Factor out 2x squared minus 98 completely

Answers

Answer:

2(x+7)(x-7)

Step-by-step explanation:

1. In 2x^2-98, there is a common factor of 2

2. The equation therefore becomes 2 (x^2 - 49)

3. We know that x^-49 is a difference of two squares and can therefore be factored into (x+7)(x-7)

4. Therefore the fully factored answer is 2(x+7)(x-7)

A line passes through the point (2,3) and has a slope of -2. Which is the equation of the line in point-slope form?

Answers

Answer:

7-2x=y

Step-by-step explanation:

When a point passes through a line it satisfies its equation

(X-x0 )m= y-y0

Slope = m = -2

(X-2 )(-2)=y-3

4-2x=y-3

7-2x=y

Answer:

-4x+5

Step-by-step explanation:

-(4x-2) change sign of each in parenthesis so they are now -4+2

now you have -4x+2+3 add like terms

now you have -4x+5

Distribute

[tex]\sf \longmapsto−4x+2+3[/tex]

Combine like terms

[tex]\sf \longmapsto−4x+2+3[/tex]

[tex]\sf \longmapsto(−4x)+(2+3)[/tex]

Don't shame I'm just trying to pass, my assignment's weigh 35% of my grade, right now my assignment percentage is 65%. My test which holds 45% of my grade is at 85% and my final is 20%, which I got a 90 on. If I take 7 0's in assignments, what would my grade be? Basically asking how many 0's under assignments can I basically take so I do not fail. Hope this makes sense

Answers

Answer:

Step-by-step explanation:

Let's start by weighing everything but the assignments. We'll get back to them momentarily.

You have 85% on 45% of your grade. That's 38.25

Your final weighs in at 20%. You have.           18

So your total so far is                                        56.25

Now that looks mighty low, but we haven't put in the assignments yet.  

So by the time you are finished you will have done 41 out of 48 assignments and that means you have done (41/48)*100 = 85.41 of the work. On these assignments that you have done, you averaged 65%

So your assignment mark will be 0.65 * 85.41 = 55.52

The weighted average = 0.35

The mark you will get is 0.35 * 55.52 = 19.32

So your final grade will be                      56.25  

Grade                                                        75.57

Currently James has $600 in his bank account, while Lisa has $500 in hers.

Every Friday afternoon James withdraws $15. At the same time Lisa withdraws $12 knowing that she can't spend as much as James.

Will their account balances ever be equal? If they are ever equal, how many weeks will it take?

Answers

Answer:

Their account balances will never be equal.

Step-by-step explanation:

I basically ran the math. 500 minus 12 times anything from 1-40 cannot equal 600 minus 15 times anything from 1-40. When we come to 600 - (15*40) we get zero.

i have to find the mean and range of this data set and show work.
data set: 49,50,52,58,61,63,66,67,67,68

Answers

Answer:

61 is the mean and the range is 19

Step-by-step explanation:

trust

Mean = [tex]60.1[/tex] and Range = [tex]19[/tex]  for the given set of data.

What is Mean?

"Mean is the average set of all the given values."

What is Range?

"Range is the difference between highest and the lowest value."

Formula

Mean = [tex]\frac{Sum of all the observations}{Total number of observations}[/tex]

Therefore, Mean = [tex]\frac{49 + 50 +52 +58 +61 +63 +66 +67 +67 +68}{10}[/tex]

                            = [tex]\frac{601}{10}[/tex]

                            = [tex]60.1[/tex]

Range = Max (x) - Min (x)

            =  [tex]68 - 49[/tex]

            = [tex]19[/tex]

Hence, the Mean = [tex]60.1[/tex] and Range = [tex]19[/tex] for the given data set.

Step-by-step explanation:

The pictures says RP = RQ,

so:

3x - 0.4 = x + 1.4

this you can simplify to:

x = 0.9

Then fill x in:

RP = 3*0.9 - 0.4 = 2.3

PQ = 0.9 + 0.1 = 1.0

RQ = 2.3

A. Identity Property
B. Commutative Property
C. Associative Property
D. Distributive Property

Answers

Answer:

associative property

Step-by-step explanation:

identity property is when you multiply one by any number and get the number you multiplied by. for example, 1x3=3; 1x7=7. Commutative property has to do with the order of multiplication being rearranged.  and distributive property multiplies a number outside the parentheses into the numbers inside. all that's left is the associative property which indicates that addition can be rearranged and still get the same answer. hope this helps :)
