Answer: A

Step-by-step explanation:

The parabola has an open hole at x=3 and the line has a closed hole at x=3, so there should be $x < 3$ for the parabola and $x \geq 3$ for the line.

This eliminates all the options except for A.

What is the interest rate if the principal is $25,000, the interest is $10,875, and the time is 15 years?

mel-nik [20]

Answer:

interest rate = 2.9%

Step-by-step explanation:

the principal is $25,000, the interest is $10,875

Number of years = 15

We use simple interest formula

I = P*r*t

Where I is the interest amount=10,875

P is the principal amount= 25000

r is the interest rate = r

t is the number of years = 15

Plug in all the value in the formula

I = P*r*t

10875 = 25000 * r * 15

10875 = 375000 * r

Divide both sides by 375000

r=0.029

We always write rate of interest in percentage so we multiply by 100

0.029 * 100= 2.9%

So interest rate = 2.9%

4(x + 3) = 6-x what is the answer I need help please

Amanda [17]

4(x + 3) = 6 - x

First, expand to remove parentheses.
$4x + 12 = 6 - x$
Second, subtract '6' from both sides.
$4x + 12 - 6 = -x$
Third, subtract '12 - 6' to get 6.
$4x + 6 = -x$
Fourth, subtract '4x' from both sides.
$6 = -x - 4x$
Fifth, since 'x' can be referred to as '1', add it to '4x' to get '-5x'.
$6 = -5x$
Sixth, divide both sides by '-5'.
$\frac{6}{-5} =x$
Seventh, change the whole fraction into a negative.
$-\frac{6}{5} =x$
Eighth, switch your sides.
$x = -\frac{6}{5}$

Answer as fraction: $-\frac{6}{5}$
Answer as decimal: -1.2

What is the relationship between the 1s in 911,147,835

lukranit [14]

Find the relationship of 1’s in the given number.
given number = 911 147 835
before we are going to determine the relationship of 1’s , let’s give each digit’s place value.
9 hundred million
1 ten million
1 million
1 hundred thousand
4 ten thousands
7 thousands
8 hundreds
3 – tens
5 - ones
Now, we have the 1 ten million, 1 million, and 1 hundred thousand
What is the relationship of the 3.
=> we’ll those 1’s are 10 times greater with each other
=> 1 million is 10 times greater than 1 hundred thousands
=> 100 000 x 10 = 1 000 000
=> 1 ten million is ten times greater than 1 million
=> 1 000 000 x 10 = 10 000 000
