Step 2: Simplify
Combine like terms (x³): -20x + 8x - 3x + 15xCombine like terms (x): 0Answer:

Step-by-step explanation:
We are given the expression:
[tex]50x^3-20x+8x-21x^3-3x+15x-29x^3[/tex]
We want to simplify it, so we must combine the like terms. For this equation, the like terms are terms with x³ or x.
First, combine all the x³ terms.
[tex](50x^3-21x^3-29x^3)-20x+8x-3x+15x[/tex]
[tex](0x^3)-20x+8x-3x+15x[/tex]
[tex]-20x+8x-3x+15x[/tex]
Next, combine all the remaining terms, because they are all terms with an x.

What is the sign of 3 x y 3xy3, x, y when x > 0 x>0x, is greater than, 0 and y < 0 y<0
Answer:
The sign is negative
Step-by-step explanation:
Given
[tex]Expression = 3xy[/tex]
[tex]x > 0[/tex]
[tex]y<0[/tex]
Required
Determine the sign
The expression can be split into 3 factors
[tex](3) (x) (y)[/tex]
If x > 0 then x is positive and If y < 0 then y is negative
So, the expression becomes:
[tex](+3) (+x) (-y)[/tex]
Leave only signs
[tex](+) (+) (-)[/tex]
[tex]+ * + = -[/tex]
So, we have:
[tex](+*+) (-)[/tex]
[tex](+) (-)[/tex]
[tex]+ * - = -[/tex]
So, we have:
[tex](+) (-) = -[/tex]
Hence, the sign of the expression is negative
Take for instance;
[tex]x = 2[/tex]
[tex]y = -4[/tex]
The expression would be:
[tex]3 *2 * - 4 =-24[/tex] -- negative
A candle burned at a steady rate. After 33 minutes, the candle was 11.2 inches tall. Eighteen minutes later, it was 10.75 inches tall. Use an equation in point-slope form to determine the height of the candle after 2 hours. Round the answer to the tenth place if necessary
Answer:
9.025 inches
Step-by-step explanation:
Let the length be represented by:
[tex]L = mt+L_0[/tex]
Where [tex]L[/tex] is the length of candle at time [tex]t[/tex]
[tex]m[/tex] is the rate at which the candle is burning.
And [tex]L_0[/tex] is the initial length of the candle.
As per the question statement, let us put the given values in the equation.
[tex]11.2 = m\times 33 + L_0 .... (1)\\10.75 = m\times 51+L_0 ..... (2)[/tex]
Subtracting (1) from (2):
[tex]0.45 = -18m\\\Rightarrow m = -0.025[/tex]
Putting the value of [tex]m[/tex] in the equation (1):
[tex]11.2 = -0.025 \times 33+L_0\\\Rightarrow L_0 = 12.025[/tex]
Therefore, the equation becomes:
[tex]L = -0.025t + 12.025[/tex]
Now, we have to find the height of candle after 2 hours.
2 hours mean 120 minutes.
[tex]L = -0.025 \times 120 + 12.025\\\Rightarrow L = 9.025\ inches[/tex]
Therefore, the height of candle is 9.025 inches.

Answer:
When x=1/2, y=28/3
when x =0, y=9
Equation is y=2/3 x + 9
Step-by-step explanation:
First lets convert them to fractions to make it easier. Also put them in order.
X Y
0
1/2
3/4 19/2
1 29/3
6/5 49/5
You can find the slope since we know 2 points.
(3/4, 19/2) and (6/5, 49/5)
m=3/10 / 9/20
m=2/3
y=2/3 x + b
Lets plug in x and y points to find the y-int
19/2=2/3(3/4) + b
b=9
Therefore y=2/3 x + 9
When x=1/2, y=28/3
when x =0, y=9

(a+2b)² ?????????????????????
Answer:
a² + 4ab + 4b²
Step-by-step explanation:
Given
(a + 2b)²
= (a + 2b)(a + 2b)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis
= a² + 2ab + 2ab + 4b² ← collect like terms
= a² + 4ab + 4b²

Kathy is a repair technician for a phone company. Each week, she receives a batch of phones that need repairs. The number of phones that she has left to fix at the end of each day can be estimated with the equation P=108−23d P = 108 − 23 d , where P is the number of phones left and d is the number of days she has worked that week. What is the meaning of the value 108 in this equation?
Answer:
What 108 represents here is that the total number of phones she has to fix each week is 108 phones
Step-by-step explanation:
The linear equation is
P = 108-23d
compare this with the general form;
y = mx + c
we have;
P = -23d + 108
We can see that 108 represents the y-intercept in this case
The x-value at the y-intercept is 0
So what this mean is that the number of phones she has to fix each week is 108
100 POINTS HELP PLEASE ONE HUNDRED POINTSSS identify each measurement as a diameter, radius, or circumference of the circular object that estimate the other two measurements of the circle
1. The length of the minute hand on a clock is 5 inches
2. The distance across hey sink drain is 3.8 cm
3 The tires on a mining truck are 14 feet tall
4. The fence around a circular pool is 75 feet long.
Answer:
1. 15.708
2. The radius would be half of the distance across the drain, or half of the diameter. Half of 3.8cm, or 3.8cm / 2 is 1.9cm.
The circumference is the distance around the drain, or if you trace the entire circle. The formula to find the circumference of a circle is 2 multiplied by pi and the radius of the circle, or C = 2(pi)r. Here, we just found the radius, so the circumference is 2 * pi (which is approximately 3.14) * 1.9cm, or approximately 11.9cm!

Melissa works for a florist. She used her employee discount to purchase 10 roses at $1.00 each. If melissa saved $4.00 by using her employee discount, what is the regular price if one rose purchased from the florist?
Answer: $1.4
Step-by-step explanation:
Given that:
Discounted price roses = $1
Amount saved = $4
Regular price - discounted price = amount saved
x - 10(1) = 4
x - 10 = 4
x = 4 + 10
x = $14
Regular price of 10 roses = $14
Regular price per rose = $14 / 10 = $1.4

The coterminal angle of angle [tex]\frac{7\pi}{8}[/tex] is [tex]\frac{23\pi}{8}[/tex].
The coterminal angles are the angles that have the same initial side and the same terminal sides.
To determine the coterminal angle of a given angle just adding or subtracting 360° or 2π to it.
The coterminal angle of angle [tex]\frac{7\pi}{8}[/tex] is,
[tex]2\pi+\frac{7\pi}{8}=\frac{16\pi+7\pi}{8} =\frac{23\pi}{8}[/tex]
Hence, The coterminal angle of angle [tex]\frac{7\pi}{8}[/tex] is [tex]\frac{23\pi}{8}[/tex].

Answer:
arc AB = 102°arc ADB = 258°Step-by-step explanation:
The measure of an arc is the measure of the corresponding central angle.
__
Short arc AB is shown as subtending a central angle of 102°, so the measure of arc AB is 102°.
__
The sum of arc measures in a circle is 360°, so the measure of arc ADB is 258°, the value that adds with 102° to make 360°.
