Answer:
so, with terms like -3x and -8x remember to keep the negative or positive sign the same when combining like terms.
in this instance the simplified expression would be:
15 - 11x
because -3x - 8x = -11x
does this make sense? lmk if u need help
Given the equation y= -3x + 2.5 . When y is 8.5 , what value of x makes the equation true?
Answer:
x = -2
Step-by-step explanation:
y = -3x + 2.5
if y = 8.5 then:
8.5 = -3x + 2.5
-3x = 6
x = -2

4. For which of the following probability assignments are events A and B independent?
P(AN B“) – 0.3. P(AN B) = 0.12, and P(Aºn B) = 0.4.
B
P(An BC) = 0.3. P(An B) = 0.3, and P(Aºn B) = 0.3.
C) P(An Bº) = 0.1. P(ANB) = 0.1, and P(Aº n B) = 0.4.
P(An Bº) = 0.3. P (AnB) = 0.0, and P(
AB) = 0.2.
E) P(An Bº) = 0.5, P (ANB) = 0.1 and P (Aºn B) = 0.4
Answer:
A
Step-by-step explanation:
formatting is so bad lol
but yeah its the first one because for independent events, the probably of a and b is the product of both probabilities, just like how 0.3*0.4=0.12

Quadrilateral BCDE is inscribed in circle A. The measure of ⏜ is 73°. The measure of ⏜ is 53° and the measure of ⏜ is 102°.
Determine the measure of ∠ BCD.
Answer:
117
Step-by-step explanation:
Angle BCD intercepted arc is Arc DEB.
We know DE measure but we need to find EB measure.
Since a circle circumference add up to 360, we can add all of the known arcs up to 360 to find the missing arc.
[tex]73 + 53 + 102 + x = 360[/tex]
[tex]126 + 102 + x = 360[/tex]
[tex]228 + x = 360[/tex]
[tex]x = 132[/tex]
So arc EB measure 132.
Arc eb and de.
132+102=234.
Angle BCD is inscribed angle of Arc DEB, so that means angle BCD is half of Arc DEB.
[tex] \frac{234}{2} = 117[/tex]
lemme just vent real quick. i do flvs. im almost a straight A student. for the most part. i've litterly been doing this flvs math exam all day. 2 parts btw. i flunked the first one, and i got a 50. im just dying too see what i get now. ive already asked like 3 questions on here, but they havent been answered. feel free to go look at them. if you've read this far, go get some points. :D thanks for reading.

3w - 10>-4
Answer:
If your trying to find w then it'll be 2
Step-by-step explanation:
3w - 10 > -4
+10 +10
3w > 6
3 3
w > 2
So I added 10 on both sides and guess positive 10 is bigger than -4, it'll be a positive 6. Then I divide 3 on both sides after I got 6 and thats how I got 2

Identify the vertex of the parabola and tell whether it is a minimum or a maximum.
Answer:
First parabola's vertex is (-2,2), which is a minimum.
Second parabola's vertex is (3,2), which is a maximum.
Step-by-step explanation:
Simply, a vertex of a quadratic is a graph's turning point.
The maximum and minimum can be identified by seeing if the graph curves up or down.
Maximum occurs when your graph is facing down.
Minimum occurs when your graph is facing up.

What is the difference in area between a circle with a diameter of 3 meters and a square with a side length of 3 meters? Use 3.14 for pie.
pls help me
Answer:
The area of a circle with a diameter of 3 meters:
A = πr² = π(d/2)² = 3.14(3/2)² = 7.065 m²The area of a square with a side length of 3 meters:
A = a² = 3² = 9 m²The difference:
9 - 7.065 = 1.935 m²The square has greater area by 1.935 m²
Answer:
the difference in area between a circle with a diameter of 3 meters and a square with a side length of 3 meters=d²-π/4d²
=3²-3.14/4×3²=1.935m²

In ΔSTU, the measure of ∠U=90°, TS = 65, UT = 56, and SU = 33. What ratio represents the cosine of ∠S?
Answer:
33/65
Step-by-step explanation:
Given the following
∠U=90°,
TS = 65 = HYpotenuse
UT = 56 = Opposite
SU = 33 = Adjacent
Cos <S = adj/hyp
Cos <S = SU/TS
Cos <S = 33/65
Hence the required ratio is 33/65

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Answer:
Let's solve your equation step-by-step.
11x − 2x + 15 = 8 + 7 + 9x
Step 1:
Simplify both sides of the equation.
11x − 2x + 15 = 8 + 7 + 9x
11x + −2x + 15 = 8 + 7 + 9x
( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )
( Combine Like Terms )
9x + 15 = 9x + 15
9x + 15 = 9x + 15
Step 2:
Subtract 9x from both sides.
9x + 15 − 9x = 9x + 15 − 9x
15 = 15
Step 3:
Subtract 15 from both sides.
15 − 15 = 15 − 15
0 = 0

A stadium has seating accommodation for 3800 people. At a cricket match all seats were taken. If there were 5609 people attending the match, how many people didn't have seats?
Answer:
Step-by-step explanation:
Those standing is the same thing as people who didn't have seats.
Those standing = the total number of people attending - those seated.
Those standing = 5609 - 3800
Those standing = 1809

One method that meteorologists could use to find the height of a layer of clouds about the ground is to shine a bright spotlight directly up onto the cloud layer and measure the angle of elevation from a known distance away. Find the height of the cloud layer in the diagram to the nearest tenth
Answer:
367.6 mStep-by-step explanation:
Use trigonometry
Let the height of the cloud be x, then we have:
tan 35° = x/525x = 525 tan 35°x = 367.6 (rounded)The height of the cloud layer is 367.6 m
