What are the solutions to the equation x^2 - 8x= 24
Answer:
Step-by-step explanation:
Try to get all the numbers and variables on one side of the =
X^2 - 8x - 24 = 0
I think solving this equation via factorisation would be difficult so you should use the quadratic formula which I have attached.
14x - 2x + 3
12x + 3
3 (4x + 1)
4x+ 1
1
-8
3(5x + 9)
3(5x + 9)
= 3(5x + 9)
= 5x + 9
= x+9
=x
Answer:
-1/4
Step-by-step explanation:
14x - 2x + 3 = 0
12x + 3 = 0
12x = -3
12x/12 = -3/12
x = -1/4

Identify the value of y.
7(5-5y) = 9y-4-357
Hey there!
Let's solve this equation!
The first step is to use the Distributive Property.
7(5-5y)=9y-4-357
35-35y=9y-361
Combine Like Terms:
-35y-9y=-361-35
-44y=-396
Divide both sides by -44:
y=9

A toy car launches off a ramp with a height of 6 feet with an upward velocity of 10 feet per second. The function h = -16t^2 +10t +6 gives the height in feet of the car after t seconds. After how many seconds does the car land on the ground?
On factoring, the value of t is 1. This shows that the car will land on the ground after 1 sec.
Solving quadratic functionsQuadratic functions are functions having a leading degree of 2.
Given the function height in feet of the car after t seconds expressed as
h = -16t^2 +10t +6
The height of the car on the ground is zero, hence:
16t^2 -10t -6 = 0
8t^2 - 5t - 3 = 0
Factorize the quadratic function
8t^2 - 5t - 3 = 0
On factoring, the value of t is 1. This shows that the car will land on the ground after 1 sec.

The probability of an event happening is given as 0.45
What is the probability of the event NOT happening?
Given:
⇒ Probability of happening of an event = 45%
To Find:
⇒ Probability of event
Now, probability of happening of an event is 45% means non happening event is 100 - 45 = 55%.
⇒ Probability of happening event = 45/100
⇒ Probability of happening event = 0.45
⇒ Probability of non happening event = 55/100
⇒ Probability of non happening event = 0.55
Hence, the correct option is (c) 0.45.
Extra Info:
Probability is the likelihood /chances of a given event's occurence which is expressed as a number between 1 and 0.

Tracy wants to make a cylindrical model. The height of the cylindrical model, H(V), in inches, is modeled by this
equation, where Vis the volume of the cylindrical model, in cubic inches.
H(V) = 2. 6937
What is the average rate of change of the model's height when its volume changes from 512 cubic inches to
1,000 cubic inches?
The model's height increases by approximately 21. 52 inches for every 1-cubic-inch increase in its volume.
The model's height increases by approximately 0. 022 inch for every 1-cubic-inch increase in its volume.
The model's height increases by approximately 0. 011 inch for every 1-cubic-inch increase in its volume.
The model's height increases by approximately 26. 9 inches for every 1-cubic-inch increase in its volume.
The average rate of change of the height function is slope of the height function
The model's height increases by approximately 0.011 inch for every 1-cubic-inch increase in its volume.
How to determine the average rate of change?The height function is given as:
[tex]H(V) = 2.69\sqrt[3]{V}[/tex]
When V = 512, the function becomes
[tex]H(512) = 2.69\sqrt[3]{512}[/tex]
[tex]H(512) = 21.52[/tex]
Similarly;
When V = 1000, the function becomes
[tex]H(1000) = 2.69\sqrt[3]{1000}[/tex]
[tex]H(1000) = 26.9[/tex]
The average rate of change is then calculated as:
[tex]H' = \frac{H(1000) - H(512)}{1000 - 512}[/tex]
This gives
[tex]H' = \frac{26.9 - 21.52}{1000 - 512}[/tex]
[tex]H' = \frac{5.38}{488}[/tex]
Evaluate the quotient
[tex]H' = 0.01102459016[/tex]
Approximate
[tex]H' = 0.011[/tex]
Hence, the model's height increases by approximately 0.011 inch for every 1-cubic-inch increase in its volume.

A stack of books is 56 inches high. How high is it in feet and inches?
1 foot = 12 inches
56 inches / 12 inches = 4.66 feet = 4 feet and 8 inches
Answer:
4 feet and 8 inches
Step-by-step explanation:
To convert a high number of inches to feet you divide it by 12 since 12 inches makes 1 foot.
So 56÷12 = 4 reminder 8
The remainder we keep it as inches
So our answer is 4 feet and 8 inches.

Answer:
b. translation, rotation
Step-by-step explanation:
When a shape is translated, that just means nothing about it has changed except it's location on the coordinate plane. This is that happened with shape 1 - it was translated, and that created shape 2.
When a shape is rotated, that just means it is turned (or rotated) at a specific point. This is what happened to shape 2 that changed it to shape 3.
The other two transformations that aren't shown in this specific example are dilation, which means that the shape either shrinks or grows, and reflection, which means that the shape is reflected across the y-axis or the x-axis.
I included a picture with all four transformation examples in it. I hope this helps! Have a lovely day!! :)

Answer:
a cone with a radius of 4 units
Step-by-step explanation:
when rotating something, this involves a circle. so, the result will always be round and never edgy. therefrom the first option is wrong.
and we are rotating a triangle. the result will have a wide base and a pointed tip. so, the third option is wrong.
the rotation does not make the basic shape smaller. so, the second option is wrong.

Answer:
A. 0.125 foot per square feet
Step-by-step explanation:
When finding average rate of change, use the formula
ΔY/ΔX
The ΔY, or Y final - Y initial would be 1.5-1.0, which is equal to 0.5.
The ΔX, or X final - X initial would be 7-3, which is equal to 4.
Plug these values into the equation ΔY/ΔX to get 0.5/4.
This will give you 0.125.
What is the value of X
Answer:
x ≈ 23.31
Step-by-step explanation:
We can use the law of cosines because we know 2 sides and 1 angle.
The general formula for the law of cosines if the triangle sides are a, b,c and α is the angle between sides a and b. c is the missing side.
[tex]c = \sqrt{a^{2} +b^{2} -2*a*b* cos \alpha }[/tex]
In our problem the law of cosines is
x = [tex]\sqrt{21^{2} +13^{2} - 2*21*13 *cos 83}[/tex]

At a concession stand 6 hot dogs cost $6.72. At this rate, how much would 8 hot dogs cost, in dollars and cents?
Answer:
$8.96
Step-by-step explanation:
Since 6 hot dogs are $6.72, 1 hot dog would be that divided by 6, which is $1.12. Now we want the cost of 8 of those hot dogs, so we have to multiply by 8. Hence the answer is $1.12 * 8 = $8.96.

Write the equation of the line that passes through the point (2, -1) and has a slope of -3.
Answer:
Y=-3x+5Step-by-step explanation:
slope is -3/1
Slope is Rise/Run
meaning 3 down and 1 right
so in this case the down means the Y-axis
and the right means the x-axis
so lets put out some points.
(2,-1)
Then 1 right and down 3
(3, -4)
(4,-7)
and soo on, but we want to fin the point where x is zero.
Why?
Because that is where the y-Intercept is at.
Slope Intercept form is y=mx+b
Where m is the slope
And b is the y- Intercept
Soooo
Let's work backwards
Instead of Right 1 and Down 3 lets do
Left 1 and Up 3
And we will be starting with our original point
(2,-1)
then left 1, Up 3
2-1=1
-1+3=2
soo...
(1,2)
then again
(0,5)
That is our Y-intercept.
Now lets put all of it together.
Y=Mx+B
M=Slope
B=Y-Intercept
Y=-3x+5
