____ [38]3 years ago

3 0

Answer:

Option A. There is no solution.

Step-by-step explanation:

we have

$y=3x-4$ ------> equation A

$9x-3y=14$ ------> equation B

substitute equation A in equation B

$9x-3(3x-4)=14$

$9x-9x+12=14$

$12=14$ ------> is not true

therefore

The system has no solution

<u>Explanation</u>

The slope of the line A is equal to $m=3$

Find the slope of the line B

$3y=9x-14$ ------> $y=3x-(14/3)$

The slope of the line B is equal to $m=3$

therefore

Line A and Line B are parallel lines, because the slope is the same

The system has no solution

IRINA_888 [86]

Answer:

38°; 142°; 308°

Step-by-step explanation:

The solution of each question is self-explanatory.

<u>Used properties</u>

Vertical angles are congruent
Angle sum property of circle
Central angle is same as intercepted arc measure

mED = mAB = mAC - mBC = 90° - 52° = 38°

mEA = mBCD = mBC + mCD = 52° + 90° = 142°

mBDC = 360° - mBC = 360° - 52° = 308°

Please help!! i have no clue what to do and this packet is due tonight.

Answer:

[D] ∞

General Formulas and Concepts:

<u>Calculus</u>

Limits

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em /> $\displaystyle \lim_{n \to \infty} s(n)$ <em />

<em /> $\displaystyle s(n) = (\frac{5}{4n^4})(3n^5 + 3n^4 + 2n^3 + n^2)$ <em />

<em />

<u>Step 2: Evaluate</u>

Substitute in function [Limit]: $\displaystyle \lim_{n \to \infty} (\frac{5}{4n^4})(3n^5 + 3n^4 + 2n^3 + n^2)$
Multiply: $\displaystyle \lim_{n \to \infty} \frac{5(3n^5 + 3n^4 + 2n^3 + n^2)}{4n^4}$
Power Method: $\displaystyle \lim_{n \to \infty} \frac{5(3n^5 + 3n^4 + 2n^3 + n^2)}{4n^4} = \infty$

Since the degree of the polynomial is greater in the numerator than in the denominator, the top will always increase faster than the bottom, thus getting infinitely larger.

Find the taxable income of a married couple with three children, who have a combined income of $62,000.

xeze [42]

Answer :

taxable income is $30,300

Step-by-step explanation:

Given

The combine income of the husband and wife = $62,000

Number of children the couple has = 3

In order to find out the taxable income for an U.S. family, the following formula is used

taxable income = total income - exemption deduction - standard deduction

We know the exemption deduction for a married couple with three kids fixed according to the U.S. government is $19,500.

And the standard deduction for a married couple with three kids fixed according to the U.S. government is $12,200.

Therefore,

taxable income = total income - exemption deduction - standard deduction

= $62,000 - $19,500 - $12,200

= $30,300

Thus the taxable income is $30,300.

Can someone please explain how to do this.

Cerrena [4.2K]

Well you can graph it by plotting 3 points then drawing a line through these 3 points. The graph will be a straight line . By plotting 3 points you can be more sure if you are right, because if you make a mistake then they might not make a straight line.

Put y = 0 in the equation and find the x coordinate:-

x + 5(0) = -20

x = -20

So we have one point to plot:- (-20,0)

Putting x = 0 we get 5y = -20 so y = -4

Second point:- (0, -4)

Putting x = 5 say we get 4 + 5y = -20 so y = -25/5 = -5

so our 3rd point is (5, -5)
