The shifting of graph depends on value of b.

[tex]y = mx + b[/tex]

If b > 0, the graph shifts up.

If b = 0, the graph passes origin point.

If b < 0, the graph shifts down.

The only thing that's matter if the graph shifts up or down is about if the value of b is in negative or positive.

Why do the roots of a quadratic equation have the opposite sign of the factors of a quadratic equation

Answers

Answer:

To find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.

Step-by-step explanation:

Consider the provided information.

Roots of the equation is x-intercepts or zeros of the given equation.

So, By definition, the value of The y-coordinate is zero for points situated on the x-axis.

Thus, we can find the roots of a quadratic function, by putting f (x) = 0.

Now, let (x-a)(x-b) is the factor of any quadratic equation.

To find the roots of the quadratic function we will put our factor equal to 0.

[tex](x-a)(x-b)=0[/tex]

Now by the zero product property either x-a=0 or x-b=0

[tex]x-a=0[/tex] then [tex]x=a[/tex]

or

[tex]x-b=0[/tex]  then [tex]x=b[/tex]

So, we can say that to find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.

Leah is going to wrap the first box with wrapping paper. She measures the bottom of her box exactly to help her determine how much wrapping paper to use. The area of the bottom of the box is 36 1/8 square inches. Its width is 8 1/2 inches. What is the length of the bottom of the box?

Answers

Answer:

4.25 is the answer or 4 1/4

the width 8 1/2 inches and the area is 36 1/8. therefore we have to do 36 1/8 divided by 8 1/2 to get 4 1/4 as the side length

If (3a + 3b + 1) (3a + 3b - 1) = 80, then what is a + b?

Answers

Answer: a + b = 3 -        maybe

Step-by-step explanation:

( 3a + 3b + 1 )( 3a + 3b - 1 ) = 80

Expand

9a² + 9ab - 3a + 9ab + 9b² - 3b + 3a + 3b - 1 = 80

Simplify

9a² + 9b² + 18ab - 1 = 80

move the 1 over

9a² + 9b² + 18ab = 81

divide by 9

a² + b² + 2ab = 9

not really sure after this part

move the 2ab over

a² + b² = 9 - 2ab

square root both sides

a + b =  

simplify

a + b = 3 -

-4x - y = -17

5x = -15

Divide both sides by 5

x = -3

9x + y = 2

Substitute -3 for x

9 (-3) + y = 2

Find angle x and y. Please show step by step process.

Answers

Answer:

x = 60, y = 25

Step-by-step explanation:

Δ ABC has 3 congruent sides and is equiangular, thus

the 3 angles are congruent, all 60°

x = 60

∠ ABC and ∠ CBD are adjacent and supplementary, sum to 180° , then

∠ CBD = 180° - 60° = 120°, so

y = 180 - (120 + 35) = 180 - 155 ← sum of angles in triangle

y = 25
