Answer:

The equations that are true are

B

C

E

Step-by-step explanation:

A) States that 0 + 451 = 0, but that is not true because...

    0 + 451 = 451

B) States that 130 + 210 = 210 + 130, and that is true because...

    130 + 210 = 210 + 130

    340 = 340

C) States that (127 + 80) + 250 = 127 + (80 + 250), and it is true because...

    (127 + 80) + 250 = 127 + (80 + 250)

    127 + 80 + 250 = 127 + 80 + 250

    457 = 457

D) States that (123 + 57) + 180 = 153 + (87 + 180), but that is not true because...

    (123 + 57) + 180 = 153 + (87 + 180)

    123 + 57 + 180 = 153 + 87 + 180

    360 = 420 (but this does not make sence)

E) States that 497 + 0 = 497, and it is true because...

    497 + 0 = 497

    497 = 497

What is the y-value of the vertex of the function f(x) = –(x – 3)(x + 11)?
Mrrafil [7]
Expand
f(x)=-1x^2-8x+33

x coordinate of vertex is -b/2a in the form ax^2+bx+c=y
a=-1
b=-8
-(-8)/2(-1)=8/-2=-4
plug back in to get y value

y=-(-4^2)-8(-4)+33
y=-16+32+33
y=49

y value is 49

Find the solution of 2/3x+1/4=-4/3
wolverine [178]
These questions can be daunting at first, but they're pretty simple to solve.

First, we need to establish a common denominator.  We have 2 / 3, 1 / 4, and
-4 / 3.  The least common denominator we can get is by multiplying 4 and 3 together to get 12.  So we will change the denominator as follows;

2 / 3, 1 / 4, -4 / 3  =  8 / 12, 3 / 12, -16 / 12

Now we can put these back into the equation.

8/12x + 3/12 = -16/12
8x + 3 = -16

It's simple math from here on out, but I'll show the process.  What we can basically do now is take away the denominator because it doesn't matter now that it's common.

Subtract 3 from both sides.  Now we have 8x = -19

Dividing by 8 on both sides of the equation will get you your answer.

x = -19/8


Hope this helps!
