Solve the system and determine whether it is consistent or inconsistent and dependent or independent.
y = -5x – 2
5x + y = 0

Answers

-2≠0 Inconstant and dependent

Substitute y for -5x-2
So instead of “5x+y=0” it’s
5x-5x-2
5x-5x is obvious 0
0-2 = -2
-2 ≠ 0
Because -2 does not equal 0 it is inconsistent
Because you could not figure out that y is -5x -2 in this case, it in dependent

Nancy lives in a state where sales tax is 9%. This means you can find the total cost of an item, including tax, by using the expression c + 0.09c, where c is the pre-tax price of the item.

Use the expression to find the total cost of an item that has a pre-tax price of $84.00.

Answer:

  $91.56

Step-by-step explanation:

We can simplify Nancy's cost expression to ...

  c +0.09c = c(1 +0.09) = 1.09c

The the total cost of the item of interest is ...

  (1.09)($84) = $91.56

What is Circle?

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Given that at the center of a circular pond, there is apole of 11.63 high above the surface of water from a point on the edge of a pond.

A man of 1. 62 m high observed the angle of elevation of the top of the pole and found to be 60degree

We need to find the diameter.

tan60=11.63-1.62/r

r=10/tan60

r=10/√3

r=5.77

We know that diameter is twice the radius

d=2r

d=2(5.77)

d=11.54

Hence, the diameter of the pond is 11.54 m.

solve 17+6p=9
pls explain​

Answers

17+6p=9
6p=9-17
6p= -8
p= -8/6
p=-4/3
17 + 6p = 9
First we want any number with p on one side and all the other numbers on the opposite side. So we’ll subtract 17 from both sides of the equation.

6p = -8

Then we need to divide both sides by 6 to find p

p = -8/6

Most teachers want the fraction reduced, so it would be -4/3 or - 1 1/3

Can anybody help me please?

Answers

Answer: X=-3.

Anne was correct at fist, but likely didn’t solve the rest of the equation. The correct answer is X=-3, from 5(2x - 3)= 20x + 15, simplified by the distributive property going to 10x - 15 = 20x + 15. You then subtract +15 from the right side, or left side if you want to have a more positive answer, though it depends. That leaves you with 10x - 30 = 20x.  You subtract 10x from itself and from 20x. Then you have -30 = 10x. You divide 10x by -30, and you get -3. Therefore, X = -3.

Find the equation of the line given the two points below

A(−3,−2) B(6,−8)

Answers

Answer:

y = -2/3x - 4

Step-by-step explanation:

Formula: y = mx + b

m (slope)

b (y-intercept)

Slope Formula: y2 - y1 ÷ x2 - x1

Substitute: -8-(-2) = -8+2 = -6

6-(-3) = 6+3 = 9

-6/9 (funny, I know)

Simplify --> -2/3

slope = -2/3

Substitute for the y-intercept --> to do this, we plug in a coordinate pair

-8 = -2/3(6) + b

-8 = -4 + b => add 4 to both sides

b = -4, and thus, our y-intercept is -4

Plug our values into the formula: y = mx + b

y = -2/3x + (-4)

simplify to get our final equation

y = -2/3x - 4

Answers

Answer:

Step-by-step explanation:

Explicit formula of a G.P. is given by,

[tex]a_n=a(r)^{n-1}[/tex]

Here, [tex]a_n[/tex] = nth term

a = First term

n = number of term

r = common ratio

Given sequence is 3, 6, 12, .......

a = 3

r = [tex]\frac{6}{3}[/tex] = 2

Therefore, explicit formula will be,

[tex]a_n=3(2)^{n-1}[/tex]

Option (3) is the answer.

Parent function → f(x) = 3ˣ

Transformed function → g(x) = [tex]3^{x+5}[/tex]

Since, g(x) = f(x + 5)

Therefore, function 'f' has been shifted 5 units left.

Option (1) is the answer.

Answer:

  G: $27

  H: $25

Step-by-step explanation:

In each case, the "initial cost" is the cost when the number of hours is zero.

For company G, it is ...

  c = 27 + 10·0

  c = 27

For company H, it is 25 (corresponds to Hours = 0).

__

The initial costs are ...

  G: $27

  H: $25

_____

Additional comment

The cost per hour is found from the equation by looking at the coefficient of h. It is $10 per hour for Company G.

The cost per hour is found from the table by looking at the increase when the number of hours increases by 1. For 1 hour, the cost goes from 25 to 32, an increase of $7 for 1 hour. The cost is $7 per hour for Company H.
