Help Its Urgent :( Ill Mark Brainliest

Answers

Answer 1

Answer:

x = 4

x = 10

Step-by-step explanation:

x^2 -14x + 40 = 0 ----> factor form

(x - 10)(x - 4) = 0 ---> separate equations

x - 10 = 0 ---> add 10 on both sides

x = 10

x - 4 = 0 ---> add 4 on both sides

x = 4

Answer 2

Answer:

small x= 4

large x= 10

Step-by-step explanation:

hello there!

x^2-14x+40=0

x^2-(10+4)x+40=0

x^2-10x-4x+40=0

pick out the common one!

x(x-10)-4(x-10)=0

(x-10)(x-4)=0

now;

x-10=0

x=10(which is large x)

again:

x-4=0

x=4( which is small x)

hope it helps.. thank u!

Find the slope please!

Answers

Answer:  1/2

Explanation:

The two points (0,0) and (2,1) are on the line. Apply the slope formula to them to get the following

m = (y2-y1)/(x2-x1)

m = (1-0)/(2-0)

m = 1/2

This indicates that each time you go up 1 unit, you must move to the right 2 units.

Slope = rise/run = 1/2

rise = 1, run = 2

4x^2-y^2 how do you factorize this? with steps pls:)

Answers

Answer:  (2x-y)(2x+y)

===========================================

Work Shown:

4x^2 - y^2

(2x)^2 - (y)^2

(2x-y)(2x+y)

When going from the second step to the third step, I used the difference of squares rule. That rule is a^2-b^2 = (a-b)(a+b). In this case, a = 2x and b = y.

Side note: (2x-y)(2x+y) is the same as (2x+y)(2x-y). We can multiply in any order.

Step-by-step explanation:

It seems a factoring problem:

-30 - js - 6s - 5j = (-30 - 6s) - (js + 5j) = -6(s + 5) - j(s + 5) = (s + 5)( -6 - j) = -(s + 5)(j + 6)

Substitution would be the best method for solving which system?
O x = 6
2x - 3y = 8
3x - 2y = 18
4x + 5y = 60
O x + y = 7
x - 4y = 12
O y = 2x
x + y = 28

Answers

Answer:

The last one

Step-by-step explanation:

Because it tells you what y is

Answer:

Assuming its asking which is the easiest one to use substitution its the last one: y= 2x : x + y = 28

Step-by-step explanation:

Because y and x are already one opposite sides you can substitute y in the 2nd equation with 2x. So you'll get 3x = 28 so x = 9.333333334. Then you plug your answer for x in the original equation to get y = 18.666666667

Mrs. Davis is building a storage shed that is 12 feet long and 8 feet wide. Construct a scale drawing of the shed. Use a scale of 1/2 inch = 8 feet

Answers

Answer:

3/4 inch by 1/2 inch (length - width)

Step-by-step explanation:

If 1/2 inch equals 8 feet on the scale drawing, this means that 1/4 inch on the scale drawing equals 4 feet, by dividing 2 on both sides.

The storage shed is 12 feet long, and 4 feet on the scale drawing equal 1/4 inch. By multiplying the scale of 1/4 inch = 4 feet by 3 on both sides, we get 3/4 inch = 12 feet. This means that the length of the storage shed can be represented by 3/4 inch.

Since 1/2 inch equals 8 feet and the width of the storage shed is 8 feet, the width can be represented by 1/2 inch on the scale drawing.

what is -2x + x?

Answers

Answer:

-x

Step-by-step explanation:

Note that when there is a standalone variable (such as the x in this example), it typically actually means 1x. (If it is -x, it will be -1x.) However, you do not write 1 in front, as it is presumed.

Subtract the coefficient of each terms:

1x - 2x = -1x

-x is your simplified form.

Answer is -x

• If a term doesn’t have a coefficient is considered that the coefficient is 1
-2x + 1x
• collect like terms by calculating the sum of the coefficients
(-2 + 1)x
• Write the sum
-1x
• The coefficient negativeone doesn’t have to be written but the sign remains
-x
