The sum of degrees in a triangle is 180, so we have:

3x+100+x-4=180

add 4 on both sides

3x+100+x=184

subtract 100 on both sides

3x+x=84

Combine like terms

4x=84

P=a+b+c/3 solve for b

Answers

Answer:

3P= 3a+3b+c

3b=3a+c-3P

b= (3a+c-3P)/3

b= (3a)/3+c/3-(3P)/3

b= a+c/3-P

Step-by-step explanation:

let the expression with b be on one side of the equation while you send the other expressions to the other side of the equation.

now, divide through the equation with the coefficient of b which is 3.

simplify the equation by making b the subject of the equation

Find the equation of the circle centered at $(1,-4)$ with radius 3.

Write your equation in the form "$(x - h)^2 + (y - k)^2 = r^2$".

Answers

Answer:

[tex](x-1)^2+(y+4)^2=9[/tex]

Step-by-step explanation:

The equation of a circle is given by:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where (h, k) is the center and r is the radius.

The center of the circle is (1, -4).

And the radius is 3.

Substitute:

[tex](x-(1))^2+(y-(-4))^2=(3)^2[/tex]

Simplify. Thus, our equation is:

[tex](x-1)^2+(y+4)^2=9[/tex]

Answer: (x-1)^2+(y+4)^2=9

Use the graph to write the explicit rule of the arithmetic sequence

Answers

Answer:

It would be b.

Step-by-step explanation:

Plug in the numbers and try it out yourself. I did it and got b

The explicit rule of the arithmetic sequence is fₙ = 3 + 2(n-1) which is correct option(B).

What is arithmetic sequence?

An arithmetic  sequence is defined as an arrangement of numbers which is particular order.

What is graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

According to the graph, we get the sequence

3, 5, 7, 9, ...

Here,

a₁ = 3 is the first element.

An arithmetic sequence has a constant difference 'd' and is defined by  

fₙ = a₁ + (n-1)d

computing the differences of all the adjacent terms

5 - 3 = 2, 7 - 5 = 2, 9 - 7 = 2

The difference between all the adjacent terms is the same and equal to

d =2

substituting a₁ = 3 and d = -2 in the nth term of the sequence

fₙ = a₁ + d(n-1)

fₙ = 3 + 2(n-1)

Hence, the explicit rule of the arithmetic sequence is fₙ = 3 + 2(n-1).

Ruchi travelled 149 cm 415 in a week How much distance did she travel in a day​

Answers

Answer:

171.85 cm

Step-by-step explanation:

Given data

We are given that the distance = 149 cm 415in

Let us mark the units uniform by converting inches to cm

1 inches = 2.54cm

415 inches= x cm

cross multiply

x= 415*2.54

x= 1054.1 cm

Hence the total distance in cm is 1054.1+149= 1203cm

If in 7 days he travels 1203cm

in 1 day he will travel x cm

cross multiply

7x= 1203

divide both sides by 7

x= 1203/7

x= 171.85 cm

pablo will rent a car for the weekend. he can choose one of two plans. the first plan has an initial fee of $55.96 with additional costs of $0.12 per mile driven. the second plane has an initial fee of $63.96 and costs an additional $0.08 per mile driven. how many miles does pablo drive to make the miles the same?

Answers

Answer:

200 miles

Step-by-step explanation:

First, set up the equations.

plan 1: initial fee of $55.96, $0.12 per mile

y = 0.12x + 55.96

plan 2: initial fee of $63.96, $0.08 per mile

y = 0.08x + 63.96

We want to know at what distance will the cost be the same. So, set the equations equal to each other.

0.12x + 55.96 = 0.08x + 63.96

Combine the variables.

0.04x + 55.96 = 63.96

Combine the constants.

0.04x = 8

Divide by 0.04 to isolate x.

x = 200 miles

Check by plugging x back into each equation.

y = 0.12(200) + 55.96

y = 24 + 55.96

y = $79.96

y = 0.08(200) + 63.96

y = 16 + 63.96

y = $79.96

You are correct!

Y=2x+5 is correct in y intercept form. ^this one is the most common^

Y-3=2•(x+1) is correct in point slope form.

Use the point slope formula in which the point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
