2(3x+2)=6x+4 linear equations
Answer:
0 or 6x+4=6x+4 (Technically no slope at all!!)
Step-by-step explanation:
You need to do distributive property and then solve for x!!
meaning the 2(3x+2) has to get distributive property process.
6x+4=6x+4
That shall be equal together!!! (You could stop here!!)
If continue:
6x-6x=4-4

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form.
12, 10, 8,.........
This is______sequence and the _______is equal to _________.
Answer:
Step-by-step explanation:
This is an arithmetic sequence and the common difference = - 2
You might be a little puzzled by the minus sign in front of the two. You can look at the sequence for the answer. It is going down. A plus 2 would make it go up. Minus signs are always a bit tricky and you have to watch out what you do with them. But the rule is simple
a minus common difference produces a sequence that goes down.a plus common difference produces a squence that goes up.You know that this is an arithmetic sequence because the common difference can be found by adding or subtracting a number from the previous term to get to the next term.
A geometrice sequence would use multiplication or division to get from one term to the next.

What may possibly come out of a function is called the Codomain.
What actually comes out of a function is called the Range.
Range is all the possible values of 'y'.
When we observe the graph, the smallest value of 'y' is 20, where the point is (6, 20), and the largest value of 'y' is 60, where the point is (1, 60).

Explanation for statement 3 :
Suppose The number of shoppers on Saturday is 100 and the number of shoppers on Sunday is 200
Total number of shoppers = 300
On Saturday :
Q₃ = 70 then 25% of shoppers spent more then $70
then 25 shopper spent more then $70
On Sunday:
M’ = 70 then 50% of shoppers spent more then $70
then 100 shopper spent more then $70
On both days:
(100+ 25) shopper spent more then $70
Then 125 shopper spent more then $70
But 125 is not 75% of 100+200=300

Answer:
12 years old
Step-by-step explanation:
3x+5=41
3 times a number and 5 more
'more' usually means adding
41-5 =36
36/3 =12
Answer:
Equation: 41 = 3x + 5
x = 12
Step-by-step explanation:
Hello!
Betty is 5 more than 3 times Jadyn's age. Since Jadyn's age is unknown, we'll call that unknown variable x.
Betty is 5 more than 3 times x. Betty is also 41 years old.
Equation: 41 = 3x + 5
Now we have to solve for x
Solve for x:
41 = 3x + 536 = 3xx = 12
Jadyn is 12 years old.
The blueprint for the Moreno's living room has a scale of . The family wants to 2 inches= 3 feet use a scale of 1 inch =4 feet. What is the width of the living room on the new blueprint?
Answer:
If I am understanding the question correctly, every 6 feet in real life will be equivalent to 1 inch "on paper", or in the blueprint. Using dimensional analysis, which is a methodology for converting from one unit to another, we have:
18 feet * 1 inch / 6 feet = 3 inches
On the other axis,
24 feet * 1 inch / 6 feet = 4 inches
Therefore, the blueprint for this 18x24 foot room, with a scale of 6 feet:1inch, should be 3x4 inches.

If the zeros of a quadratic function, F, are -2 and 4, what is the equation of the axis of symmetry of F
Answer:
x=1
Step-by-step explanation:
if the zeroes are (-2,0) and (4,0), then the axis of symetry is going to be right in the middle of those two, with the graph reflected equally on either side.
so you get:
(4-2)÷2=1
therefore the equation of the axis of symetry is x=1

3) You need to paint shutters on a window that is on the second floor of your house. You have a 20 foot ladder that you will use. There is a warning on the ladder that states the angle formed by the ladder and the ground must not be less than 70 degrees, or the ladder may slip and cause serious injury or death. You planned on placing the bottom of the ladder 3 feet from the base of the house. Will the angle formed between the ground and the ladder be safe? What is the furthest possible distance the ladder can be placed to maintain a safe angle? Sketch:
Answer:
See below ↓↓
Step-by-step explanation:
Height of ladder = 20 feetDistance of base of ladder from house = 3 feetAngle must not be < 70°Taking the cos ratio of the angle
Let the angle formed be α cos α = adjacent side / hypotenusecos α = 3 / 20 = 0.15α = cos⁻¹ (0.15)α = 81.37°⇒ The angle formed is safe
Finding furthest possible distance
Take α to be 70°cos 70° = 0.34 = x/20⇒ x = 20 x 0.34 = 6.8 feetAnswer:
Yes, the angle formed between the ground and the ladder is safe
6.84 ft (nearest hundredth)
Step-by-step explanation:
We can use the cos trig ratio to determine the angle made between the 20ft ladder and 3ft from the base of the house (see first attached image for sketch).
[tex]\sf \cos(\theta)=\dfrac{A}{H}[/tex]
where:
[tex]\theta[/tex] is the angleA is the side adjacent to the angleH is the hypotenuseGiven:
A = 3 ftH = 20 ft[tex]\sf \implies \cos(\theta)=\dfrac{3}{20}[/tex]
[tex]\sf \implies \theta=\cos^{-1}\left(\dfrac{3}{20}\right)[/tex]
[tex]\sf \implies \theta=81.37307344..^{\circ}[/tex]
Therefore, as the ladder is forming an 81.37° angle and 81.37...° > 70° the angle formed between the ground and the ladder is safe.
To find the furthest possible distance the ladder can be placed, set [tex]\theta[/tex] to 70° (max safe angle) and the hypotenuse (ladder length) to 20, then solve for A (see second attache image for sketch):
[tex]\sf \implies \cos(70^{\circ})=\dfrac{A}{20}[/tex]
[tex]\sf \implies A=20\cos(70^{\circ})[/tex]
[tex]\sf \implies A=6.840402867...\: \sf ft[/tex]
So the furthest possible distance the ladder can be placed to maintain a safe angle is 6.84 ft (nearest hundredth).

what is the angle of BTC, Angle TBC,Angle TCB
By geometric and algebraic properties the angles BTC, TBC and TBC from the triangle BTC are 128°, 26° and 26°, respectively.
How to determine the angles of a triangle inscribed in a circle
According to the figure, the triangle BTC is inscribed in the circle by two points (B, C). In this question we must make use of concepts of diameter and triangles to determine all missing angles.
Since AT and BT represent the radii of the circle, then the triangle ABT is an isosceles triangle. By geometry we know that the sum of internal angles of a triangle equals 180°. Hence, the measure of the angles A and B is 64°.
The angles ATB and BTC are supplmentary and therefore the measure of the latter is 128°. The triangle BTC is also an isosceles triangle and the measure of angles TBC and TCB is 26°.

Let's first try to figure out the whole. Looking at the number line, we can see that the shaded portion of the box goes up to 2 1/3. So, this is our first number.
Then, we need to figure out what 2 1/3 was divided by. This is pretty obvious from the groupings on the box. 2 1/3 was divided by 2/3.
2 1/3 divided by 2/3 = ?
Once again using the box and the groupings, we can see that 2/3 goes into 2 1/3 evenly 3 times, leaving 1/3 left over.
2 1/3 divided by 2/3 = 3 1/2
Correct Answer: A
