If A = -x + 2x - x + 1 and B = x² + 5, find A + B.
Answer:
6 + x^2
Step-by-step explanation:
Plug in the values for A and B.
(-x + 2x - x + 1) + (x^2 + 5)
Remove the parenthesis. Combine like terms.
-2x + 2x = 0
1 + x^2 + 5
Combine like terms again.
6 + x^2

Find the value of x. Round to the nearest tenth
Step-by-step explanation:
use cos since we're given the adjacent and asked to find the hypothenus.
cos 33° = 6/x
cross multiply
xcos33° = 6
divide both sides by cos 33°
(cos 33 is approximately 0.8387)
then x = 7.15
Answer:
[tex]x \approx 7.2[/tex]
Step-by-step explanation:
The given triangle is a right triangle this is indicated by the box around one of its angles, signifying that the angle is a right angle. One of the properties of a right triangle is the right angle trigonometric ratios. these are a series of ratios that relate the sides and angles of a right triangle. Such ratios are as follows:
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]
Please note that the sides named ([tex]opposite[/tex]) and ([tex]adjacent[/tex]) Are subjective and change based on the angle by which one refers to. However the side ([tex]hypotenuse[/tex]) indicates the side opposite the right angle, this side does not change its name.
In this case, one is given a (33) degree angle, and the measure of the side adjacent to is, (6). One is asked to find the measure of the hypotenuse (x). It would be most logical to use the ratio of cosine (cos). Substitute the given values in and solve for (x).
[tex]cos(\theta)=\frac{adjacent}{hypotenuse}[/tex]
[tex]cos(33)=\frac{6}{hypotenuse}[/tex]
Inverse operations,
[tex]cos(33)=\frac{6}{hypotenuse}[/tex]
[tex]hypotenuse=\frac{6}{cos(33)}[/tex]
[tex]hypotenuse \approx 7.15[/tex]
Use a calculator to find the mean of the
data. {22.1, 23.8, 20, 23.3, 20.2, 24.2, 21.8, 22.7, 21.2, 21.3, 21.7, 23.2, 19.1, 22.3, 22.1, 20.9, 20.7, 20.2, 23.3, 19.6, 20.7,
24.5}
The mean of the data is 21.6.
What is mean?The mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations).
Given data
{22.1, 23.8, 20, 23.3, 20.2, 24.2, 21.8, 22.7, 21.2, 21.3, 21.7, 23.2, 19.1, 22.3, 22.1, 20.9, 20.7, 20.2, 23.3, 19.6, 20.7, 24.5}
Sum of observations = 22.1 + 23.8 + 20 + 23.3 + 20.2 + 24.2 + 21.8 + 22.7 + 21.2 + 21.3 + 21.7 + 23.2 + 19.1 + 22.3 + 22.1 + 20.9 + 20.7 + 20.2 + 23.3 + 19.6 + 20.7 + 24.5 = 478.9
Number of observations = 22
Mean = [tex]\frac{Sum \ of \ observations}{Number \ of \ observations}[/tex]
Mean = [tex]\frac{478.9}{22}[/tex] = 21.6
The mean of the data is 21.6.

What is x+y
Explain your answer
Answer:
x + y = 0
Step-by-step explanation:
The problem states that variables x and y are the same distance away from 0 on the number line. Since x is at 4, it is 4 units away from 0. Assuming that x and y cannot be the same number, y would have to be at -4, because that is the only other number besides 4 that is 4 units away from 0.
If x and y can be the same number another possibility would be that y is also 4 making x + y = 8.
an obtuse angle is an angle which is _______
Answer:
an obtuse angle is an angle that is more than 90 degrees
Step-by-step explanation:
Which models show 60%? Check all that apply.
Answer:
OPTION A AND B.
AS OPTION A IS 3/5=6/10=60%
Option C=60/100=60%
Answer:
the first and the last option
Step-by-step explanation:
In the first option 3/5 of the rectangle are filled in. if you divide 3 by 5, you will get 0.6, which when converted in to percent is equal to 60%
3/5 = 0.6
0.6 = 60%
*to convert decimals into percent, you just have to move the decimal point 2 places to the right and add the present sign*
in the second option 5 out of the 10 rectangles inside the square are filled in. that means that 5/10 of the square are filled in, the model shows 50%
5/10 = 1/2 = 0.5 = 50%
in the third model 6 out of the 10 rows in the square are filled in. that means that 6/10 of the square are filled in which is equal to 60%
6/10 = 0.6 = 60%

ax-76 = 9c
i’m confused bc it doesn’t tell me what i’m solving for. please help! thank you!
Answer:
Step-by-step explanation:
Probably it's asking for x so you have to find x in term of a and c
ax = 9c+76
x = 9c+76/a
Answer:
Step-by-step explanation:
I can see your problem. That's one of those questions where the directions are part of the problem. I think you are supposed to solve for x.
ax-76 = 9c Add 76 to both sides
ax = 9x + 76 Divide by a
x = (9x + 76)/a
f (x) = -x^2 + x + 14 Find f(2)
f(x) = -x² + x + 14
f(2) = -2² + 2 + 14 = -4 + 16 = 12
f(2) = 12
Answer:
12
Step-by-step explanation:
f (x) = -x^2 + x + 14
Let x= 2
f(2) = - (2)^2 +2+14
= -4 +2+14
= -2 +14
= 12

Geometry - Triangle d) In the given figure, BE = EC and CE is the bisector of ZACB. Prove that ZBEC = ZACD. E B D С
Answer:
Let m∠BCE = x
Then m∠ACE = x as well since CE is bisecting ∠ACB.
m∠ACD + x + x = 180° ⇒ m∠ACD = 180° - 2xConsider ΔBEC
Since BE = EC, the opposite angles are congruent:
∠BCE ≅ ∠CBEThen:
m∠CBE = m∠BCE = xFind the angle BEC:
m∠BEC = 180° - (x + x) = 180° - 2xComparing the above we see that:
m∠BEC = m∠ACDprovedI WILL GIVE BRAINLIEST!! NO LINKS PLZ

10) 87.5%
11) 2.64
12) 25%
13) 5.7
14) 85%
16) 75%
Step-by-step explanation:
2) 9 = 20% of x
9 * 5 = 45
3) 8% of x = 2
12.5 * 2 = 25
4) 39 = x(78)
39/78 = 1/2 = 50%
5) x(36) = 12
12/36 = 1/3 = 33.3...%
6) x = 0.8(22)
22/10 = 2.2
2.2* 8 = 16 + 1.6 = 17.6
7) 55 = 0.11(x)
55/11 = 5
5 * 100 = 500
8) 7/20 = 35/100 = 35%
9) 27 = 0.45(x)
27/45 = 3/5
3/5 * 100 = 300/5 = 60
10) . 49/56 = 7/8 = 0.875 = 87.5%
11) 6/100 = 0.06
0.06 * 44 = 2.64
12) 48/192 = 6/24 = 1/4 = 25%
13) 95/100 = 0.95
0.95 * 6 = 5.40 + 0.3 = 5.7
14) 68/80 = 34/40 = 17/20 = 85%
16) 108/144 = 9/12 = 0.75 = 75%
