-3m-[2m+(5-m)]+7 explain how the simplified answer: 2-4m is correct

Mathematics
1 answer:
gulaghasi [49]3 years ago
4 0

Step-by-step explanation:

So what you can do is first get ride of the parentheses around 5-m so:

-3m - (2m + 5-m)+7

Then, you can simplify the numbers inside the parentheses, so:

-3m-(m+5) + 7

Then, you can get rid of the parentheses by distributing the - sign:

-3m-m-5+7

Next, just combine like terms:

-4m + 2 or 2-4m

In a linear functions, f(x)=mx+b, your y-intercept is b. So any function that is any number times x plus 3 is going to give you a y intercept of 3.

Is 14,48,50 a Pythagorean triplet <br> Step by step explanation please
Svetlanka [38]

Answer:

yes

Step-by-step explanation:

If the values are a Pythagorean triplet then the square of the largest value should equal the sum of the squares of the other 2

largest value = 50 ⇒ 50² = 2500

14² + 48² = 196 + 2304 = 2500

Since 50² = 14² + 48² then 14, 48, 50 are a Pythagorean triplet

-3 1/3 = 1/2g what does g =
sertanlavr [38]
The equation given in the question is
- 3 1/3 = 1/2g
- 10/3 = 1/2g
- (10 * 2g) = 1 * 3
- 20g = 3
- g = 3/20
g = - (3/20)
So the value of g that has been deduced is -(3/20). This is the easiest procedure to get to the solution of the question gives. Based on the above procedure, similar problems can be easily solved without any error or issue. I hope this solution has helped you.

If Oliver withdraws $285.10 from his savings account to make the purchase, how much would he have earned in interest on that amo
never [62]
Oliver withdraws an amount of $285.10 from his saving account

His saving account earns 1.8% annually

The interest Oliver could have earned in five months:

Monthly interest = Annual interest ÷ 12
Monthly interest = 1.8% ÷ 12
Monthly interest = 0.018 ÷ 12 = 3/2000

After five months = Principle × (1 + interest)ⁿ
After five months = 285.10 × (1 + 0.018)⁵
After five months = 311.70

Interest earned = 311.70 - 285.10 = $26.60

The terminal side of an angle θ in standard position passes through the point (3, 1). Calculate the exact values of the six trig
patriot [66]

Answer:

sin α = \frac{y}{r} = \frac{1}{\sqrt{10} }

cos α = \frac{x}{r} = \frac{3}{\sqrt{10} }

tan α = \frac{y}{x} = \frac{1}{3}

cot α = \frac{x}{y} = \frac{3}{1}

sec α = \frac{r}{x} = \frac{\sqrt{10} }{3}

csc α = \frac{r}{y} = \frac{\sqrt{10} }{1}

Step-by-step explanation:

If the point is given on the terminal side of an angle, then:

Calculate the distance between the point given and the origin:

r = \sqrt{x^2+y^2}

Here it is: \sqrt{3^2+1^2} = \sqrt{9+1} = \sqrt{10}

So we have:

x = 3

y = 1

r = \sqrt{10}

Now we can calculate all 6 trig, functions:

sin α = \frac{y}{r} = \frac{1}{\sqrt{10} }

cos α = \frac{x}{r} = \frac{3}{\sqrt{10} }

tan α = \frac{y}{x} = \frac{1}{3}

cot α = \frac{x}{y} = \frac{3}{1}

sec α = \frac{r}{x} = \frac{\sqrt{10} }{3}

csc α = \frac{r}{y} = \frac{\sqrt{10} }{1}
