How do I put the slope and y-intercept on the graph

So as you can see, -3 is the y-intercept. You would make a point on (-3,0) first. Then from the point, you would go up 1 and go right 2 because the slope is a positive 1/2 slope.

In order to graph an equation, you must first need to have a y-intercept to know where your starting point is.

vazorg [7]

Answer:

Answer: 119.32

Step-by-step explanation:

To find circumference you must do diameter × pi or radius × 2 × pi sense we are given the diameter its easy peasy so we can just do 38 × pi so... 38 × 3.14 = 119.32 so 119.32 is the cirmcumfrence Hope that helps!!

X+y=5<br> 2x - y = 1<br><br> Need help

erma4kov [3.2K]

Answer:

y = 3

x = 2

Step-by-step explanation:

x+y=5 == -2x - 2y = -10

2x-y = 1 == 2x - y = 1 +

-------------------

-3y = -9

<u>y = 3</u>

x + y = 5

x + 3 = 5

<u>x = 2</u>

Please help me if you can ‼️

Karolina [17]

Answer:

$y=14.5x+5$

Step-by-step explanation:

Let

x ----> the number of tickets

y ----> the price of tickets

we have the ordered pairs

(4,63) and (6,92)

step 1

<em>Find the slope of the linear equation</em>

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{92-63}{6-4}$

$m=\frac{29}{2}=\$14.5\ per\ ticket$

step 2

Find the y-intercept or initial value of the linear equation

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope b is the y-intercept

we have

$m=14.5$

$point\ (4,63)$

substitute

$63=14.5(4)+b$

solve for b

$b=63-14.5(4)$

$b=\$5$

In this context the y-intercept is a one charge fee for the ticket service

The equation is equal to

$y=14.5x+5$

A set W of strings of symbols is defined recursively by 1. a, b, and c belong to W. 2. If x belongs to W, so does a(x)c. Which o

Vadim26 [7]

Answer:

a. a(b)c

b. a(a(b)c)c

d. a(a(a(a)c)c)c

Step-by-step explanation:

We are given the following in the question:

$a,b,c \in W\\\text{If } x \in W \Rightarrow a(x)c \in W$

a. a(b)c

It is given b belongs to W.

$b \in W\\\Rightarrow a(b)c \in W$

b. a(a(b)c)c

$a(b)c \in W\\\Rightarrow a(a(b)c)c \in W$

c. a(abc)c

a(abc)c does not belong to W because we cannot find x in W such that a(abc)c belongs to W.

d. a(a(a(a)c)c)c

$a \in W\\\Rightarrow a(a)c \in W\\\Rightarrow a(a(a)c)c \in W\\\Rightarrow a(a(a(a)c)c)c$

e. a(aacc)c

a(aacc)c does not belong to W because we cannot find x in W such that a(aacc)c belongs to W.
