37 points! The square root of 83 can be plotted on the number line below.

Nikitich [7]

Answer:

9.1 is the nearest tenth

9.11 to the nearest hundredth

just slightly to the right of 9.1

Step-by-step explanation:

sqrt(83)

sqrt(81) = 9

So we know that it is slightly greater than 9

9.1*9.1 =81.81

9.2*9.2=84.64

9.1 is closer

9.11 * 9.11 =82.9921

9.12 * 9.12 =83.1744

9.11 is closer

Assuming you meant fractions, to divide them, you must multiply the reciprocal of that fraction. You'll then have:

4/5x15/8

Reduce the numbers of the greatest common factor which is 5:

4x3/8

Reduce the numbers of the greatest common factor which is now 4:

Simplify completely x^2+4x-5/5x^2-8x+3

arlik [135]

Answer:

$\boxed{\bold{\frac{x+5}{5x-3}}}$

Explanation:

[ Step One ] Factor $\bold{x^2+4x-5}$

$\bold{x\left(x-1\right)+5\left(x-1\right)}$

[ Step Two ] Rewrite Equation

$\bold{\frac{\left(x-1\right)\left(x+5\right)}{5x^2-8x+3}}$

[ Step Three ] Factor $\bold{5x^2-8x+3}$

$\bold{\left(x-1\right)\left(x+5\right)}$

[ Step Four ] Rewrite Equation

$\bold{\frac{\left(x-1\right)\left(x+5\right)}{\left(5x-3\right)\left(x-1\right)}}$

[ Step Five ] Cancel Out Common Factor $\bold{x-1}$

$\bold{\frac{x+5}{5x-3}}$

$\boxed{\bold{Mordancy}}$

What is the equation for f(x)

Paraphin [41]

F(x) = -5/6x - 3

You can get this by identifying the y-intercept and then using the formula for slope given any two points on the graph.
