Answer:

It is x > -5

Step-by-step explanation:

Equation: -3x + 8 < 23

First, we have to move the constant to the other side. By moving it to the other side, the sign also changes becoming -3x < 23 - 8.

Now we simplify: 23 - 8 becomes 15

New equation: -3x < 15

Finally, we want the X by itself, and to do that, we must divide -3 to both sides. Keep in mind that when we multiply or divide, the sign '<' also changes.

[tex]\frac{-3x}{-3}[/tex]<[tex]\frac{15}{-3}[/tex] = x > -5

It costs $20.50 to enter an amusement park and $0.25 to ride a ride. You have $21.50. Write an equation that represents the number r of rides you can ride.

Answers

Answer:

4 rides

Step-by-step explanation:

Total amount = $21.50

Entry charge = $20.50

Amount left = $21.50 - 20.50 = $1

Number of rides

[tex]r = \frac{1}{0.25} = \frac{100}{25} = 4 \\ [/tex]

Another way:

[tex] 0.25\:r + 20.50 = 21.50\\

0.25\:r = 21.50 - 20.50\\

0.25\:r = 1\\

r = \frac{1}{0.25}\\

r = \frac{100}{25}\\

r = 4\\[/tex]

A. 4
B. 2/3

Answers

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x - 3y = 12 ( subtract 2x from both sides )

- 3y = - 2x + 12 ( divide all terms by - 3 )

y = [tex]\frac{2}{3}[/tex] x - 4 ← in slope- intercept form

with slope m = [tex]\frac{2}{3}[/tex] and y- intercept c = - 4

g of x is greater than or equal to negative one half times x minus 5

Answers

Answer:

B) f(x) ≥ 3x + 4

g of x is less than or equal to negative one half times x minus 5

Step-by-step explanation:

From the above graph,  

If point B is the solution of the system of inequalities, then point B must satisfies both inequalities  

We can see from the graph that

Point B is located above (≥) the boundary line for f(x) and is also below (≤) the boundary line for g(x).

So we can say,

Point b satisfies the inequalities

Therefore,  

The system is  

 f(x) ≥ (3x+4)

 g(x) ≤ (-1/2x -5)

A 17-foot ladder is leaning on a tree. The bottom of the ladder on on the ground at a distance of 8 feet from the base of the tree. The base of the tree and the ground form a right angle as shown.


[ not drawn to scale ]

What is the distance, in feet, between the ground and the top of the ladder?

Answers

Answer:

15 feet

Step-by-step explanation:

Since, it's a right triangle, we will use the Pythagorean theorem formula:

[tex]a^2+b^2=c^2[/tex]

a and b are the straight sides and c is the ladder (hypotenuse).

[tex](8)^2+b^2=(17)^2[/tex]

Solve for [tex]x[/tex]:

[tex]64+b^2=289[/tex]

[tex]b^2=225[/tex]

[tex]\sqrt{b^2} =\sqrt{225}[/tex]

[tex]b=15[/tex]

The distance between the ground and the top of the ladder is 25 feet.

what is Pythagoras Theorem?

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.

Given:

Hypotenuse= 17 foot

Base = 8 feet

Now, using pythagoras theorem

H² = P² + B²

17² = P² + 8²

289 - 64 = P²

P= √225

P= 25 foot

Hence, the distance between the ground and the top of the ladder is 25 feet.

Determine whether or not the equations represent a direct variation . Sort the equations into the appropiate category.

Answers

Answer:

Direct variation: y = 3x, y = (2/7)x, and -0.5x = y

Not direct variation: x = -1, y = 2.2x + 7, and y = 4

Step-by-step explanation:

We know that the equation for direct variation is y = k · x, where you can fill in for k whatever number you want.

So, let’s figure this out by looking at the equations.

Equation 1: y = 3x

We know this is a direct variation equation because it all fits together and the 3 is a substitute for the variable, k.

Equation 2: x = -1

This is not an example of direct variation because:

1) the variable by itself on one side is x, when it is supposed to be y

2) there is only one number, -1, when instead it should say, -1x.

Equation 3: y= (2/7)x

This is an example of direct variation because the 2/7 is filling in for the k, and everything else matched the direct variation equation.

Equation 4: -0.5x = y

Since it doesn’t matter on which side y is, let’s just turn the equation around to make it simpler.

Now we have:

y = -0.5x

This makes sense because we have everything a direct variation equation needs to have plus the -0.5 substituting in for the k.

Equation 5: y = 2.2x + 7

This is also not an example of direct variation because although it has practically everything that an equation with direct variation has to have, it has that extra 7 there that ruins the equation.

Equation 6: y = 4

This is not an example of direct variation because there is no variable x in here! We have a k, but not an x!

Hope this helps! :)

The equations represent Direct variation are y = 3x, y = (2/7)x, and -0.5x = y

The equations represent Not direct variation: x = -1, y = 2.2x + 7, and y = 4

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

We know that the equation for direct variation can be written as;

y = kx,  

Equation 1; y = 3x

This is a direct variation equation because the 3 is a correct value for the variable, k.

Equation 2: x = -1

This is not an example of direct variation because the variable by itself on one side is x, when it is supposed to be y at that place.

Equation 3: y= (2/7)x

This is direct variation because the 2/7 is filling in for the k.

Equation 4: -0.5x = y

Since it doesn’t matter on which side y is, then just turn the equation around to make it simpler.

Now we have;

y = -0.5x

This is a direct variation equation that needs to have plus the -0.5 substituting in for the k.

Equation 5: y = 2.2x + 7

This is also a direct variation because although it has practically everything that an equation with direct variation has to have, it has that extra 7 there that ruins the equation.

Equation 6: y = 4

This is not an example of direct variation because there is no variable x. We have a k, but not an x!

0=83x+9

-83x=-0+9

-83x=9

x=9/-83

x=-0.1

Answer:

x = -27/8

Step-by-step explanation:

y = [tex]\frac{8}{3} x + 9[/tex]

to find x intercept let y = 0 then solve for x

0 = [tex]\frac{8}{3} x + 9[/tex]

-9 = [tex]\frac{8}{3} x[/tex]

divide both sides by 3

What is the equation of the line that has a slope of 3 and passes through the point (1, –2)?

Answers

Answer:

y = 3x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3 , thus

y = 3x + c ← is the partial equation

To find c substitute (1, - 2) into the partial equation

- 2 = 3 + c ⇒ c = - 2 - 3 = - 5

y = 3x - 5 ← equation of line
