Answer:
b= 322.8
Step-by-step explanation:
10.50a + 3.75b = 2071.50
10.50 (82) + 3.75b = 2071.50
861 + 3.75b = 2071.50
-861 -861
3.75b = 1210.5
/3.75 /3.75
b = 322.8
Answer:
table a
Step-by-step explanation:
To be a function, every x has to have exactly one y. In table b the x value 5 has an output of 2 and 6 and therefore, since it has more than one y it is not a function. In table D the x value 6 has a y output of 7 and 2. Therefore it is not a function. In table A every x has exactly one y.
Any rhombus has the same length for all for sides, so:
x + 14 = 3x +4
So, we get x = 5
Now, we can write
x + 14 = 8y
Since x = 5,
19 = 8y
so y = 19/8 = 2.375
<span>You can take any one of the equations and substitute the value of x or y in. The length is 19</span>
Answer:
The coefficient of x² in the expression is 2
x/3(6x-1/2) = 6x²/3 - x/6
= 2x² - x/6
