(-3,-2)(3,2)
so slope = (2 + 2)/(3+3) = 4/6 = 2/3
y = mx + b
b = y - mx
b = -2 - (2/3)(-3)
b = -2 + 2
b = 0

equation
y = 2/3x

answer
B. <span>y = 2/3x</span>

Answer: Choice B

The slope is rise/run = 2/3 meaning we go up 2 and over to the right 3. For instance, moving from (0,0) to (3,2) has us move up 2 and over to the right 3.

Alternatively you can use the slope formula m = (y2-y1)/(x2-x1) to get the same result of 2/3.

lana [24]

Answer:

Bryce's speed (slow speed I might add) is 3 miles per hour.

Explanation:

s /d= t

where

s = speed d= distance t = time.

Solving for gives:

s = 1/3 / 1/9

s= 9/3

s= 3 miles per hour

The question is incomplete. Here is the complete question:

Mr.yueng graded his students math quizzes students came up with four different answers when solving the equation x3=22. Which answers is correct.

(A) $\frac{22}{3}$

(B) $\sqrt[3]{22}$

(C) $\pm \sqrt[3]{22}$

(D) $\sqrt{22}$

Answer:

(B) $\sqrt[3]{22}$

Step-by-step explanation:

Given:

The equation to solve is given as:

$x^3=22$

Here, the left hand side of the equation has a variable 'x' in exponent form. So, in order to solve for 'x', we have to eliminate the exponent.

For removing the exponent, we have to take cubic root on both the sides. As we know that,

$\sqrt[n]{x^n} =x$

So, taking cubic root on both the sides, we get

$\sqrt[3]{x^3}=\sqrt[3]{22}\\\\x=\sqrt[3]{22}$

Therefore, the second student has written the correct answer and hence the correct option is (B).

Someone solve this equation much appreciated!

daser333 [38]

Answer:

$\frac{2A}{h} = b$

Step-by-step explanation:

this can be done by simple manipulation .
in the given equation, A is the subject.
so, by the above statement you can understand the meaning of making something as a subject.

given equation: A = 1/2 bh

multiply both the sides by 2,

2A = bh

divide both the sides by h,

$\frac{2A}{h} = b$

so, the required form is : $\frac{2A}{h} = b$
