Hey! This is a maximum because that's where it peaks. It doesn't go any higher from there so the coordinates are (0,-1) or A.
A trapezoid is a quadrilateral with two parallel sides of different lengths. This means that any of the two sides can be called a base, and that the trapezoid is unique because it has two bases.
the formula for finding the area of a trapezoid is
[(b1 + b2) x h] / 2
Substituting the values:
((19 + 29.2) * (12.6)) / 2
303.66 in ^ 2
Answer:
the area of the trapezoid is:
303.66 in ^ 2
Answer:
I don't see any answer choices, but read my explanation
Step-by-step explanation:
Any line with a slope of 3 would be parallel to y=3x+2.
For example,
y=3x+4
y=3x-1
y=3x
All of these lines are parallel to the original equation
The sentence that explains how the bonding pattern in metals makes them good conductors of electricity is <u>A. They are willing </u>to give up their valence electrons.
<h3>What are valence electrons?</h3>
Valence electrons are the electrons in the outermost shell, or energy level, of an atom, which participate in the formation of a chemical bond when the outer shell is open.
<h3>Answer Options:</h3>
A. They are willing to give up their valence electrons.
B. Their nucleus has more protons than neutrons.
C. They are malleable.
D. They have a simpler electron arrangement.
Thus, the sentence that explains how the bonding pattern in metals makes them good conductors of electricity is <u>Option</u> A.

Well, there are three different ways to solve systems of equations:
a) Graphing
b) Substitution
c) Elimination
Graphing:
If your system of equations are written in slope-intercept form (y=mx+b "m" being the slope and "b" being the y-intercept) its quite easy.
The y-intercept is pretty much where your line touches the y-axis so if your first equation is: y=3x-2 then you will put your first point on (0,-2). Then from that point you follow the slope. if the slope is 3 then you'll rise 3 and run 1 (go three times up and one to the right and put your point right there) till you feel you have enough points to make a line. You do the same process with your second equation.
Substitution:
This is best when you have a system of equations in which an equation tells you what x or y are equal to. For example: if I have "4x+2=y" and "2y+3x= 26" you can "replace" your "2y" with the equation "4x+2=y" which gives you a brand new equation: " 2(4x+2)+3x=26". To solve this you do the distributive property and link like terms which gives you the equation "11x+4=26". Then you solve like a normal equation, isolating x and then you'll get the value of x (in this case x=2). Now you go to the first equation "4x+2=y" and replace "x" to its value (in this case it's 2) and you get y (in this example, y=10).
Elimination:
I think this one is one of the easiest methods. Let's say my systems of equations is "5x-6y=-32" & "3x+6y=48". If you take a look at y's coefficients, you see they are the same. So you can "cancel them out" like this:
5x-6y=-32
+ 3x+6y=48
-----------------------
8x=16 <-------- when you get this, you can solve like a normal equation
x=2
Also, if you have, for example:
2x+6y=190 & 2x+3y=130
You can solve this by: canceling x or multiplying the second equation by 2 and canceling y.
I'm gonna show you how to do the second way (multiplying and canceling y)
My second equation is "2x+3y=130". To get an equivalent equation, I just have to multiply the whole equation by any number. If I want to cancel y, then I have to multiply by 2.
So "2x+3y=130" turns into "4x+6y=260"
Now you follow the same procedure as before:
2x+6y=190
- 4x+6y=260
-------------------------------
-2x= -70
2x=70--------> x=35
Then you pretty much follow the substitution method by replacing "x" to "35" in one of the equations.
