PLEASE HELP! it’s urgent!!

Answer:

The base is 12ft

Step-by-step explanation:

2x² + 8x - 1 = 0

2(x + 2)² - 9 = 0

2(x + 2)² = 9

(x + 2)² = 4.5

x = √4.5 - 2 or x = -√4.5 - 2

x = 0.12 or x = -4.12.

Answer:

[tex]perimeter = 2(l + w) \\ but \: length = 40 \times width \\ perimeter = 2(40w + w) \\ p = 2(41w) \\ 320 = 2(41w) \\ w = \frac{320}{(2 \times 41)} \\ w = 3.902 \: yards \\ length = 40 \times w \\ = 40 \times 3.902 \\ l = 156.08 \: yards[/tex]

9514 1404 393

Answer:

Step-by-step explanation:

Let w represent the width of the field. Then the length is (w+40), and the perimeter is ...

  P = 2(L +W)

  320 = 2((w+40) +w) . . . . fill in values

  160 = 2W +40 . . . . . . . . . divide by 2, collect terms

  80 = w +20 . . . . . . . . . . .  divide by 2

  60 = w . . . . . . . . subtract 20

  w+40 = 100

The length is 100 yards; the width is 60 yards.

Answer:

6x 9/4-3         reduce the number with the gratest common factor 2

3 x 9/2-3             when dealing with fraction just multiply denominator

27/2-3                 the denominator will stay the same always

Answer:

Slope: -5/8

y intercept: (0,1)

Step-by-step explanation:

The slope of the line will be {m} = -5/8 and the y - intercept will be 1.

Direct variation of a quantity {y} with respect quantity {x} means that the value of {y} increases as the the value of {x} increases. Mathematically -

y = Kx

K = y/x

where -

{K} is scale factor. It also tells by how many times is {y} greater than {x}.

Given is the equation of a straight line as -

5x + 8y = 8

We can rewrite the equation as -

5x + 8y = 8

8y = - 5x + 8

y = -(5/8)x + 1

So the slope will be -

m = -(5/8)

c = 1

Therefore, the slope of the line will be {m} = -5/8 and the y - intercept will be 1.

Step-by-step explanation:

Answer:

y = 9.5

Step-by-step explanation:

Express the ratios in fractional form, that is

[tex]\frac{1.5}{4}[/tex] = [tex]\frac{9}{2y+5}[/tex] ( cross- multiply )

1.5(2y + 5) = 36 ( divide both sides by 1.5 )

2y + 5 = 24 ( subtract 5 from both sides )

2y = 19 ( divide both sides by 2 )

y = [tex]\frac{19}{2}[/tex] = 9.5

Answer:

It is (9,-3) because x increased by 1 unit and y increased by 4 units.

Answer:

[tex](9,-3)[/tex]

Step-by-step explanation:

[tex](8,-7)[/tex]

If it moves right, add the value to the x-coordinate. If it moves left, subtract the value from the x-coordinate. In this case, because the point was translated 1 unit right, we add 1 to the x-coordinate 8.

[tex](9,-7)[/tex]

If it moves up, add the value to the y-coordinate. If it moves down, subtract the value from the y-coordinate. In this case, because the point was translated 4 units up, we add 4 to the y-coordinate.

Answer:

The function f(x) = -9.5 + 6 + x² is neither odd or even.

Step-by-step explanation:

We know that a function is termed as 'even' when

f(-x) = f(x) for all x

We know that a function is termed as 'odd' when

f(-x) = -f(x) for all x

Given the function

f(x) = -9.5x⁵ + 6 + x²

substitute x with -x

f(-x) = -9.5(-x)⁵ + 6 + (-x)²

as (-x)⁵ = -x⁵, so

f(-x) = -(-9.5x)⁵ + 6 + (-x)²

Apply exponent rule: (-a)ⁿ = aⁿ, if n is even

f(-x) = -(-9.5x)⁵ + 6 + x²

Apply rule: -(-a) = a

f(-x) = 9x⁵ + 6 + x²

As

f(-x) ≠ f(x) ≠ -f(x)

Therefore, the function f(x) = -9.5 + 6 + x² is neither odd or even.

Step-by-step explanation:

(3x-2y=-16)first put in standard form y=mx+b

(-2y=-3x-16) divide both sides by -2

y=3/2x+8

Answer:

C

Step-by-step explanation:

By opposite I'm going to assume they mean the perpindicular line

To do this you first need to convert the function into linear form

So we have 3x-2y=-16

and so we can add 2y and 16 to both sides to get

3x+16=2y

then divide by 2 to get

3/2x+8=y

This is our function in linear form but now we need the opposite by taking the negative reciprocal of the slope

This means our near equation is now -2/3x+8 while none of them give that as an option directly if you simplify C it will match

Answer:

75 + 3.5n ≤ 100

Step-by-step explanation:

Given that:

Total amount = $100

Cost of shoe = $75

Cost per socks = $3.50

n = number of socks pairs

Cost of shoe + (cost per pair of socks * number of socks) ≤ total amount

75 + (3.50 * n) ≤ 100

75 + 3.5n ≤ 100

Answer:

The number is -43.75.

Step-by-step explanation:

4x/5 - 11 = -46

4x/5 = -35

x = -43.75

Answer:

-43.75

Step-by-step explanation:

This is the answer because:

1) We know that 4/5 of a number has to equal -35 since -46 + 11 = -35.

2) 4/5x = -35 (solve for x): -35 ÷ 4/5 = -43.75

3) 4/5 x -43.75 = -35, I got this by solving for x (look at step 2)

Therefore, the answer is -43.75

Hope this helps! :D

Answer:

  x = 4

Step-by-step explanation:

The two marked angles are supplementary when the lines are parallel.

  (20x +5)° +(24x -1)° = 180°

  44x +4 = 180 . . . . . . simplify

  44x = 176 . . . . . . . . . subtract 4

  x = 4 . . . . . . . divide by 44

Answer:

45 × 4 = (9 × 5) × (2 × 2) = (9 × 2) × (5 × 2) = 18 × 10 = ?

Step-by-step explanation:

Which equation shows one way to find the value of 45 × 4?

45 × 4

Splitting each number into factors of each other

45 = 9 × 5

4 = 2 × 2

45 × 4 = (9 × 5) × (2 × 2)

45 × 4 = (9 × 2) × (5 × 2)

45 × 4 = 18 × 10

Option A is the correct option

Answer:

The opposite of -10·t and t - 10·t is t

Step-by-step explanation:

1) The opposite of 4·x and -5 + 4·x is given as follows;

-4·x + (-5 + 4·x) = -4·x -5 + 4·x = -4·x + 4·x - 5 = 0 - 5 = -5

2) The opposite of -10·t and t - 10·t is given as follows;

-(-10·t) + (t - 10·t) = 10·t + t - 10·t = 10·t - 10·t + t = 0 + t = t

3) The opposite of (-7 - 4·v) and -4·v is given as follows;
