Factorize using suitable identity
a²-(b-c)²​

Answers

Answer 1

Step-by-step explanation:

We have,

a ^2 −(b−c) ^2

Since, x ^2 −y ^2 =(x+y)(x−y)

Thus,

⇒[a−(b−c)][a+(b−c)]

⇒(a−b+c)(a+b−c)

Hence, this is the answer.

I hope it's helpful!

A line with a slope of 2 passes through the point (1,9). What is its equation in
slope-Intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
y = x + O

Answers

In point-slope form, our equation would be y - 9 = 2(x - 1). Expanding, we get y - 9 = 2x - 2. Solving for y, we obtain the form of the equation as shown in the problem: y = 2x + 7.

So, the numbers that would go in the blanks would be 2 and 7, respectively.

The slope intercept form of the line that passes through the point (1, 9) and has the slope 2 is y = 2x + 7.

What is slope intercept form of the line?

The slope intercept form of the line is:

y - y₁ = m (x - x₁)

Given that the point that the line passes through is: (1, 9)

The slope of the line is: m = 2

Substitute the values in the equation, we get;

y - 9 = 2 ( x - 1)

y - 9 = 2x - 2

y = 2x + 7

Therefore, we get that, the slope intercept form of the line that passes through the point (1, 9) and has the slope 2 is y = 2x + 7.

So, the numbers that would be in the blanks would be 2 and 7, respectively.

When solving the inequality y< -2x+1 by graphing , the solution region will be

Answers

Answer:

We want to find the solution region for:

y < -2*x + 1

To find the region, the steps are:

Write the inequality as an equation like:

y = -2*x + 1

Let's graph this line.

Because we have the symbol "<", the line will be a dashed line. This is because y is strictly smaller than the line, so the points of the line itself are not solutions.

And our inequality is:

y < -2*x + 1

So y is smaller than the line, then the shaded region is all the region below the line.

The graph of this inequality is shown below.

what's 875,098 to the nearest 100 rounded?

Answers

Answer:

the answer to the problem is 875,100

Answer:

875,100

Step-by-step explanation:

When we round to a particular place, we will use a few simple rules.

First, let's highlight the place value we're rounding to.

875,098

Next, we look at the number behind the highlighted number, in this case the tens place. If the number is less than 5, the highlighted place value will stay the same. If the number is 5 or above, the highlighted place value increases by 1. In this case, we round 0 up to 1, since there was a 9 in the tens place. We then add zeros for the tens and ones place, since we rounded out of those.

when p = 4, q = 30

put this as a proportion so that this is one sidelook at what i did

x = 75

here i used x as q, therefore whatever x is, will be q

Mrs.Evans has 13 pictures to hang on a wall.Is there any way she can arrange the pictures other than 1x13 13x1 so that she can have the same number of pictures in each row? Tell whether 13 is a composite or prime number.Explain.

Answers

Answer:

Step-by-step explanation:

A prime number is a positive integer that only has a factor of one and itself. Factors are the numbers we multiply together to get another number.

Example: 11 is a prime number. To get 11, we can only multiply 1x11.

A composite number is a positive integer that has factors other than one and itself.

Example: 12 is a composite number. To get 12, you can multiply together 1x12, 2x6, and 3x4. 1, 2, 3, 4, 6, and 12 are all factors of 12.

In the problem you are trying to solve, Mrs. Evans wants to hang 13 pictures with the same number of pictures in each row. Find all of the factors of 13: 1, 13. Those are the only numbers we can multiply together to get 13. Since its factors are only 1 and itself, 13 is a prime number. Because 13 is a prime number, there are no other possible ways she can arrange her pictures into rows with the same number of pictures in each.

Find an expression which represents the difference when (2 + 4y) is subtracted
from (-8x + 3y) in simplest terms.

Answers

Answer:

-8x - y - 2

Step-by-step explanation:

(-8x + 3y) - (2 + 4y)

Change this to addition, but change the signs in the second parentheses:

(-8x + 3y) + (-2 - 4y)

Add like terms:

-8x - y - 2

So, the difference is -8x - y - 2

(-8x + 3y) - (2 + 4y)

= -8x + 3y - 2 - 4y

= -8x + 3y - 4y - 2

= -8x - y - 2

A line plot with Kelly's ribbon lengths is shown .she adds two more ribbons so that the total length of ribbon is 200 inches . What are two possible lengths of ribbon, in inches , that Kelly could have added

Answers

Answer: (I changed it back to fraction form instead of decimal because it seems that is how you are doing it)

Two possible lengths of ribbon (In inches) are 25 and 133  3/4

Step-by-step explanation:

Okay, so- First, You need to find out how much ribbon is there before the two additional ones are added. Like this:

12 + 14  2/4 + 14  3/4 = 41  1/4

Next, subtract that amount from 200 to get the number of inches of ribbon that are needed to get 200 inches of ribbon. Like this:

(I changed it to a decimal to make it easier, so don't mind that)

200 - 41.25 = 158.75

So, 158.75 inches of ribbon are needed to get 200 inches. You can subtract any number less than 158.75 from that to get two seperate ribbon measurements.

(This might sound confusing so here)

For example:

158.75 - 25 = 133.75 (The bolded numbers are the two measurements)

158.75 - 65 = 93.75

So, Two possible lengths (in inches) of ribbon that kelly could have added are "25" and "133.75 "

Two possible lengths (in inches) of ribbon that kelly could have added are also "65" and "93.75"
