First, simplify. Combine each term. Remember to follow the Left to right rule

6/2 = 3 x 3 = 9

3 x 3 = 9

Finally, divide

9/9 = 1

(C) 1 is your answer

hope this helps

6/2*3 / 3(3)

First simplify the numerator: 6/2*3 = 3*3 = 9

Next simplify the denominator: 3(3) = 3*3 = 9

So you have 9/9, which equals 1.

The 3rd answer is correct.

Graph f(x) = x2 + 2x - 3, label the function’s x-intercepts, y-intercept and vertex with their coordinates. Also draw in and lab

Semenov [28]

<h2>Answer with explanation:</h2>

The given function : $f(x)=x^2+2x-3$

Using completing the squares, we have

$f(x)=x^2+2x+1-1-3$ [∵ $(x+1)^2=x^2+2x+1$ ]

$f(x)=(x+1)^2-4$ (1)

Comparing (1) to the standard vertex form $f(x)=(x-h)^2+k$ , the vertex of function is at (h,k)=(-1,-4)

For x-intercept, put f(x)=0 in (1), we get

$0=(x+1)^2-4\\\\\Rightarrow\ (x+1)^2=4$

Square root on both sides, we get

$x+1=\pm2\\\\x+1=-2\ or\ \ x+1=2\\\\=x=-3\ \ or\ x=1$

∴ x intercepts : x= (-3,0) and (1,0)

For y-intercept put x=0 in (1), we get

$f(1)=(1)^2-4=1-4=-3$

∴ y intercept : (0,-3)

Axis of symmetry : $\dfrac{-b}{2a}$

In $f(x)=x^2+2x-3$ , a=1 and b=2

Axis of symmetry= $\dfrac{-2}{2(1)}=-1$

Which operations are the most efficient to use to solve the problem and what is the solution? Lucas is making a banner that has

ivolga24 [154]

So, first what we should do is divide 2,046 by 62 to find the width of Lucas's banner.

2,046 / 62 = 33 The width of Lucas's banner is 33 cm.

Which means if the width of Emily's banner is 3x that:

3 x 33 = 99 Emily's banner is 99 cm in width.

So, your 2 answers are: 99 cm, division and multiplication. ;)
