Whats has the same slope of 6x-3y=9

Crank

Answer:

Step-by-step explanation:

when you put it into slope intercept form you get

The question is:

Naddik [55]

Answer:

2.5 gallons of the 20% solution must be replaced by the 36% solution.

Step-by-step explanation:

$.12(20 - x) + .36x = 20(.15)$

$2.4 - .12x + .36x = 3$

$2.4 - .24x = 3$

$- .24x = - .6$

$.24x = .6$

$x = 2.5$

A triangle has sides with lengths of 6 miles, 14 miles, and 15 miles. Is it a right triangle?

maks197457 [2]

Answer:

the triangle is not right angled traingle

Step-by-step explanation:

For a right angle triangle

$a^{2}$ + $b^{2}$ = $c^{2}$ where a is the base , b is the height and c is the hypotenuse

taking a= 6 b = 14 and c = 15

hence $6^{2}$ + $14^{2}$ = $15^{2}$

36+196 = 232 which is not equal to 225

therefore the triangle is not right angled traingle

5x+5y are like terms and can be added together to simplify to 10xy A.True B.False

Alja [10]

Step-by-step explanation:

B. False

they cannot be written as 10xy but only in 5x+5y

x and y will only become together if they are multiplied

as you can see there's a plus sign

you can add them if it is in 5x+5x (or) 5y+5y but never as in 5x+5y
