What is X2 + 3(4) - 1 = 47?​

Answers

Answer 1

Answer:

x=6, -6

Step-by-step explanation:

take the root of both sides then solve

Answer 2

Answer:

x = 18

Step-by-step explanation:

2x + 3(4) - 1 = 47

Begin by combining your like terms

2x + 12 - 1 = 47

2x + 11 = 47

Isolate your variable (x) by using inverse operations

2x = 36

x = 18

Let xy=3 and dy/dt=4. Find dx/dt when x=5

Answers

Answer:

xy = 3

d/dt(xy) = d/dt(3)

ydx/dt + xdy/dt = 0

y = 3/x so substitute 3/5 for y, 5 for x, and 5 for dy/dt; and solve for dx/dt.

3/5(dx/dt) + 5(5) = 0

3/5(dx/dt) = -25

dx/dt = -125/3

which of the lines graphed has a slope of -1/2 and a y-intercept of 3?

Answers

Answer:

The answer is image 3.

Step-by-step explanation:

The equation for the line will be y = (-1/2)x + 3 so the gradient is negative and you will have to find the x-intercept and y-intercept.

x-intercept :

[tex]let \: y = 0[/tex]

[tex]0 = - \frac{1}{2} x + 3[/tex]

[tex] \frac{1}{2} x = 3[/tex]

[tex]x = 3 \div \frac{1}{2} [/tex]

[tex]x = 6[/tex]

y-intercept :

[tex]let \: x = 0[/tex]

[tex]y = - \frac{1}{2} (0) + 3[/tex]

[tex]y = 3[/tex]

The equation of a line parallel to line 3y - 2x = 9,
passing through point P(6, 2) is
(a) y - 6 = }(x - 2)
(b) y - 2 = (x-6)
(c) y - 2 = }(x-6)
(d) y – 2 = } (x + 6)

Answers

Answer:

The equation of the line is

y-2 = 2/3(x-6)

Step-by-step explanation:

The standard form of the straight line equation is;

y = mx + b

where m is slope

so ;

3y = 2x + 9

y = 2x/3 + 3

If two lines are parallel, then their slopes are equal

This mean that the slope of the line of the new equation is 2/3 too

Thus;

(y-2) = 2/3(x - 6)

3(y-2)= 2(x-6)

3y - 6 = 2x - 12

3y = 2x -12 + 6

3y = 2x - 6

Answers

Answer:

a) (x + 8) (x + 2)

b) (x + 4) (x + 3)

c) (x + 12) (x + 1)

Step-by-step explanation:

First find the multiples of coefficients of a and c (ax² + bx + c)

Then rearrange it to make it add/subtract to make the number in the middle (b in bx).

a). Look at the multiples of 16.

4 x 4 .... 4 + 4 ≠ 10

8 x 2 .... 8 + 2 = 10

1 x 16 .... 1 + 16 ≠ 10

The factors of 16 that add up to 10 are 8 and 2.

Hence we write it like (x + 8) (x + 2), and to check this you can expand it.

Same goes for b and c

b). Multiples of 12 that add up to 7 are 3 x 4 ===> (x + 3) (x + 4)

c). Multiples of 12 that add up to 13 are 1 x 12 ===> (x + 12) (x + 1)

Answer:

  your choice is the best

Step-by-step explanation:

If you simply look at the segments marked with expressions in z, you have* ...

  z+23 > 0   ⇒   z > -23

  3z +9 > 0   ⇒   z > -9/3 = -3

That is, the side lengths must be positive. We must also have the side labeled z+23 be longer than the side labeled 3z+9:

  z +23 > 3z +9

  14 > 2z . . . . . . . subtract z+9

  7 > z

So, the limits on the marked side lengths require ...

  -3 < z < 7 . . . . matches the 4th choice

__

If you actually work out the possible sizes of these triangles such that the angles are the given measures, you find that the minimum length of the legs with the hash mark is about 15.8649, and the minimum value of z is ...

  z > (12√6 -7)/5 ≈ 4.47878

This value is obtained when the triangles are isosceles. Apparently, you're not supposed to think that deeply about this question.

_____

* The "or equal to" case is not included, because that would allow the triangles to have zero area. That is, the triangles would be a single point.

Answer:

4x + (6(x-y)) or 10x + 6y

Step-by-step explanation:

A Pear costs (x) Pesos

An Orange costs (y) Pesos less than a Pear

Since an Orange is (y) Pesos less than a pear (x), we can find the cost of a Pear by subtracting (y) from (x) leaving (x-y) as the cost of an Orange

Since there are 4 Pears we use 4(x) to find the cost of Pears and to get the total cost of it all we use a half dozen (6) and use the equation for the cost of an Orange leaving us with 6(x-y)

The final total will be calculated with 4(x) + (6(x-y))

Or the final total can be simplified as 10x + 6y

Answer:

10x - 6y

Step-by-step explanation:

4x + 6 ( x - y )

= 4x + 6x - 6y

= 10x - 6y
