Answer:

The middle two expressions shown are not polynomials

Step-by-step explanation:

Polynomial terms have positive integer exponents on any variables. A 2/3 power is not an integer exponent. Division by y is equivalent to an exponent of -1, which is not a positive integer.

A parabola has an x-intercept of -1, a y-intercept of -3, and a minimum of -4 at x = 1.

torisob [31]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

$y=a(x-h)^{2}+k$

where

a is a coefficient

(h,k) is the vertex

In this problem we have

(h,k)=(1,-4)

substitute

$y=a(x-1)^{2}-4$

we have

An x-intercept of (-1,0)

substitute and solve for a

$0=a(-1-1)^{2}-4$

$0=4a-4$

$4a=4$

$a=1$

The equation is

$y=(x-1)^{2}-4$

<u><em>Verify the y-intercept</em></u>

For x=0

$y=(0-1)^{2}-4$

$y=-3$

The y-intercept is the point (0,-3) -----> is correct

using a graphing tool

Y= 2/3x -1 y= -x + 4

blondinia [14]

Answer:

$x=3\\y=1$

Step-by-step explanation:

To solve the system of equations you must apply the proccedure shown below:

- Make both equations equal to each other.

- Solve for x.

Then:

$\frac{2}{3}x-1=-x+4\\\\\frac{2}{3}x+x=4+1\\\\\frac{5}{3}x=5\\5x=5*3\\x=\frac{15}{5}\\\\x=3$

- Substitute the value of x obtained into any on the original equations to find y:

$y=-3+4\\y=1$

For the two figures to be similar, the missing length must be 30.

<h3 /><h3>What is the missing length?</h3>

For the two figures to be similar, the dimension of each figures must be proportional to each other.

Let the missing length be x.

Hence,

x/25 = 24/20

We cross multiply

x × 20 = 24 × 25

x × 20 = 600

x = 600/20

x = 30

Therefore, for the two figures to be similar, the missing length must be 30.
