solve for x. plz need help​

Answer:

click the points (0,4) and (1,5)

Step-by-step explanation:

y = x+4

if x  =  0 then

y = 0+4

so y = 4

0 , 4

then if x = 1

y = 1+ 4

so y = 5

1 , 5

Answer:

x = -3

Step-by-step explanation:

Answer:

x= -3

Step-by-step explanation:

2(3x+4)=4x+2 (expand what's in the parentheses)

6x+8=4x+2 (subtract 8)

6x=4x-6 (subtract 4x)

2x = -6 (divide both sides by 2)

x= -3

3×3×3=27

Answer:

the answer is 100% 3

Step-by-step explanation:

Answer:

34/40

Step-by-step explanation:

85/100 cross multiply x/40

100x/100=3400/100

x=3400/100

634.4   so the standard form is 600  + 30  + 4  + 0.4

Answer:

634.4 or 6.344*10^2

Step-by-step explanation:

When you're being asked to write an expression in standard form, the question probably wants you to simplify the expression or write it in scientific notation

Usually, in lower levels, you would simplify the expression, in which case you would multiply 6.1 by 104 using either a calculator (if you're allowed) or on paper to get 634.4

If you think your teacher wants you to use scientific notation, you would want to write your expression as a number under 10 multiplied by a power of 10. For example, if you were looking to write 6*8 in scientific notation/standard form, you would simplify for a product of 48, and turn that into 4.8*10. In your problem, you can multiply 6.1*104, and write your product of 634.4 as 6.344*10^2

please tell me if there are any mistakes in my answer, if i wrote anything poorly, or if anything is hard to understand, i hope this helps!!

Answer:

a) The polynomial is equivalent to [tex]A = (x-15)^{2}[/tex], and the side length of the playground is [tex]x -15[/tex] feet.

b) The perimeter of the playground, measured in feet, is [tex]p = 4\cdot (x-15)[/tex].

Step-by-step explanation:

a) By Geometry, we know that area of the square is equal to the square of the side length. If [tex]A = x^{2}-30\cdot x +225[/tex] is the area of the square, then must be a perfect square trinomial, that is:

[tex](x-a)^{2} = x^{2}-2\cdot a\cdot x + a^{2}[/tex] (1)

Then, we must observe the following properties:

[tex]-2\cdot a = -30[/tex] (2)

[tex]a = 15[/tex]

[tex]a^{2} = 225[/tex] (3)

[tex]a = 15[/tex]

Therefore, the polynomial is equivalent to [tex]A = (x-15)^{2}[/tex], and the side length of the playground is [tex]x -15[/tex] feet.

b) The perimeter of a square equals four times the side length. That is:

[tex]p = 4\cdot (x-15)[/tex]

The perimeter of the playground, measured in feet, is [tex]p = 4\cdot (x-15)[/tex].

The polynomial that represents the side length is x - 15, and the perimeter of the playground is 4x - 60

The expression of the area is given as:

[tex]A = x^2 - 30x + 225[/tex]

Expand the expression

[tex]A = x^2 - 15x - 15x + 225\\[/tex]

Factorize

[tex]A= (x - 15)^2[/tex]

The area of a square is:

[tex]A = l^2[/tex]

Where l represents the side length.

So, we have:

[tex]l = x - 15[/tex]

The perimeter is then calculated as:

[tex]P = 4l = 4*( x - 15)[/tex]

[tex]P = 4x - 60[/tex]

Hence, the perimeter of the playground is 4x - 60

Answer:Percentage of discount tickets =48%

Step-by-step explanation:

Percentage of discount tickets = Number of discount tickets / total num ber of tickets  x 100

But Total number of tickets  = Discount tickets + full-price tickets

=  276 +299

 = 575 tickets

Percentage of discount tickets = 276/575  x 100/1

Answer:

Area of the parallelogram = 21.6 cm²

Step-by-step explanation:

Area of a parallelogram = Base × Height of the side parallel to the base

By using ruler,

Base = 4.8 cm

Height of parallelogram = 4.5 cm

Area of the parallelogram = 4.8 × 4.5

                                           = 21.6 cm²

Step-by-step explanation:

Answer:

(-5, -1), does not belong to the relation y = -x + 4

Step-by-step explanation:

From the question, we have;

The given ordered pair having a relation = (-5, -1)

The given relation, y = -x + 4

From the given relation, we get;

When y = -1

-1 = -x + 4

∴ -x = -1 - 4 = -5

x = 5

Similarly, when x = -5, we get;

y = -x + 4 = -(-5) + 4 = 5 + 4 = 9

y = 9

Therefore, (-5, -1), does not belong to the relation y = -x + 4 but (-5, -1), belongs to the relation y = x + 4

Answer:

$93.6

Step-by-step explanation:

The original price if this show is to be sold at $156

But the question tells us that everything is being sold with a 40% off.

So we should get 40% of 156

= 0.40 * 156

= $62.4

So this shoe would have it's new price to be $(156 - 62.4) = $93.6

So in conclusion given a 40 percent off, the sales price if the shoe would be $93.6

Answer:

2 + 3 = 5

5 - 2 = 3

3.4 + 7.1 = 10.5

7 + 8 = 15

15 - 7 = 8

9/5 + 3/2 = 33/10

33/10 - 3/2 = 9/5
