Answer:

a² - b²

Step-by-step explanation:

We can recognize (a + b)(a - b) as a difference of squares.

Step 1: Write expression

(a + b)(a - b)

Step 2: FOIL (Expand)

a² - ab + ab - b²

Step 3: Combine like terms

a² - b²

Answer:

3 days.

Step-by-step explanation:

Based on the information provided we see that roughly 60% of the days in January have 6ft+ waves then we would need to use this value to calculate the number of days that are good for surfing. We calculate this by multiplying the number of days that you can surf by 60% using the equation below as r being the actual total amount of days....

r = 6 * 0.60%

r = 3.6

As we can see that there are roughly 3 days that see this amount of wave activity between the 6 chosen dates. We have to round down because we are talking about full days and 3.6 does not meet a fourth full day.

Answer: [tex]m[/tex] = −3

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Expand.

−40 − 6[tex]m[/tex] − 1 = 7[tex]m[/tex] − 2

Step 2: Simplify −40 − 6[tex]m[/tex] − 1 to −6[tex]m[/tex] − 41.

−6[tex]m[/tex] − 41 = 7[tex]m[/tex] − 2

Step 3: Add 6[tex]m[/tex] to both sides.

−41 = 7[tex]m[/tex] − 2 + 6[tex]m[/tex]

Step 4: Simplify 7[tex]m[/tex] − 2 + 6[tex]m[/tex] to 13[tex]m[/tex] − 2.

−41 = 13[tex]m[/tex] − 2

Step 5: Add 2 to both sides

−41 + 2 = 13[tex]m[/tex]

Step 6: Simplify −41 + 2 to −39.

−39 = 13[tex]m[/tex]

Step 7: Divide both sides by 13.

−[tex]\frac{39}{13}[/tex] = [tex]m[/tex]

Step 8: Simplify [tex]\frac{39}{13}[/tex] to 3.

−3 = m

Step 9: Switch sides.

[tex]m[/tex] = −3

Answer:

  y = 2/3x -23/3

Step-by-step explanation:

In a version of point-slope form this is ...

  y = m(x -h) +k . . . . . line with slope m through point (h, k)

Expanding this, we have ...

  y = mx +(k -mh) . . . . slope-intercept form

For the given point and slope, the equation is ...

  y = 2/3x +9 -2/3(2)

  y = 2/3x -23/3

Answer: Unit rate = 1 1/2 cups per serving

Step-by-step explanation:

1/2 serving has = 3/4 cup

1 serving will have = 3/4 1/2 = 3/4 x 2/1 = 6/4 = 6 ÷ 2/ 4 ÷ 2 = 3/2 = 1 1/2cups

Since Mai has proven triangles WYZ and WYX to be congruent by the SSS triangle Congruence Theorem, she can conclude that:

Diagonal WY bisects angles ZWX and ZYX because:

If two triangles are proven to be congruent to each other, it means that all three pairs of corresponding sides and angles of both triangles are congruent and equal to each other.

Thus, since Mai has proven triangles WYZ and WYX to be congruent by the SSS Triangle Congruence Theorem, therefore, all corresponding parts of both triangles are congruent.

If this is so, then Mai can conclude that angles ZWX and ZYX are bisected by diagonal WY. (Option A is correct).

The graph of the quadratic function x²+4x=-2x+16 is a parabola that crosses the x-axis at x=-8 and x=2. Correct option is (a).

Let ax² +bx +c = 0 is an quadratic equation its zeroes are the values of x for which the Left hand side becomes zero.

To find zeroes we can use quadratic formula that is

x = (-b ±√(b²-4ac))/2

Graph of the quadratic equation are points ( x , y(x) )

where y(x) =  ax² +bx +c

when x= t is zero of quadratic equation ax² +bx +c = 0

then y(t) = 0

(t, 0) points are points on the x-axis.

Given an quadratic equation

x²+4x=-2x+16 has roots x =-8 and x =2

This can we written as  x² +6x -16 =0

The graph of  this quadratic equation is given by (x, y(x))

where y = x² +6x -16 which is a parabola

for x= -8 and x= 2 , y(-8) =y(2) = 0

Then (-8,0)  and (2,0) are points on this parabola which are at x-axis

Therefore, the parabola y = x² +6x -16  crosses the x-axis at x=-8 and x=2.Thus (a) is the correct option.
