2x - 5y = -14

Answers

Answer 1

Answer:

{x,y} = {33/19,-2/19}

Step-by-step explanation:

Answer 2

Answer: For 5x-3y=-11, the answer is y=11/3 + 5x/3.

For 2x-5y=-14, the answer is y=14/5 + 2x/5

Step-by-step explanation: Move all terms that do not contain y to the right side and then solve.

Evaluate the function f(x)=6x+2 at the given values of the independent variable and simplify.
a. f(8) b. f(x+6) c. f(−x)
. f(8)= (Simplify your​ answer.)

Answers

[tex]f(x) = 6x+2[/tex]

A.

To evaluate f(8), we substitute x with 8 in our expression.

[tex]f(8) = 6*8 + 2\\f(8) = 48 +2\\f(8) = 50[/tex]

Answer: f(8) = 50

B.

To evaluate f(x+6), we do the same but substitute x with x+6 instead.

[tex]f(x+6) = 6(x+6) + 2[/tex]

Expand the parenthesis by multiplying 6 with x and 6.

[tex]f(x+6) = 6x + 6*6 + 2\\f(x+6) = 6x+36+2\\f(x+6) = 6x+38[/tex]

Answer: f(x+6) = 6x + 38

C.

Again, we're doing the same thing, just substituting x with -x.

[tex]f(-x) = 6 * (-x) + 2\\ f(-x)=-6x+2[/tex]

Answer: f(-x) = -6x+2

Answer:

_____________________________________________

[tex] \longmapsto \: f(x) = 6x + 2[/tex]

_____________________________________________

A. [tex]f(8) = 6(8) + 2 = 48 + 2 = \boxed{ 50}✓[/tex]

_____________________________________________

B. [tex]f(x + 6) = 6(x + 6) + 2 \\ = 6x + 36 + 2 \\ = \boxed{ 6x + 38}✓[/tex]

_____________________________________________

C. [tex]f( - x) = 6( - x) + 2 = \boxed{ - 6x + 2}✓[/tex]

Answer:

no i dont think so

Step-by-step explanation:

1) multiply both sides by p

5/9=-10p

2) divide by -10 to get p

5/9 divided by -10/1

(keep, change flip)

5/9* -1/10

-5/90

therefore p=-5/90

Answer:

No, the answer is -18

Step-by-step explanation:

[tex]\frac{5}{9}[/tex]p = -10

[tex]\frac{5p}{9}[/tex] = -10            CROSS MULTIPLY

-90=5p             DIVIDE BOTH SIDES BY 5

The midpoint of AB is M(2, -1). If the coordinates of A are (1,6), what are the
coordinates of B?

Answers

Answer:

work is attached and shown

The coordinate of point B will be (3, -8) for the given line segment.

What are coordinates?

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

For example (5,3) here 5 will be for the x and 3 will be for the y.

Another example is (9,0) here 9 is for x and 0 is for y.

Given the line segment, AB

If the M(2, -1) is the midpoint of A(1,6) and B(x,y)

Then,

(1 + x)/2 = 2 ⇒ x = 3

(6 + y)/2 = -1 ⇒ y = -8

So B(3, -8).

Hence "The coordinate of point B will be (3, -8) for the given line segment".

P= 29.95 + 0.05m +2.95
d. P= (29.95 + 0.05)m +2.95. What equation should I use?

Answers

Answer:

[tex]P=29.95+0.05m+2.95[/tex]

Step-by-step explanation:

The monthly plan costs starts at $29.95, so we're not changing that.

For each monthly plan, we have to pay a tax of $2.95, so we're not changing that.

If we go over 1,000 minutes, we have to pay $0.05 for every minute we go over, and with the fact that [tex]m[/tex] represents each minute over 1,000, we're going to have to represent minutes over 1,000 as [tex]0.05m[/tex] in our equation.

Set up your equation:

What is a number line?

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.

The given numbers are: −12/5 and –2.8

As we can re-write -12/5 in decimal form= -2.4

Now, we need to mark the number on the number line.

As the number -2.4 lies between -2 and -3 on the left side of zero.

and, -2.4 lies between -the numbers 2.5 and -3.0 on the left side of zero.

Simplify 12edf – 13def. State a property that you can use.

Answers

Answer:

-def. In multiplication, the order doesn't matter.

Step-by-step explanation:

A crucial property you can use to simplify this is the fact that, in multiplication, order doesn't matter.

3 * 2 = 6

2 * 3 = 6

5 * 2 * 3 = 30

2 * 3 * 5 = 30

3 * 2 * 5 = 30

Thus,

edf, or

e * d * f

is the same as def,

d * e * f

e * d * f = d * e * f

edf = def

Thus, 12edf is the same as 12def. We can put this in our expression:

12edf - 13def

12def - 13def

Now, we can see that this will equal -1def or -def

12def - 13def

-1def

-def

Answer: -def. In multiplication, the order doesn't matter.
