How<span> you would factor this is,

</span>The two terms of the binomial equation 25x<span>^2 + -9 = 0 are perfect square. When factoring the difference of two perfect squares: x^2 – a^2 = (x+a)(x-a) . STEP 2: Set up and solve the equation. (5x) (5x) + (5x) (-3) + (3) (5x) + (3) (-3) = 0 With the Distributive Prop

If I understood the question correctly you can think of 25x^2-9 as being 25x^2+0x-9.  Therefore a=25, b=0, and c=-9.  Using the quadratic formula x=(-b(+or-)√(b²-(4ac)))/(2a).  after solving this equation with the given a, b, and c values you should get x=3/5 and -3/5.

East Middle's football team was positioned on the 50 yard line. After a penalty is called, the football team is pushed back 5 ya
Rufina [12.5K]

Answer:

The answer would be the 35 yard line.

Step-by-step explanation: This is because if they get a 5 yard penalty 3 times, that would be a total of 15 yards lost. So, you would do 50-15, getting 35, so boom, 35 yard line :)

A pair of equations is shown below:
Archy [21]

Slope Intercept Form - y = mx + b

First you need the slope or m which in the first equation is 6 and in the second is 5

Next the y-intercept or b which in the first equation is -4 and in the second is -3

Here is an image of both equation plotted on a graph where the first equation is purple and the second is green

Hope this helps, if you need anything else i will edit it in :)

edit: The to lines intercept at the point (1,2)

Sorry, i wasn't completely sure what you needed i haven't done this in a while. If you still need more, I'll try to help.

In what year 200, the population of Virginia was about 7,400,000.
Rus_ich [418]
For this case we have the following function:
 f (x) = 7,400,000 (1,054) ^ x
 Where,
 x represents time in years.
 Substituting f (x) = 15000000 we have:
 15000000 = 7,400,000 (1,054) ^ x
 Clearing x we have:
 (1,054) ^ x = (15000000) / (7400000)
 log1.054 ((1.054) ^ x) = log1.054 ((15000000) / (7400000))
 x = log1.054 ((15000000) / (7400000))
 x = 13.4 years
 Rounding to the nearest year:
 x = 14 years
 Answer:
 
the population will reach 15,000,000 in 2014.
