Answer:
100mm
Step-by-step explanation:
Multiply the length times the width
A quadratic function is a function of the form
. The
vertex,
of a quadratic function is determined by the formula:
and
; where
is the
x-coordinate of the vertex and
is the
y-coordinate of the vertex. The value of
determines if the <span>
parabola opens upward or downward; if</span>
is positive, the parabola<span> opens upward and the vertex is the
minimum value, but if </span>
is negative <span>the graph opens downward and the vertex is the
maximum value. Since the quadratic function only has one vertex, it </span><span>could not contain both a minimum vertex and a maximum vertex at the same time.</span>
Answer:
a + b = 5
Step-by-step explanation:
To solve this system of equations, we can use a strategy called elimination, which is when we get rid of a variable by adding/subtracting two equations.
Firstly, we want to make sure the absolute value of the coefficients that equal.
Lets eliminate b:
4a + 6b = 24
Multiply both sides by 2:
8a + 12b = 48
We also have:
6a - 12b = -6.
Now lets add that with
8a + 12b = 48
-> 6a + 8a + 12b - 12b = 48 -6
-> 14a = 42
-> a = 3
Now that we know a, lets plug it into one of our original equations:
4(3) + 6b = 24
12 + 6b = 24
6b = 12
b = 2
Finally, add the two values we found:
a+b = 2+3= 5
Yes they are equivalent fractions. If you multiply by 2 on both numbers for 2/3, you get 4/6.
