1) x^2=36
x=6
3) x^2-8x+13=0 —> x= (8±√64-4(1)(13))/2(1)
x=4±√3
5) x^2-6x+9-k=0 —> x=(6±√36-4(1)(9-k))/2(1) —> (6±√4k)/2 —> (6±2√k)/2
x=3±√k
7) y=x^2-4x+11 —> y-11=x^2-4x —> take the half of the coefficient of the single x term and square it and add it on both sides —> y-11+4=x^2-4x+4 —> y-7=(x-2)^2 —> y=(x-2)^2+7
Minimum: (2,7)
Maximum: n/a
X intercepts: none (never crosses the x-intercept)
9) y=x^2+2x-8 —> y+8+1=x^2+2x+1 —> y=(x+1)^2-9
Minimum: (-1,-9)
Maximum: n/a
x-intercepts: (x+4)(x-2) —> (-4,0),(2,0)
11) c
13) (x+7)(x+3)
15) x=(-6±√36-4(1)(10))/2 —> x=(-6±√-4)/2 —> (-6±2i)/2
x=-3±i OR no real solutions
The possible values of x are x > 0.5
The given diagram is a quadrilateral. From the diagram we can see that;
3x + 2 > x + 3 (according to the length)
Solve the resulting inequality
3x - x > 3 - 2
2x > 1
x > 1/2
x> 0.5
Hence the possible values of x are x > 0.5

Answer:
None
Step-by-step explanation:
Because mode is a set of data values is the value that appears most often. If there is no data value or data values that occur most frequently, we say that the set of data values has no mode.
Answer:
There will be 11 mozzarellas and 6 pizza rolls
Step-by-step explanation:
80x+90x=1740,5x+x=6x,
80(6)+90x=1740,1740-480=990,
90x=990,x=11
