<h3>
Answer: choice D. (5, 28)</h3>
====================================================
Explanation:
The idea is to plug in each pair of coordinates and see if you get a true equation. Choice A does not work because
y = 6x-2
20 = 6(6)-2 ... plugged in x = 6 and y = 20
20 = 36-2
20 = 34
we have a false equation. So this shows choice A does not work.
--------
However, choice D does work since...
y = 6x-2
28 = 6(5)-2 .... plug in (x,y) = (5,28)
28 = 30-2
28 = 28
Put another way, if we plugged x = 5 into the equation, then we'd get y = 28. Therefore, showing (5,28) is a point on the line y = 6x-2.
Answer:
18/17
Step-by-step explanation:
the negative reciprocal of -289/324 is 324/289. When it is multiplied by 17/18 you get 18/17 as the answer.
Answer:
Step-by-step explanation:
We translate Grayson's charges through the following mathematical expression : 35 h + 35 where h is the number of hours while that of Ian is 45h + 15. The number of hours where the charges are equal is 35h + 35 = 45h + 15; h = 2 hrs. Hence the number of hours minimum must be above 2 hours.
Hey there! I'm happy to help!
A step function is a function that looks like stairs when you graph it. Normally the end of one line will be graphed as an open circle (less or greater than, not equal to) while the other end would be a closed circle. This allows for a new line of the function to start directly above it without it not being a function (an input cannot have two outputs)
The function f(x)=4 is just a horizontal line as it has a slope of 0 (there is no x on the right side of the equation), so this doesn't resemble a step function.
Have a wonderful day and keep learning! :D
(b-7)m=r
Use the distributive property to multiply b-7 by m.
bm-7m=r
Add 7m to both sides.
bm=r+7m
The equation is in standard form.
mb=7m+r
Divide both sides by m.
mb/m = 7m+r/m
Dividing by m undoes the multiplication by m.
b= 7m+r/m
Divide r+7m by m.
b= r/m+7
