Answer:

x = 5

Step-by-step explanation:

In a parallelogram, the diagonals bisect each other.

Therefore,

4x - 5 = 3x

4x = 3x + 5

4x - 3x = 5

x = 5

Answer: 6.3093

Step-by-step explanation:

$3^{\frac{x}{5}} = 4$

$ln3^{\frac{x}{5}} = ln4$

$\frac{x}{5} ln3 = ln4$

xln3 = 5ln4

$x = \frac{5ln4}{ln3}$

x = 6.3093

Answer: 5, 3, $\frac{1}{5}$ , D

Step-by-step explanation:

a) x ≤ 0 so, f(-5) = | -5 | = 5

x ≤ 0 so, f(-3) = | -3 | = 3

x > 0 so, f(5) = $\frac{1}{5}$

b) graph D

Answer: $\frac{\pi}{12}$

Step-by-step explanation:

$\frac{25\pi}{12} - \frac{2\pi}{}$

= $\frac{25\pi}{12} - \frac{24\pi}{12}$

= $\frac{\pi}{12}$

Write an equation in slope intercept form for the line that passes through (-1, -2) and (3, 4)

LenaWriter [7]

Answer:

The slope-intercept form of the line equation is:

$y=\:\frac{3}{2}x\:-\frac{1}{2}$

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

m is the slope

b is the y-intercept

Given the points

(-1, -2)

(3, 4)

Determining the slope between (-1, -2) and (3, 4)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-1,\:-2\right),\:\left(x_2,\:y_2\right)=\left(3,\:4\right)$

$m=\frac{4-\left(-2\right)}{3-\left(-1\right)}$

$m=\frac{3}{2}$

Thus, the slope of the line is:

m = 3/2

substituting m = 3/2 and the point (3, 4) in the slope-intercept form of the line equation

y = mx+b

$4=\frac{3}{2}\left(3\right)+b$

switch sides

$\frac{3}{2}\left(3\right)+b=4$

$\frac{9}{2}+b=4$

subtract 9/2 from both sides

$\frac{9}{2}+b-\frac{9}{2}=4-\frac{9}{2}$

$b=-\frac{1}{2}$

now substituting m = 3/2 and b = -1/2 in the slope-intercept form of the line equation

$y = mx+b$

$y=\:\frac{3}{2}x\:+\:\left(-\frac{1}{2}\right)$

$y=\:\frac{3}{2}x\:-\frac{1}{2}$

Therefore, the slope-intercept form of the line equation is:

$y=\:\frac{3}{2}x\:-\frac{1}{2}$

Find f(-2) for the function f(x)=x^2-6

lorasvet [3.4K]

You would subitute -2 for x in the equation
f(-2)=x^2-6
PEMDAS so exonents
-2^2-6
negative times a negative= positive
4-6
f(-2)=-2

f(x) means that you subsitute x for x in the equation exg
f(1)=x+2 means f(1)=1+2
f(4)=x+2 means f(4)=4+2
