Answer:

equation 1

y = -2x

equation 2

y = x-3

Solution to both

(1,-2)

Step-by-step explanation:

We need to get the equations of both lines

General form is;

y = mx + c

where m is slope and c is the y-intercept

Table 1

since we have a point 0,0; the y-intercept here is zero

Let us get the slope. We can do this by selecting any two points

m = (y2-y1)/(x2-x1)

m = (2-10)/(-1+5) = -8/4 = -2

So the equation of the first line is;

y = -2x

Table 2

we get the slope

m = (4+2)/(7-1) = 6/6 = 1

The partial equation is;

y = x + c

To get c, we select any two point and substitute

4 = 7 + c

c = 4-7

c = -3

So the equation is;

y = x-3

To get the solution to both systems, we equate the y

-2x = x - 3

-2x-x = -3

-3x = -3

x = -3/-3

x = 1

To get y, we substitute;

recall; y = -2x

y = -2(1)

y = -2

Solution to the system is;

(1,-2)

Step-by-step explanation:

Only option B shows a proportional relationship (y = 3x).

Answer:

D

Step-by-step explanation:

Y=3x-1 is written as the slope-intercept form y=mx+b don't let the -1 confuse you.

Step-by-step explanation:

Given

5x + 2x + 2 = 9x + 4

9x - 5x - 2x = 2 - 4

9x - 7x = - 2

2x = - 2

x = - 2 / 2

Therefore x = -1.

therefore lhs is equal to rhs

Answer:

About 15 minutes

Step-by-step explanation:

It takes her 6 minutes to read 20 pgs. If she reads 20 more pages (which will be 40 now) she will have been reading for 12 minutes. This leaves you with 7 pages left, about 3 or 4 minutes.

Answer:

  AB = 7

  AC = 21

Step-by-step explanation:

Because AD is an angle bisector it divides the triangle into proportional parts. That is ...

  AC/DC = AB/BD

  (28 -AB)/9 = AB/3 . . . . use AC = 28 -AB

  28 -AB = 3AB . . . . . . . . multiply by 9

  28 = 4AB . . . . . . . . add AB

  AB = 28/4 = 7 . . . . divide by 4

  AC = 28 -7 = 21

The lengths AB and AC are 7 and 21, respectively.

Additional comment

The triangle ABC cannot exist. The reason is that its side measures are 7, 12, and 21. The sum of 7 and 12 is not greater than 21, so the side measures do not satisfy the triangle inequality.

For the triangle to exist, the sum of AB and AC cannot exceed 24 for the given values of BD and DC.

Answer:

The numbers associated with the triangle are 5.437 and 6.437 centimeters, respectively.

Step-by-step explanation:

Two numbers are consecutives, when their difference is equal to 1. The area of the triangle is determined by the following formula:

[tex]A = \frac{1}{2}\cdot n \cdot (n+1)[/tex]

[tex]A = \frac{1}{2}\cdot (n^{2}+n)[/tex]

[tex]A = \frac{n^{2}}{2}+\frac{n}{2}[/tex]

[tex]n^{2}+n = 2\cdot A[/tex]

Where [tex]n[/tex] is the shortest length of the triangle, measured in centimeters.

And we get the following second-order polynomial:

[tex]n^{2}+n -2\cdot A = 0[/tex] (1)

If we know that [tex]A = 17.5\,cm^{2}[/tex], then the shortest length of the triangle is:

[tex]n_{1} = 5.437\,cm[/tex] and [tex]n_{2} \approx -6.437\,cm[/tex]

Since length is a positive variable, the only possible solution is:

[tex]n\approx 5.437\,cm[/tex]

Then, the numbers associated with the triangle are 5.437 and 6.437 centimeters, respectively.

Answer:

200%

Step-by-step explanation:

if you substitute in numbers you'll find this as the answer.

as an example:

suppose the sides of the rectangle was 1 unit long.

area before change: 1 * 1 = 1

then, the length gets increase by 50% making it 1.5 ( 50% of 1 is 0.5, then you add it onto 1, 1 + 0.5 = 1.5 )

the width gets increased by 100% making it 2 ( 1 + 1 = 2 )

new area: 1.5 * 2 = 3

1 increased by 200% is 3, therefore the answer is 200%

The final price including tax is $41.89

Step-by-step explanation:

The following items are on sale:

Sleeved dress $17.99

Skirt $16.19

T-shirt $8.99

Subtotal $43.17

The cheapest item is the T-shirt for $8.99 and it will be discounted by 30%:

$8.99 - 30/100 * $8.99 = $8.99 - $2.70 = $6.29

The total sale price is now: $43.17-$2.70=$40.47

Now we add the 3.5% tax:

$40.47 + 3.5/100 * $40.47 = $40.47 + $1.42 = $41.89

The final price including tax is $41.89

Answer:

There are 3 intervals where Ann is driving a consistent speed

==========================================================

Explanation:

When she drives a consistent speed, this means her speed is the same.

This happens exactly when there are flat portions of the graph. This is because the speed y is not going up or down during these intervals.

The intervals where the graph is flat are mentioned at the top in the answer portion.

Any time the graph goes uphill, from left to right, Ann is increasing her speed. So she is accelerating.

In contrast, any time the graph goes downhill, she is decreasing her speed (or decelerating).

Side note: I'm not including the portion from roughly 4 to 5 minutes because during that time, she is stopped and the car isn't moving.

Step-by-step explanation:

Answer:

Y=6x+20

Step-by-step explanation:

Answer: ASA: If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent. SAS: If any two angles and the included side are the same in both triangles, then the triangles are congruent.

An equilateral polygon has congruent sides, like a rhombus.

An equiangular polygon has congruent interior angles, like a rectangle.

In other words: Equilateral doesn't necessarily have congruent INTERIOR angles while equiangular does have/need congruent interior angles.

Answer:

x=1337/528

Step-by-step explanation:

-314x-214x=-1312-25

-528x=-1337

x=1337/528

Answer:

Step-by-step explanation:

add 314x to both sides

-314+25=214x-1312

+314x     +314x

add 1312 to both sides

25=528x-1312

+1312       +1312

1337=528x

x=1337/528

i dont thing you can simplify to a whole number...hopefully this helps a little :)
