Evan earned $26 for 4 hours of babysitting.
What equation can be used to model his
total earnings y for babysitting x hours?
Then graph the equation on the coordinate
plane. What is the unit rate? How is that
represented on the graph?

Answers

$26 / 4 hours= $6.5/ hour

The equation y = 6.5x will represent the situation and the unit rate will be $6.5/hour.

How to plot a graph?

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given that,

Evan earned $26 for 4 hours of babysitting.

If total earnings y for babysitting x hours then,

y = (26/4)x ⇒ y = 6.5x will be the equation.

The unit rate of the function is y/x = $6.5/hour.

Hence "The equation y = 6.5x will represent the situation and the unit rate will be $6.5/hour".

the position of a deep sea probe is -2 3/4 fathoms relative to the sea level. after finishing taking data, it moves to -2 5/8 fathoms relative to sea level. which was deeper, the first mission, or the second. (i’m in modern high school which means i get collage questions, i only have 1 hour left to get this done, someone help!)

Answers

Answer:

The first mission

Step-by-step explanation:

The depth readings are

The first mission: - 2 3/4 fathomsThe second mission: - 2 5/8 fathoms

Comparing the readings

- 2 3/4 = - 2 6/8 and - 2 5/8

Absolute values compared

2 6/8 > 2 5/8

Indicating the greater value on the first mission

As per above, the first mission was deeper

-17 = -7c + 4

Answers

Answer: c = 3

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Subtract 4 from both sides.

-17 - 4 = -7c

Step 2: Simplify -17 - 4 to -21.

-21 = 7c

Step 3: Divide both sides by -7.

[tex]\frac{-21}{-7}[/tex] = c

Step 4: Two negatives make a positive.

[tex]\frac{21}{7}[/tex] = c

Step 5: Simplify [tex]\frac{21}{7}[/tex] to 3.

3 = c

Step 6: Switch sides.

c = 3

so for 4 yoga classes, it is $75

so for 8 yoga classes, it is $115

so for 12 yoga classes, it is $155

Step-by-step explanation:

So 35 is only a one-time payment and it is over so we just add 35, but $10 is the rate of change depending on how much yoga class you have been into so the equation will be y=10x+35

Explanation for 4 yoga classes: y=10(4)+35 which is 75

Explanation for 8 yoga classes: y=10(8)+35 which is 115

Explanation for 12 yoga classes: y=10(12)+35 which is 155

What is the slope between point A (-9, 4) and B ( 3, -2)
I NEED HELP ASAP

a)1/2
b)-1/2
c)2
d)-2
e)3/2

Answers

Slope can be calculated using the formula: m= [tex]\frac{y2 - y1}{x2 - x1}[/tex]

y1/x1 represents the first number in the bracket

y2/x2 represents the second number in the bracket

Calculation

m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

m =[tex]\frac{4 - (-2)}{(-9)-3}[/tex]

m= 6/-12

m= -0.5 or -1/2

Therefore, the answer is B.

Which statements below are TRUE about perpendicular lines? I. Perpendicular lines intersect II. Perpendicular lines create right angles III. Perpendicular lines are collinear IV. Perpendicular lines never intersect V. Perpendicular lines are coplanar

Answers

Answer:

Step-by-step explanation:

Two lines are perpendicular to each other if they both intersects and the two lines are inclined at angle 90°

Since they are inclined at 90° to each other, hence they create right angles.

The lines can also lines on the same plane to form a right angles. This are called coplanar lines.

From the above explanation, the following are true;

I) Perpendicular lines intersect

II) Perpendicular lines create right angles

V) Perpendicular lines are coplanar

They are not collinear because they can't lie on the same straight line. Collinear lines are known to lie on the same straight line.

select all values that make the equation true 2(x-8)=x+5x
x= -4
x= -16
x= -2
x= -0

Answers

Answer:

x = -4

Step-by-step explanation:

2(x-8)=x+5x

Combine like terms

2(x-8) = 6x

Divide by 2

2(x-8)/2 = 6x/2

x-8 = 3x

Subtract x from each side

x-8-x = 3x-x

-8 = 2x

Divide by 2

-8/2 = 2x/2

-4 =x

X=-4
2(x-8)=x+5x
2x-16=6x
Subtract 2 from each side
-16=4x
Divide both side by 4
-4=x

Hana rents a car for a day. Her car rental company charges $50 per day and $0.40 per mile. Peter rents a car from a different company that charges $70 per day and $0.30 per mile. How many miles do they have to drive before Hana and Peter pay the same price for the rental for the same number of miles?

Answers

50 + .4x = 70 + .3x

.4x = .3x + 20

.1x = 20

x = 200

Let x be the number of miles.

They have to drive 200 miles.

They will drive 200 miles before paying same amount.

Let the number of miles that they will drive together and pay the same amount be represented by x.

Since Hana's car rental company charges $50 per day and then $0.40 per mile, this can be represented as:

= 50 + (0.40 × x)

= 50 + 0.40x

Since Peter rents a car from a different company that charges $70 per day and then $0.30 per mile, this will be:

= 70 + (0.30 × x)

= 70 + 0.30x

Then we will equate both Hana's and Peter's equation together and this will be:

50 + 0.40x = 70 + 0.30x

Collect like terms

0.40x - 0.30x = 70 - 50

0.1x = 20

x = 20/0.1

x = 200

In conclusion, they will drive 200 miles before paying thesame amount

Given:

The point is rotated at 272 degrees clockwise.

To find:

The smallest positive counterclockwise rotation for the given clockwise rotation.

Step-by-step explanation:

Clockwise rotation = 272°

We need to subtract the given clockwise rotation from 360° to get the smallest positive counterclockwise rotation, because one complete circle is 360°.

Counterclockwise rotation = 360° - Clockwise rotation

= 360° - 272°

= 88°

Therefore, the smallest positive counterclockwise rotation is 88°.
