y=-3/x-2-1
y=-3x + 2-1
Answer:
4th choice: y=-∛(x+2) - 1
Step-by-step explanation:
It's horizontal translation to left 2 units and vertical translation down 1 unit from y = -∛x
It's reflection of y = ∛(x-2) - 1 over y axis

Answer:
Angle 3 is 113°
Step-by-step explanation:
Angles 2 & 3 is supplementary, so it equals 180°. Subtract 67 from 180 and you get 113. DUH.
Good Luck!!
Answer:
113°
Step-by-step explanation:
6 & 2 make a 180 ° angle
180-67 = 113
113° = angle 6
angle 6 is equivalent to angle 3

Answer:
<B = 95degrees
<D = 137 degrees
Step-by-step explanation:
From the given diagram, the sum of the adjacent sides of the trapezoid is 180degrees. Hence;
<A +<B = 180
85 + <B = 180
<B = 180 - 85
<B = 95degrees
Similarly
<C + <D =180
43 + <D = 180
<D = 180 - 43
<D = 137 degrees
In right △ABC altitude overlineBD is drawn to hypotenuse overline{AC} If AD = 5 and BC = 2√ 21, find DC, BD, and ABAB.
Answer:
[tex]\overline {DC}[/tex] = 7
[tex]\overline {BD}[/tex] = √35
[tex]\overline {AB}[/tex] = 2·√15
Step-by-step explanation:
Please find attached the drawing of right triangle ABC created with MS Visio
Let 'x' represent [tex]\overline {BD}[/tex] let 'y' represent [tex]\overline {DC}[/tex], and let 'z' represent [tex]\overline {AB}[/tex], we get;
5² + x² = z²...(1)
x² + y² = (2·√21)² = 84
x² + y² = 84...(2)
84 + z² = (5 + y)²...(3)
From equation (1), we have;
x² = z² - 5²...(4)
From equation (2), and equation (4), we have;
x² + y² = 84 = (z² - 5²) + y² = 84
∴ z² = 84 - y² + 5² = 109 - y²
z² = 109 - y²...(5)
From equation (3), and equation (5), we have;
84 + z² = (5 + y)² = 84 + (109 - y²) = (5 + y)²
84 + (109 - y²) = (5 + y)²
(5 + y)² - (84 + (109 - y²)) = 0
2·y² + 10·y - 168 = 0
y² + 5·y - 84 = 0
y = (-5 ± √(5² - 4 × 1 × (-84)))/(2 × 1)
y = 7, or y = -12
We note that 'y' is a natural number, therefore, the correct option of the two options is y = 7
y = [tex]\overline {DC}[/tex] = 7
From equation (2), we have;
x² + y² = 84
x² = 84 - y² = 84 - 7² = 35
x = √35
x = [tex]\overline {BD}[/tex] = √35
z² = 109 - y²
∴ z² = 109 - 7² = 60
z = √60 = 2·√15
z = 2·√15
z = [tex]\overline {AB}[/tex] = 2·√15.

Answer:
10. No solutions -- Because 5 can't = 0
11. Infinite Solutions -- Because on both sides of the (=) there is a 10 and a B that (b) and be any # and it will still be =
12. No Solutions -- Because 8 can't = 2
13. One Solution -- Because something (-4) = 9 only one # will fit for x and that # is 13 because 13-4=9
14. Infinite Solutions -- Because both sides of the (=) there is 6z because (3+3) z = (6)z = 6z. and if you but any # for z they will always be =
How do I get the answer to question #5?
Answer:
7 cm
Step-by-step explanation:
Area of a parallelogram formula:
[tex]A=bh[/tex] where b is the base length and h is the height
Plug in known values (A=112, b=16 and h=x)
[tex]112=16x[/tex]
Divide both sides by 16 to isolate x
[tex]\frac{112}{16} = \frac{16x}{16}\\7=x[/tex]
Therefore, x is equal to 7 cm.

the manager of a bookstore uses the equation s = p - 3.5 to find the price a student pays for books
The sale price 's' of a book is $3.50 less than the original price 'p'. This situation is represented by the given equation s = p - 3.5.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is s = p - 3.5, where 's' represents the sale price and 'p' represents the original price of a book.
The equation shows that to get the sale price 's', the original price 'p' is reduced by $3.50.
If the sale price 'p' of a book is $3.50 less than the original price 's', then we can rewrite the equation as p = s + 3.5.
This situation is not represented by the given equation.
If the sale price 's' of a book is $3.50 more than the original price 'p', then the equation would be s = p + 3.5.
This situation is also not represented by the given equation.
Hence, the sale price 's' of a book is $3.50 less than the original price 'p'. This situation is represented by the given equation s = p - 3.5.

Blake collects stamps. He collected a total of 175 stamps. If 72% of the stamps he collected were
foreign, how many other stamps did he collect?
Blake collected stamps that were not foreign.
(Type a whole number.)
Answer: 49
Step-by-step explanation:
If 72% of the stamps he collected were
foreign, the percentage of the other stamps will be: = (100% - 72%) = 28%
Since the total number of stamps collected are 175, the number of other stamps collected will be:
= 28% of 175
= 28% × 175
= 28/100 × 175
= 0.28 × 175
= 49
Therefore, he collected 49 other stamps that were not foreign

Billy and Tommy are playing a dice game with a six-sided die. Billy needs to roll a 5 or higher to win the game. What is the probability that Billy will roll a 5 or higher?
Answer:
Probability that Billy will roll a 5 or higher [tex]=\frac{1}{3}[/tex]
Step-by-step explanation:
Probability refers to chances of occurrence of any event.
If a six-sided die is thrown, possible outcomes are [tex]1,2,3,4,5,6[/tex].
Billy needs to roll a 5 or higher to win the game.
So,
Favorable outcomes are [tex]5,6[/tex]
Number of favorable outcomes [tex]=2[/tex]
Total number of outcomes [tex]=6[/tex]
Probability that Billy will roll a 5 or higher
= Number of favorable outcomes ÷ Total number of outcomes
[tex]=\frac{2}{6}[/tex]
[tex]=\frac{1}{3}[/tex]

90 - 43 = x
Step-by-step explanation:
Answer: 47
Step-by-step explanation:
Dude just subtract 43 from 90, since you are given a 90 degree angle.
But if you need the equation: 43+x-7=90
add 43 and (-7) which gives us 36
new equation is now: 36+x=90
move the 36 to the other side
x=54
now plug it in x(54)-7=47
