Answer:
-4x=4
Step-by-step explanation:
-4x+7=11 subtract 7 add to the 11 answer-4x=4
1/2, try taking out the biggest number out of both of the numbers, in this case five can be taken out of both the numbers, leaving you with 1/2 :)
First find slope.
slope=change in y/change in x (y2-y1/x2-x1)
slope=4-3/-2-(-4)=1/2
Now we need to find the x intercept.
y=mx+b
3=1/2(-4)+b
b=5
So the equation is y=1/2x+5.
Answer:
Below in bold.
Step-by-step explanation:
The general form of a linear function can be written as:
n(p) = kp + C where k and C are constants.
So substituting the given data:
8000 = 3k + C
5200 = 5k + C Subtract
2800 = -2k
k = -1400
and C = 8000 - 3(-1400) = 12200
a. So the equations is:
n(p) = -1400p + 12200
b.
For a charge p of $6.50;
n(p) = -1400*6.5 + 12200
= 3100 balls.
Answer:
252 cm^2
Step-by-step explanation:
Let x be the length
and
y be the width of rectangle
Then, the area will be:
If the length and width are changes by a scale factor 1.5.
Then the area will be:
We already know that xy=112
So the new area will be:
