Answer:

y = -3 and y = -3

or y = -3 with a multiplicity of 2

Step-by-step explanation:

(y+4)^2-2(y+4)+1

If you want to factor this, heres what you do:

(y+4)(y+4)-2(y+4)+1

y^2+8y+16-2y-8+1

y^2+6y+9

Then factor:

(y+3)(y+3)

(y+3)^2

The value of y:

y + 3 = 0 and y + 3 = 0

y = -3 and y = -3

or y = -3 with a multiplicity of 2

IrinaVladis [17]

Answer:

14 days

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

25n+100=450

Step 2: Subtract 100 from both sides.

25n+100−100=450−100

25n=350

Step 3: Divide both sides by 25.

25n/25 =350/25

n=14

Label each statement as true or false regarding the zeros/roots of a quadratic function. The roots zeros of a quadratic function
ikadub [295]

Answer:

True, false, true, true.

Step-by-step explanation:

The roots zeros of a quadratic function are the same as the factors of the quadratic function. This is true because your roots are your factors—>(x-3) is a factor, x=3 is the root.

The roots zeros are the spots where the quadratic function intersects with the y-axis. No! Those are called y-intercepts!

The roots zeros are the spots where the quadratic function intersects with the x-axis. True. X-intercepts are your solutions. (x-3) graphed would the (3,0). That’s a solution.

There are not always two roots/zeros of a quadratic function,​ True. No solution would be when your quadratic doesn’t intersect the x-axis. One solution would be when your vertex would be on the x-axis. Two solutions is when your quadratic intersects the x-axis twice. Can there be infinite solutions? No. It’s either 0, 1, or 2 solutions.

Write a linear function that passes through (1,5) and (2,15)
Leokris [45]
Simple,

using \frac{y1-y2}{x1-x2} =m (slope)

find your slope...

\frac{5-15}{1-2} = \frac{-10}{-1}=10

thus, 10=m (slope)

Now, using y=mx+b to find your equation, plug in what you know...

Use any of the 2 coordinates.. (1,5)

5= 10(1)+b

5=10+b
-10 -10

-5=b

Thus, the equation to your line is...

y=10x-5.

What is 2 plus 2 minus 17
nataly862011 [7]

<em>The result is -13</em>

<h2>Explanation:</h2><h2 />

Here we have the following addition problem:

2+2-17

So let's solve this step by step:

Step 1. Perform two plus two.

2+2=4

So:

2+2-17=4-17

Step 2. Perform the subtraction.

Since the sign (-) accompanies 17 which is greater than 4, then we perform the subtraction and add the sign (-) to the result. So:

2+2-17=4-17=-13

<em>Finally, the result is -13</em>
