Answer:
<em>Solution; u = 2.5</em>
Step-by-step explanation:
We can neglect the information provided to us, besides that of the equation 9(u – 2) + 1.5u = 8.25, as we are only to find the value of u, any other information is not of need;
9(u – 2) + 1.5u = 8.25 ⇒ apply the distributive property on the expression ( u - 2 ), distributing the 9 to the elements inside,
9u - 18 + 1.5u = 8.25 ⇒ add like elements,
10.5u = 26.25, solve for u,
<em>Solution; u = 2.5</em>
Answer: 25
Step-by-step explanation:
6 x 2 = 12
8 + 4 = 12
therefore, (2 x 6) + (8 + 4) + 1 = 12 + 12 + 1
which gives 25
OK here is it
y=mx+c is the basic equation for a linear graph
If u plot the values above on a graph u'll get a straight line so
m is the slope or if they havent taught u slope is amount of y increases or decreases with respect to x. and C is the intercept or in other words where the graph or the system given above meets the y axis.
the above info is quite unnecessary but important to know
so putting the values into the equation
Youll get the values of m and C so
m=-1/2 and C=11
the relation between x and y is
y=(-1/2)x+11
put the values from the table ull get the right answer
In a quadratic equation of the form (ax^2 + bx + c), the discriminant is equal to (b^2 - 4ac).
So for the first question it would be
4^2 - 4*(6*-2) = 64
Second question (-7)^2 - 4*(9*5) = -131
You can do the rest.
