Answer:

Step-by-step explanation:

Im guessing 2 is also being added. Well basically you add 8 2 and negative 10, which gives you zero, and the value that is left from that is 2d, so its 2d

A machine covers 5/8 square foot in 1/4 hour. what is the unit rate?

Ilia_Sergeevich [38]

we know that

Unit Rate is the ratio of two measurements in which the second term is one

to find the unit rate divide $(5/8)$ by $(1/4)$

$Unit\ rate=\frac{(5/8)}{(1/4)}= \frac{5}{8}*4= \frac{2.5}{1} =2.5 \frac{ft^{2}}{hour}$

therefore

the answer is

The unit rate is $2.5 \frac{ft^{2}}{hour}$

PLEASE HELP!! Will give brainliest if you give explanation!

MArishka [77]

The equation in slope-intercept is y=0.625x+7.

y = mx + b

where:
m is the slope of the line
b is the y-intercept of the line

The slope m of the line through any two points (x1, y1) and (x2, y2) is given by:

The y-intercept b of the line is the value of y at the point where the line crosses the y axis. Since for point (x1, y1) we have y1 = mx1 + b, the y-intercept b can be calculated by:

b = y1 - mx1. hope that helped
