Answer:

Wheres the question then i'll help

Step-by-step explanation:

The solution to the system of equations is A. (-2, 2)

The system of equation was:

2x + 3y = 2 ..... i

y = 1/2x + 3 ...... ii

Substitute equation ii into i

2x + 3/2x + 9 = 2

Multiply through by 2.

7x + 18 = 4

7x = -14

Divide

x = 14/7

x = -2

Also, y = 1/2x + 3

y = 1/2(-2) + 3

y = -1 + 3

y = 2

Therefore, the solution to the system of equations is (-2, 2).

Answer:

  (13.06, 16.41)

Step-by-step explanation:

Any point not on a perpendicular bisector of the line between towns will be closer to one town than the other. So, the intersection of perpendicular bisectors will be the equidistant from all towns. That point is the circumcenter of the circle circumscribing the triangle with the towns as its vertices. This can be found as the intersection of two perpendicular bisectors of the segments between the towns.

The midpoint of AB is ...

  (A +B)/2 = ((15, 3) +(25, 10))/2 = (40, 13)/2 = (20, 6.5)

The midpoint of AC is ...

  (A +C)/2 = ((15, 3) +(0, 20))/2 = (15, 23)/2 = (7.5, 11.5)

__

The differences between points are ...

  B -A = (25, 10) -(15, 3) = (10, 7)

  C -A = (0, 20) -(15, 3) = (-15, 17)

Then the perpendicular bisector equations can be written as ...

  bisector of AB  ⇒  10(x -20) +7(y -6.5) = 0

     10x +7x -245.5 = 0

  bisector of AC  ⇒  -15(x -7.5) +17(y -11.5) = 0

     -15x +17y -83 = 0

These have coefficients that aren't particularly nice, so a method similar to Cramer's Rule is suitable for solving this pair of equations. Using the "cross multiplication method", we have ...

  x = (7(-83) -17(-245.5))/(10(17) -(-15)(7)) = 3592.5/275 = 13 7/110 ≈ 13.06

  y = (-245.5(-15) -(-83)(10))/275 = 4512.5/275 = 16 9/22 ≈ 16.41

The point as far as possible from each town within the boundary of the island has coordinates (13.06, 16.41).

_____

Further detail regarding the solution

Here, we have written the equation for the perpendicular bisector this way. The difference in coordinates between points R and S can be called ...

  R -S = (∆x, ∆y)

The midpoint of segment RS can be called ...

  (R +S)/2 = (h, k)

Then the line that is a perpendicular bisector of RS can be written as ...

  ∆x(x -h) +∆y(y -k) = 0

This is the form that is used above.

__

The "cross multiplication method" for solving a pair of general-form linear equations ...

  ax +by +c = 0

  dx +ey +g = 0

will give the solution as ...

  1/(ae -db) = x/(bg -ec) = y/(cd -ga)

If you write the coefficients in two rows of four, the pattern of products and differences is easy to see.

Answer:

$635

Step-by-step explanation:

She made a total of $959 anad last year she made $324 so you then subtract the ammounts because the problem wants to know how much MORE she made.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

The more amount made this year is $635.04

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Your friend made $324 babysitting last year.

This year she made 296% of what she made last year.

This means,

The amount this year.

= 296/100 x 324

= $959.04

The difference in the amount.

= $959.04 - $324

= $635.04

The difference in the amount can also be calculated as,

= 296% - 100%

= 196% more this year.

So,

196% of $324

= 196/100 x 324

= $635.04

Thus,

The more amount made this year is $635.04

Answer:

98 teaspoons

Step-by-step explanation:

Aashvi is making garlic naan. The recipe calls for 2 cups of flour, but Aashvi only has teaspoons. If 24 teaspoons are equal to 1/2 cup, how many teaspoons will Aashvi use to measure 2 cups of flour? *

From the above question, we understand that:

1/2 cup of flour = 24 teaspoons

2 cups of flour = x teaspoons

Cross Multiply

1/2x = 24 × 2

x = 48 ÷ 1/2

x = 48 × 2

x = 98 tea spoons

Therefore, Aashvi will use 98 teaspoons to measure 2 cups of flour.

Answer:

Step-by-step explanation:

The function that describes the one-sided limits at x = c.

[tex]\lim_{x \to c^-} g(x) = a\\\\ \lim_{x \to c^-} g(x) = a[/tex]  ( for some value of a).

A discontinuity is removable if the limit of the function at the point of discontinuity exists and the value of the function exists but they aren't equal to each other.

We can remove that discontinuity by making the value of the function equate to the limiting value of the function at that point.

Function g(x) has a removable discontinuity at x = c,

where g(c) is undefined.

In this case, the statement that's is true for g(x) is that you can remove the discontinuity at x = c by defining g(c) = a.

The function that describes the one-sided limits at x = c.

x = 30

Step-by-step explanation:

The interior angles of a triangle must always add up to 180.

2x + 2x + 3x - 30 = 180

Add 30 to both sides to seperate variables.

2x + 2x + 3x = 210

Combine like terms.

7x = 210

Divide by 7 to isolate x.

Step 1: Define inequality

7r + 8 > 64 - r

Step 2: Solve for r

Here we see that any value r greater than 7 would work as a solution to the inequality.

The value is less than 1 and the impact of the negative exponent is that it moves the decimal point to the left

Standard form can be defined as a mathematical way of writing large or too small numbers in a defined manner.

Given the standard form;

Answer:

120

Step-by-step explanation:

By the rule of opposite angles, we can determine that x=120 because:

AB is parallel to CD

120 degree angle (let's call it Y) is on AB

X (we can see that it is obtuse) is on CD

So, Y is congruent to X, vice versa, so x=120
