Answer:

Step-by-step explanation:

1. Move circle with center X, 2 units to the right and 8 units down to produce circle with radius 6 and center at the origin

2. Dilate this circle with a factor of 1/2 (or compress this circle with a factor of 2) to produce a circle with radius 3

3. Now move this circle 4 units to the right and 2 units up to produce circle Y.

CircleX can be transformed into circle Y by translations and a dilation, therefore the two circles are similar

Identify an equation in point-slope form for the line perpendicular to y = –4x – 1 that passes through (–2, 7).

Harlamova29_29 [7]

To get a perpendicular line, your slopes will equal -1 when multiplied...this means if we multiply - 4 x (1/4), we get out slope to use for the next step.

Y - Y1 = M(X - X1) passes through (-2, 7)
Y - 7 = 1/4(X - (-2))
Y - 7 = 1/4(X + 2)
Y - 7 = 1/4X + 1/2
+7 + 7
Y = 1/4X + 7.5

Rename the number to 120,000 ten thousand

Ray Of Light [21]

120,000 renamed to ten thousand (10,000) is twelve ten thousand. Ten thousand in number form is 10,000. When you divide 120,000 (one hundred and twenty thousand) by 10,000 (ten thousand) you get 12. 120,000 (one hundred and twenty thousand) /10,000 (ten thousand) = 12. So there are twelve ten thousands in 120,000.

Determine which system of equation has (-3,19) and (4,-23) as a solution?

grandymaker [24]

Answer:

y=6x+1

Step-by-step explanation:

First you must find the slope of the two points...

$\frac{4--3}{-23-19}$ which then would equal 6

Then you take the slope and put into point-slope form

(y-y1)=m(x-x1)...take one of the points that is given and plug it into this formula.

so I used (-3,19).

(y-19)=6(x--3)

I would then get y-19=6x+18

Add 19 to both sides and you will get y=6x+1

After breaking your penny bank, you notice that you have $4.87 in quarters ($0.25), dimes ($0.10), nickels ($0.05), and pennies

ira [324]

Answer: Option 'c' is correct.

Step-by-step explanation:

Let the number of dimes be 'x'.

Let the number of nickels be ' $\dfrac{3}{2}x$ '.

Let the number of pennies be $\dfrac{3}{2}\times 2x=3x$

Let the number of quarters be '3x-34'.

As we know that

1 quarter = $0.25

1 dime = $0.10

1 nickel = $0.05

1 penny = $0.01

According to question, we get that

$0.10x+0.05\times \dfrac{3x}{2}+0.01\times 3x+0.25(3x-34)=4.87\\\\0.10x+0.075x+0.03x+0.75x-8.5=4.87\\\\\\0.955x=4.87+8.5\\\\0.955x=13.37\\\\x=\dfrac{13.37}{0.955}\\\\x=14$

So, the number of pennies is given by

$3x=3\times 14=42$

Hence, Option 'c' is correct.
