Would anyone help With these questions it's the last one I don't know how to do them 1,2,3,4,5 and 6

Shtirlitz [24]

Answer:

See below

Step-by-step explanation:

1. Use x to designate the number of hours worked.

Plumber 1 = 35(x) + 25

Plumber 2 = 40(x)

Now you need to find when these two equations are equal to each other.

35(x) + 25 = 40(x)

Solve for x.

25 = 40x - 35x

25 = 5x

5 = x

So when the service call equals 5 hours, both plumbers will charge the same amount of money.

2. Use x to designate the number of months.

Center 1 = 30x

Center 2 = 22x + 80 initiation fee

Now you need to make the two equations equal to each other and solve for x.

30x = 22x + 80

30x - 22x = 80 or 8x = 80

x = 10 months

3. Use x to designate the pounds of the package

Shipper 1 = 14 + 2x

Shipper 2 = 20 + 1.5x

Make the two equations equal to each other.

14 + 2x = 20 + 1.5x

2x - 1.5x = 20 - 14

0.5x = 6

x = 12 pounds

4. Deanna $15 using $0.75 per game. This means she can play a total of 20 games before having $0.

Lise $13 using $0.50 per game. This means she can play a total of 26 games before having $0.

So since both end up with $0, you can see that Deanna would play 20 games and Lise would play 26 games.

5. Use x to designate the call time length.

Hotel 1 = 1 + 0.80x

Hotel 2 = 2 + 0.75x

Make both equations equal to each other.

1 + 0.8x = 2 + 0.75x

0.8x - 0.75x = 2 - 1

0.05x = 1

x = 20

6. Use x to designate semesters.

Duke = 22 + 6x

Kila = 4 + 12x

22 + 6x = 4 + 12x

22 - 4 = 12x - 6x

18 = 6x

3 = x semesters

A line has a slope of 1and passes through the point

Jobisdone [24]

$\huge\boxed{y=x-3}$

Start with point-slope form, where $m$ is the slope and $(x_1, y_1)$ is a known point on the line.

$y-y_1=m(x-x_1)$

Substitute in the known values.

$y-3=1(x-6)$

Distribute the $1$ to the $(x-6)$ .

$y-3=x-6$

Add $3$ to both sides.

$\boxed{y=x-3}$

What is the slope of the line shown below?

fiasKO [112]

Answer: The slope of the line can be determined from the gradient equation, rise (y axis)/ run (x-axis)

Hence let (-1, 8) be A and (2, -4) be B. The slope from A to B is (-4-8)/(2-(-1))= (-12)/3= -4

Hence the gradient/ slope of the line is -4.

What is the area of the figure? /Users/macuser/Downloads/MS_IMB-1401012-1100604.jpg

xeze [42]

Given:
Shapes: Trapezoid and Triangle.

Trapezoid: Upper base = 14mm ; lower base = 18mm
Triangle: base = 18mm ; height = 12mm
Total height of the figure is 17 mm

Area of a trapezoid = (upper base + lower base)/2 * height
A = (14mm+18mm)/2 * (17mm-12mm)
A = 32mm/2 * 5mm
A = 16mm * 5mm
A = 80 mm²

Area of a triangle = (height * base) ÷ 2
A = (12mm * 18mm) ÷ 2
A = 216mm² ÷ 2
A = 108 mm²

Total area of the figure = 80 mm² + 108 mm² = 188mm²

Which statements are true about the graph of

Yuri [45]

Answer:

The area below the line is shaded.

Step-by-step explanation:

Using the zero-interval test [test point (0, 0)], we plug in 0 for both y and x to determine whether we shade below the line [the portion that DOES contain the origin] or above the line [the portion that does not contain the origin]. This is where me must verify the inequality as false or true:

$\displaystyle 0 < 2[0] + 1 → 0 < 1$

This is a genuine statement, therefore we shade below the line.

I am joyous to assist you anytime.
