,
To find the expected value,
Now,
Multiply payout values with its probability and sum these values,
i.e.
Expected value [tex]= (0*0.12)+(1*0.2)+(2*0.38)+(5*0.2)+(10*0.1)[/tex]
[tex]=0+0.2+0.76+1+1[/tex]
Expected value [tex]=2.96[/tex]
Hence, we can say that the expected value of the winnings from a game will be [tex]2.96[/tex] .

For adults, a bowling alley charges $3.75 for shoe rental and $5 per game. For children, the cost is $2.50 for shoe rental and $4 per game. What expression represents the total cost for one adult and one child to bowl g games?
Answer:
1x+1y= 9
x= adults y= children 9= the amount they have to pay to play a game if its 1 adult and 1 child
The expression represents the total cost for adults and children:-
Ca = $3.75 + 5g
Cc = $2.50 + 4g
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that for adults, a bowling alley charges $3.75 for shoe rental and $5 per game. For children, the cost is $2.50 for shoe rental and $4 per game.
For adults the expression will be:-
Ca = $3.75 + 5g
For children, the expression will be:-
Cc = $2.50 + 4g
Hence, the expression are Ca = $3.75 + 5g and Cc = $2.50 + 4g.

Last week, Pamela spent 2 3/4 hours watching television. Miranda watched television for 1/2 as many hours as Pamela did. How many hours did Miranda spend watching television?
Answer: [tex]\dfrac{11}{8}\ hr[/tex]
Step-by-step explanation:
Given
Pamela spent [tex]2\ \frac{3}{4}\ hr[/tex] watching television
Miranda watched half as many hours as Pamela did
