Answer:
[tex]x^{2}-2x-24[/tex]
Step-by-step explanation:
First, expand the parentheses using multiplication:
[tex](x^{2} -2x+9x-18) -9x-6[/tex]
Now we simply combine life terms, giving us:
[tex]x^{2}-2x-24[/tex]
Hope this helps!
Hi there! Let's solve this step-by-step!
We need to expand (x + 9)(x - 2) by multiplying the two terms. We can use this rule: (A+B)(C+D)+AC+AD+BC+BD=
In the problem, (X+ 9)(x-2) -9x- 6
The resulting expression will consist of 4 terms:
First term: x and x
Second term: x and -2
Third term: 9 and x
Fourth term: 9 and -2
Now, we expanded (X+ 9)(x-2) to (xx ⋅ 2 + 9x - 9 ⋅ 2)
Our new problem is: (xx ⋅ 2 + 9x - 9 ⋅ 2) - 9x - 6
Now, we need to combine like factors in this term (xx) by adding up all the exponents and copying the base. No exponent implies the value of 1.
The like factors are: x and x
[tex](x^1^+^1-2x+9x-18)-9x-6[/tex]
Now, your answer is: [tex]x^2-2x-24[/tex]

What is the y-intercept in this equation?
6x + 3y = 24
Answer: y=−2x+8
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
Let's rewrite this in slope intercept form, and isolate y on the left side. First, subtract 6x from both sides:
3y = 24 - 6x
Then divide both sides by 3:
y = -2x + 8
Now that it's in y = mx+b form, we can see that the slope is -2, and the y intercept is 8.
Hope this helps!

What is the pattern as the exponents decrease?
O subtract 5 from the previous value
O subtract 100 from the previous value
O divide the previous value by 5
O divide the previous value by 25
Answer:
C
Step-by-step explanation:
Edge 2020
The pattern as the exponent decreases is (c) divide the previous value by 5
How to determine the pattern?The sequence on the table are given as:
125, 25, 5, 1, 1/5, 1/25......
From the above sequence, we have:
125/5 = 25
This means that the current value is gotten by dividing the previous by 5
Hence, the pattern as the exponent decreases is (c) divide the previous value by 5

Which proportion must be true?
*answers are in the picture*
Answer:
St/EF = WR/CD
Step-by-step explanation:
The ratio of corresponding sides is same for all the sides for similar polygon. the correct proportion is,
[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]
Thus the option H is the correct option.
To find the correct proportion we need to know about the properties of slimier polygon.
What are the properties of similar polygon?Two polygons are said to be similar or congruent pentagon-
The corresponding angle of two pentagons are congruent.
The ratio of corresponding sides is same for all the sides.
The figure given in the problem of similar two polygons with six sides.
Rearrange the second figure as shown in figure.
As for the similar polygons, the ratio of corresponding sides is same for all the sides.
Thus the sides shown in the two rearranged figure must be same. Therefore,
[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]
Hence the correct proportion is,
[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]
Thus the option H is the correct option.

A submarine descends to -100 feet in 2 minutes and -250 feet in five minutes. Write and solve an equation to find the depth of the submarine in 8 minutes.
Answer:
-400
Step-by-step explanation:
So, to find what the depth would be in 8 minutes, you have to find the depth for ONE minute. So, you divide -100 by 2 and you get -50 in a minute. Next thing you do is you multiply -50 by 8. You get -400. And there's your answer!

Fred has 5 3/4 feet of yarn he will use 1/8 foot of yarn for each decoration he makes what's the greatest number of decorations can Fred make
Answer: Tthe greatest number of decorations can Fred make = 46
Step-by-step explanation:
Total yarn = [tex]5\dfrac34[/tex] feet [tex]=\dfrac{23}{4}[/tex] feet
Yarn required for each decorartion = [tex]\dfrac18[/tex] foot
The greatest number of decorations can Fred make = (Total yarn) ÷ (Yarn required for each decorartion)
[tex]=\dfrac{\dfrac{23}{4}}{\dfrac{1}{8}}\\\\\\=\dfrac{23}{4}\times8\\\\=23\times2\\\\=46[/tex]
Hence, the greatest number of decorations can Fred make = 46

Find the length of each segment write your answer in simplest radical form. I NEED HELP ASAP
Answer:
1. 5
2. [tex]\sqrt{85}[/tex]
3. [tex]\sqrt{26}[/tex]
Step-by-step explanation:
1. just count the units: 5 units
2. Find the slope = rise/run = -7/6
you now have a right triangle, one side is 7 units (from the rise), and the other is 6 units (from the run)
use the pythagorean theorem to find the hypotenuse.
[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]7^{2} + 6^{2} = c^{2}[/tex]
49 + 36 = [tex]c^{2}[/tex]
85 = [tex]c^{2}[/tex]
[tex]\sqrt{85} = \sqrt{ c^{2}[/tex]
[tex]\sqrt{85} = c[/tex]
Simplify the radical, but [tex]\sqrt{85}[/tex] is farthest that it can go, so that is the answer.
3. same process as 2
slope = -1/5
[tex]1^{2} + 5^{2} = c^{2}[/tex]
1 + 25 = [tex]c^{2}[/tex]
26 = [tex]c^{2}[/tex]
[tex]\sqrt{26} = c[/tex]
That is the farthest it can go, so that will be the answer.
