Answer:
t = w/(r1 + r2)
Step-by-step explanation:
ngl, I guessed on edgenuity and it ended up being the right answer lol.
Just remember to isolate the variable and work your way through different ideas to get the right answer. There are two methods to get the right answer, but I'll use the division method (theres also the distributive property but its more work).
start--> w=t(r1+r2)
divide both sides by (r1 +r2)
answer: w/(r1 + r2) = t
The product of a negative number and a positive number is always negative.
Here's something funny my math teacher once told us to help us remember.
Good thing happening to a Good person = Good
positive x positive = positive
Bad thing happening to a Good person = Bad
negative x positive = negative
Good thing happening to a Bad person = Bad
positive x negative = negative
Bad thing happening to a Bad person = Good
negative x negative = positive
Given:
The table of values.
To find:
The slope and y-intercept for this line.
Solution:
From the given table, we have three (-4,6), (0,3), (4,0).
We need to find the slope and y-intercept for this line.
Consider any two points from the given points.
Consider the line passes through the points (0,3) and (4,0). So, the slope of the line is:
The line passes through the point (0,3). Here the x-coordinate is 0. So, the y-intercept is 3.
Therefore, the slope of the line is and the y-intercept of the line is 3.
(22,12) m=4
y=mx+b
12=4*22+b
12=88+b
subtract 88 from each side
b=-76
y = 4x-76
subtract 4x from each side
-4x+7 = -76
Choice A
