I had trouble understanding algebra and now I am in geometry so If you can help me understand both that will be good. I have thi

diamong [38]

Start by completely ignoring the paralelagram.

Let's choose the top triangle as our starter.

To get the top triangle to the position of the bottom triangle, you must translate it.

First, find how many units the first triangle must move down to reach the same level as the bottom triangle, (i'll let you figure it out bu numbering this as a question) 1.<u> </u>

Next, your first triangle should need to move left to reach the position of the second triangle. How many units left does the first triangle need to move?

2.<u> </u>

<u>You moved the first triangle *Blank* units down and *Blank* units left.</u>

Lastly, you need to look at your paralelagram.

Take the same movements you did with the two triangles and transfer them to the nessacary point of the paralelagram.

<em><u>If you need and extra help, or need more explanation, ask in the comments section. I also recomend that you tell me what you got as your answers to one and two so that you can make sure you got the answer correct.</u></em>

From delta math:<br> Subtract -2x^2 + 3x - 9 from 8x^2 + 10x - 10

Leto [7]

Answer:

$10x^2 + 7x - 1$

Step-by-step explanation:

Step 1: Build the expression in numerical form.

$(8x^2 +10x - 10) - (-2x^2 + 3x - 9)$

Step 2: Distribute the negative sign.

$8x^2 +10x -10 + (-1)(-2x^2) + (-1)(3x) + (-1)(-9)$
$8x^2 + 10x - 10 + 2x^2 + (-3x) + 9$

Step 3: Combine like terms.

$(8x^2 +2x^2) + (10x -3x) + (-10+9)$
$10x^2 +7x -1$

Therefore, the answer is $10x^2 + 7x -1$ .

Frank is lending $1,000 to Sarah for two years. Frank and Sarah agree that Frank should earn a real return of 4 percent per year

Montano1993 [528]

Answer:

nominal rate of interest is 31.7 %

Step-by-step explanation:

given data

payment = $1000

time = 2 year

rate = 4%

CPI = 100

CPI final yer = 127.7

to find out

nominal rate of interest

solution

we know nominal rate of interest formula that is

nominal rate of interest = real interest rate + inflation rate .........1

so here inflation rate is express as

inflation rate = ( CPI final year - CPI ) / CPI × 100 ...........2

put here value

inflation rate = ( 127.7 - 100 ) / 100 × 100

inflation rate is 27.7 %

so from equation 1

nominal rate of interest = real interest rate + inflation rate

nominal rate of interest = 4% + 27.7%

nominal rate of interest is 31.7 %
