Which equation is a function of x?
x = 5
x = y squared + 9
x squared = y
x squared = y squared + 16

Answers

Answer:

x squared = y

Step-by-step explanation:

Functions

Things can get more complicated, but based on the examples given, for an equation to be a function of x, it must have a single y, where the y is not raised to a power.

Option 1:  x=5

This equation doesn't have a y, so it isn't a function of x.

Option 2:  x = y squared + 9

This equation has y raised to a power, so it isn't a function of x

Option 3:  x squared = y

This equation has a y, and the y isn't raised to a power.  This is a function of x.

Option 4:  x squared = y squared + 16

This equation has y raised to a power, so it isn't a function of x

Determining functions graphically

If the equations are graphed, the graphs must pass a vertical line test (a vertical line drawn anywhere should not intersect the graph more than once).


Option 1:  x=5

x=5 represents a vertical line, so it fails the vertical line test (the vertical line would overlap and intersect it infinitely many times).

Option 2:  x = y squared + 9

x = y squared + 9 is a sideways parabola.  A vertical line will cross it twice in several places

Option 3:  x squared = y

x squared = y is a parabola that opens upward.  It will pass the vertical line test

Option 4:  x squared = y squared + 16

x squared = y squared + 16 is a hyperbola (fancy graph shape) that won't pass the vertical line test.

Make a number line and show all values of x. x≤2 and x< -5

Answers

Answer:

X<-5

Step-by-step explanation:

X has to be <-5 and <=2

If you draw a number line, you can see clearly that - 5 become first than 2.

If the condition is that it has x≤2 and x< -5, you don't take the values between - 5 and 2, cause the 2nd condition makes the result ]-infinity;-5[

I think I know the Pentagon one. I believe it'd be 225 yd.

The rectangle is 15 multiplied by 12, which is 180. And because the triangle is not a right triangle, you can just think of it as a rectangle that was broken apart. So 3 multiples by 15, 45. Add 45 and 180 to get the answer.

As it is equilateral triangle, l₁ = l₂ = b = 6 cm

Total surface area of triangular prism= (l₁ +l₂ + b)* height

                                                                 = ( 6 + 6 + 6) * 15

                                                                 = 18 * 15

                                                                 = 270 cm²

2) length = l = 8.2 in

Width = w = 3.4 in

height = h = 2

Total surface area of rectangular prism = 2*(lw + wh + hl)

= 2*(8.2*3.4  +  3.4*2  + 2*8.2)

=2 *( 27.88 + 6.8 + 16.4)

= 2 * 51.08

3x+4=7 solve equation with work.

Answers

X=1
3+4=7
3x1=3
3+4 =6 so X =1

Answer:

X=1

Step-by-step explanation:

reverse multiplication -

7=4+3x

we know one value so we just isolate the 3x

7-4=3, meaning that 3x has to be equal to 3.

Then we just do 3/3=1 so therefore x=1

Also if you wanna check it then you can plug x=1 into the equation.

4+3*x or 1=4+3=7

Explain how you use substitution to solve a system of linear equations.

Answers

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

Answer:     Step 1 : First, solve one linear equation for y in terms of x .

   Step 2 : Then substitute that expression for y in the other linear equation.

   Step 3 : Solve this, and you have the x -coordinate of the intersection.

   Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.

Answers

owes more than 1425
owe>1425

owed musbe be equal to how much he paid back

paid back 210

and 153 per month is paid back (represent number of months by x)
so
owe=210+152x

210+153x>1425
153x+210>1425
