I need help solving (5-6x9+6)x9+3-85 I came up with -109. Is that right

Answers

Answer 1

Answer: Multiply −6 by 9 to get −54.(5−54+6)⋅9+3−85Subtract 54 from 5 to get −49.(−49+6)⋅9+3−85Add −49 and 6 to get −43.−43⋅9+3−85Multiply −43 by 9 to get −387.−387+3−85
Add −387 and 3 to get −384.−384−85Subtract 85 from −384 to get −469.−469

thats what i did to get -469. show your work for finding -109 and we can compare

Answer 2

Answer: So we have
(5-6x9+6)x9+3-85

So this is a oder of operation question, firstly you start with the brackets

(5-6x9+6)

B. Brackets
E. Exponents
D. Division
M. Multiplication
A. Addition
S. Subtraction

(5-6x9+6)

Multiplication first

6x9=54

Now we have
(5-56+6)

56+6=62

62-5=57

((57))

Now we have left

57x9+3-85
Start from multiplication

57x9=513

513+3= 516

516-85= 413

413

What is 3.75 in fraction form

Answers

3.75 in fraction form is 3 3/4 or 15/4

3.75
so it would be 3 and then you turn .75 into a fraction which would be 3/4

answer: 3 3/4

If you have a lot of Pythagorean triples memorized, then you'd probably know immediately, but if not, then you can use the Pythagorean Theorem to calculate each one:

A.: 7^2+9^2=49+81 which is not equal to 13^2, or 169

B.: 5^2+12^2=25+144 which is not equal to 14^2, or 196

C.: 8^2+15^2=64+225=17^2=289

D.: 9^2+12^2=81+144 which isn't equal to 14^2, or 196

Therefore, the correct answer is C.

so 2 real solutions
just write 2 factors and expand
(x-3)(x-4)=0
x^2-7x+12=0
discriminant is when you have b^2-4ac
so subsitute
ax^2+bx+c=0
a=1
b=-7
c=12
-7^2-4(1)(12)
49-48=1
discriminant=1

one real solution would be
(x-1)(x-1)=0
x^2-2x+1=0
discriminant=-2^2-4(1)(1)=4-4=0
discriminant=0

no real solutions has the discriminant less than zero
let's say that b=1 and c=20 and a=1
basically, we need a set of numbers where b^2 is less than 4acso

1^2-4(1)(20)=1-80=-79
then we subsitute
x^2+x+20=0

autumn used 0.675 of the battery life on her mp3 player. her brother borrowed it to play a game and used 0.2 of the total battery life. of her mp3 player shows the battery life that remains as a percentage, what does it showed after her brother is finished?

Answers

She starts out with the battery 100% full.
0.675 as a fraction is 67.5%
Subtract 67.5% from the initial amount.
100% - 67.5% = 32.5%
0.2 as a fraction is 20%
Subtract 20% from the amount left:
32.5% - 20% = 12.5%.She has 12.5% left.

Answers

Lines are in the form y=mx+b, where m is the slope and b is the y-intercept. This line is thus y=9/4x-14, so C is correct. Multiplying by four, we get 4y=9x-56. Adding 56 and subtracting 4y, we see that 9x-4y=56, and multiplying by -1, we get 4y-9x=-56, so A is also correct. At this point, it is clear that B and D are incorrect, so A and C only are correct.

You know that you can spot the slope and intercept right away
IF you 'solve' the equation for 'y'. Then you'll have

y = (slope) x + (intercept) .

So for choices 'A' and 'B', you have to massage the equation
into the standard form, and then just look at it and see whether
the slope is 9/4 and the intercept is -14.

A).         -9x + 4y =   -56

Add 9x to each side:    4y = 9x - 56

Divide each side by 4 :   y = 9/4 x - 14    <== Yes ! Good one.

B). 9x + 4y = 56

Subtract 9x from each side:   4y = -9x   + 56

Divide each side by 4 :       y = -9/4 + 14 <= no, signs are wrong

C). Yes. Slope is 9/4 and intercept is -14 .

D). No. Slope is 9/4 alright, but intercept is +14, not -14 .
