Answer:
B. $264.00
Step-by-step explanation:
==>The image that shows the pattern of the arrangement of tiles consists of:
2 large tiles = $0.96*2 = $1.92
8 small tiles = $0.26*8 = $2.08
This implies that $4 would need to be spent to cover 1ft²
Therefore, to cover an area of 22ft by 3ft, it would cost Fred the following below:
Area to be covered = 22×3 = 66ft²
$4 --> 1ft²
x$ ---> 66ft²
= (66 × 4)/1
= $264.00
The third one is the product
2×-1 =-2
2×0=0
ans(-2 0)
X=4. If k is the midpoint then JK is equal to KL. Since JK is 7 then KL is also 7 meaning JK is 14. JK is represented by the expression 4x-2 so you just set that expression equal to 14 and solve for x. Hope this helped!
First set up a linear equation and using the x and y values in the table see if it solves.
It doesn't solve so we know it isn't linear. ( I won't show all those steps because they aren't needed.)
Using the quadratic formula y = ax^2 +bx +c
Build a set of 3 equations from the table:
C is the Y intercept ( when X is 0), this is shown in the table as 6
Now we have y = ax^2 + bx + 6
-2.4 =4a-2b +6
1.4 = a-b +6
Rewrite the equations
a=b/2 -2.1
1.4 = b/2-2.1 +6
b = 5
a = 5/2 -2.1 = 0.4
replace the letters to get y = 0.4x^2 + 5x +6
