Complete the statements below that show y = x2 + 2x - 1 being converted to vertex form.

Form a perfect-square trinomial.
y = x2 + 2x +
− 1−

Answers

We want to complete the steps to convert the given quadratic equation into vertex form.

Eventually we will get:

y = (x + 1)^2 - 2

Vertex form of a quadratic equation.

For a quadratic equation with the vertex (h, k), the vertex form is:

y = a*(x - h)^2 + k

Here we start with:

y = x^2 + 2x - 1

1) First, we complete the perfect-square trinomial, we need to add and subtract 1 to get that:

y = x^2 + 2x - 1 + 1 - 1

2) Now we rewrite the equation to be able of completing squares:

y = (x^2 + 2x + 1) - 1 - 1

y = (x^2 + 2x + 1) - 2

3) Now we complete squares

y = (x + 1)^2 - 2

And this is the equation in vertex form, where you can see that the vertex is the point (-1, - 2)

how do you differentiate linear equation from those equatipn which are not linear?​

Answers

Answer:

the x

Step-by-step explanation:

Looking at the x in an equation can reveal its shape. A linear graph can look like y=x, y=mx, y=mx+b (m being any number).

When you look at graphs that aren't linear, the x doesn't stand alone in the equation.

Parabolas have a y=x^2 equation. Cubic graphs are y=x^3. They have something attached to the x.

To see all the different kinds of equations and what their graphs look like you can search up "parent functions" and all the basic formulas show up.

Kenny had a total of 140 minutes to read, do homework, and play video games.
He spent x minutes reading.
He spent 2(x+5) minutes doing homework
He spent 25 minutes playing video games
How many minutes did Kenny spend reading
Help fast Please

Answers

Answer: 35minutes

Step-by-step explanation:

Minutes spent reading = x

Minutes spent doing homework =2(x+5) = 2x + 10

Minutes spent playing video games = 25minutes

Total minutes used = 140 minutes

x + 2x + 10 + 25 = 140

3x + 35 = 140

3x = 140 - 35

3x = 105

x = 105/3

x = 35 minutes

Which expression is equivalent to 32−−√−3x2–√+38–√?

Answers

Answer:

8

Step-by-step explanation:

The indices question is not properly written. Find the correct expression in the attachment

[tex]-32^{\frac{3}{5} }[/tex] [tex]= (\sqrt[5]{-32})^3[/tex]

for [tex]\sqrt[5]{-32}[/tex]

we need a value to multiply 5 times that will give us -32;

[tex]\sqrt[5]{-32} = -2[/tex]

substitute the answer in the original expression

[tex]= (\sqrt[5]{-32})^3\\= 2^3[/tex]

Evaluate the resulting indices

[tex]2^3 = 8\\[/tex]

Hence the expression [tex]-32^{\frac{3}{5} }[/tex] is equivalent to 8

Step-by-step explanation:

10abc - 2d = 3d

Add 2d to each side

10abc - 2d+2d = 3d+2d

10 abc = 5d

Divide each side by 10ac

10 abc/ (10ac) = 5d/10ac

b = d/(2ac)

Tradition is a guide, and not a jailer. (W. Somerset Maugham) What do you think this quote means? Thank youu! Here is a table of the average distance and the variation in the distance for the five innermost planets in our solar system: Average Distance and Variation Planet Name Average Distance Variation Mercury 36.0 million miles 7.39 million miles Venus 67.2 million miles 0.43 million miles Earth 93.0 million miles 1.55 million miles Mars 142 million miles 13.2 million miles Jupiter 484 million miles 23.2 million miles "Average distance" means the mean distance that planet is from the sun over the course of its orbit, and "variation" means how far it varies from that mean. For example, if a planet had an average distance of 5 miles and a variation of one mile, it would have distances between 4 and 6 miles at different times. a) Write and solve an inequality to represent the range of distances that can occur between the Sun and one of the planets from the table (your choice).
