Are there any answer choices
About Slope Intercept Form:
- y = mx + b
- m is the slope
- b represents the y-intercept
For the graphing one, since the slope is positive, you have to go up 5 and right 2 because the slope equals <u>rise</u>
run.
5 represents rise & 2 represents run. Then -4 is the starting point, the y-intercept.
Hope this info helps!! :)
Answer:
see the explanation
Step-by-step explanation:
Let
x ----> number of tennis balls
y ----> number of tennis rackets
we know that
To find out the ratio of tennis balls to tennis rackets, divide the number of tennis ball by the number of tennis rackets
In this problem we have
see the model in the attached figure N 1
so
This is the equation of a linear direct variation
The relationship between the variables x and y is proportional
see the model in the attached figure N 2
112.5 minutes
Since there are 60 minutes in 1 hour so multiply that by 3 and you get 180 minutes
180➗8=22.5
22.5✖️5= 112.5 minutes
Hope this helps! :3
Answer:
10 and 42
Step-by-step explanation:
The difficulty with word problems is translating them into math.
Let's do that
---------------------
The sum of a number and two times a smaller number is 62.
let's call the bigger number b, and the smaller number s
b + 2s = 62
Three times the bigger number exceeds the smaller number by 116
3b = s + 116
-----------------------
Now manipulate one of the equations to isolate the variable
3b = s + 116
Subtract 116 from both sides
3b - 116 = s
substitute for s = 3b - 116 in
b + 2s = 62
b + 2(3b - 116) = 62
Distribute
b + 6b - 232 = 62
combine like terms
7b = 294
Divide both sides by 7
b = 42
to find s plug in b = 42 into
b + 2s = 62
42 + 2s = 62
subtract 42 from both side
2s = 20
divide both sides by 2
s = 10
