Answer:

The slope is -10, and the y-intercept is 1.

Step-by-step explanation:

Assuming that the equation is y = -10x+1, the easiest way to identify slope and the y-intercept is by knowing the equation for slope-intercept (y = mx+b)

Equation for slope-intercept (y = mx+b) explained:

The equation is y = mx+b, let's break it down.

y = The line

m = The slope

b = The y-intercept

Now that we know the equation and broke it down you can identify them in your equation

Slope (m)= -10

y-intercept = 1

Conclusion: The slope is -10, and the y-intercept is 1.

Evaluate 8-2.<br>A. -16<br>B. -64<br>C. -1/64<br>D. 1/64<br>

I'm assuming you meant to write 8^(-2) or $8^{-2}$ where the -2 is the exponent over the 8.

If my assumption is correct, then we use the rule $a^{-b} = \frac{1}{a^b}$

So,

$a^{-b} = \frac{1}{a^b}\\\\8^{-2} = \frac{1}{8^2}\\\\8^{-2} = \frac{1}{64}$

<h3>Answer: Choice D. 1/64</h3>

Find the circumference of the circles below. Round your answer to the nearest whole number. Use 3.14 for Pi.

Lisa [10]

Answer:

$\huge\boxed{1.\ C\approx38cm;\ 2.\ C\approx57ft;\ 3.\ C\approx50in.}$

Step-by-step explanation:

The formula of a circumference of a circle:

$C=2\pi r\\\\r-\text{radius}$

$1.\\r=6cm\\\\C=2\pi\cdot6=12\pi\\\\\pi\approx3.14\\\\C\approx12\cdot3.14=37.68\approx38(cm)\\\\2.\\r=9ft\\\\C=2\pi\cdot9=18\pi\\\\\pi\approx3.14\\\\C\approx18\cdot3.14=56.52\approx57(ft)\\\\3.\\2r=16in.\to r=8in.\\\\C=2\pi\cdot8=16\pi\\\\\pi\approx3.14\\\\C\approx16\cdot3.14=50.24\approx50(in.)$

Mr. Jackson rented a storage unit in the shape of a rectangular prism. The volume of the unit is 230 cubic yards. The storage un

attashe74 [19]

Answer:

4 yards

Step-by-step explanation:

the formula for finding the volume of a shape is volume= to length times with times how tall it is. In this case we do not have the hight so we make a formula. 5 and 3/4 times 10 times hight = to 230. If you do the math you get 4 yards as the answer.
