What is the domain and range of this graph?

Mama L [17]

Domain: (-1, 5)
Range: (-1, 3)

Explanation:
The domain covers the lowest and highest x value. You take the lowest number for the x and the highest number and that’s your domain. The range is covering y values, so you look at the lowest and highest point on your graph

List the steps that should be used to solve the equation f(x) = g(x) by graphing when f(x) = (1/2)² - 3 and g(x) = 3x + 5?

jolli1 [7]

value of x is: $x=\frac{-31}{12}$

Step-by-step explanation:

We need to solve the equation f(x)=g(x)

where $f(x)=(\frac{1}{2})^2-3$

and $g(x) = 3x + 5$

Solving to find f(x)=g(x)

Putting values of f(x) and g(x)

$f(x)=g(x)\\(\frac{1}{2})^2-3=3x + 5\\\frac{1}{4}-3=3x + 5\\Subtarct\,\,5\,\,on\,\,both\,\,sides:\\\frac{1}{4}-3-5=3x + 5-5\\\frac{1}{4}-8=3x\\Taking\,\,LCm\,\,on\,\,left\,\,side\\\frac{1-8*4}{4}=3x\\\frac{-31}{4}=3x\\Divide\,\,both\,\,sides\,\,by\,\,3\\x=\frac{-31}{4*3}\\x=\frac{-31}{12}$

So, value of x is: $x=\frac{-31}{12}$

The graph will be a straight line x= -2.58 or x = -31/12

A) (12 ft)/(2 3/8 ft) = 5 1/19

The maximum height of a stack of boxes is 5 boxes.

b) (1/19)*(2 3/8 ft) = 1/8 ft is the room left at the top of the stack.

Alexander is a high school basketball player. In a particular game, he made some two point shots and some three point shots. Ale

andrezito [222]

Answer:

2 three points shots and 4 two points shots

Step-by-step explanation:

Let x be the number of three points shots.

Alexander made twice as many two points shots as three points shots, so the number of two points shots is 2x.

Amount earned in three points shots $=3\cdot x$

Amount earned in two points shots $=2\cdot (2x)=4x$

Total score $=3x+4x=7x$

Alexander scores a total of 14 points, then

$7x=14\\ \\x=2\\ \\2x=2\cdot 2=4$
