!!URGENT!!
Camila has had a collection of sports cards for several years. If the time in years since the collection started is represented by t, and the number of cards in the collection is represented by B, match each of the statements below with an equation that models the function described. Camila had started her collection with 250 cards and her collection decreased by 60 cards each year. Camila didn't have any cards when she started her collection, but her collection grew by 60 cards each year.

Answer:

250%

Step-by-step explanation:

1.0 = 100%

2.0 = 200%

0.5 = 50%

Therefore, 2.5 = 250%

Answer:

the answer is A: the statement is true

It is given that Any sequence of rigid motions preserves the size of the transformed figure. Thus, This statement is true. so option A is correct.

A rigid transformation is a transformation of the plane that preserves length. In a rigid transformation the initial shape and the image shape are congruent.

There are Main properties: 

1. The distance (lengths of segments remain the same)

2. The angle measures (remain the same)

3. The parallelism (parallel lines remain parallel)

4. A collinearity (points remain on the same lines)

5. An orientation (lettering order remains the same)

It is given that Any sequence of rigid motions preserves the size of the transformed figure.

Thus, This statement is true. so option A is correct.

Answer:

The vertex of this parabola is [tex](-2,-11)[/tex]

Step-by-step explanation:

One way of finding the x-coordinate of the vertex of a parabola is by using the equation [tex]-\frac{b}{2a}[/tex]

From the function [tex]f(x)=x^2+4x-7[/tex], we can see that

[tex]a=1\\b=4\\c=-7[/tex]

This means that

[tex]-\frac{b}{2a}=-\frac{4}{2(1)} =-2[/tex]

So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.

[tex]f(x)=x^2+4x-7\\\\f(-2)=(-2)^2+4(-2)-7\\\\f(-2)= 4-8-7\\\\f(-2)=-11[/tex]

Thus, the vertex of this parabola is [tex](-2,-11)[/tex]

If you doubled an unknown number and subtract 1 and then square the answer to get 64, the unknown number is 4.5.

Given the following data:

To find an unknown number:

In this exercise, you're required to solve for an unknown number while performing some arithmetic operations such as multiplication, subtraction and square.

Translating the word problem into an algebraic expression, we have;

Doubling the unknown number, we would multiply by 2:

[tex]2n[/tex]

Subtracting 1 from the above and squaring, we have:

[tex](2n-1)^2 = 64\\\\2n-1=8\\\\2n =8+1\\\\2n=9\\\\n=\frac{9}{2}[/tex]

n = 4.5

Answer:

A) Kaden

B)Siaem

Step-by-step explanation:

the first number or part of a ratio is the numerator, and the second is the denominator, for part A 2 is the numerator and 3 is the denominator. the 30 is also the denominator so it would go on the bottom and x would be the numerator since we didn´t know the value of it. this also applies for Part B.

Answer:

X = 35

Step-by-step explanation:

5 + 100 = 7x + 30

5x + 100 - 100 = 7x + 30 - 100

5x = 7x - 70

5x - 7x = 7x - 70 - 7x

-2x = -70

-2x/-2 = -70/-2

x = 35

Answer:2

20/10=2/1=2

Step-by-step explanation: Rise over run

find a point were you can measure the squares I used 30 to 50

count the squares going up;2 and each square represents 10 so that equals 20

count the square(s) over; 1 and each square equals 10 so that equals 10

20 over 10 reduced is 2 over 1 and if a fraction is over 1 then it is a whole.

Ok What is the Question?

Answer:

A. 34in

Step-by-step explanation:

If James completely covered a square poster board using 68.2 inches with an exponent of 2, the the total perimeter of the square will be;

P = 2(68.2) = 136.4in

Since the perimeter of a square is expressed as:

P = 4L

136.4 = 4L

L = 136.4/4

L = 34.1in

Hence the measurement of one side of the square poster is closest to 34in

Answer:

slope = 2

Step-by-step explanation:

-8 - -6 / -9 - -8 = 2

Answer:

[tex]\frac{2}{1}[/tex] which is just 2

Step-by-step explanation:

slope = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

So plug the numbers in, now it should look like [tex]\frac{-6 - (-8)}{-8 - (-9)}[/tex]

-6 - (-8) = 2

-8 - (-9) = 1

So the slope is [tex]\frac{2}{1}[/tex]
