Answer:

10 or 4.

Step-by-step explanation:

[(x - 7)^2 + 6 - 13 ] * 4 - 1 = 7

(x^2 - 14x + 49 - 7) * 4 - 1 = 7

4x^2 - 56x  + 196 - 28  - 1 - 7 = 0

4x^2 - 56x + 160 = 0

4(x^2 - 14x + 40) = 0

(x - 10)(x - 4) = 0

x = 10 , 4

vredina [299]

Answer:

A=630 in^2

Step-by-step explanation:

Triangles: there are two equal triangles so we can treat them as one rectangle

A = 15 * 14 = 210

Rectangle:

A=30 * 14 = 420

A_total = 210 + 420 = 630 in^2

andreyandreev [35.5K]

Answer:

20

Step-by-step explanation:

The number of combinations of 6 points taken 3 at a time is ...

6!/(3!·(6-3)!) = 6·5·4/(3·2·1) = 5·4 = 20

___

If you number the points 1–6, the points of the 20 triangles will be ...

123 124 125 126 134

135 136 145 146 156

234 235 236 245 246

Please help me I need this question done by tonight. The amount that a consultant charges for her work can be modeled using a li
nataly862011 [7]

Answer: The consultant earn $50 each hour.

Explanation:

It is given that for 4 hours of work, the consultant charges $400. For 5 hours of work, she charges $450. The amount that a consultant charges for her work can be modeled using a linear function.

If the linear function represents the amount earn by consultant in hours the the coordinates can be written as (4, 400) and (5, 450).

If we want to find how much money does the consultant earn each hour, so first we have to find the slope of linear function which passing through two points (4, 400) and (5, 450).

\text{Slope}=\frac{y_2-y_1}{x_2-x_1}

\text{Slope}=\frac{450-400}{5-4}

\text{Slope}=\frac{50}{1}

\text{Slope}=50

In the linear function the slope show the earning of consultant per hour, therefore consultant earn $50 each hour.
