please help! i would appreciate it!

Answer:

Step-by-step explanation:

let y be the total charges

given that the hour is h

and the cost for raw material is r

therefore

1. The first hour of service call = $60

2. For each additional hour= 25h

 3. 30% over the cost of the materials.= 30/100*r=0.3r

total charges

y=60+25h+0.3r

therefore the expression is

y=60+25h+0.3r

Answer:

The answer would be 'C'

Answer:

9x² - 42x + 49

Step-by-step explanation:

Given

(3x - 7)² = (3x - 7)(3x - 7)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(3x - 7) - 7(3x - 7) ← distribute both parenthesis

9x² - 21x - 21x + 49 ← collect like terms

= 9x² - 42x + 49

Answer:

Ok, so first, at the end of the equation, It says "+ 4" , right? So you put a point on positive 4 on the y-axis (the one that goes up and don, the vertical line.). Then, 2x means that's your slope, but since your graph only goes up to five, you gotta count down ward. So, go down from your point on the y-axis (4) twice and over to the LEFT (<--) once. Plot your point where you end up. then use a straightedge like a ruler, and connect your two points on the graph, and you have your line!

Step-by-step explanation:

The slopes of parallel lines are equal.

Since the slope of the 2nd Ave. line is horizontal, it has no slope.

This means that the new road should also have no slope.

Hope this helps.

The 2nd-eve line is horizontal then the slope of the line will be zero.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope of the line is defined as the ratio of the rise to the run.

Given that a city planner wants to build a road parallel to 2nd Ave. The 2nd eve has the horizontal line.

The slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 0 - 0 ) / ( -4 + 2 )

Slope = 0

Therefore, the 2nd-eve line is horizontal then the slope of the line will be zero.

Step-by-step explanation:

For number 3 you go rise over run. From the point on the y-axis you rise 3 and then run 4 to the x-axis if that makes any sense

1. please start to pay attention

1. an undefined slope is vertical

2. 90-70/15-3 = 20/12 = 10/6 = 5/3

3. 3/4 (rise over run)

4. slope: -1/5   y-intercept: 12

5. 1

6. y = 1/2x +b

   3 = 1/2(1) +b

   3 = 1/2+b

   subtract 1/2 from both sides

   2 1/2 = b

   y = 1/2x + 2 1/2

Answer:

C=50t+150

Step-by-step explanation:

From the information given, the equation will need to show that the total cost of the electrician services would be equal to 50 that is the hourly rate for the number of hours spent working plus the fixed fee:

Fixed fee=250-(50*2)=250-100=150

According to this, the equation would be:

C=50t+150, where C is the total cost of the electrician's services and t is the number of hours spent working.

Answer:

y = x+5

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

   = ( 7-3)/(2 - -2)

   ( 7-3)/(2+2)

   4/4

  1

Then slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 1*x+b

y = x+b

Substitute a point into the equation

7 = 2+b

7-2 =b

5=b

y = x+5

Work Shown:

8/3 = (6+2)/3

8/3 = 6/3 + 2/3

8/3 = 2 + 2/3

8/3 = 2 & 2/3

The whole part is 2. The fractional part is 2/3.

-----------

Another way you could do the problem is to use long division as shown in the diagram below.

The result of the long division is

8/3 = 2 remainder 2

The quotient 2 forms the whole part and the remainder is the numerator of the fractional part 2/3.

So that's another way to get 2 & 2/3

Same number on both dice ( in first throw) + Different numbers ,with an even sum (in second throw) + An odd sum(third throw) + An odd sum(fourth throw) + Different numbers ,with an even sum (in fifth throw)

From the given ,question Abbie, Chloe, and Xander are playing a dice game.

They are playing with two dices.

The game rules are;

Same number on both dice = +3

Different numbers, with an even sum = +1

An odd sum = -2

After five rounds, score of Chloe = +1

1 = 3 + 1 + (-2) + (-2) + 1

⇒ Same number on both dice ( in first throw) + Different numbers ,with an even sum (in second throw) + An odd sum(third throw) + An odd sum(fourth throw) + Different numbers ,with an even sum (in fifth throw)

If we alter the arrangements, In each case you will get sum as (+1), as integers satisfy both Commutativity and Associativity with respect to addition.

Answer: choice A

Step-by-step explanation:

The linear inequality represented by the graph  is y≥1/3x-1

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Let us find slope of line passing through points (0, -1) and (3, 0)

Slope = 0+1/3

=1/3

y intercept we have to find

0=1/3(3)+b

b=-1

So equation of line is y=1/3x-1

As the shading is away from origin, we use the greater than or equal to symbol.

y≥1/3x-1

Hence, the linear inequality represented by the graph  is y≥1/3x-1

=$362.5 per week

In a week Liam earns more

Answer:

The answer is the first choice and the last choice.

Step-by-step explanation:

The first one is already solved for y, so when you plug 9 into the equation in the x spot since 9 is the x-coordinate of the point, you get -2, which is correct because it is the corresponding y-value.

The second one is a mess when trying to solve and it clearly doesn't yield the right answer.

For the last one, when you solve for y and then plug in 9 for x, you get -2, the y-value making it correct.
