Answer:
Step-by-step explanation:
The skope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have the points (2, -1) and (5, -3). Substitute:
We have the equation:
Put the coordinates of the point (2 , -1) to the equation:
<em>add 4/3 to both sides</em>
Finally we have:
In order to get who was right we need to solve the expression:
2a^2b(-2ab^3)^-2
The above can be written as fraction to get:
(2a^2b)/(-2ab^3)^2
=(2a^2b)/(4a^2b^6)
=1/2(a^(2-2)b^(1-6))
=1/2a^0b^-5
=1/2b^(-5)
This implies that neither of the was right
X is t shirt is $8
Y is sweatshirt $11
2x+2y=38
3x+1y=35
We will be using the elimination process so you want even them out same value
2x+2y=38
-6x-2y=-70 ( want get rid of the y-value by increasing to other by when both add or subtract it will equal 0)
-4x=-32
Divide both -4
X=8 So 8 dollars a t-shirt so now will fill x with 8
2(8)+2y=38
16+2y=38
-16
2y=22
Divid by 2
Y = 11 so a sweatshirt is 11 dollars
You can check by fill each by the variable
Answer:
99
Step-by-step explanation:
102F down by 3F would be 99 and it says then. Then would be the 'two hrs later'.
