Write an equation of the line passing through each of the following pairs of points.

slavikrds [6]

Answer:

$y=\frac{1}{3}+\frac{13}{3}$

Step-by-step explanation:

We want to write the equation of a line that passes through (5, 6) and (-1, 4).

First, let's find our slope. We can use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Let's let (5, 6) be (x₁, y₁) and let's let (-1, 4) be (x₂, y₂). So, our slope is:

$m=\frac{4-6}{-1-5}$

Subtract:

$m=-2/-6$

Reduce:

$m=1/3$

So, our slope is 1/3.

Now, we can use the point-slope form, which is:

$y-y_1=m(x-x_1)$

For consistency, let's let (5, 6) be (x₁, y₁). We will also substitute 1/3 for m. So:

$y-6=\frac{1}{3}(x-5)$

Distribute:

$y-6=\frac{1}{3}x-\frac{5}{3}$

Add 6 to both sides:

$y=\frac{1}{3}x-\frac{5}{3}+\frac{18}{3}$

Add:

$y=\frac{1}{3}+\frac{13}{3}$

And we're done!

Solve this equation 3.5(2.5 + x) = 14

Mashcka [7]

Answer: so first you want to do 3.5 x the 2.5 and you get 8.75, then do 3.5 x X and you get 3.5x. now the equation is 8.75 +3.5x=14. take 8.75 nnd subtract it from itself and 14 then you are left with 3.5x=5.25. divide 5.25 by 3.5x and you get 1.5. so the answer is x=1.5

7. If (0.2)x = 2 and log 2 = 0.3010, then the value of x to the nearest tenth is?

prisoha [69]

(0.2)x = 2.

Taking log on both sides

log (0.2)x = log 2.

x log (0.2) = 0.3010, [since log 2 = 0.3010].

x log (2/10) = 0.3010.

x [log 2 - log 10] = 0.3010.

x [log 2 - 1] = 0.3010,[since log 10=1].

x[-0.699] = 0.3010.

x= 0.3010/-0.699.

x= = -0.4306….

x= = -0.4.
