Answer: 18.7

Step-by-step explanation:

Find the lengths of AB, BC, and CA

AB = $\sqrt{(4-(-1))^{2} + (-1-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

BC = $\sqrt{(0-(-1))^{2} + (-3-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

CA = $\sqrt{(0-4)^{2} + (-3-(-1))^{2} }$ = 2 $\sqrt{5}$ ≈ 4.5

7.1 + 7.1 + 4.5 = 18.7

Solve for X. Please!!

pychu [463]

Answer:

x = 37.5

Step-by-step explanation:

By Basic Proportionality Theorem:

$\frac{x}{20} = \frac{46 - 16}{16} \\ \\ \frac{x}{20} = \frac{30}{16} \\ \\ x = \frac{20 \times 30}{16} \\ \\ x = \frac{600}{16} \\ \\ x = 37.5$

A line passes through the point (2, 10) and has a y-intercept of 4. What is the equation of the line?

KatRina [158]

Answer:

$y=3x+4$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is equal to 0)

1) Determine the slope (m)

$m=\frac{y_2-y_1}{x_2-x_1}$ where two points that the line passes through are $(x_1,y_1)$ and $(x_2,y_2)$

We're given the point (2,10) and the y-intercept of 4. Recall that the y-intercept occurs when x is equal to 0. This means that the y-intercept occurs at (0,4), giving us our second point.

Plug these points into the equation

$=\frac{10-4}{2-0}\\=\frac{6}{2}\\=3$

Therefore, the slope of the line is 3. Plug this into $y=mx+b$

$y=3x+b$

2) Determine the y-intercept (b)

The y-intercept is given; it is 4. Plug this back into $y=3x+b$

$y=3x+4$

I hope this helps!
