A side of the triangle below has been extended to form an exterior angle of 135º. Find
the value of x.
xo
135
115
Answer:
X = 45
Step-by-step explanation:
x + 135 = 180 {Linear pair}
x = 180 - 135 {Subtract 135 from both sides}
x = 45
Simplify: A. 35/6 B. 29/6 C. 12/5 D. 1/6
Answer:
[tex] \frac{49 - 3}{6} + \frac{24 - 17}{3} = \frac{46}{6} + \frac{7}{3} = \frac{46 + 7 \times 2}{6} = \frac{60}{6} = 10[/tex]
Which of these sets of angle measures could be the three angles in a triangle? a 40, 50, 60 b 50, 60, 70 c 60, 70, 80 d 70,80, 90
Answer:
It’s going to be B. 50+60+70=180 which is how many degrees are in a triangle.
How can I find 75% of any number?
Answer:
75% can be converted into a decimal, any percentage can.
Once converted, 75% is actually .75
At this point you can move the decimal place two place up, and put it over 100, in a fractal form
75/100
You can then simplify this to
3/4
You can then use this fraction as a conversion factor with any number, for example if we took the number 8
8∗3/4
2∗3/1=6
Solve for n: 9^(n-1) = (1/3)^(4n-1) Show your work.
Answer:
n=1/2 after being simplified
Step-by-step explanation:
Use Division Distributive Property:
9^n-1=1/3^4n-1 then convert both sides to the same base
3^2(n-1) = 3^-(4n-1)
cancel the base of 3 on both sides
2(n-1) = -4n+1
then expand 2n-2=-4n+1
add 2 to both sides 2n=4n+1+2
simplify: -4n+1+2 to -4n+3
2n=-4n+3
add 4n to both sides: 2n+4n=3
simplify: 2n+4n to 6n
6n=3
divide both sides by 6
n=3/6
simplify and n=1/2
PLSSSSS HEEEELP MEEEE :<
Answer:
x=22
Step-by-step explanation:
From the theorem of Z angles you can find that the sum of both given angles must equal 180.
So solve: 2x-26 + 7x+8 = 180
Simplify:
9x -18 = 180
9x = 198
x = 198/9 = 22

Ms. Janis teaches math to 254 students each day. she grades one paper for each student each day. if Ms. Janis teaches for 25 days this month, how many papers does she grade?
please help me
Answer:
6,350
Step-by-step explanation:
254 times 25 is 6,350
Answer:
6350 Papers
Step-by-step explanation:
254 x 2 = 508
508 x 10 = 5080
(This is basically 254 x 20)
254 / 2 = 127
127 x 10 = 1270
(This is basically 254 x 5)
5080 + 1270 = 6350
Write x > 6 in interval notation.
Answer:
x > 6 in interval notation is: (6, ∞)
NOTE:
Interval notation is a way to represent an interval as a set of numbers. The numbers are the endpoints of the interval.
-----
Build the interval notation for x:
Since you did not enter an equal sign, this translates to ( since we will not be including the number 6
Based on the > you entered, the right side of the interval notation will extend to positive infinity, which is denoted as +∞
(6,+∞)----- (answer)
Set Builder Notation for x:
{ x | x>6 } where | denotes such that

Which one of the following values of k makes the trinomial 9x^2 + kx + 64 a perfect square
a 24
b 48
c 16
d 42
Answer:
it is C 16
Step-by-step explanation:
x² - kx + 64
Since we are looking for a perfect square, then we need to take the square root of 64 to find the factors: √64 = 8
So, the factors are: (x - 8)(x - 8)
Foil (or distribute) to get: x² - 16x + 64 The k-value is 16
Matthew is taking a multiple choice test with a total of 40 points available. Each question is worth exactly 2 points. What would be Matthew's test score (out of 40) if he got 9 questions wrong? What would be his score if he got xx questions wrong?
Answer:
22 points
Step-by-step explanation:
If their are fourty points avaliable and each question is worth two points, then there are a total of twenty questions (20 times 2 is 40). Therefore, if he gets nine questions wrong, he would have gotten 11 right. Because we know that each question is two points, we may just multiply 11 by 2, which means he has gotten a score of 22 points!
Consider the line with equation y=-2x + 2.
Can you write the equation of a line through
point (3,-4) that is perpendicular to the given line?
Answer:
[tex]m_{1} \times \frac{1}{m_{2}} = - 1 \\ m_{2} = \frac{1}{2} \\ \frac{1}{2} = \frac{y + 4}{x - 3} \\ 2y + 8 = x - 3 \\ 2y = x - 3 - 8 \\ 2y = x - 11 \\ y = \frac{1}{2} x - \frac{11}{2} [/tex]

Answer:
1. Neither
2. Odd
3. Odd
4. Even
Step-by-step explanation:
Graphically, an equation is even if it is symmetrical across the y-axis. An equation is odd if it is symmetrical after folded over y and x. An equation is neither if it fulfills neither requirement.
Algebraically, an equation is even is f(x) = f(-x), and an equation is odd if f(-x) = -f(x).
Hope it helps :) and let me know if you want me to elaborate.

Identify the domain of the exponential function shown in the following graph: (2 points)
Answer:
x is greater than or equal to 0.
Step-by-step explanation:
The domain is just your X value. In contrast, the range is your Y value. Since we start at and include 0 on the X axis, we continue forever from there. Therefore, X is greater than or equal to 0.

A rectangle has a perimeter of 36 cm. Its width is 4 cm less than its length. Find
the length and width of the rectangle.
Answer:
14
Step-by-step explanation:
Perimeter = 2 x length + 2 x width = 2L + 2w
Width is 4 cm less than the length, so w = L-4
36 = 2L + 2(L-4)
36 = 2L + 2L - 8
36 = 4L - 8
44 = 4L
L = 11
w = 7
2(11) + 2(7) = 22 + 14 = 36
Length is 11, width is 7
