sketch the linear equation 2x+y=35
Answer: Here, i graphed it on desmos
Answer:
Step-by-step explanation:
You want to get the Y alone so what you would do is move the 2x on the others side of the equation which changes the sign to a negative and now it should look like this: y=-2x+35. Then you sketch it on a graph. Hopes this helped!

Brainliest pls? Have a good day/night
The total revenue of the carnival expected after spending 2 weeks is 58,931.
Option B is the correct answer.
What is a percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
We have,
Revenue at the first night = $15,000
Each night after the first night, revenue will be about 75% of the previous night's revenue.
75% = 75 / 100 = 3/4
We need to find the total revenue collected after 14 days.
1 day -
= 15000 ____(1)
2 day -
= 3/4 x 15000
= 11250 _____(2)
3 day -
= 11250 x 3/4
= 8438 _______(3)
4th day -
= 8437.5 x 3/4
= 6328 ______(4)
5th day -
= 4746 _______(5)
6th day -
= 3560 ______(6)
7th day -
= 2670 ______(7)
8th day -
= 2002 ______(8)
9th day -
= 1502 ______(9)
10th day -
= 1126 _______(10)
11th day -
= 845 ______(11)
12th day -
= 634 _____(12)
13th day -
= 475 ______(13)
14th day -
= 356 _______(14)
Adding (1) to (14)
We see that the total revenue is 58931.
Thus the total revenue of the carnival expected after spending 2 weeks is 58,931.
Option B is the correct answer.

You are helping Folsom's city manager adjust traffic patterns for the new residents south of Hwy 50. A traffic light changes every 30 seconds. Another traffic light changes every 40 seconds. Both lights just changed. After how many minutes will both lights change at the same time again? (Hint - find the LCM of 30 and 40.) Why does your answer make sense?
Answer:
120 minutes
Yes my answer makes sense
Step-by-step explanation:
This question has to do with Lowest Common Multiples
1) After how many minutes will both lights change at the same time again?
Step 1
We would find and list multiples of each number until the first common multiple is found.
Multiples of 30:
30, 60, 90, 120, 150, 180
Multiples of 40:
40, 80, 120, 160, 200
Step 2
The first common multiple of 30 aand 40 is the lowest common multiple.
Therefore,
LCM(30, 40) = 120
Therefore, both lights will change at the same time after 120 minutes.
2) Why does your answer make sense?
Lowest common multiple is a methodology used in mathematics to show the relationship between two numbers based on their multiples.
My answer makes sense because the only way both traffic light would come up at the same time can only be determined using the methodology of Lowest Common Multiple.
Hence, both lights will change at the same time after 120 minutes.

Which fraction below represents a terminating decimal?
A. 1/12
B. 2/9
C. 3/10
D. 2/3
A terminating decimal only happens when the fraction has a denominator with factors of 2 and/or 5. No other factors are allowed (other than 1).
Something like 1/12 has the denominator 12 with factors 2*2*3. That '3' means we won't have a terminating decimal. Similarly, the fractions 2/9 and 2/3 won't convert to a terminating decimal either.
3/10 on the other hand does convert to a terminating decimal and 3/10 = 0.3
Evaluate f(x) = -4x + x2 + 16 for f(-4).
Answer:
[tex]f(-4)=48[/tex]
Step-by-step explanation:
Value of functions
To evaluate a function for a given value of x, we replace the x for the value and perform the resulting operations.
The given function is (corrected):
[tex]f(x)=-4x+x^2+16[/tex]
We need to find f(-4), so we use x=-4:
[tex]f(-4)=-4*(-4)+(-4)^2+16[/tex]
[tex]f(-4)=16+16+16[/tex]
[tex]\boxed{f(-4)=48}[/tex]

what’s the domain using inequalities for this graph?
Answer:
-9 ≤ x < 2
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We can see from the graph that our x-values span from -9 to 2. Since -9 is closed dot, we include it in our domain. Since -2 is open dot, it is excluded from our domain:
[-9, 2) or -9 ≤ x < 2
