If (x, 9) is a solution to 5x - 2y = 12, what is the value of x ?
lina2011 [118]
X= 6


Explanation:

y=9 so rewrite the equation like this:


5x-2(9)=12

Multiply -2 by 9:


5x-18=12

Cancel out the -18:


5x-18=12
+18 +18


5x=30


Divide both numbers by 5:


5x/5 = 30/5


As an answer, you will get x=6:

Hope this helped:)

Whats the slope for 3x + 2y = -10
Cerrena [4.2K]

Answer:

Subtract 3 x 3 x from both sides of the inequality. Divide each term by - 2 − 2 and simplify. Tap for more steps... Divide each term in - 2 y < 10 - 3 x − 2 y < 10 − 3 x by - 2 − 2. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign

PLEASE HELP!!! PLEASE EXPLAIN AND SHOW WORK!!!! THANK YOU !!!!
liraira [26]

Answer:

t = 2.5 s

Step-by-step explanation:

h(t)=-16t^2 +80t+96

height will be greatest when the derivative (velocity) is zero

h'(t) = v(t) = -32t + 80

            0 = -32t + 80

         32t = 80

             t = 80/32 = 2.5 s

notice that 0 = -32t + 80 is just a version of the kinematic equation

v = u + at

where v is final velocity at the top of the arc or zero

u is the initial upward velocity or 80 ft/s

a is gravity or -32  ft/s²

t is time in seconds
