Answer:
y = -1x + 6 or y = -x + 6
Step-by-step explanation:
First, let's identify what slope-intercept form is.
y = mx + b
m is the slope. b is the y-intercept.
We know the slope is -1, so m = -1. Plug this into our standard equation.
y = -1x + b
To find b, we want to plug in a value that we know is on this line: (2, 4). Plug in the x and y values into the x and y of the standard equation.
4 = -1(2) + b
To find b, multiply the slope and the input of x(2)
4 = -2 + b
Now, add 2 from both sides to isolate b.
6 = b
Plug this into your standard equation.
y = -1x + 6
This is your equation.
Check this by plugging in the point again.
y = -1x + 6
4 = -1(2) + 6
4 = -2 + 6
4 = 4
Your equation is correct.
Hope this helps!

The admission fee at a John Hay basketball game is $1.50 for students and $4.00 for adults. On a certain day, 2200 people enter the fair and $5050 is collected.
How many of each type of ticket did they sell?
Student:
and
Adult
Answer:
See below, please!
Step-by-step explanation:
We can set up a system of equations to model this problem. Let's consider the student's ticket as x, and y for the adult ticket.
So since the student ticket is $1.50, and adult is $4, we can set up the following equation: [tex]1.5x+4y=5050[/tex], since they collected $5050 total.
We can set up another equation modeling the number of people who came to the game. This would be x+y=2200.
Solve this, and we get x= 1500 and y=700. So, they sold 1500 student tickets and 700 adult tickets.

Answer:
a) $2.40
b) $16.80
c) y = -2.40x +16.80
Step-by-step explanation:
a. Dylan's daily spending is the opposite of the slope of the line on the graph. That slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (4.8 -12)/(5 -2) = -7.2/3 = -2.4
Dylan spends $2.40 at lunch every day.
__
b. The y-intercept can be found from the formula ...
b = y1 -m(x1)
b = 12 -(-2.40)(2) = 16.80
Dylan's dad gives him $16.80 at the beginning of each week.
__
c. The slope-intercept equation is ...
y = mx + b
y = -2.40x +16.80

I know this isnt a question but I have act in a few days and I've been doing remote learning online for all of 11th grade and I've been failing because of it, I just don't know what to do :(
Im a c/b average student and because of this year and my home life and me starting a month late I was set up to fail really, I do 3-4 hours every day even weekend (sometimes i can only do 2) but I feel like I'm gonna fail and ive never failed before.
Is there anything I can do or anything I can study for the act?

What is the measure of angle DEG on circle O
9514 1404 393
Answer:
50°
Step-by-step explanation:
Angle DEG is also angle DEC. It subtends arc DC as does inscribed angle DFC. Inscribed angles that subtend the same arc have the same measure.
∠DFC = ∠DEG = 50°
Answer: 50

this is my last question please help me
Answer:
Angle ADC = 80 degrees
Step-by-step explanation:
Here, we want to find the measure of angle ADC
mathematically, sum of angles at a point is 360
Thus;
x + 3x + x + 10 = 360
5x + 10 = 360
5x = 360-10
5x = 350
x = 350/5
x = 70
From the diagram;
angle ADC is (x + 10)
so we have; (70 + 10) = 80 degrees
A 60$ purse is on sale for 10% give the sell price
Answer:$54
Step-by-step explanation:
60(0.9) = $54
answer:
$54
step-by-step explanation:
sale means a decrease from the original amountsince there is a sale of 10%, we would multiply by 90% since we are trying to find the sale price60 X 90% - - > 60 X 0.90
you can convert 90% into 0.90 so it is easier to multiply60 X 0.90 = 54
= $54

which lines are parallel or perpendicular? line A:(-4,-1)(2,-2)line B:(-5,-3)(5,1) line C:(-2,-3)(2,-1)
Answer:
none of the lines are parallel or perpendicular to each other
Step-by-step explanation:
which lines are parallel or perpendicular? line A:(-4,-1)(2,-2)line B:(-5,-3)(5,1) line C:(-2,-3)(2,-1)
in order to know which lines are parallel or perpendicular, we need to find the slopes of the lines given
Slope M = y2-y1/x2-x1
For line A;
Ma = -2+1/2+4
Ma = -1/6
Slope of line A is -1/6
For line B;
Mb = 1 -(-3)/5-(-5)
Mb = 1+3/5+5
Mb = 4/10
Mb = 2/5
The slope pf line B is 2/5
For line C;
Mc = -1-(-3)/2-(-2)
Mc = -1+3/2+2
Mc = 2/4
Mc = 1/2
Hence the slope of line C is 1/2
Since all the slopes are different , hence none of the lines are parallel or perpendicular

Combine the like terms -6m + 4m. Simplify your answer
Answer:
-2m
Step-by-step explanation:
-6m + 4m
Combine like terms by performing the operation between the coefficients. In this case, one must add the different coefficients, yet since one of the coefficients is negative, then adding the two coefficients is the same as subtracting the two terms.
-6m + 4m
= -2m

The sum of numbers is 28. the difference of two numbers is -2. find the numbers
Answer:
x=13 and y=15
Step-by-step explanation:
Let the 2 numbers be x and y
ATQ,
x+y = 28 ------ eqn.1
x-y=-2 -------- eqn.2
Adding both the equations:
x+y=28
+x-y=-2
_______
2x = 26
Therefore x=13
Now substituting the value of x in eqn. 1
x+y=28
13+y=28
Therefore y=28-13
=15
