I'm guessing you're trying to simplify the equation since there is no other information lol

[(2x+y)-3]

So basically when you are trying to simplify equations you have to add the same variables together (In this case X & Y) But since there are no alike variables there really is nothing to add

So your answer would be 2x+y-3

Hoped this helped

What is the slope of the line through (3, 2) and (-3, 4)?

tresset_1 [31]

Answer:

C

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (- 3, 4)

m = $\frac{4-2}{-3-3}$ = $\frac{2}{-6}$ = - $\frac{1}{3}$ → C

A small craft in lake Ontario sends out a distances signal. The coordinates of the boat in trouble are (57,64). One rescue boat

KatRina [158]

Answer:

The coast guard craft will get to the distressed boat the fastest.

Step-by-step explanation:

The coordinates of boat are (57,64).

The coordinates of rescue boat are (67,83).

The coordinates of coast guard craft are (65,46).

Both rescue crafts travel at the same rate. One of them will get to the distressed boat the faster, whose distance from the boat is least.

Distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The distance between boat and rescue boat is

$d_1=\sqrt{(67-57)^2+(83-64)^2}=21.4709105536\approx 21.47$

The distance between boat and coast guard craft is

$d_2=\sqrt{(65-57)^2+(46-64)^2}=19.6977156036\approx 19.70$

Since the distance between boat and coast guard craft is least, therefore coast guard craft will get to the distressed boat the fastest.

If AX) = x2 + 2x + 3, what is the average rate of change of AX) over the interval (-4, 6]? OA 51 B. 40 OC. 31 OD 20 OE 4

Yuki888 [10]

Answer:

E

Step-by-step explanation:

The average rate of change of A(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ - 4, 6 ] , then

f(b) = f(6) = 6² + 2(6) + 3 = 36 + 12 + 3 = 51

f(a) = f(- 4) = (- 4)² + 2(- 4) + 3 = 16 - 8 + 3 = 11 , thus

average rate of change = $\frac{51-11}{6-(-4)}$ = $\frac{40}{10}$ = 4 → E
