What is the slope of this line?

Answers

Answer:

A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .

A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .

If a line is horizontal the slope is zero. This is a constant function.

If a line is vertical the slope is undefined (see below).

Solve the following system of equations.
x-3y=17
x+7y=-23
x=
y=

Answers

Answer:

-4y=40

y=-10

x-3(-10)=17

x-30=17

x=17+30

x=47

Step-by-step explanation:

Answer:

x= 5

y= -4

Step-by-step explanation:

x= 17+3y so you substitute what you got for x in so

17 +3y +7y = -23

10y=-40

y=-4 now you put -4 in for y in the first equation

x = 17 + (3 times -4)

x = 17 - 12

x=5

42 = y + 15 whats y? y == __

Answers

y=27 because 42-15 is 27

Solution

[tex]y=27[/tex]

Step-by-step explanation:

Subtract [tex]15[/tex] from both sides of the equation:

[tex]42=y+15[/tex]

[tex]42[/tex][tex]-15=y+15[/tex][tex]-15[/tex]

Simplify:

Subtract the numbers:

[tex]42-15=y+15-15[/tex]

[tex]27=y+15-15[/tex]

Subtract the numbers:

[tex]27=y+15[/tex][tex]-15[/tex]

[tex]27=y[/tex]

Move the variable to the left:

[tex]27=y[/tex]

[tex]y=27[/tex]

[tex]y=27[/tex]

A group of friends wants to go to the amusement park. They have no more than $235 to spend on parking and admission. Parking is $7, and tickets cost $28.50 per person, including tax. Write and solve an inequality which can be used to determine pp, the number of people who can go to the amusement park.

Answers

228/28.50= 8 that should be right!

The solution of the inequality for the number of people (p) who can go to the amusement park will be;

⇒ p < 8

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

They have no more than $235 to spend on parking and admission.

And, Parking is $7, and tickets cost $28.50 per person, including tax.

Now,

Let the number of people who can go to the amusement park = p

So, We can formulate;

⇒ 28.50p + 7 < 235

Solve for p as;

⇒ 28.50p < 235 - 7

⇒ 28.50p < 228

⇒ p < 228/28.50

⇒ p < 8

Thus, The solution of the inequality for the number of people (p) who can go to the amusement park is;

⇒ p < 8
