Segundo o Instituto Nacional de Pesquisas Espaciais (Inpe), de janeiro a setembro de 2019, foram registrados 4.660 focos de incêndio, em 2020 foram registrados 14.489 focos. Qual é a porcentagem de aumento de focos de incêndio em 2020 em comparação com os focos registrados em 2019?

A fórmula de aumento percentual é fornecida como

Aumentar / tamanho inicial × 100

Aumento = 14489 focos de incêndio - 4660 focos de incêndio

= 9829 focos de incêndio

Aumento percentual = 9829/4660 × 100

= 210.92274678 %

Write an equation off the line that passes through the point -4 -3 and is parallel to 4 y- X=- 16
ycow [4]
Parallel lines on a graph need to have the same slope. So if you put 4y-x=-16 is slope-int form, you get y=1/4x-4. Now, you have to make another equation like this. So since you know that the slope has to be 1/4, the start of the equation for a line that passes (-4,-3) is y=1/4x. Now, When you plug in -4 is in the x, you get 1/4(-4)=-3. However, -1=-3 is not true. So, what do you add or subtract to -1 to get -3? You get -2, which is the y-intercept in the slope-int form, mx+b. So for your final equation, you get y=1/4x-2
