y=x²-3

y= 2/x + 7

3x + 2y = 6

**Answer:**

3x + 2y = 6

**Step-by-step explanation:**

When you solve for y in this equation, it is in the same format as the slope-intercept equation.

3x + 2y = 6

2y = -3x + 6

y = -3/2 x + 3

The slope intercept equation is ...

y = mx + b

(m can be any number)

The slope-intercept equation *is for linear functions*!

Dalton built a linear model to show the height of a meteor falling to the Earth. The meteor starts at 100 km above the Earth's surface and falls at a rate of 20km per second. The x values represent the time in seconds and the y values represent the height of the meteor. What does the domain represent in context of the model?

**Answer:**

The domain represents the time of motion of the meteor as it falls from 100 km height above the Earth's surface at a speed of 20 km

**Step-by-step explanation:**

The given parameters from the question are;

The elevation of the meteor above the Earth's surface = 100 km

The rate at which the meteor falls = 20 km per second

The 'x' values represent the time in seconds and the 'y' values represent the meteor's height

Therefore, we have;

y = 100 - 20·x

The domain of a function is the set of inputs to the function

Therefore, the domain represent the time it takes the meteor to reach the given 100 km height above the Earth's surface

At the start x = 0 seconds

On the Earth's surface, y = 0, therefore;

0 = 100 - 20·x

x = 100/20 = 5

When the meteor just touches the Earth's surface x = 5 seconds

Therefore, the domain is 0 ≤ x ≤ 5.

An extended family is trying to plan a reunion and needs to find out where everyone would like to attend. Jill decides to send an e-mail to one person from each of the different families to get their opinion. She then follows up with those that she doesn't hear from. Is this a good way to collect data?

**Answer:**

I don't think so. Because what if that specific family member never checks their email. I think a good way would have been to email more than one or every person in that family (now since its extended you might not know everyone so just as many as you know of)

Translate the following sentence into an equation using n for the unknown number. Then solve for n.

when 15 is decreased by three times a number, the result is 21

a.

15 - 372 = 21

n = -2

b.

312 - 15 = 21

n = -2

C.

31 - 15 = 21

n = 12

d.

15 - 3n2 = 21

n-2

**Given:**

15 is decreased by three times a number, the result is 21.

**To find:**

The equation for the given statement and solve it.

**Solution:**

Let n be the unknown number. Then,

Three times of a number = [tex]3n[/tex]

15 is decreased by three times a number = [tex]15-3n[/tex]

It is given given that the result after subtraction is 21. So,

[tex]15-3n=21[/tex]

[tex]-3n=21-15[/tex]

[tex]-3n=6[/tex]

Divide both sides by -3.

[tex]n=\dfrac{6}{-3}[/tex]

[tex]n=-2[/tex]

**Therefore, the required equation is [tex]15-3n=21[/tex] and its solution is [tex]n=-2[/tex]. Hence, the correct option is (a).**

**Answer:**

a

b+g=708

15b+10g=8640

**Answer:**

b=312

g=396

you can use substitution or elimination

**Step-by-step explanation:**

(b+g=708)10

(15b+10g=8640)1

(10b+10g=7080)-

(15b+10g=8640)

10b-15b=-1560

-5b=-1560

divide both sides by -5

b=312

then substitute

b+g=708

312+g=708

g=708-312

g=396

so b=312

g=396

Find the measure of the angle indicated (x). Round to the nearest tenth. Show your work to support your answer.

**Answer:**

x = 17.1°

**Step-by-step explanation:**

tan x = 4/13 = 0.3077

x = 17.1°

The measure of the **angle **θ from the given **triangle **is 17.9°.

The sides and **angles **of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six **trigonometric **ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

From the given triangle, AC=13 and BC=4 units.

We know that, sinθ=Opposite/Hypotenuse

sinθ= 4/13

sinθ= 0.3076

θ=17.9°

Therefore, the measure of the **angle **θ from the given **triangle **is 17.9°.

A model rocket is launched straight upward. The solid fuel propellant pushes the rocket off the ground at an initial velocity of 50 feet per second.

s(t)= -4t2 + 50t - 84. Show work to get credit

a. What is the maximum height reached by the rocket?

b. What time will it reach the maximum height?

c. You forgot to put the parachute in the rocket. When will the rocket hit the ground?

**Answer:**

**a) 72.25sec**

**b) 6.25secs**

c) **after 10.5secs and 2 secs **

**Step-by-step explanation:**

Given the height reached by the rocket expressed as;

s(t)= -4t^2 + 50t - 84

At maximum height, the velocity of the rocket is zero i.e ds/dt = 0

ds/dt = -8t + 50

0 = -8t + 50

8t = 50

t = 50/8

t = 6.25secs

**Hence it will reach the maximum height after 6.25secs**

To get the maximum height, you will substitute t - 6.25s into the given expression

s(t)= -4t^2 + 50t - 84

s(6.25) = -4(6.25)^2 + 50(6.25) - 84

s(6.25) = -156.25 + 312.5 - 84

s(6.25) = 72.25feet

**Hence the maximum height reached by the rocket is 72.25feet**

The rocket will reach the ground when s(t) = 0

Substitute into the expression

s(t)= -4t^2 + 50t - 84

0 = -4t^2 + 50t - 84

4t^2 - 50t + 84 = 0

2t^2 - 25t + 42 = 0

2t^2 - 4t - 21t + 42 = 0

2t(t-2)-21(t-2) = 0

(2t - 21) (t - 2) = 0

2t - 21 = 0 and t - 2 = 0

2t = 21 and t = 2

t = 10.5 and 2

**Hence the time the rocket will reach the ground are after 10.5secs and 2 secs **

You have 2 totals so the number of males + females = 127 so x + y = 127

Then there are 23 more males than females, it did not say 23 times more so B is out, so the female number + 23 = male number so y + 23 = x

Therefore letter C is the answer.

James is solving a number puzzle that involves three integers, a, b, and c, where c is a positive integer. The product of a and b is 6. The product of a and c is -4. The product of b and c is -6.

**Given:**

Three integers, a, b, and c, where c is a positive integer.

The product of a and b is 6.

The product of a and c is -4.

The product of b and c is -6.

**To find:**

The values of a,b and c.

**Solution:**

According to the given information:

[tex]ab=6[/tex] ...(i)

[tex]ac=-4[/tex] ...(ii)

[tex]bc=-6[/tex] ...(iii)

From (ii), we get

[tex]a=-\dfrsc{4}{c}[/tex] ...(iv)

From (iii), we get

[tex]b=-\dfrsc{6}{c}[/tex] ...(v)

Putting [tex]a=-\dfrsc{4}{c}[/tex] and [tex]b=-\dfrsc{6}{c}[/tex] in (i), we get

[tex]\dfrac{-4}{c}\times \dfrac{-6}{c}=6[/tex]

[tex]\dfrac{24}{c^2}=6[/tex]

[tex]\dfrac{24}{6}=c^2[/tex]

[tex]4=c^2[/tex]

Taking square root on both sides, we get

[tex]\pm \sqrt{4}=c[/tex]

[tex]\pm 2=c[/tex]

It is given that c is a positive integer. So, it cannot be negative and the only value of c is [tex]c=2[/tex].

Putting [tex]c=2[/tex] in (iv), we get

[tex]a=-\dfrsc{4}{2}[/tex]

[tex]a=-2[/tex]

Putting [tex]c=2[/tex] in (v), we get

[tex]b=-\dfrsc{6}{2}[/tex]

[tex]b=-3[/tex]

**Therefore, the values of a,b,c are **[tex]a=-2,b=-3,c=2[/tex]**.**
