Write a quadratic equation that has 2 and 8 as solutions.
Find the equation with 1 as the coefficient of the quadratic term.

Answers

Answer:

[tex]x^2-10x+16[/tex]

Step-by-step explanation:

The way I would find the equation is by finding the factored form of the equation form. That equation would be (x-2)(x-8). These are correct because if you set both of these equal to zero, your x-values will be equal to 2 and 8.

x-2=0

x=2

x-8=0

x=8

If you want the standard form of the equation,  all you have to do is multiply it out.

[tex](x-2)(x-8)\\x(x-8)-2(x-8)\\x^2-8x-2x+16\\x^2-10x+16[/tex]

Answer:

because of parallel lines it's 63

Given that < h (interior) and < k (exterior) are on the same side of the transversal, they are corresponding angles with the same measure.

Given that m < k = 63°, then m < h must also be 63°.

Therefore, the correct answer is 63°.

Are the two lines parallel, perpendicular,
or neither?
y = 3x -4 and 3x +9y = 18

Answers

they are parallel. if the slopes are the same and the y intercept is different they are parallel

Prerequisites :-

1) The product of slope of two perpendicular lines is-1 .

2) The slope of two parallel lines is same .

Given two lines to us are ,

[tex] y = 3x - 4 [/tex]

This line is in slope intercept form which is [tex] y = mx + c [/tex] . Comparing to which we get ,

[tex] m_1 = 3 [/tex]

Again , the second line given to us is ,

[tex] 3x + 9y = 18 [/tex]

Convert it into slope intercept form , we have ,

[tex]\implies 3( x + 3y ) = 18 [/tex]

Divide both sides by 3 ,

[tex]\implies x + 3y = 6 [/tex]

Solve for y ,

[tex]\implies y = \dfrac{-x}{3} + 2 [/tex]

On comparing to the slope intercept form ,

[tex] m_2 = \dfrac{-1}{3}[/tex]

And the product both the slopes is ,

[tex]\implies m_1 \times m_2 = \dfrac{-1}{3}\times 3 =\boxed{\red{-1}}[/tex]

Hence the given two lines are perpendicular .

Answer:

angles 2 and 10 are corresponding Angles while angles 6 and 11 are alternate Angles

Answer:

1. False   Same side exterior angles refers to same side transversal An example; opposite ends both same side of transversal. see 2nd attachment.

2. False   interior alternate are both interior alternate on a Z 3 would be alternate with 6 as both are within the z and diagonally opposite at ends of the z shape.

3. True  (yes both same sides of transversal one is left of parallel line the other is left of the next parallel.

4. False ( 12 is only alternate with 1 as alternate is within the z shape as exterior and opposite sides of the transversal)

Step-by-step explanation:

Alternate Interior Angles – Alternate interior angles are the pair of angles on the inner side of the two parallel lines but on the opposite side of the transversal. Alternate Exterior Angles – Alternate exterior angles are the pair of angles on the outer side of the two parallel lines but on the opposite side of the transversal

Same side exterior angles - are seen on the blue spots on the 2nd diagram transversal

hannah and mallory are selling boxes of cookies for a school fundraiser. each box costs the same amount. hannah sells 14 boxes. mallory sells 22 boxes. mallory's neighbor makes a $6 donation without buying any cookies. together, hannah and mallory raise $141. write ans solve an equation to find out how much each box of cookies costs. how much does hannah raise? how much does mallory raise?

Answers

The cost per box of cookies is $3.75

The total amount Hannah raised from the sales of cookies is $52.50

The total amount Mallory raised from the sales of cookies and donations is $88.50

In order to determine the cost per box of cookies, take the following steps:

The first step is to determine the total sum of the boxes sold by Hannah and Mallory

Sum of the boxes sold = 14 + 22 = 36 boxes

36 boxes were sold by Hannah and Mallory

The second step is to determine the total cost of the 36 boxes sold.

Total cost of 36 boxes = total amount raised - donation

$141 - $6 = $135

The third step is to determine the total cost of each box

cost of one box = total cost of 36 boxes / total number of boxes

135 / 36 = $3.75

The total amount Hannah raised = cost per box x number of boxes she sold

14 x $3.75 = $52.50

The total amount Mallory raised = amount raised from the sale of cookies + donation

amount raised from sales = cost per box x number of boxes she sold

22 x $3.75 = $82.50

Total amount = $82.50 + $6 = $88.50
