Mathematics
1 answer:
zalisa [80]3 years ago

<span>Proof by contradiction is simply a specific way to form indirect proof that will show the validity of someone's argument or position. It begins by someone assuming the opposite of what they propose is true then goes on to prove that the improper assumption simply leads to a contradiction.</span>

HELP ILL GIVE YOU BRAINLIEST
Alex Ar [27]

Answer:

1. Distributive Property

2. Addition Property of Equality

3. Multiplicative Property of Equality

Step-by-step explanation:

1. The 3 is multiplied by each number in the parenthesis

3*10=30

3*2=6

So 3*(10-2x)=30-6x

2. The 30 is subtracted from both sides

30-6x-30 = -6x

6-30 = -24

30-6x-30=6-30

So -6x=-24

3. The -6 is divided from both sides

-6x/-6 = x

-24/-6 = 4

-6x/-6 = -24/-6

So x=4

Find the slope of the line through these pair of points.<br><br> (12,-18) (-15,-18)
zysi [14]
The slope, m, is given by the equation m = (y2-y1)/(x2-x1), where (x1, y1) and (x2, y2) are points on the graph. Thus:
m = (-18-(-18))/(-15-12)
= (-18+18)/-27
= 0/27 = 0
Therefor the slope is 0

Please help asap its due in one minute
kicyunya [14]
The first thing you would do is substitute the 10 in for 'w' and 535 in for 'c'. 
535 = 235 + 30(10)
535 = 185 + 35(10)
Then, you would just solve the equations.
535 = 235 + 30(10)
30(10) = 300
300 + 235 = 535 
So the first equation is true, and we know for a fact that Larry's Landscaping charges $535 for a spring cleaning and weekly yard maintenance for 10 weeks.
On to the next equation.
535 = 185 + 35(10)
35(10) = 350
185 + 350 = 535
So, the second equation is true also. And we also know for a fact that Joe's Landscaping charges $535 for a spring cleaning and weekly yard maintenance for 10 weeks. 
So, now that we know that they will end up charging the same amount of money for a spring cleaning and weekly yard maintenance, the only answer that fits that is C. The cost for lawn maintenance is the same, $535, for both landscaping companies after 10 weeks.
Hope this helps!

Which of the I-values satisfy the following inequality?
e-lub [12.9K]

Answer:

The answers are options A and B

First solve the inequality

7x < 21

Divide both sides by 7

That's

7x/7 < 21/7

x < 3

The values that satisfy the inequality are

1 and 2 since they are both less than 3

Hope this helps you.
