Two angles are supplementary if their measures add up to 180°. If one of two supplementary angles is (3x + 7)° while the other is (5x - 11), then x =
A.25
B.21
C.24
D.20
E.23
Answer:
E. 23
Step-by-step
3x + 7 + 5x - 11 = 180
* add 3x and 5x
8x + 7 - 11 = 180
* do 7-11
8x - 4 = 180
* add 4 to both sides to cancel it out
8x = 184
* divide 8 on both sides to get x alone
x = 23
what is the area of the figure below
A: 88in2
B: 48 in2
C: 68 in2
B:43in2
Answer:
The correct answer is C, 68in².
Answer:
68
Step-by-step explanation:
The are of the square is 3*3 = 9
Since we have two squares we need to mulitply by 2
9*2 = 18 is the total area of the squares
if you draw a line from the one square to the other you make a rectangle in the middle
the are of the rectangle is 10*3 which is 30
Two triangle has appared as we draw the line from one square to the other square.
The height of the traingle is (7 - 3)/2 which is 2
(2*10) / 2 = which is 10
Since we have 2 triangle we get result as 2*10 = 20
20+30+18 = 68

Given point P(9,-11), what are the coordinates of P' after a 180⁰ rotation?
(9,11)
(-9,11)
(-11,-9)
(11,9)
Answer:
-9,11
Step-by-step explanation:
The negative signs get flipped so if the number was positive it would become negative and vice versa.
Answer:
(-9,11)
Step-by-step explanation:
180 Degree Rotation
When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.

Which linear equation matches this graphed line?
y = 2x + 5
y = 1/2x-5
y = 2x+5
y = 1/2x + 5
Answer:
I think one of the choices was entered incorrectly. You have y=2x+5 listed twice. I believe the answer is y=-2x+5
Step-by-step explanation:
5 is the y-intercept and it is a +5 because it is above the x-axis. Slope = rise/run. In this case the slope should be negative thus -2x. Hope this helps.

-4.8 (6.3x-4.18)=-58.56 what is x?
Answer:
x = 2.825
Step-by-step explanation:
-4.3(6.3x + -4.18) = -58.56
-4.3(-4.18 + 6.3x) = -58.56
(-4.18 * -4.3 + 6.3x * -4.3) = -58.56
(17.974 + -27.09x) = -58.56
17.974 + -27.09x = -58.56
17.974 + -17.974 + -27.09x = -58.56 + -17.974
0.000 + -27.09x = -58.56 + -17.974
-27.09x = -58.56 + -17.974
-27.09x = -76.534
x = 2.825175341
Terry flips a coin 150 times.Make a prediction that the coin will come up tales
A Exactly 300
B Close to but not exactly 300
C Exactly 75
D Close to but not exactly 75
Answer:
its either C or D
Step-by-step explanation:
there are 2 possible outcomes for getting either heads or tails so if we divided 150 by 2 we get 75, so about 75 times you could get tails.
so maybe it is D, but im not sure
Can somebody help me on this
Answer/Step-by-step explanation:
a. 3x + 13 = 12x - 2x
Add like terms
3x + 13 = 10x
3x = 10x - 13 (subtraction property of equality)
3x - 10x = - 13 (substraction property of equality)
-7x = -13
-7x = -13/-7 (division property of equality)
x = 13/7
b. 6j - 12 + 4j - 8 = 10
Add like terms
6j + 4j - 12 - 8 = 10
10j - 20 = 10
10j = 10 + 20 (addition property of equality)
10j = 30
10j/10 = 30/10 (division property of equality)
j = 3
c. 10y - 4y = 14 + 2y - 3y
Add like terms
6y = 14 - y
6y + y = 14 (addition property of equality)
7y = 14
7y/7 = 14/7
y = 2
d. 4p + 8 - 3p = 33
Add like terms
4p - 3p + 8 = 33
p + 8 = 33
p = 33 - 8 (subtraction property of equality)
p = 25

A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 95,000 fish. Due to population decreases, the number of fish the company was able to catch decreased by 4% each year. How many total fish did the company catch over the first 14 years, to the nearest whole number?
Answer:
54,265 fishes
Step-by-step explanation:
The formula for Population decrease =
P(t) = Po × e^-rt
Where
P(t) = Population after time t
Po = Initial population = 95000
r = decrease rate = 4% = 0.04
t = time in years = 14
Hence
P(t) = 95,000 × e ^- 0.04 × 14
P(t) = 95,000 × e^-0.56
P(t) = 54264.861066 fishes
Approximately = 54,265 fishes
The total fish the company caught over the first 14 years, to the nearest whole number is 54,265 fishes
Mrs. Garcia borrowed some money at the rate of 4% per annum for the first year, at the rate of 6% pe r annum for the next 2 years, and at the rate of 7.5% per annum for the period beyond 3 years. If he pays a total interest of ₱ 15 750 at the end of 5 years, how much money did he borrow?
Answer: ₱40,909.1
Step-by-step explanation:
Given data:
Rate for first year = 4%
Rate for next two years = 6%
Rate for the next 3 years = 7.5%
Interest paid back after 5years = ₱ 15,750
Solution:
How much did she borrow.
= let the sum borrowed be P
= P * 4 / 100
= 4P/100
= 1P/25.
For the next two years
= P* 6 * 2/100
= 12P/100
= 3P/25
For the next 3years
= P* 7.5*3/100
= 22.5P/100
= 9P/40.
1P/25 + 3P/25 + 9P/40 = 15750
77P/200 = 15750
P = 15750 * 200 / 77
P = 315,0000/77
P = ₱40,909.1
The amount borrowed is ₱40,909.1
f(x) =∛2x g(x)=2x+1 Find (f/g) (x) Include any restrictions on the domain
Answer: ∛2x / 2x+1
x cannot equal -1/2
Step-by-step explanation: f/g means we divide the f function by the g function
so that’s all we do!
then, remember, we can’t divide by 0. so 2x+1 can’t be 0. if we solve that out, we get that x can’t be -1/2, because that would make it 0. there’s our domain restriction!
