Answer:

2  to 8  and 8 to -2

Step-by-step explanation:

Solution to these set of inequalities is : 2 < x < 8  

Important Information

x + 7 > 9

x > 9 - 7

x > 2

8x < 16

x < 16/2

x <  8

So, numbers that satisfy the conditions that 2 < x < 8 are solutions to this set of inequalities.

[tex]\frac{3a^4b}{7}[/tex]

Step-by-step explanation:

thats the simplified version

Answer:

(I can not see the options, so I will answer in a general way)

When we have a system of linear equations:

y = a*x + b

y = c*x + d

We have 3 possible options:

One solution: This happens when the lines intersect only one time, and the solution of the system is the point where the lines intersect.

No solutions: This happens when the lines do not intersect, is the case for parallel lines (lines with the same slope but different y-intercept)

Infinite solutions: This happens when the lines do intersect at infinite points, is the case for two equal lines (so both equations represent the same line)

Now we have the system:

y = m*x  + b

y = -2*x + A

We want to find values of m and b, such that this system has no solutions.

Then we know that the lines must be parallel, again, the lines must have the same slope but different y-intercept.

Then we can use:

m = -2, b = A + 1

we will get:

y = -2*x + (A + 1)

y = -2*x + A

This system has no solutions.

Other pair can be:

m = -2, b = A + 3

we will get

y = -2*x + (A + 3)

y = -2*x + A

This system has no solutions.

Answer:

[tex]\frac{dZ}{dt}[/tex]= [tex]\frac{40}{\sqrt{545} }[/tex] , so the model car is moving away from the fixed point at a rate of approximately 1.7 feet per second.

Step-by-step explanation:

The functions x and y satisfy (x−20)^2+y^2=25 and differentiating gives 2(x−20)dx/dt+2y dy/dt=0. Substituting the three known values and solving for dy/dt yields dy/dt=−32. Since Z=x^2+y^2−−−−−−√, dZ/dt=(2x ^ dx/dt+2y^dy/dt) / 2x2+y2√. Substituting Since Substituting for x, y,[tex]\frac{dx}{dt}[/tex] , and [tex]\frac{dy}{dt}[/tex] gives [tex]\frac{dZ}{dt}[/tex]= [tex]\frac{40}{\sqrt{545} }[/tex] ,

Answer: DC=30.5

Step-by-step explanation:

Use trigonometry to solve this question

----------------------------------------------------------

First Step: find BD

- AB relative to 54° is [hypotenues]

- BD relative to 54° is [opposite]

- Therefore, we need to use O/H, which is Sin

- sin(54°)=O/20=20·sin(54°)=16.2

Second Step: Find DC

- DC relative to 28° is [adjacent]

- BD relative to 28° is [opposite]

- Therefore, we need to use O/A, which is tan

- tan(28°)=16.2/A=16.2/tan(28°)=30.5

Answer:

Thats the answer from american school

Step-by-step explanation:

The value of the common length BD would be 8 units aprroximately.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

Given information;

1. Considering line BD as a side of ABD, express its length in terms of variables representing side lengths and angle measures in ABD.

So, We know that

Sin A = BD / AB

Sin A = BD / c

c Sin A = BD

Substitute;

(10) Sin (53.13) = BD

BD = 10 ( 0.79)

BD = 7.99

Therefore, the value of the common length BD would be 8 units aprroximately.

Answer:

Step-by-step explanation:

Maria and Don has claimed $1839.8 as a medical deduction.

Calculate medical expenses after removing medical insurance expense, that is

20,800 - 60% of 20,800

= 12480

Now, 20,800-12480

=$8,320

Now calculate 10% of gross income

10% of 101,598

= 10/100 × 101,598

= 0.1 × 101,598

= $10,159.8

Now medical deduction = 10% of income - Medical expenses

= 10,159.8-8,320

= $1839.8

Therefore, the medical deduction is $1839.8.
