Oscar has a $2,500 balance on his credit card that accumulates 14.5% interest compounded annually. Which of the following could be used to find the balance on the card after 5 years?

Answer:

n = 54

Step-by-step explanation:

[tex]\frac{2}{12}=\frac{9}{n}\\[/tex]

Cross products,

2 * n = 9 *12

 2n = 108

Divide both sides by 2

[tex]n = \frac{108}{2}\\[/tex]

n = 54

Answer:

no C

(25×4)+15

because out of 25 students each students brought 4 stamps which means 25×4 and their teacher brought 15 which is added .

Answer:

C

Step-by-step explanation:

there are 25 students and they EACH brought 4. Each means you multiply. so we have 25x4. then Mr. Miller brought 15 more stamps so we need to add that to the equation. so we have (25x4) because that is separate from the 15.

(25x4)+15

Answer:

z is a variable so it can be any number.

z=-3

if you do -8 times -3 that equals 24.

the answer is -3

Step-by-step explanation:

Answer:

z stands for 3.

Step-by-step explanation:

First, subtract 12 from both sides.

-8z + 12 - 12 = -12 - 12

-8z = -24

Next, let's put brackets [] between both numbers. Any number inside of these becomes positive.

[-8z] = [-24]

8z = 24

Finally, let's divide doth sides by 8!

8z/8 = 24/8

z = 3

Answer:

y=4  x=2

Step-by-step explanation:

y=2x ⇒ I

y=10x-16 ⇒ II

y/2=2x/2

x=y/2 OR 1/2(y)

substitute I in II

y=10(y/2)-16

y=5y-16

SWAP -16 AND y

5y-y=16

Answer:

x=2.33

Step-by-step explanation:

6+3x=12x-15​

-9x=-21

x=21/9

x=2.33

Answer:

x = 2.33

Step-by-step explanation:

6 + 3x = 12x - 15​

6 = 9x -15

21 = 9x

x = 2.33

Answer:

y=3

Step-by-step explanation:

30y+6/3=23

6(5y+1)/3=32

2(5y+1)=32

5y+1=32/2

32/2=16

5y=16-1

16-1=15

y=15/5

y=3

Answer:

For example, the conjugate of 0 + √3 is 0 - √3, the conjugate of -√3 is √3, and the conjugate of 2 - 5√3 is 2 + 5√3.

Step-by-step explanation:

The complex conjugate of the root x = 3i will be x = -3i.

The complex conjugate of a complex number is the number that has equal real and imaginary parts that are opposite in sign but equal in magnitude.

A given complex function is x = 3i

As we know that the complex conjugate function is one in which the imaginary part of the function becomes negative.

The complex conjugate function will be:-

x = -3i

Therefore the complex conjugate of the root x = 3i will be x = -3i.

Answer:

B

Step-by-step explanation:

Pythagorean's Theorem states that a² + b² = c² for any right triangle.

7² + 24² = 25²

This statement is true, as both sides equal 625, therefore the correct answer is B.

Answer:

6 students

Step-by-step explanation:

Given data

Base charge= $40

charge per student = $30

We are told that for s number of student the tutor charged 220

The expression for the tutor's charges is given as

y= 40+30s

Therefore for y= 220, let us find s, the number of students

220=40+30s

220-40= 30s

180=30s

divide both sides by 30

s= 180/30

s= 6

Hence there are 6 students

Answer:

(-4,9)

Step-by-step explanation:

substitute the given value for y into the first equation

x-5(-2x+1)=-49

distribute

x+10x-5=-49

add like terms

11x-5=-49

add 5 to both sides

11x=-44

divide both sides by 11

x=-4

now plug x into into the second equation

y=-2(-4)+1

y=8+1

add like terms

y=9

Answer:

should be reflection

Step-by-step explanation:

bc a translation would just move it and rotation and dilation wouldn't work either

The single transformation was applied to triangle A to get triangle B is a reflection, in which A is reflected around the y-axis.

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point.

Given:

The triangles A and B are shown in the given figure,

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original,

Rotation is the process of going around a center.

A shape is translated when it is moved up, down, left, or right without turning. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes.

Thus, triangle A is reflected as B.

Answer: x= 4.5, y=3.6, z=6.5

Step-by-step explanation:

To find : x, y and z.

First label the triangle as A,B,C and D (as in the picture below).

ΔABC , ΔACD and ΔABD both are right triangles.

In ΔABC ,

[tex]y^2=3^2+2^2[/tex]        [By Pythagoras theorem]

[tex]\Rightarrow\ y^2=13\\\\\Rightarrow\ y=\sqrt{13}\approx3.6[/tex]

In ΔACD ,

[tex]AD^2=3^2+x^2\\\\\Rightarrow\ AC^2=9+x^2 \ \ ...(i)[/tex]        [By Pythagoras theorem]

In ΔABC ,

[tex]y^2+AC^2=(2+x)^2\\\\\Rightarrow\ AC^2=(2+x)^2-y^2\ \ ...(ii)[/tex]

From (i) and (ii), we get

[tex]9+x^2=(2+x)^2-y^2\\\\\Rightarrow\ 9+x^2=4+x^2+4x-(3.6)^2\\\\\Rightarrow\ 9=4+4x-12.96\\\\\Rightarrow\ 4x=9-4+12.96\\\\\Rightarrow 4x= 17.96\\\\\Rightarrow\ x=\dfrac{17.96}{4}\\\\\Rightarrow\ x=4.49\approx4.5[/tex]

Z = 2+x= 2+4.5 =6.5

Hence, x= 4.5, y=3.6, z=6.5
