Which option shows a graph of 3y+18>5x

Step-by-step explanation:

If the zeros are 5 and 9, then the equation will have the form:

y = a (x–5) (x–9)

We know the point (0, 90) is on the curve, so we can use this to find the coefficient a:

90 = a (0–5) (0–9)

90 = 45a

a = 2

y = 2 (x – 5) (x – 9)

Answer:

y = 2 (x-5) (x-9)

Edge

Answer:

D. R0, 360°

Step-by-step explanation:

Since the transformation is from (x,y) to (x,y), the values stay the same...

It's just like a 360 degrees rotation then, since the end position is identical to the start position.

All other answers would affect at least one of the values to change sign like (-x,y), (x,-y) or (-x,-y)... but a 360 degrees rotation would not.

Answer:

x^3-1

Step-by-step explanation:

f(x)=g(x)-1 since was shifted down 1 unit                                        x^3-1

f(x)=g(x)+1 would have been a shift up of 1 unit                             x^3+1

f(x)=g(x-1) shifted right 1 unit                                                            (x-1)^3

f(x)=g(x+1) shifted left one unit                                                        (x+1)^3

Anyways the answer is f(x)=x^3-1

Answer:

2p, since twice as long would hint to multiplication.

Answer:

The value of x is -3

Step-by-step explanation:

We need to solve the given equation and find value of x

5(x-4)+3x-9x=6-(2x+5)+8x

First solving the brackets

5x-20+3x-9x = 6-2x-5+8x

Now combining the like terms,

5x+3x-9x-20 = -2x+8x+6-5

8x-9x-20 = 6x +1

-x-20=6x+1

Now moving x terms on one side and constants on other

6x+x=-20-1

7x = -21

Dividing both sides by 7

7x/7 = -21/7

x = -3

So, the value of x is -3

Answer: 72

Step-by-step explanation:

Rewriting input as fractions if necessary:

8/9, 7/8

For the denominators (9, 8) the least common multiple (LCM) is 72.

LCM(9, 8)

Therefore, the least common denominator (LCD) is 72.

Rewriting the original inputs as equivalent fractions with the LCD:

64/72, 63/72

[tex]x=\ln 403.429[/tex]

Step-by-step answer:

Given:

In a triangle ABC, AD is the bisector of angle A ....If AB=5.6cm ,AC=4cm and DC=3cm, find BD and DC

This problem can be solved by direct application of the angle bisector theorem, which states that the division of the side opposite to the bisected angles is proportional to the respective sides.

Here we have:

Bisector: AD

Side divided: DC = 3 cm

Length of AB = 5.6

Length of AC = 4.0

Then BD = AB/AC * DC = 5.6/4.0 * 3 = 4.2

BC = BD+DC = 4.2+3 = 7.2

1- Writing the system of equations:

The price of a cup of coffee is denoted by c while the price of a spaghetti is denoted by s

We are given that:

4 cups of coffee and 6 spaghetti cost $20.5

This means that:

4c + 6s = 20.5 ................> equation 1

We are also given that:

1 cup of coffee and 3 spaghetti cost $8.75

This means that:

c + 3s = 8.75 .................> equation 2

2- Solving the equations using substitution methods:

From equation 2:

c = 8.75 - 3s ................> I

Substitute with I in equation 1 and solve for s as follows:

4c + 6s = 20.5

4(8.75 - 3s) + 6s = 20.5

35 - 12s + 6s = 20.5

35 - 6s = 20.5

6s = 14.5

s = $2.41667

Substitute with s in I to get c:

c = 8.75 - 3s

c = 8.75 - 3(2.41667) = 1.4999 = $1.5

3- getting price for 1 cup of coffee and 1 spaghetti:

c + s = 1.5 + 2.41667 = $3.91667

Hope this helps :)

Answer:

The product is -x³ - 2x² + 13x + 26

Step-by-step explanation:

* Lets revise how to find the product of two binomials

- If (ax ± b) and (cx ± d) are two binomials, where a , b , c , d are constant

 their product is:

# Multiply (ax) by (cx) ⇒ 1st term in the 1st binomial and 1st term in the

  2nd binomial

# Multiply (ax) by (d) ⇒ 1st term in 1st binomial and 2nd term in

  2nd binomial

# Multiply (b) by (cx) ⇒ 2nd term in 1st binomial and 1st term in

  2nd binomial

# Multiply (b) by (d) ⇒ 2nd term in 1st binomial and 2nd term in

  2nd binomial

# (ax ± b)(cx ± d) = cx² ± adx ± bcx ± bd

- Add the terms adx and bcx because they are like terms

* Now lets solve the problem

- There are two binomials (13 - x²) and (x + 2)

- We can find their product by the way above

∵ (13)(x) = 13x ⇒ 1st term in the 1st binomial and 1st term in the

  2nd binomial

∵ (13)(2) = 26 ⇒ 1st term in 1st binomial and 2nd term in

  2nd binomial

∵ (-x²)(x) = -x³ ⇒ 2nd term in 1st binomial and 1st term in

  2nd binomial

∵ (-x²)(2) = -2x² ⇒ 2nd term in 1st binomial and 2nd term in

  2nd binomial

∴ The product of (13 - x²)(x + 2) = 13x + 26 - x³ - 2x²

- There is no like terms

- Lets arrange the terms from greatest power to smallest power

∴ The product is -x³ - 2x² + 13x + 26

[tex]p = (0.9801) ^ {30}[/tex]

Step-by-step explanation:

the probability of a jaywalker being hit is

[tex]P = \frac{1}{100} = 0.01[/tex].

So the probability of a jaywalker not being hit is:

[tex]P '= 1-0.01[/tex]

[tex]P '= 0.99[/tex]

As in this experiment the probability of each trial is independent then, the probability that it is not a jaywalker will not be hit if it makes a round trip is:

[tex]P '= (0.99) (0.99) = 0.9801[/tex]

[tex]P '= 0.9801[/tex]

If this experiment is repeated for 30 days then the probability that it is not a jaywalker will not be hit if it makes a round trip is:

[tex]p = (0.9801) ^ {30}[/tex]

Answer:

The answer would be B. 2x+4 / x

For this case we have that by definition of composition of functions that:

[tex](f_ {0} h_ {0} g) = f (h (g (x)))[/tex]

So:

[tex]h (g (x)) = 4 (x-2) -1 = 4x-8-1 = 4x-9[/tex]

So:

[tex]f (h (g (x))) = \frac {4x-9 + 4} {4x-9} = \frac {4x-5} {4x-9}[/tex]

ANswer:

[tex](f_ {0} h_ {0} g) = \frac {4x-5} {4x-9}[/tex]

Option D

Gregory has 2/3 of a pizza and gives 1/4 of an entire pizza to Marlene. By converting the fractions to a common denominator, we find that he gives away 3/8 of his portion of the pizza to Marlene.

Understanding fractions can sometimes be as easy as picturing how you would slice a pie and share it with friends.

Gregory has 2/3 of an entire pizza and decides to give 1/4 of an entire pizza to his friend Marlene.

To solve how much of his portion Gregory gives to Marlene, we need to figure out what fraction 1/4 represents out of the 2/3 that Gregory has.

If we think of the pizza being cut into 12 slices (since 12 is a common multiple of both 3 and 4), Gregory's 2/3 is equivalent to 8/12 of the pizza because (2/3) × (12/1) = 8/12.

Similarly, 1/4 of the pizza is equivalent to 3/12 of the pizza because (1/4) × (12/1) = 3/12.

Now we know that Gregory aims to give away 3/12 of the pizza, but we want to express this as a part of his original 8/12.

To find out what fraction of his part he gives away, we then calculate (3/12) ÷ (8/12).

When we divide these fractions, we can multiply by the reciprocal of the second fraction:

(3/12) × (12/8), which simplifies to 3/8.

Therefore, Gregory gives away 3/8 of his 2/3 of the pizza to Marlene.

Squares 1 and 2 have the same area because they're both (a+b) on a side.

Each of these squares is covered by four identical right triangle tiles, legs a,b, hypotenuse c.  

In the first picture we see the uncovered part of the square, not covered by triangular tiles, is two squares, area [tex]a^2+b^2[/tex].

In the second picture the uncovered part of the square is a smaller square, area [tex]c^2[/tex].

We just moved the tiles around on the square, so the uncovered part is the same in both cases.  So

[tex]a^2 + b^2 = c^2[/tex]
