Answer:

[tex]y-10=5(x-7)[/tex]

Step-by-step explanation:

Point slope form: [tex]y-y_1=m(x-x_1)[/tex] where [tex]m[/tex] is the slope and the given point is [tex](x_1,y_1)[/tex]

Plug in the slope

[tex]y-y_1=5(x-x_1)[/tex]

Plug in the point (7,10)

[tex]y-10=5(x-7)[/tex]

Answer:

B 17.5 ft

Step-by-step explanation:

tangent = opposite / adjacent

tan 35° = h / 25

multiply both sides by 25

h = 25 (tan 35°)

tan 35° = 0.70 (from your calculator)

h = 25 (0.70)

h = 17.51 ft.

Answer:

Step-by-step explanation:

7) The tangent angles are 90° each.

The angles of a quadrilateral add up to 360°, so ? = 360°-90°-90°-73° = 107°.

8)  Solve this the same way as question 7). ? = 360°-90°-90°-57° = 123°.

Questions 9) and 10) are cut off, so I assume you don't need to know those.

Answer:

Proof of conceptual & numerical relationship between Total Pay, Pay rate per hr, No of hrs

Step-by-step explanation:

Total Pay = Pay rate per hr x No of hrs

No of hrs = Total Pay / Pay rate per hr

No of hrs = 119.70 / 12.6

No of hrs  = 9.5

2^4 = 16

Answer:

11: 416

Step-by-step explanation:

so the area of the rectangle is 20*16 and you add the triangle's area which is 96. 320+96=416. I am pretty sure that is the answer. ( Sorry if my drawing is bad) :D

Answer:

Cash price

Step-by-step explanation:

The computation is shown below:

The Interest rate per month (r) = (9% ÷ 12) = 0.75%

Now Present value of the monthly payment is

= PMT × {[(1 + rate of interest)^number of years - 1] ÷ rate of interest}

= 1,499 × {[(1 + 0.75%)^12 - 1] ÷ 0.75%}

= 18,748.89

And the cash price is 15,999

So, the cash price would be lower

The cash price would be lower. A further explanation is below.

According to the question,

Interest rate per month,

[tex]r = \frac{9 \ percent}{12}[/tex]

  [tex]= 0.75[/tex] (%)

hence,

The Present value of the monthly payment will be:

= [tex]PMT\times \frac{{(1 + Interest \ rate)^{number \ of \ years} - 1}}{Interest \ rate}[/tex]  

= [tex]1499\times \frac{[(1 + 0.75 \ percent)^{12} - 1] }{0.75 \ percent}[/tex]  

= [tex]18748.89[/tex]

As we can see that the cash price is 15,999. Thus the above answer is right.

An inequality is comparing of non-equal terms or expressions.

According to the given question we have to solve the given inequality and represent it in form of a number line with appropriate symbols.

Given,

-2(3x - 1) < 8.

- 6x + 2 < 8.

- 6x < 8 - 2.

- 6x < 6.

- x < 6/6.

- x < 1.

x > -1.         ( Think of moving the terms to the other side to make x positive )

This will be represented in a number line with open circle staring from -1 to positive infinity.
