Answer:
y=2x+7
Step-by-step explanation:
you would substitute so x=-2 and y=3
All lines parralel always have the same x so
y=2x-c (c means crossing point of y)
then substitute
3=(2x-2)-c
3=-4-c
c= +7
so just put in the equation and the answer is:
y=2x+7

Answer:
2.995 ou 35.940 (?)
Step-by-step explanation:
Não me lembro exatamente como fazer isso, vou mostrar duas maneiras diferentes de resolver isso.
Use a fórmula l = P * r * t
| = Juros
P = Principal
r = taxa
t = tempo
Para resolver isso, você terá que ... O principal é 29.950, a taxa é 5%, mas se tornará um decimal que é 0,05, e o tempo é 2 Coloque-o na forma de fórmula 29.950 * 0,05 * 2 = 2.995 em interesse
Ou .. Você usará a mesma fórmula, mas desta vez multiplique 0,05 por 12, pois há 12 meses em um ano que é 0,6, então ... 29.950 * 0,6 * 2 = 35.940 de juros
Espero que funcione!
Answer:
20 is 80% of 25
Step-by-step explanation:
We assume, that the number 25 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 25, so we can write it down as 100%=25.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=25
2) x%=20
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=25/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 20 is what percent of 25
100%/x%=25/20
(100/x)*x=(25/20)*x - we multiply both sides of the equation by x
100=1.25*x - we divide both sides of the equation by (1.25) to get x
100/1.25=x
80=x
x=80
