what type of function is y=3x-2
Step-by-step explanation:
Explanation: y=3x+2 is not a function. Rather, it is just a regular linear equation.
It's not.
Explanation:
y=3x+2
is not a function. Rather, it is just a regular linear equation. However,
f(x)=3x+2
is a function, because it contains "
f(x)."
So, in general, if it contains " y ," then you are safe in assuming that it is an equation. If it contains "
f(x) ," then you are safe in assuming that it is a function.
I hope that helps!
The function y = 3x - 2 is a linear function.
Given data:
The function is represented as y = f ( x )
The value of y = 3x - 2
The equation y = 3x - 2 represents a linear function.
The function has a constant rate of change, which is 3, as the coefficient of x. The function forms a straight line when graphed on a Cartesian coordinate plane.
The term "linear" indicates that the relationship between x and y is of the first degree, meaning there are no exponents or other nonlinear components involved.

Factorise 15x² + 9xy + 3x
Answer:
Step-by-step explanation:
15x² = 3⋅5x²
9xy = 3²xy
15x² + 9xy + 3x = 3x(5x + 3y + 1)
The factored form of the expression 15x² + 9xy + 3x is 3x(5x + 3y + 1).
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To factorize 15x² + 9xy + 3x, we can factor out the greatest common factor of the three terms, which is 3x:
15x² + 9xy + 3x = 3x(5x + 3y + 1)
Therefore,
The factored form of 15x² + 9xy + 3x is 3x(5x + 3y + 1).

Step-by-step explanation:
Ethan has $620 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $427.57. He buys 4 bicycle reflectors for $11.38 each and a pair of bike gloves for $31.41. He plans to spend some or all of the money he has left to buy new biking outfits for $57.75 each. Write and solve an inequality which can be used to determine oo, the number of outfits Ethan can purchase while staying within his budget.
Answer: 620≥ 427.57+ 11.38(4)+ (31.41) +57.75x
Step-by-step explanation:
So our limit is the 620$ that he has to spend. We know for a fact that the bike costs about 427.57 dollars. 4 $11.38 reflectors are purchased as well as gloves for 31.41. Now however many outfits he can purchase cannot exceed or go over his money limit of 620 so the variable (x) represents how many outfits he can buy without going over.
We are required to write an inequality for the problem and also solve it
The number of biking outfit Ethan can purchase is 2
Given:
Total amount Ethan has = $620
Amount of bicycle = $427.57
Bicycle reflector = $11.38
Cost of 4 Bicycle reflector = $11.38 × 4
= $45.52
Cost of bike glove = $31.41
Cost of biking outfit = $57.75
Write an inequality to solve for the number of biking outfit Ethan can purchase
let
x = number of biking outfit Ethan can purchase
620 ≥ 427.57 + 45.52 + 31.41 + 57.75x
620 ≥ 504.5 + 57.75x
620 - 504.5 ≥ 57.75x
115.5 ≥ 57.75x
x ≥ 115.5 / 57.75
x ≥ 2

Plz help i dont get any of these type of questions T-T
Answer:
Exact: [tex] 11 \pi~in.^2 [/tex]
Approximate: [tex] 34.6~in.^2 [/tex]
Step-by-step explanation:
The spaces the clocks occupy on the wall are the areas of the clocks.
The clocks are shaped like circles, so use the formula for the area of a circle to find the two areas. Then subtract the smaller area from the larger area.
[tex] A_{circle} = \pi r^2 [/tex]
Larger clock, r = 6 in.
[tex]A_{large~clock} = \pi \times (6~in.)^2 = 36 \pi ~in.^2 = 113.1~in.^2[/tex]
Smaller clock, r = 5 in.
[tex]A_{small~clock} = \pi \times (5~in.)^2 = 25 \pi ~in.^2 = 78.5~in.^2[/tex]
Difference in areas:
Exact: [tex] 36 \pi~in.^2 - 25 \pi~in.^2 = 11 \pi~in.^2 [/tex]
Approximate: [tex] 113.1~in.^2 - 78.5~in.^2 = 34.6~in.^2 [/tex]

In triangle ABC, A is a right angle and M B=45°. Find BC. If you answer is not an integer, leave it in simplest radical form.
Step-by-step explanation:
- In a right triangle, if ∠B is 45°, then ∠C is too.
-- Since ∠B and ∠C are equal, the sides opposite them
are equal too. This is an isosceles right triangle. Its legs
are equal.
-- (The hypotenuse)² = (one leg)² + (the other leg)²
= (12-ft)² + (12-ft)²
= (144 x 2)
The hypotenuse = √(144 x 2) = 12√2 .
