Which is the correct algebraic expression for "6 less than 3 times a number?
Answer: [tex]\huge\boxed{\ m=7 }[/tex]
Step-by-step explanation: We can break this problem down to understand it. Let the number be m. Three times the number 'm ' is 3.m or 3m. 3 ( m ) - 6 = 15. 3m -6 = 15 add 6 to both sides; 3m -6 + 6 = 15 + 6 3m = 21 dividing both the sides by 3 ,and we get; 3m /3 = 21 / 3 m=7 .

= Number of visitors × visitors purchased guide books
= 550 × 3 ÷ 5
= 330
Hence, the number of visitors purchased guide books is 330 visitors
which is the slope of a line that is perpendicular to the line that passes through the points (29, 24) and (3, 4)?
Answer:
26/20
Step-by-step explanation:
y2-y1 divided by x2-x1
4-24= -20
3-29= -26
-20/-26= m
perpendicular means to switch the numbers and change the sign
a perpendicular slope to -20/-26 is 26/20.

Answer:
∠ GJK = 22°
Step-by-step explanation:
∠ HJI = ∠ JHG ( alternate angles ), then
7x - 16 = 5x + 8 ( subtract 5x from both sides )
2x - 16 = 8 ( add 16 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12 , so
∠ KJI = 7x - 16 = 7(12) - 16 = 84 - 16 = 68°
Then
∠ GJI = 90° ( vertex of a rectangle )
∠ GJK = 90° - 68° = 22°
Write an exponential function in the form y=ab^x that goes through points (0,7) and
(9, 3584).
Answer:y=7(2)^x
Step-by-step explanation:
The exponential function in the form y=ab^x that goes through the given points is f(x) = 7(2)ˣ.
What are Exponential Functions?Exponential functions are functions where the independent variable, x is in the exponent.
The general form of exponential function is,
f(x) = abˣ
The function passes through (0,7) and (9, 3584).
Substituting (0, 7),
7 = a b⁰
7 = a (since b⁰ = 1)
So, a = 7
Function is f(x) = 7bˣ
Now Substituting (9, 3584),
3584 = 7 b⁹
b⁹ = 3584 / 7
b⁹ = 512
b⁹ = 2⁹
b = 2
So the function is f(x) = 7(2)ˣ
Hence the function is f(x) = 7(2)ˣ.

What is the equation of parabola whose vertex is (h, k)?The equation of the parabola whose vertex is (h, k) is
[tex]y = a(x-h)^{2} + k[/tex]
According to the given question.
We have a graph for the function f(x) and g(x).
[tex]f(x) =x^{2}[/tex]..(i)
⇒ the equation of parabola whose vertex is (0, 0)
Since, we know the standard form of the equation of parabola is
[tex]y = a(x-h)^{2} +k[/tex]
Substitute h = 0 and k = 0 in the above equation.
⇒ [tex]y = a(x-0)^{2} +0[/tex]
⇒ [tex]y = ax^{2}[/tex]..(ii) (where, y = f(x))
On comparing the first two equations we get a = 1.
From the graph we can see that g(x) is a equation of parabola, whose vertex is (0, 2).
Therefore, the equation for red graph is given by
[tex]g(x) =a(x-0)^{2} + 2[/tex]
[tex]g(x) = 1x^{2} +2[/tex] (because a = 1)
⇒ [tex]g(x) = x^{2} +2[/tex]
Hence, option c is correct.

Help! Need by 10:30 to turn in and I'm confused!
When Anthony contracted the flu, he needed tissues and cough drops. Each box of tissues cost $1.69 and each bag of cough drops cost $1.19. By the time he was well again, he had gone through a combined 13 boxes of tissues and bags of cough drops, and he had spent $19.47. How many boxes of tissues did he use? How many bags of cough drops?
Answer:
8 boxes of tissues
5 bags of cough drops
Step-by-step explanation:
You need to write a system of equations.
x = number of tissue boxes
y = number of cough drop bags
x (number of tissue boxes) + y (number of cough drop bags) = 13 (total number of tissues and cough drops combined.
So, your first equation is
x + y = 13
Then, you need to write the second equation.
(1.69 [cost of 1 tissue box] * [number of tissue boxes]) + (1.19 [cost of one bag of cough drops] * [number of cough drop bags] = 19.47 [total cost of tissues and cough drops]
That's a lot to read, so here's the equation simplified!
1.69x + 1.19y = 19.47
Now, you have two equations:
x + y = 13
1.69x + 1.19y = 19.47
I would solve with the substitution method.
the first equation can be changed to x = 13 - y by subtracting y from both sides.
Then, your two equations are:
x = 13 - y
1.69x + 1.19y = 19.47
Now, you can plug in that value of x into the second equation!
1.69(13 - y) + 1.19y = 19.47
21.97 - 1.69y + 1.19y = 19.47
subtract 21.97 from both sides
-1.69y + 1.19y = -2.5
Add the y values
-0.5y = -2.5
divide both sides by -0.5
so, y equals 5 bags of cough drops
now that you know what y equals, plug it back into your original equation to find x!
x + y = 13
plug in y
x + 5 = 13
x = 8
so, x = 8 boxes of tissues

what is the slope of the shown below?
f(x) = -3(x - 11)(x + 1)
Answer:
Step-by-step explanation:
Consider the triangle below.
Determine the angle measure for angle A and angle M in order for triangle GAM to be classified as an isosceles triangle.
Given :
▪︎Measure of ∠G = 64°
▪︎△GAM is an isosceles triangle.
We know that :
▪︎The opposite base angles of an isosceles triangle are always equal.
Let the measure of ∠A be x.
Then, the measure of ∠M will also be x.
Which means :
[tex] = \tt64 + x + x = 180[/tex]
[tex] = \tt64 + 2x = 180[/tex]
[tex] = \tt2x = 180 - 64[/tex]
[tex] =\tt 2x = 116[/tex]
[tex] =\tt x = \frac{116}{2} [/tex]
[tex] = \tt \: x = 58[/tex]
Since the sum of all these angles is equivalent to 180°[64+58+58=180], we can conclude that we have found out the correct measure of each of these angles.
▪︎Therefore :Measure of ∠A = 58°
Measure of ∠M = 58°

Given that slope = -1 and a point (3,-1), write an equation in slope-intercept form of the line?
Answer:
Step-by-step explanation:
point-slope equation of the line: y+1 = -(x-3)
rearrange to solve for y:
y+1 = -x+3
y = -x + 2 slope-intercept form
Answer:
y = -x + 2
Step-by-step explanation:
We are given that a line has a slope of -1 and passes through the point (3, -1)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept
As we are already given the slope, we can immediately plug its value into y=mx+b.
Replace m with -1 in y=mx+b.
y = -x + b (there's no need to write -1 in front of x. If -1 is the coefficient in front of a variable, just writing a minus sign in front of the variable is enough).
Now we need to find b.
As the equation passes through the point (3, -1), we can use it to help solve for b.
Substitute 3 as x and -1 as y.
-1 = -3 + b
Add 3 to both sides
2 = b
Substitute 2 as b in the equation so far.
y = -x + 2

What is Pythagora's theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
From the right triangle 1:
Let the hypotenuse be a.
So, a²=1²+1²
⇒a=√2
From the right triangle 2:
Let the hypotenuse be b.
So, b²=(√2)²+1²
⇒b=√3
From the right triangle 3:
Let the hypotenuse be c.
So, c²=(√3)²+1²
⇒b=√4=2
From the right triangle 2:
The hypotenuse=x
So, x²=2²+1²
⇒x=√5
Therefore, the x value for the given partial spiral is √5 units.
