Quadratics formula 4x^2+3x-1=0
VARVARA [1.3K]

Answer: X = 1/4 or X = -1

Step-by-step explanation:

4x2+3x−1=0

(4x−1)(x+1)=0

4x−1=0 or x+1=0

4x=1 or x=-1

Now divide 4 from both sides

like this 4x/4=1/4

now cancel out two 4's so the answer will be x=1/4

Olivia is making model cars to go on shelves in her room. The number of wheels she uses is a function of how many cars she makes
Luba_88 [7]

Answer:

Domain = 1 to 7

Range = 4 to 28

Step-by-step explanation:

Given that:

Number of wheels used is a function of number of cars manufactured.

Number of wheels present = 28

1 car uses 4 wheels

2 cars use 8 wheels.

3 car uses 12 wheels

and so on.

Let the function be of the form:

y =f(x)

Domain of the function is the value of x that can be given as valid input to the function.

Range of the function is the value of y that can be output of the function.

Let x be the number of cars manufactured.

Then value of y is nothing but x times 4.

y=4x

We are given that maximum value of y can be 28.

28 = 4x\\\Rightarrow x =7

Therefore, maximum value of input can be 7.

Minimum number of wheels can be 4 to make a minimum of 1 car.

Therefore domain is 4 to 28 and range is 1 to 7.
