The ratio of two numbers is 7:2. If the greater number is 28, find the smaller one.
Answer:
Answer:
8
Step-by-step explanation:
7 : 2
We know the larger number is 28
28 : x
We multiply 7 * 4 = 28, so multiply the first ratio by 4
7*4 : 2*4
28 : 8
The second number is 8

At what coordinate point with the graph of y = 3x - 8 intersect that of its inverse?
Answer:
Point of Intersection: (-4, -4)
Step-by-step explanation:
Given the linear equation, y = 3x + 8:
We must determine its inverse, which will enable us to find the point of intersection between the given equation and its inverse.
Start by switching x and y in the given linear equation:
y = 3x + 8
x = 3y + 8
Next, subtract 8 from both sides:
x - 8 = 3y + 8 - 8
x - 8 = 3y
Multiply both sides with ⅓ to isolate y:
⅓ (x - 8) = (3y) ⅓
[tex]\displaytext\mathsf{\frac{1}{3}x\:-\frac{8}{3}\:=\:y}[/tex]
Replace y with [tex]\large{\textit{f}\:^{-1}(\textit{x}\:)}[/tex]:
[tex]\displaytext\mathsf{\textit{f}\:^{-1}(\textit{x}\:)\:=\frac{1}{3}x\:-\frac{8}{3}}[/tex] ⇒ This is the inverse function of y = 3x + 8.
Graph both equations:Next, we must graph both equations.
Plot the y-intercept, (0, 8), and use the slope of the given linear equation, m = 3, to plot other points on the graph.
Similarly, to graph the inverse function, take the y-intercept, [tex]\displaytext\sf{(0,\:-\frac{8}{3})}[/tex], and use the slope, m = ⅓, to plot other points on the graph.
Attached is the graph of the linear equation, y = 3x + 8, and its inverse, [tex]\displaytext\mathsf{\textit{f}\:^{-1}(\textit{x}\:)\:=\frac{1}{3}x\:-\frac{8}{3}}[/tex] , where it shows that the point of intersection occurs at point, (-4, -4).

What are the domain, range, and asymptote of h(x) = (1.4)x + 5?domain: {x | x is a real number}; range: {y | y > 5}; asymptote: y = 5domain: {x | x > 5}; range: {y | y is a real number}; asymptote: y = 5domain: {x | x > –5}; range: {y | y is a real number}; asymptote: y = –5domain: {x | x is a real number}; range: {y | y > –5}; asymptote: y = –5
Answer:
A.Domain:{x\x is a real number }
Range:{y\y>5}
Asymptote :y=5
Step-by-step explanation:
We are given that a function
We have to find the domain, range and asymptote of h(x).
It is exponential function therefore, it is defined for all values of x.
Hence, domain of h(x)={x| x is a real number}
Substitute x=0 then we get
(a^0=1)
Hence, range of h(x)={y|y>5}
For exponential function,
Horizontal asymptote: when
Apply limit
Hence, the horizontal asymptote y=5.

A coat was originally priced at $175. It went on sale for $113.75. What was the percent that the coat was discounted
Answer:
35% (decrease)
Step-by-step explanation:
V2-V1/V1 x 100
= 113.75-175/175 x 100
= -61.25/175 x 100
= -0.35 x 100

❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
[tex] {x}^{2} = 100[/tex]
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Answer:
your equation is this... x2 - 100
since you have no x term to the first power you can write 0x... like this
x2 + 0x - 100
Now, what numbers will add to 0 and multiply to -100
The numbers 10 and -10 will
10 + -10 = 0
10 * -10 = -100
therefore
(x - 10)(x + 10) is the way you factor it

An arithmetic sequence is given below.

write an explicit formula for the nth term an
an = ???
-please help
________
[tex] \: [/tex]
an = 8 + (n - 1) × 4
an = 8 + 4n - 4
an = 4n + 4
Answer:
[tex]a_{n}[/tex] = 4n + 4
Step-by-step explanation:
The nth term (explicit formula) of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = a₂ - a₁ = 12 - 8 = 4 , then
[tex]a_{n}[/tex] = 8 +4(n - 1) = 8 + 4n - 4 = 4n + 4

solve pls brainliest
Answer:
64%
Step-by-step explanation:
Step 1: Divide 16 by 25
-> [tex]\frac{16}{25}[/tex] -> [tex]0.64[/tex]Step 2: Multiply quotient by 100.
[tex]0.64 * 100[/tex] [tex]6.4 * 10[/tex] [tex]64[/tex] 64%Therefore, 16/25 as a percentage is 64%.
Answer:
Well you can make a proportion
Percentage means ”Out of a hundred”
So you can make a proportion with any fraction Equal to x/100 since
X is the unknown perctange.
in this case it’s 16/25
16/25 = x/100
So cross multiply To solve for X
1600= 25x
x= 64
So 64 Percent
In this case you can use benchmarks. If you do it more or long enough, you’d memorize them.
In this case 25 is a bench mark of 1/4 or 25. 25 goes into 100 4 times so you can multiply 16 by 4 to get your percentage since if you do multiply 4, you have to do it to both the numerator and the Denominator.
so 16/25
16*4= 64
25*4=100
64/100 or 64 percent.
Common benchmarks for percentages
5, 10, 20, 25, 50
5 is always multiply by 20
10 is always multiply by 10
20 is always multiplied by 5
25 is always multiplied by 4
50 is always multiplied by 2
