Answer:

a cube that is 1 yard long, 1 yard wide, and 1 yard high

Step-by-step explanation:

1\times1\times1

<u>Please note that the units for each side MUST be the same (or if they're different, then the lengths have to be equivalent). </u>

<u />

Looking at the answer choices, we can see that the last answer choice is a 1 yd by 1 yd by 1 yd cube, therefore it is a unit cube.

Answer:

Rewrite the function as an equation.

y

=

5

x

−

Use the slope-intercept form to find the slope and y-intercept.

Tap for fewer steps...

The slope-intercept form is  

y

=

m

x

+

b

, where  

m

is the slope and  

b

is the y-intercept.

y

=

m

x

+

b

Find the values of  

m

and  

b

using the form  

y

=

m

x

+

b

.

m

=

The slope of the line is the value of  

m

, and the y-intercept is the value of  

b

.

Slope:

Any line can be graphed using two points. Select two  

x

values, and plug them into the equation to find the corresponding  

y

values.

Helpppp!! i need work and the answer!!
xxTIMURxx [149]

500 - 125 = 375

72.50 × 6 = 435

435 - 375 = 60.

Divide the part (60) by the whole (500) then multiply by 100 to get the percent.

60 / 500 = .12

.12 × 100 = 12%

The correct answer is B
