C) y= 1/2x +2; -4 ≤ x ≤ 6
D ) y=-2x+2; -∞
Answer:
1. C
2. C
Step-by-step explanation:
1. x = [tex]\sqrt{t}\\[/tex], y = 4t +3
Solve for t:
t = [tex]x^{2}[/tex]
Plug in t:
y = 4([tex]x^{2}[/tex] ) +3
y = 4[tex]x^{2}[/tex] +3
2. x = 2t, y = t + 2
Solve for t:
t = x/2
Plug in t:
y = 1/2x + 2

Step-by-step explanation:
Lamont’s grandmother started a stamp collection in 1914 (year 1) and added the same number of stamps to the collection each year. When Lamont’s mother received the collection in 1954, there were 203 stamps in the collection. Lamont’s mother continued to add the same number of stamps to the collection each year. When Lamont received the collection in 1990, there were 383 stamps in the collection. If Lamont continued to add the same number of stamps each year, how many stamps were in the collection at the end of 2000 (year 86)?
A. 204
B. 293
C. 433
D. 663
Answer: C. 433
Step-by-step explanation:
Linear equation: y=mx+c, where m= constant rate of change, c=initial value of yor y-intercept.
Let x = number of years after 1914.
y= Number of stamps after x years.
In 1954 (year 40), there were 203 stamps in the collection.
i.e. 203=40m+c (i) [rate of change in number of stamps is constant]
In 1990 (year 76), there were 383 stamps in the collection.
i.e. 383=76m+c (ii)
Subtract (i) from (ii)
180= 36m
[tex]\Rightarrow\ m=5[/tex] i.e. 5 stamps added per year.
from (i), [tex]203=40(5)+c\Rightarrow\ c=203-200=3[/tex] [Initially he has 3 stamps]
Stamps in 2000(year 86) = m(86)+c= 5(86)+3
= 430+3
= 433
Hence, correct option is C. 433

Answer:
123, angles are supplementary
Step-by-step explanation:
m<6 = 57
m<1 = 57 ## Corresponding angles
m<1 + m<2 = 180 ## Same side
180 - 57 = 123
What is m∠DEF?
Enter your answer in the box.
There is a triangle DEF in which side DE is congruent to side EF and G is the midpoint of the side DF. Segment EG intersect the side DF at point G. The measure of angle DEG is (3y+4) degrees and the measure of angle FEG is (5y-10) degrees.
Answer:
m<DEF = 8y - 6
Step-by-step explanation:
Given that: DEG = [tex](3y +4)^{o}[/tex], and FEG = [tex](5y-10)^{o}[/tex].
The given triangle is an isosceles triangle with sides DE ≅ DF.
But,
m<DEF = DEG + FEG
= [tex](3y +4)^{o}[/tex] + [tex](5y-10)^{o}[/tex]
= 3y + 4 + 5y - 10
= 8y - 6
m<DEF = 8y - 6
Therefore, the measure of < DEF is 8y - 6.

I have to solve this using perfect squares, is anyone familiar with those?
Given:
The expression is
[tex]\sqrt{180m^2}[/tex]
To find:
The value of the given expression by using the perfect squares.
Solution:
We have,
[tex]\sqrt{180m^2}[/tex]
It can be written as
[tex]=\sqrt{2\times 2\times 3\times 3\times 5\times m^2}[/tex]
[tex]=\sqrt{(2)^2(3)^25m^2}[/tex]
[tex]=\sqrt{(2\times 3\times m)^25}[/tex]
[tex]=\sqrt{(6m)^25}[/tex]
[tex]=6m\sqrt{5}[/tex]
Therefore, the value of given expression is [tex]6m\sqrt{5}[/tex].

Original Price $120 percent of Discount 80% Sale Price = ?
plz hellpppp
Sale Price = $24 (answer). This means the cost of the item to you is $24. You will pay $24 for a item with original price of $120 when discounted 80%. In this example, if you buy an item at $120 with 80% discount, you will pay 120 - 96 = 24 dollars. Hope this is what you're looking for! ^^
____________________________________________________________
セール価格= $ 24（回答）。これはあなたへのアイテムのコストが24ドルであることを意味します。 80％割引すると、元の価格が120ドルの商品に24ドルを支払うことになります。この例では、80％割引で120ドルでアイテムを購入すると、120〜96 = 24ドルを支払うことになります。これがあなたが探しているものであることを願っています！ ^^
Part C Find the length and width of rectangle NEHI, and calculate its area.
Answer:
length of rectangle NEHI = NI = (38 – 8) = 30 feet
width of rectangle NEHI = NE = 5 feet
area of rectangle NEHI = length × width
= 30 × 5
= 150 square feet

How to simplify 1/2
Somebody help meeeee
Step-by-step explanation:
1/2 cannot be simplified, however you can solve this question by shading in the other half of the left square, and taking away a shade on the right one :)
Answer:
ok you can not simplify 1/2 but you can make it a higher proportion basically, one square can be one shaded purple of of the two rectangles and the other could be 4 different squares with two shaded purple
what is the area of the shaded?

What is y? Helppp thank you !
Answer:
y = 42
Step-by-step explanation:
Since QT is a midsegment then it is half of RS , that is
QT = [tex]\frac{1}{2}[/tex] RS, substitute values
y = [tex]\frac{1}{2}[/tex] (y + 42) ← multiply both sides by 2 to clear the fraction
2y = y + 42 ( subtract y from both sides )
y = 42
