representing the number of chocolates remaining in the box t days after Zoe's
birthday.

Answers

Answer:

c=-3t+30

Stay safe

The expression for the number of chocolates remaining will be c = 24 - 4t.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that, Zoe was given a box of assorted chocolates for her birthday. Each night, she to some chocolates. Zoe ate 4 chocolates each night and after 3 nights, there were 12 chocolates remaining in the box.

Let the number of days be represented by t, and the number of chocolates will be C.

The total number of chocolates will be calculated as,

Total = 3 x 4 + remaining chocolates = 12

Total = 3 x 4 + 12

Total = 12

The expression will be written as,

C = 24 - 4t

Therefore, the expression for the number of chocolates remaining will be c = 24 - 4t.

O A. y = -1/2x+2
B. y = 2x + 6
O C. y = 2x-6
O D. y=-1/2x

Answers

Perpendicular equations have negative reciprocal gradients (so it’s gradient will be -1/2)

And if you draw a quick sketch of the lines A and D (they have the right gradients) then you can see which option is the best fit. I used desmos and option A passes through (-4,2)

Answer:

y= -1/2x

Step-by-step explanation:

perpendicular is the opposite slope so -1/2 is the opposite slope of 2y=mx+b to solve for b I was taught to plug in what you have so2= -1/2(-4)+b2=2+bsubtract 2 on both sides to get b=0

angle SVR = 30°angle PVR = 90°angle SVQ = 60°angle SVP = 120°angle RVQ = 30°

Step-by-step explanation:

As with finding distances on a number line, the easiest way is to subtract the smaller coordinate from the larger. Here, the "number line" is the arc at the edge of the protractor. The corresponding coordinates are ...

S: 40°

R: 70°

Q: 100°

P: 160°

The measure of an angle with its vertex at V will be the difference between the "coordinates" of the endpoints of the arc it intercepts. That is ...

m∠SVR = "R" - "S" = 70° -40° = 30°

The other angles are found the same way:

m∠PVR = 160° -70° = 90°

m∠SVQ = 100° -40° = 60°

m∠SVP = 160° -40° = 120°

m∠RVQ = 100° -70° = 30°

Answers

Answer: A) all real numbers

The domain is the set of all possible x inputs. The blue curve stretches on forever in both directions along the x axis. This means that we can plug in any x value we want, and get some y output. We don't have to worry about dividing by zero, or applying the square root of a negative number, so there are no restrictions on the domain. We can take the cube root of a negative number with no issues. For example, the cube root of -8 is -2.
