Solve the equation.
3m= 5(m + 3)-3
HELP
Answer:
m = -6
Step-by-step explanation:
3m= 5(m + 3)-3
Distribute
3m = 5m +15 -3
Combine like terms
3m = 5m +12
Subtract 5m
3m-5m = 5m+12-5m
-2m = 12
Divide by -2
-2m/-2 = 12/-2
m = -6

The value pi/16 is a solution for the equation 2cos^2(4x)-1=0
True or false?
Answer:
True
Step-by-step explanation:
The other person is wrong
The value π/16 is a solution for the equation 2cos²(4x) – 1 = 0, is true.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The value π/16 is a solution for the equation 2cos²(4x) – 1 = 0.
Put x = π/16, we have
2cos²(4x) – 1 = 0
2cos²[4 (π/16)] – 1 = 0
2cos²(π/4) – 1 = 0
We know that cos (π/4) = 1/√2
2(1/√2)² – 1 = 0
2 (1/2) – 1 = 0
1 – 1 = 0
0 = 0
Thus, the statement is true.

What is the inverse function of f(x) = x/x-2
Answer:
The answer is:
y = x/x −2
Answer:[tex]f^{1}=\frac{2x}{x-1}[/tex]
Step-by-step explanation:
Write f(x) =x/x-2 as an equation
[tex]f(x)=\frac{x}{x-2}[/tex]
Interchange the variables
[tex]x=\frac{y}{y-2}[/tex]
solve for y, multiply equation by y-2.
[tex]y=\frac{2x}{x-1}\\[/tex]
replace y with [tex]f^{1}[/tex](x)
you get the above answer.

The table below shows the amount paid for different numbers of items. Determine if this relationship forms a direct variation. Verify your answer.
Direct variation occurs when a variable varies directly with another variable. That is, as the x-variable increases, the y-variable also increases.
The ratio of between y-variable and x-variable would be constant.
Direct variation can be represented by the equation, [tex] y = xk [/tex], where k is a constant. Thus,
[tex] \frac{y}{x} = k [/tex]
From the table given, it seems, as x increases, y also increases. Let's find out if there is a constant of proportionality (k).
Thus, ratio of y to x, [tex] \frac{0.50}{1} = 0.5 [/tex]
k = 0.5.
If the given table of values has a direct variation relationship, then, plugging in the values of any (x, y), into [tex] \frac{y}{x} = k [/tex], should give us the same constant if proportionality.
Let's check:
When x = 2, and y = 1:
[tex] \frac{y}{x} = k [/tex],
[tex] \frac{1}{2} = 0.5 [/tex],
When x = 3, y = 1.5:
[tex] \frac{1.5}{3} = 0.5 [/tex],
When x = 5, y = 2.50:
[tex]\frac{2.5}{5} = 0.5[/tex],
The constant of proportionality is the same. Therefore, the relationship forms a direct variation.
Answer:
Direct variation occurs when a variable varies directly with another variable. That is, as the x-variable increases, the y-variable also increases.

Lin’s uncle is opening a bakery. On the bakery’s grand opening day, he plans to give away prizes to the first 50 customers that enter the shop. Every fifth customer will get a free bagel. Every ninth customer will get a free blueberry muffin. Every 12th customer will get a free slice of carrot cake.
1. Diego is waiting in line and is the 23rd customer. He thinks that he should get farther back in line in order to get a prize. Is he right? If so, how far back should he go to get at least one prize? Explain your reasoning.
2. Jada is the 36th customer.
a. Will she get a prize? If so, what prize will she get?
b. Is it possible for her to get more than one prize? How do you know? Explain your reasoning.
3. How many prizes total will Lin’s uncle give away? Explain your reasoning.
Answer:
1. Yes, 1 position backwards
2. Yes, a free blueberry muffin and a free slice of carrot cake
b. Yes
3. 19 prizes
Step-by-step explanation:
The given conditions for winning a prize are as follows;
The prize that every 5th customer gets = A free bagel
The prize that every 9th customer gets = A free blueberry muffin
The prize that every 12th customer gets = A free slice of carrot cake
Therefore, the prizes will go to the 5th, 9th, 10th, 12th, 15th, 18th, 20th, 24th, 25th, 27th, 30th, 35th, 36th, 40th, 45th, 48th, and 50th positon customers
1. Diego being 23rd is right for thinking that he should get farther back in line in order to get a prize
He should get one position behind to 24th position
The reason is because prizes will be given to every 12th customer, and the 24th customer is the second 12th customer
2. Yes Jada will get a price as her position corresponds to the consecutive 9th and 12th customers position
Jada will get a free blueberry muffin and a free slice of carrot cake
b. It is possible for Jada to get more than one prize
This is so because her position coincides with the consecutive 9th and 12th customers position
3. The number prizes that Lin's uncle gives away are;
5th, 9th, 10th, 12th, 15th, 18th, 20th, 24th, 25th, 27th, 30th, 35th, 36th, 40th, 45th, 48th, and 50th = 17 prizes
including 1 extra prize each for the 36th and 45th customers which gives a total of 19 prizes.

It is the parallelogram that has its unequal contiguous sides and the four right angles. A) Square B) Rhombus C) Rectangle D) Rhomboid
Answer:
Rhomboid is the parallelogram that has its unequal contiguous sides and the four right anglesHope it helps you Mark it as brainliest and follow me My account you can see here below (hardik 60)pls help me .question no 14
Question 14, Part (i)
Focus on quadrilateral ABCD. The interior angles add to 360 (this is true for any quadrilateral), so,
A+B+C+D = 360
A+90+C+90 = 360
A+C+180 = 360
A+C = 360-180
A+C = 180
Since angles A and C add to 180, this shows they are supplementary. This is the same as saying angles 2 and 3 are supplementary.
==================================================
Question 14, Part (ii)
Let
x = measure of angle 1
y = measure of angle 2
z = measure of angle 3
Back in part (i) above, we showed that y + z = 180
Note that angles 1 and 2 are adjacent to form a straight line, so we can say
x+y = 180
-------
We have the two equations x+y = 180 and y+z = 180 to form this system of equations
[tex]\begin{cases}x+y = 180\\y+z = 180\end{cases}[/tex]
Which is really the same as this system
[tex]\begin{cases}x+y+0 = 180\\0+y+z = 180\end{cases}[/tex]
The 0s help align the y terms up. Subtracting straight down leads to the equation x-z = 0 and we can solve to get x = z. Therefore showing that angle 1 and angle 3 are congruent. We could also use the substitution rule to end up with x = z as well.
Hector is flying a kite. He has let out 86 feet of string and is holding it 4 feet off the ground. If the string is at an angle of elevation of 42°15'30", how high is the kite?
Answer:
h = 61.83 feet
Step-by-step explanation:
length of string from Hector to kite = c = 86 feet.
and 4 feet off the ground.
angle A = 42° 15' 30"
req'd: how high is the kite?
angle A = 42° + 15' (1° / 60') + 30"(1° / 3600'')
angle A = 42.26
to get the side a (height of kite) 4 feet above ground: use Sin(A) = opp / hyp
Sin(A) = a / c
Sin(42.26) = a / 86
a = Sin(42.26) * 86
a = 57.83 feet
therefore, the height of the kite from the ground = h = 57.83 + 4
h = 61.83 feet

Answer:
1). |(-3) - 8|
2). 11 units
Step-by-step explanation:
If the given numbers are 'x' and 'y', distance between these numbers will be represented by the absolute value expression,
Distance = |x - y|
Given numbers are (-3) and 8.
Therefore, expression for the distance between these points will be,
Distance = |(-3) - 8|
Distance between these points will be = 11 units
What is the slope of the line given by the equation y = 4x +12?
Answer:
4
Step-by-step explanation:
The equation of a line can be written as y = mx + b where m is the slope.
In this case, m = 4 since the equation is y = 4x + 12.
Answer: The slope is 4
Step-by-step explanation:
The slope of a y intercept form equation which uses the formula y=mx+b is the number acting as the coefficient.
Write an equation of the line that passes through the origin and
is parallel to the line whose equation is y = 3x - 7.
Answer:
y = 3x
Step-by-step explanation:
Parallel lines have the same slope, so the slope of this new line will be the same as the given one.
For a line to pass through the origin it needs to have a y intercept of 0, because the origin is the point (0,0).
Answer:y = 3x

yaa is 10 years kwasi is 20 years and they share 60 mangoes and to a ratio of their ages find what each of them will get
Step-by-step explanation:
Yaa's age = 10 years
Kwasi's age = 20 years
They share the mangoes in the ratio of their ages
That's
10 : 20 = 1 : 2
Total number of mangoes = 60
Total parts = 1 + 2 = 3
Yaa's share[tex] \frac{1}{3} \times 60[/tex]= 20 mangoesKwasi's share[tex] \frac{2}{3} \times 60[/tex]= 2 × 20
= 40 mangoesHope this helps you
Answer:
Yaa gets 20 oranges while Kwasi gets 40 oranges
Step-by-step explanation:
We will add both ages= 10+20=30
Then we will pick yaa's age/ their total ages multiplied by the amount of oranges= 10/30 * 60
yaa will get= 600/30 = 20 oranges
Then Kwasi's age/their total ages multiplied by the amount of oranges= 20/30* 60=
1200/30= 40 oranges
