Answer:

x > 8

Step-by-step explanation:

$\frac{3}{4}$ x + 5 > 11

$\frac{3}{4}$ x > 6 --- subtract 5 from both sides

x > 8 --- divide both sides by $\frac{3}{4}$

Simplify the following rational expression without using a calculator: (12².6³.5²)/(18².15).

prohojiy [21]

Answer:

160

Step-by-step explanation:

$\dfrac{12^2\cdot 6^3\cdot 5^2}{18^2\cdot 15}=\dfrac{(2^2\cdot 3)^2\cdot (2\cdot 3)^3\cdot 5^2}{(2\cdot 3^2)^2\cdot (3\cdot 5)}\\\\=\dfrac{(2^4)(3^2)(2^3)(3^3)(5^2)}{(2^2)(3^4)(3)(5)}=(2^{4+3-2})(3^{2+3-4-1})(5^{2-1})=32\cdot 5\\\\=\bf{160}$

Answer:

$2,295$ $dollars$

Step-by-step explanation:

This is our equation that I could find within this question.

$2000(1+.035)^4$

$==> 2000(1.035)^4$

$==> 2000 * 1.1475$

$==> 2,295$

Can someone please help me with this? I'd greatly appreciate it! Serious answers only please!

First find the slope:
The slopes of perpendicular lines must multiply to -1.
-9m = -1 ----> m = 1/9

Next, use point-slope form:
y - y1 = m(x-x1) , where given point (0,5) is (x1,y1)
y - 5 = (1/9)(x - 0)

Finally, solve for y to put it in slope-intercept form:
y = (1/9)x + 5

What is an equation of the line that passes through the points (4,-2) and (8,3)?

Maslowich

Answer:

$y-4=\frac{5}{4} (x+2)$

Step-by-step explanation:

First you can find the slope of the line that would pass through those two points using the formula:

m = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

m = $\frac{3-(-2)}{8-4}$

m=5/4

Now you can just plug the slope and one of the points into point-slope form for an equation of the line that will pass through both points. You can choose either point here: I'll just use the first one.

So,

$y-4=\frac{5}{4} (x+2)$

(don't leave out the parentheses!)
