Answer:
I might be able to answer this if I could see the numbers for both the parallelograms. I can see it but some of the numbers are cut off.
Step-by-step explanation:
Thank you.
Answer:
Step-by-step explanation:
a.
Base=2+5=7
height=4+2=6
area=7×6=42 sq. units
eq. of base is y=-2
eq. of upper side is y=4
slope of left side is
y-(-2)=(0-(-2))/(-3-(-2))(x-(-2))
y+2=2/(-1) (x+2)
y+2=-2(x+2)
y+2=-2x-4
y=-2x-6
any line parallel to it is
y=-2x+a
(4,0) lies on it.
0=-2×4+a
a=8
eq. of right hand side is
y=-2x+8
b.
base=-3-(-7)=4
height=5-(-2)=7
area=4×7=28 sq. units.
eq. of base is
y=-2
eq. of upper side is
y=5
eq. of left side is
[tex]y-y1=\frac{y2-y1}{x2-x1}(x-x1)\\y-(-2)=\frac {5-(-2)}{0-(-7)}(x-(-7)}\\y+2=1(x+7)\\y=x+7-2\\y=x+5\\any~line~parallel~to~above~line~is \\y=x+k\\point~(0,1) ~lies~on~it.\\so~1=0+k\\k=1\\eq. of ~lie~on~the~right~side~is\\y=x+1[/tex]

The profits of Mr. Unlucky's company can be represented by the equation f(x)=−3x^2+18x−4, where y is the amount of profit in hundreds of thousands of dollars and x is the number of years of operation. He realizes his company is on the downturn and wishes to sell before he ends up in debt.What is the maximum profit?
Answers
Answer:
Step-by-step explanation:
maximum years would be where x=-b/2a or -18/-6 or x=3
put that into the equation to get y=-27+54-4=23 hundreds of thousands.
from year 3 on, the profit decreases
the zero point is where y=0 this is -3x^2+18x-4=0
or 3x^2-18x+4=0
quadratic formula
x=(1/6)(18+/-sqrt(324-48)); sqrt 276=16.61
x=(34.61/6)=5.77 years, so 2.77 years of decreasing profits.

The number line shows three groups of a number, which results in a product.
Answers
Answer:
I cannot see the number line mentioned here, but I'll explain how you multiply negative and positive using tiles and number line.
To multiply positive and a negative nunber, for instance, 2(–3), you'll think of it as 2 groups of negative one in three's. Using tiles you have
–1 –1
–1 –1
–1 –1
Two groups of negative one in three's, adding that up we have 6.
Using number line. See 2(–3), for instance, as moving twice in intervals of –3. If I am to multiply that, starting from 0, if I move once, I'll land at –3, if I move one more time, I'll land at –6. Since I am to move twice, that's the required answer.

Rise over run is often referred to as the slope of the line or the gradient of the line. It is the measure obtained by dividing the y component of the line with the x component of the line. The rise over run ratio is an important characteristic to define the line, and is required to find the equation of the line.

f(x) = RootIndex 3 StartRoot x + 6 EndRoot minus 1
f(x) = RootIndex 3 StartRoot x minus 6 EndRoot minus 1
Answers
The translation of the parent function is:
g(x) = ∛(x + 6) + 1
How do translations work?There are two types of translations, these are:
Horizontal translation:
For a function f(x), a horizontal translation of N units is written as:
g(x) = f(x + N)
If N is positive, the translation is to the left.If N is negative, the translation is to the right.Vertical translation:
For a function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N
If N is positive the translation is upwards.If N is negative the translation is downwards.Here we start with the parent function:
f(x) = ∛x
And we apply two translations such that:
g(x) = ∛(x + a) + b
Such that:
g(-7) = 0
g(2) = 3
Then we have the system of equations:
∛(-7 + a) + b = 0
∛(2 + a) + b = 3
From the options, the only ones that make the first option true are:
g(x) = ∛(x + 6) + 1
Such that when evaluated in x = -7 we get:
g(-7) = ∛(-7 + 6) + 1 = ∛(-1) + 1 = 0
When evaluated in x = 2 it gives:
∛(2 + 6) + 1 = ∛(8) + 1 = 2+ 1 = 3
So the only option that meets these conditions is:
g(x) = ∛(x + 6) + 1
Which is a translation to the left of 6 units and up 1 unit.
