Find slope and y-intercept<br> 5x+3y=-6

katen-ka-za [31]

Answer:

$m=-\frac53; q=-2$

Step-by-step explanation:

Let's bring the line in the classical $y=mx+q$ form

$3y= -5x-6\\y=-\frac53 x -2$

At this point we have the two values $-\frac53$ for the slope and $2$ for the intercept

What is the x please answer me quick

nordsb [41]

First u do a squared +b squared =c squared aka pythagorean theorem then so u already have c squared so you would do 5x5=25 and 13x13=169 so then the equation would be 25+?=169 then do 169-25 which equals 144 and then do the square root of that which is 12 THE ANSWER IS 12

13. What is the result of adding 5.4a + 7.1 and -1.28 - 6.3?

den301095 [7]

Answer:

C. 4.2a + 0.8

Step-by-step explanation:

Given:

The two binomials given for addition are:

$5.4a+7.1$ and $-1.2a-6.3$

Now, adding both the binomials, we get:

$5.4a+7.1+(-1.2a-6.3)$

Distributing the positive sign inside the second binomial, we get:

$5.4a+7.1-1.2a-6.3$

Now, combining like terms using the commutative property of addition, we get:

$(5.4a-1.2a)+(7.1-6.3)$

Simplifying the above expression, we get:

$(5.4-1.2)a+0.8\\4.2a+0.8$

Therefore, the resulting addition of the given binomials is $4.2a+0.8$

Hence, option C is the correct answer.

How many natural numbers N have the property among 1,2,..........,N exactly 30% are divisible by 3?

k0ka [10]

Answer:

The answer is B. 2.

Step-by-step explanation:

We know that for N = 1 and N = 2, none of them are divisible by 3.

For N = 3, 33.33% are divisible by 3. For N = 4, 25% (which is already less than 30%), so N = 5 would also be less.

At N = 6, we're back up to 33.33%. N = 7 is already less than 30%.

At N = 9, you guessed it, 33.33%. N = 10 is 30% (3, 6, and 9). So we have one case.

Moving along, at N = 18, 33.33%. N = 20 is again 30% (3, 6, 9, 12, 15, and 18). Two cases now.

Finally, at N = 21, again 33.33%. N = 22 and N = 23 are both greater than 30%. As we continue this, for any N after 20, we will always be greater than 30%.
