What is this equation in point-slope form?

deff fn [24]

Answer:

y - 2 = $\frac{1}{2}$ (x + 8)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = $\frac{1}{2}$ and (a, b) = (- 8, 2), hence

y - 2 = $\frac{1}{2}$ (x + 8) ← in point- slope form

Solve using quadratic formula pls show work

Temka [501]

Answer:

$x=\frac{3}{8},\:x=0$

Step-by-step explanation:

$x_{1,\:2}=\frac{-\left(-3\right)\pm \sqrt{\left(-3\right)^2-4\cdot \:8\cdot \:0}}{2\cdot \:8}$

$\sqrt{\left(-3\right)^2-4\cdot \:8\cdot \:0}$

$=\sqrt{3^2-4\cdot \:8\cdot \:0}$

$\sqrt{3^2}$

$x_{1,\:2}=\frac{-\left(-3\right)\pm \:3}{2\cdot \:8}$

Separate the solutions:

$x_1=\frac{-\left(-3\right)+3}{2\cdot \:8},\:x_2=\frac{-\left(-3\right)-3}{2\cdot \:8}$

$x=\frac{3}{8},\:x=0$

A population of caribou in a forest grows at a rate of 5% every year. If there are currently 248 caribou, which function represe

ANEK [815]

Answer: I think that the answer is C because 5% is 5 out of 100 and 5 out of 100 as a decimal is 0.05 and you are trying to find how much the population will have increased so you have to multiply 248 by 5% or you have to multiply 248 by 0.05
