we have

$2x+3y=-12$

Isolate variable y

$2x+3y=-12$

Subtract $2x$ both sides

$3y=-2x-12$

Divide by $3$ both sides

$y=-\frac{2}{3}x-4$

the slope m is equal to

$m=-\frac{2}{3}$

therefore

<u>the answer is the option B</u>

$-\frac{2}{3}$

Find the value of x. Express your answer in simplest radical form

klemol [59]

Since x=x, this is an isosceles right triangle. By the Pythagorean Theorem:

h^2=a^2+b^2 (the hypotenuse squared is equal to the sum of the squared sides)

5^2=x^2+x^2

25=2x^2

2x^2=25

x^2=25/2

x=√(25/2)

x=5/√2 now if we rationalize the denominator...

x=(5√2)/(√2√2)

x=(5√2)/2

3. If ‘A’ can finish a work in ‘n’ days then part of work finished in 1 day is: (a) 1 – n

zaharov [31]

Answer:

If ‘A’ can finish a work in ‘n’ days then part of work finished in 1 day

will be $\frac{1}{n}$ .

Step-by-step explanation:

From the question, it is clear that

If ‘A’ can finish a work in ‘n’ days, then
we have to determine the part of work finished in 1 day.

let ' $n$ ' be the number of days $A$ takes to complete the whole work

Let the whole job be denoted as ' $1$ '

Thus, the part of work finished in 1 day will be:

$\:\frac{Total\:work}{Time\:taken\:by\:A\:to\:complete\:the\:work}\:=\frac{1}{n}$

Therefore, If ‘A’ can finish a work in ‘n’ days then part of work finished in 1 day will be $\frac{1}{n}$ .

HELP ME PLEASE! Vector's map has the scaling missing.he knows from the lake to the youth center is 8 miles. on the map, they are

Naddik [55]

Hey there!

Since 2 goes into 8, you would simplify. You would get 1 inch and 4 miles. Next, set up a ratio. The ratio is 1 inch: 4 miles. So for every inch on the map, there is 4 miles.

I hope this helps!
