Find the solution set for 8x^-9x=-1
Answer:
[tex]\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}[/tex]
[tex]x=\frac{1}{8},\:x=1[/tex]
Step-by-step explanation:
Given the equation
[tex]8x^2-9x=-1\:\:[/tex]
Add 1 to both sides
[tex]8x^2-9x+1=-1+1[/tex]
[tex]8x^2-9x+1=0[/tex]
as
[tex]\left(8x-1\right)\left(x-1\right)=8x^2-9x+1[/tex]
so the equation becomes
[tex]\left(8x-1\right)\left(x-1\right)=0[/tex]
Using the zero factor principle:
[tex]\:If}\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]
so
[tex]8x-1=0\quad \mathrm{or}\quad \:x-1=0[/tex]
solving
[tex]8x-1=0[/tex]
[tex]8x=1[/tex]
[tex]\frac{8x}{8}=\frac{1}{8}[/tex]
[tex]x=\frac{1}{8}[/tex]
also solving
[tex]x-1=0[/tex]
[tex]x=1[/tex]
[tex]\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}[/tex]
[tex]x=\frac{1}{8},\:x=1[/tex]

(M1219Q3SP) Um aplicativo de transporte de passageiros cobra uma taxa de R$ 0,75 por viagem, chamada de "Custo Fixo". Além dos R$0,75, a tarifa do aplicativo tem preço base inicial de R$2 e cobra R$1,40 por quilômetro rodado e R$ 0,26 por minuto de viagem. Considerando a distância percorrida em quilômetros igual a “q” e o tempo de viagem em minutos igual “t”, qual a função que representa o valor a ser cobrado por uma viagem usando esse aplicativo de transporte de passageiros é:
Somando todas as despesas, a função é dada por:
[tex]C(q,t) = 2.75 + 1.4q + 0.26t[/tex]
----------------------
Custo fixo de R$ 0,75:
Isto implica que:
[tex]C = 0.75[/tex]
As outras despesas são:
Preço base de R$ 2 mais 1,40 por cada quilômetro q.R$ 0,26 por cada minuto t de viagem.Então, a função é:
[tex]C(q,t) = 0.75 + 2 + 1.4q + 0.26t[/tex]
[tex]C(q,t) = 2.75 + 1.4q + 0.26t[/tex]

A busload of campers stopped at a dairy stand for ice cream. They ordered 74 cones, some soft serve at 1.50 each and the rest hard pack at 1.25 each. If the total bill was 100, how many of each type of cone were ordered?
Answer:
40 of the hard pack, 33 of the soft serve
Step-by-step explanation:
x1.25+b1.50=100
100÷2=50
40×1.25=50
33×1.50=49.5
self check
50+49.5=100
(40) 1.25 + (33) 1.50 = 99.5, cant go any higher than that because the price was 100. 50 cents isnt going to buy the 1.25 hard pack or the 1.50 soft shell. so the answer would be 40 of the hard pack and 33 of the soft serve

Answer: x = 84°.
Step-by-step explanation: The sum of interior angles of a quadrilateral is equal to 360°. We are given three of the interior angles and asked to find the remaining angle. To do this, we can add the three given angles and subtract the sum from 360°. 53° + 125° + 98° = 276°. 360° - 276° = 84°. Thus, x = 84°.

If f(x)=3x^2+1 and g(x)=1-x, what is the value of (f-g)(2)?
The answer should be 14.
You just have to substitute x with the given number and finish the equation.
Answer:
[tex](f-g)(2)=28[/tex]
Step-by-step explanation:
Given:
[tex]f(x)=3x^2+1[/tex]
[tex]g(x)= 1-x[/tex]
To find the equivalent expression of [tex](f-g)(2)[/tex].
[tex](f-g)(2) = f(2) - g(2)[/tex]
Find g(x)
[tex]g(x)=1-x[/tex]
Sub x for 2
[tex]g(2)=1-2[/tex]
[tex]g(2)=-1[/tex]
Find f(x)
[tex]f(x)=3x^2+1[/tex]
Sub x for 2
[tex]f(2)=3(2)^2+1[/tex]
[tex]f(2)=12+1[/tex]
[tex]f(2)=12+1[/tex]
[tex]f(2)=13[/tex]
Solve for the giving value

The age of the older of two boys is twice that of the younger; 5 years ago it
was three times that of the younger. Find the age of each. pls include steps will mark brainiest
Answer: The older boy is now 20, the younger boy is now 10.
Step-by-step explanation: Explanation:
Let the age of the older boy now be y
let the age of the younger boy now be x
y = 2x
y-5 = 3(x-5)
simplifying
y = 3x - 10
substituting for y in equation 1
2x = 3x-10
simplifying
x = 10
substituting into 1
y = 20
