Answer:

The appraiser said that the condo is currently worth $202,470 and it's 2% higher than the condo was worth when Mr. Duncan bought it several years ago. To find the value of the condo when he bought it, we need to subtract 2% of the current value from the current value.

We can find 2% of the current value by multiplying it by 0.02:

$202,470 x 0.02 = $4,049.4

To find the value of the condo when he bought it, we need to subtract $4,049.4 from the current value:

$202,470 - $4,049.4 = $198,420.6

Therefore, the value of the condo when Mr. Duncan bought it was $198,420.6

Answer:

335.115

Step-by-step explanation:

First you find the area of the circles to do that you do pi times radius squared

For the top square do 3.14(pi)time 3²=28.26

For the middle square do 3.14 times 4.5²=63.585

For the bottom square do 3.14 times 6²=113.04

Now find the area of the entire thing do 18×12+9+6+3=18×30=540

Finally do 540-the area of the squares 28.26-63.585-113.04= 335.115

So the shaded region is 335.115

Hope this helps and have a great day!

Answer:

The equation is: \(5c-2=9\)

Step-by-step explanation:

Since 2 less than the product of 5 and a number c is equal to 9, it follows:

Answer: 189.1 astronomical units

Step-by-step explanation:

The formula for the circumference of a circle is the C=dπ (circumference = diameter times pi)

the diameter is just the radius times 2

30.1 · 2 = 60.2

now multiply that by pi to find the circumference

60.2 · π = 189.1 astronomical units

Answer:

Step-by-step explanation:

you add up the numbers for red green and purple. Then you add all of the numbers together separately. Then you take the number you got after you added red green and purple and divide it by the number you got when you added them all together. Then you round your decimal to the nearest hundredth.

Answer:

9

Step-by-step explanation:

First add all the fractions so I will equal 6 \(\frac{3}{4}\)

steps : make it so that all fractions have the same denominator so we will be adding 10/4 + 8/4 + 2/4+ 7/4 which is equal to 27/4 and if you simplify that you get 6 \(\frac{3}{4}\)

Then divide by 3/4 which is 9

so your answer is 9

Answer:

A, D,E

Step-by-step explanation:

They are all divisible by 5

Answer:

a) Missing y-values
x = - 2    ==>   y = 5

x = - 1     ==>   y = 2

x =   1    ==>    y = 2

x =   3   ==>    y  = 10

b) Values of x for y = 4:
x = 1.7 and x = -1.7

Step-by-step explanation:

Given the quadratic function,
y = x² + 1

part a)

to find the y-value for a specific x, just plug in that value of x into the right side and simplify

There are four missing values for

The x values and the corresponding y values are
x = - 2    ==>   y =  (-2)² + 1   =  4 + 1 = 5

x = - 1     ==>   y  =  (-1)²  + 1  =  1 + 1 = 2

x =   1    ==>    y  =   (1)²  + 1  = 1 + 1  = 2

x =   3   ==>    y   =  (3)²  + 1  = 9 + 1 = 10

part b)

The graph has each unit on the grid for the x-axis = 0.5
and
each unit on the grid for the  y-axis  = 2

I got this by seeing that between x = 0 and x = 1 there are two units

the value of y at x = -1 or x = 1 is only one vertical unit on the grid and since y = 2 for these values of x, each vertical unit must be 2

Therefore look at the value of y = 4 (which should be two vertical units) on the graph. You can also draw a horizontal line parallel to the x axis at 2 units from the x-axis

It appears that on the positive x-axis for y = 4, x is about halfway between 1.5 and 2 so I would estimate it at 1.75

On the negative x-axis, at y = 4, x is about halfway between -1.5 and -2 so it would be -1.75

One thing to note about quadratic functions is that you get the same value of y for x and -x

So at y = 4, the two possible values of x are
x = 1.75 and x = -1.75

which when using one decimal place will round to 1.7 and 1;75

I am rounding down rather than rounding up since the x value appears be less than 1.75

Mathematically we can solve for x at y = 4 by plugging in values
y = 4 = x² + 1

x² + 1 = 4

x² = 4 - 1 = 3

x =±√3 = ±1.732

which when rounded to 1 decimal place becomes
x = 1.7 and x = -1.7

Answer:

Step-by-step explanation:

a) y = (-2)² + 1 = 5

y = (-1)² + 1 = 2

y = (1)² + 1 = 2

y = (3)² + 1 = 10

b)  4 = x² + 1

x² = 4 - 1 = 3

x = ±√3 = ±1.7

Answer:

Step-by-step explanation:

Yellow block closest side and farthest side: 2x1=2 2x2=4

Yellow block right and left side: 1x1=1 1x2=2

Yellow block bottom: 2x1=2

Yellow block top: 2x1=2

Purple block closest side and farthest side: 5x2=10 10x2=20

Purple block right and left side: 2x3=6 6x2=12

Purple block bottom: 5x3=15

Purple block top: 5x3=15 15-2=13

2+2+2+1+1+13+10+10+6+6+15= 68

The overlap effects the calculation of the surface area because the bottom of the yellow block and a part of the purple block overlaps making it so that you would count it two times instead of the area that is visible.

I like to think of it as spray painting the blocks and seeing where the paint sprays.

Answer:

Reflecting over y = -1 line:

A'(8, -10)

B'(10, -8)

C'(2, -4)

Reflecting over y = -7 line:

A''(8, -4)

B'(10, -6)

C''(2, -10)

Step-by-step explanation:

Reflect the given preimage over y=−1 followed

by y=−7. Find the new coordinates. What one transformation is this double reflection the same as? (Note: when you are reflecting over a y= line, the x-values of the preimage will remain the same and you will be changing the y-values)

The coordinates of the preimage are:

A(8,8)

B(10,6)

C(2,2)

Answer: Reflecting over y = -1:

If a point is reflected over a y line, the x values remain the same while the y values change.

For point A(8, 8): The y distance between the y = - 1 line and point A is 9 units. (8- (-1)). If point A is reflected, the y value would be 9 units below the y = -1 line, i.e the new y coordinate would be at -10 (-1-9)

The new coordinate is at A'(8, -10)

For point B(10, 6): The y distance between the y = - 1 line and point B is 7 units. (6- (-1)). If point B is reflected, the y value would be 7 units below the y = -1 line, i.e the new y coordinate would be at -8 (-1-7)

The new coordinate is at B'(10, -8)

For point C(2, 2): The y distance between the y = - 1 line and point C is 3 units. (2- (-1)). If point C is reflected, the y value would be 3 units below the y = -1 line, i.e the new y coordinate would be at -4 (-1-3)

The new coordinate is at C'(2, -4)

Reflecting over y = -7 line:

For point A'(8, -10): The y distance between the y = - 7 line and point A' is 3 units. (-7- (-10)). If point A' is reflected, the y value would be 3 units above the y = -7 line, i.e the new y coordinate would be at -4 (-7+3)

The new coordinate is at A''(8, -4)

For point B'(10, -8): The y distance between the y = - 7 line and point B' is 1 units. (-7- (-8)). If point B' is reflected, the y value would be 1 units above the y = -7 line, i.e the new y coordinate would be at -6 (-7 + 1)

The new coordinate is at B'(10, -6)

For point C'(2, -4): The y distance between the y = - 7 line and point C' is 3 units. (-4- (-7)). If point C' is reflected, the y value would be 3 units below the y = -7 line, i.e the new y coordinate would be at -10 (-7-3)

The new coordinate is at C''(2, -10)

We can also see that h= −7−(−1)=−6. We know that two reflections is the same as a translation of 2h  units down. So 2(−6) is a translation of −12 units down.

Answer:

D should be the correct answer

Step-by-step explanation:

Answer:

\(5x^2 - x - 17\)

Step-by-step explanation:

Distribute the terms inside the first set of parentheses:

\((2x - 7)(x + 3) = 2x^2 + 6x - 7x - 21\)

Combine like terms:

\(= 2x^2 - x - 21\)

Simplify by adding the second part:

\(2x^2 - x - 21 - (-3x^2 - 4)\)

Subtracting a negative is the same as adding the positive equivalent:

\(= 2x^2 - x - 21 + 3x^2 + 4\)

Combine like terms:

\(= 5x^2 - x - 17\)

(2x-7)(x+3)-(-3x^[2] - 4)

====

5x^[2] -x -17

To begin simplifying this expression, we will foil the first half of it:

(2x-7)(x+3)

2x*x + 2x*3 - 7*x - 7*3

2x^[2] + 6x - 7x - 21

With this, we combine like terms:

2x^[2]-x-21

We now have

2x^[2]-x-21-(-3x^[2]-4)

We can now do the binomial distribution in the second half of the expression. Remember, the - sign in front of the parentheses means we are negating everything inside. In other words, we are multiplying -1 by everything inside the parentheses. Following this:

-(-3x^[2]-4) becomes

-1*-3x^[2] + -1*-4 = 3x^[2]+4

We have now simplified the first and second half of our expression, so we have:

2x^[2]-x-21+3x^[2]+4

And combining like terms we get

2x^[2]+3x^[2]-x-21+4 =

5x^[2] -x -17

We can use the quadratic expression to determine if the trinomial can be factored evenly, but it cannot so we have our final simplifed expression!
