Step-by-step explanation:

For a line to be parallel it must have the same slope

6x-2y=-5

+5 +5

6x-2y+5 = 0

+2y +2y

6x+5 =2y

/2 /2

3x+5/2=y So the slope is 3 and we know it can only be either B or D

Now we need to find which line passes through (7,-2) and we find this by plugging 7 into B and D

B. -2= 21-23 TRUE

D. -2 = 21+ 23 FALSE

So the answer is B

The sum of two numbers is 72 while the difference between the numbers is 25. the larger of the numbers is

7nadin3 [17]

2 equations: the first one is the sum of 2 unknown numbers x and y: x + y = 72. Now the difference is 25, so x - y = 25. Solve the first equation for y: y = 72 - x. Sub that into the second equation to solve for x: x - (72 - x) = 25. x - 72 + x = 25 and 2x - 72 = 25. Therefore, 2x = 97 and x = 48.5 That's the larger of the 2 numbers; since we subtracted y from x we defined x as the larger of the 2. Just for fun, plug x in to find that y = 23.5

0=4t-16t^2 Solve this please

vaieri [72.5K]

Answer:

$\large\boxed{t=0\ \vee\ t=\dfrac{1}{4}}$

Step-by-step explanation:

$4t-16t^2=0\qquad\text{divide both sides by 4}\\\\\dfrac{4t}{4}-\dfrac{16t^2}{4}=\dfrac{0}{4}\\\\t-4t^2=0\\\\t(1-4t)=0\iff t=0\ \vee\ 1-4t=0\\\\1-4t=0\qquad\text{subtract 1 from both sides}\\\\-4t=-1\qquad\text{divide both sides by (-4)}\\\\t=\dfrac{1}{4}$
