Answer:
-8x^2·y·z +3y·z^2 -4y
Step-by-step explanation:
It can be helpful to make sure the variables in each term are in alphabetical order. This makes it easier to see "like" terms. The variables in each term are ...
x^2 y z
y z^2
x^2 y z
y
Only the first and third terms are like terms, so those are the only ones that can be combined. Their coefficients are -7 and -1, so sum to -8. The combined term is of highest degree, so in standard form we list that term first.
= -8x^2·y·z +3y·z^2 -4y
What is the vertex of the parabola? y+1=−14(x−2)2 Enter your answer in the boxes.
Answer:
y + 1 = -14(x - 2)^2y = -14(x - 2)^2 - 1

Answer:
y=x^2 - 1, y=5x^3 + 9, and y=2x(x-3)
Step-by-step explanation:
these equations are either parabolas or a cubic function. These graphs do not have a constant rate of change, proving that Jimmy is incorrect. y=20-4x and y=15 are both straight lines/linear.

Find the area of the arrow above.
square inches
Answer:
1100 Inches Squared
Step-by-step explanation:
Let the triangle on the top right be - (i)
Let the triangle on the top left be - (ii)
Let the bottom rectangle be - (iii)
1) The base of the triangle (i) = 10 + (20/2) (It is the base of the rectangle halfed + the given amount of half base of the triangle)
=> 10 + 10
=> 20 in
Base = 20 in
Height = 30 in
Area = 1/2 * 20 * 30
=> 10 * 30
=> 300 in
Triangle (i) = (ii)
So, the area of triangle (ii)
=> 300 in
Area of rectangle,
Length * Breadth
=> 20 * 30
=> 500 in
Total arrow's area = 300 + 300 + 500 (i + ii + iii)
=> 1100
Therefore the total area of the shape = 1100 in squared.
Hope it helps :)
A certain triangle, one angle measures ten degrees more than the second angle and ten degrees less than the third angle. What is the measure of the smallest angle?
Answer:
50°
Step-by-step explanation:
Let :
Let the angle = x
Second angle = x + 10
Third angle = x - 10
Sum of angles in a triangle = 180
x + (x + 10) + (x - 10) = 180
x + x + 10 + x - 10 = 180
3x = 180
x = 180 / 3
x = 60
Smallest angle :
x - 10 = 60 - 10 = 50°
Using the change-of-base formula, which of the following is equivalent to the
logarithmic expression below?
log, 18
Given:
The logarithmic expression is:
[tex]\log_718[/tex]
To find:
The equivalent expression of given expression by using change-of-base formula.
Solution:
The change-of-base formula is:
[tex]\log_ba=\dfrac{\log_ca}{\log_cb}[/tex]
The given expression is:
[tex]\log_718[/tex]
Using the change-of-base formula, we get
[tex]\log_718=\dfrac{\log_c18}{\log_c7}[/tex]
Where, is a constant and c>0.
Let [tex]c=10[/tex], then
[tex]\log_718=\dfrac{\log_{10}18}{\log_{10}7}[/tex]
Therefore, the correct option is a.

The table shows a student's work when solving the equation 8x-(4x-3)=5.
Which statemen ais true?
Answer:
x = 1/2
Step-by-step explanation:
8x-(4x-3)=5
Distribute the minus sign
8x -4x +3 = 5
Combine like terms
4x+3 =5
Subtract 3 from each side
4x+3-3 = 5-3
4x = 2
4x/4 = 2/4
x = 1/2
What is the median of the stem and lear plot
Answer:The median is the middle number of a set of data. The mode is the number that occurs the most in a set of data. You can use a stem-and-leaf plot to find the mean, median and mode of a set of data. ... Sometimes there will only be one number in the middle, and sometimes there will be two numbers

i have a geometry question.
Answer:
Step-by-step explanation:
You already have the area for your triangle. Substract that from the entire area of the rectangle.
To get the area of the rectangle, multiply the length by the height.
15*20 = 300
Now substract your triangle from that :)

Step-by-step explanation:
I use the quadratic formula to solve
Answer:
D. -6 + 2[tex]\sqrt{5}[/tex]
Step-by-step explanation:
The answer is D because to solve for X you use the quadratic formula which is...
-b±[tex]\sqrt{b^{2} - 4ac}[/tex]
now just plug in which would be
-6±[tex]\sqrt{6^{2} - 4(1)(4) }[/tex]
then solve and the final answer would be
-6 ± 2[tex]\sqrt{5}[/tex] but there is only one answer for this which is a positive that is how I got
-6 + 2[tex]\sqrt{5}[/tex]
