is the length of each segment?

Answers

Answer:

are congruentlength: 16 units

Step-by-step explanation:

The length of a segment on a number line is the difference of its coordinates.

AB = 9 -(-7) = 16

CD = 12 -(-4) = 16

AB and CD both have a length of 16 units, so are congruent.

20 points!!!! Freya is collecting 50p and £1 coins. When she has 18 coins the value of them is £13.

Let x be the number of 50p coins and y the number of £1 coins. Write a pair of simultaneous equations for this.

Answers

Answer:

x + y = 180.5x +y = 13

Step-by-step explanation:

The system of equations formalizes the given relationships regarding the number of coins and their value.

x + y = 18 . . . . . . Freya has 18 coins

0.50x +1.00y = 13 . . . . their value is £13

_____

Additional comment

The solution can be found by subtracting the second equation from the first:

0.5x = 5

x = 10

y = 18 -10 = 8

Freya has 10 50p coins and 8 £1 coins.

Answer:The answer is A (4, 4)

Step-by-step explanation: When reflected across the y-axis, the y coordinates stay the same, but the x coordinated change signs. In this case, the original x coordinate was -4. But after flipped across the y axis, the -4 changes to a positive 4, since it is in quadrant 1.

Start with definition of absolute value, |x|.

It says, |x| = x, for any x >= 0 and

|x| = -x, for any x < 0

Now, instead of x, we have the expression x+120 inside the absolute value brackets:

|x+120|

Play the same game as above - what is the absolute value here?

|x+120| = x+120 for (x+120)>=0 and

|x+120| = -(x+120) for (x+120)<0

Now, recognize that the last condition (x+120)<0 is the same as writing x<-120. That is the condition in the question. Therefore the absolute value |x+120| will equal the second expression (for that condition), namely -(x+120), or -x-120.

Answers

Answer:

A and C

Step-by-step explanation:

When you are dividing exponents you subtract. So for this problem -8 - -4 = -8 + 4 = -4. This means that the new exponent would be -4.

When you have a negative exponent, the equation is a fraction. As an example x^-5 would be equal to 1/x^5. For this equation, since you know that the new exponent is -4, an equivalent equation would be 1/3^4.

Answers

Answer:

1. D

2. B

3. A

4. C

Step-by-step explanation:

1. The third side can't be calculated with given information

2. This is right triangle so you can use Pythagorean theorem to find hypotenuse.

6^2 + 8^2 = c^2

36 + 64 = c^2

100 = c^2

10 = c = PR

Since PM = RM, you would take half of c to find PM. So PM = 5

3. When writing congruency statement, you have to be careful with orders.

Angle A is congruent to angle E.

Angle B is congruent to angle D

So if A comes first, then E should be written first for the other side (does that make sense?)

4. For SAS, you need 2 congruent sides and 1 congruent angle. But that angle has to be in between two congruent sides.

6x+7y=20

y=2x

we second equation is basically telling us that y=2x so we just plug it into the first equation

6x+7(2x)=20

distribute

6x+14x=20

combine like terms

20x=20

divide each side by 20

x=1

now plug in our answer into one of the equations (does not matter which one)

y=2

meaning that our answer is (1,2), x=1 y=2

Answer:

1. width = 4 inches length = 13 inches

2. 225 m²

Step-by-step explanation:

1. So we know there are two sides and one side is 9 more than the other.

We let one side be x as we don't know what the number is. The other side is x+9 as its 9 more than the first side but we don't what that is either.

We know the area of a rectangle is A = bh.

The two sides are x and x+9

so, x(x+9) = 52

x² + 9x = 52

x² + 9x - 52 = 0

x² + 13x - 4x - 52 = 0

x(x+13) -4(x+13) = 0

(x-4)(x+13) = 0

x = 4 x = 13

The answer is x = 4 because you can't have x = -13 as negative lengths don't exist.

So if one side is x and the other side is x+ 9. Then plugging in 4 to both gets us, 4 and 13 as the dimensions.

The length is 9 more than width so,

length = 13 inches and width = 4 inches.

2. We know the area of a rectangle is A = bh.

One side is x + 10 and the other is x+15

Area is 750.

(x+10)(x+15) = 750

x²+15x+10x+150 = 750

x²+15x+10x-600 = 0

x²+25x-600 = 0

(x+40)(x-15) = 0

x = 15 as we can't have x = -40 because negative distance does not exist.

The bistro has sides x and x.

So the area is x * x.

15 * 15 = 225 m².

Answer:

25 miles, and the cost will be $37.50.

Step-by-step explanation:

Mose's charge can be represented by f(x) = 0.5x + 25, Holly's charge can be represented by g(x) = 0.3x + 30.

Set the equations equal to each other: 0.5x + 25 = 0.3x + 30.

0.2x = 5

x = 25

Substitute 25 for x: f(x) = 0.5(25) + 25 = 37.5, g(x) = 0.3(25) + 30 = 37.5.

So f(x) = g(x) at x = 25, and the output will be 37.5.

Answers

Answer:

ill try:

Learning about the connections between finding the GCF of numbers, the distributive property, multiplying polynomials, and factoring has helped me understand how to simplify and solve for equations. The distributive property taught me about how to easily simplifying equations, since the requirement is to just distribute the given to the number(s). Factoring has taught me how to make an equation easier to solve. For example, when I'm given a problem that has very large numbers, I can see if they have a GCF and this will help me solve the problem in no time!
