Can someone actually help me please

Answer: x>5

If I Helped, Please Mark Me As Brainliest, Have A Great Day :D

Answer: x is greater than 5

Step-by-step explanation:

9(2(5)-9)-5 greater than 4

9(10-9)-5 greater than 4

9-5 greater than 4

4 greater than 4

So x MUST be greater than 5

Answer:

the number in front of a term is called a convention examples of single terms three times is a single term the three contents so then it would probably be 24 because 7284 time be planted in their preferred method to show multiplication example 3 evaluate the expression and then you go wide equals 6 and 24 hope this helps it's an example not the real answer though LOL

Answer:

The height of the rocket is greater than or equal to 1.039 feet during first 19.936 seconds.

Step-by-step explanation:

The height of the rocket launched from the ground is modelled after the following expression:

[tex]h(t) = -16.087\cdot t^{2}+320\cdot t +15[/tex] (1)

Where:

[tex]t[/tex] - Time, measured in seconds.

[tex]h[/tex] - Height, measured in feet.

After a careful reading to the statement, we translate all relevant information into the following mathematical inequation:

[tex]-16.087\cdot t^{2}+320\cdot t +15\ge 1.039[/tex] (2)

After some algebra, we get the equivalent inequation:

[tex]-(16.087\cdot t^{2}-320\cdot t -13.961)\ge 0[/tex]

[tex]16.087\cdot t^{2}-320\cdot t -13.961 \le 0[/tex]

[tex](x-19.936)\cdot (x+0.044)\le 0[/tex]

Which means that the following conditions must be observed to satisfy the inequation above:

[tex]x-19.936\le 0\,\land\,x+0.044\ge 0[/tex]

[tex]x\le 19.936\,s\,\land\,x\ge -0.044\,s[/tex]

[tex]0\,s\le x \le 19.936\,s[/tex]

The height of the rocket is greater than or equal to 1.039 feet during first 19.936 seconds.

Answer:

The magnitude of the velocity of the cars after they stick is approximately 3.7 m/s

Step-by-step explanation:

The given parameters are;

The mass of the cart traveling East, m₁ = 10.0 kg

The speed of the cart traveling East v₁=  5.00 m/s

The mass of the cart traveling at an angle of 55° m₂= 7.50 kg

The speed of the cart traveling at an angle of 55°, v₂ = 3.00 m/s

The component of the velocities of the cart raveling at an angle are given as follows;

v = 3.00 × cos(55°)·i + 3.00 × sin(55°)·j

The total momentum before collision = m₁ × v₁ + m₂ × v₂  by substitution is therefore;

m₁ × v₁ + m₂ × v₂ = 10 × 5.00·i + 7.5 × (3.00 × cos(55°)·i + 3.00 × sin(55°)·j)

The total momentum after collision = (m₁ + m₂) × v₃

By the principle of the conservation of linear momentum, whereby the momentum is conserved, we have;

m₁ × v₁ + m₂ × v₂ = (m₁ + m₂) × v₃

10 × 5.00·i + 7.5 × (3.00 × cos(55°)·i + 3.00 × sin(55°)·j) = (10 + 7.5) × v₃

50.00·i + 12.91·i + 18.43·j = 17.5·v₃

62.91·i + 18.43·j = 17.5·v₃

∴ v₃ = (62.91·i + 18.43·j)/17.5 ≈ 3.59·i + 1.05·j

Therefore, the magnitude of the velocity of the cars after they stick = √(3.59² + 1.053²) ≈ 3.7

The magnitude of the velocity of the cars after they stick ≈ 3.7 m/s.

Answer:

[tex]0 \leq x \leq 3[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 25x + 60[/tex]

Required

Determine the domain

The domain, in this case means the possible values of x

From the question, we understand that x represents minutes

Since it's impossible to have a negative minutes, then x starts at 0

i.e. [tex]x \geq 0[/tex] or [tex]0 \leq x[/tex]

Also, from the question, we understand that the time can not be more than 3 minutes

i.e.

[tex]x \leq 3[/tex]

Now, we have two inequalities:

[tex]0 \leq x[/tex] and [tex]x \leq 3[/tex]

Which can be written as:

[tex]0 \leq x \leq 3[/tex]

Hence, the domain is: [tex]0 \leq x \leq 3[/tex]

Answer:

(-3,3)

Step-by-step explanation:

y=3

x=−3

Answer:

x=−1/10 y+ −27/10

x=−1/4 y+ −9/4

Step-by-step explanation:

−10x−y=27

Step 1: Add y to both sides.

−10x−y+y=27+y

−10x=y+27

Step 2: Divide both sides by -10.

−10x /−10= y+27 /−10

x=−1/10 y+ −27 /10

−4x−y=9

Step 1: Add y to both sides.

−4x−y+y=9+y

−4x=y+9

Step 2: Divide both sides by -4.

−4x /−4= y + 9/−4

x= −1/4 y + -9/4

Answer:

-6

Step-by-step explanation:

this is written in point slope form, y=mx+b

we just need to recognize which numbers represent which variables,

(the "b" in the equation is the y-intercept)

Let's line them up to find out our "b"

y=-4x-6

y=mx+b

the -6 is where the "b" is located

Answer:

20 leaves

Step-by-step explanation:

Step one:

given data

we are told that the amount paid =$30

The mean man deducts $3 for every 2 leaves seen on the lawn.

we are expected to estimate the number of leaves that can amount to a $30 deduction.

Step two:

let the number of leaves be x

so if 2 leaves are worth $3 deductible

the x leave will worth $30 deductible

cross multiply we have

x=30*2/3

x=60/3

x=20 leaves

Answer:

Jessica lived 10 months in Spain and 8 months in Colombia.

Step-by-step explanation:

Let x be the months Jessica spent in Spain, and y the months she spent in Colombia:

   1. x + y = 18

Using the information of words per month learned in each country, we can also write the equation:

    2. 160 * x + 200 * y = 3200

So now we have a system of two equations and two unknowns.

First we express y in terms of x, in the first equation:

We replace y in the second equation:

And solve for x:

Finally we use that value of x in the first equation and solve for y:

Jessica lived 10 months in Spain and 8 months in Colombia.
