Answer:

D b = -2E +212

Step-by-step explanation:

The slope is given by -2 for every 1000 ft

The initial value is 212 degrees

We can use

y = mx+b where m is the slope and b is the initial value

y = -2x +212

We are at an elevation of E thousand ft

Replace x with E

y = -2 *E +212

b is the boiling point at this elevation

We replace y with b

b = -2E +212

Evan has graphed the point (5, 7) and he wants to reflect it over the line y=-2/5x+6. He predicts that the reflected point will

Whitepunk [10]

Given that Evan has graphed the point (5, 7) and he wants to reflect it over the line y=-2/5x+6. He predicts that the reflected point will have coordinates (2, 2).

Now we have to check if his answer is correct or not without graphing. Yes this is possible without graphing.

If his answer is correct then the line passing through points (5,7) and (2,2) will be perpendicular to the given line.

slope of line passing through the points (5,7) and (2,2) is given by :

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{7-2}{5-2}$

$m=\frac{5}{3}$

slope of the given line $y=-\frac{2}{5}x+6$ is $-\frac{2}{5}$

We know that If the two lines are perpendicular then product of their slopes equals -1

$-\frac{2}{5}*\frac{5}{3} = -\frac{2}{3}$

Which is not -1. That means both lines are not perpendicular.

Hence his answer is wrong.

Joe is the oldest of three brothers whose ages are consecutive even integers. Three times age of the Middle brother is 12 less t

ohaa [14]

Answer:

The age of Age of Joe is 14 years .

Step-by-step explanation:

Given as :

The statement is

Three times age of the Middle brother is 12 less than twice the sum of the ages of Joe and the youngest brother .

As The age of brothers are consecutive even integers

Let The Age of oldest brother Joe = 2 x + 4

Let The Age of middle brother = 2 x + 2

Let The Age of younger brother = 2 x

<u>Now, According to statement</u>

3 × (2 x + 2) = 2 × [ (2 x + 4) + (2 x) ] - 12

Or, 3 × 2 x + 3 × 2 = 2 × (2 x + 4) + 2 × (2 x) - 12

Or, 6 x + 6 = 2 × 2 x + 2 × 4 + 4 x - 12

Or, 6 x + 6 = 4 x + 8 + 4 x - 12

Or, 6 x + 6 = 8 x - 4

Or, 8 x - 6 x = 6 + 4

Or, 2 x = 10

∴ x = $\dfrac{10}{2}$

i.e x = 5

So, The age of Age of oldest brother Joe = 2 x + 4 = 2 × 5 + 4 = 14 years

The Age of middle brother = 2 x + 2 = 2 × 5 + 2 = 12 years

The Age of younger brother = 2 x = 2 × 5 = 10 years

Hence, The age of Age of Joe is 14 years . Answer

Michael and Derrick each completed a separate proof to show that corresponding angles AKG and ELK are congruent. Who completed t

Anarel [89]

Answer: Derrick

Step-by-step explanation:

$$$ Vertical Angle Theorem:- \\Vertical angle theorem or vertically opposite angles theorem states that two oppositevertical angles formed where two line intersect each other are always equal.$

$$$Solution: Michael used the incorrect vertical angle theorem in his statement. From figure \angle A K O T \cong L B K L(\because \text { Vertical angle theorem})$

$$$Therefore, Derrick gave the correct proof and so Michael's proof is incorrect$
