The function <span>6x^3 - 5y^2 is a C. binomial because there are 2 terms, and the prefix "bi" means 2.</span>
Answer:
3(4x + 1)(x - 4) Answer choice B
Step-by-step explanation:
-12x^2 + 45 + 12
You would take out the -3 in the equation.
-3(4x^2 -15x - 4)
You can then multiply the first 4 and the last -4 and get a -16. You can then find two numbers that would multiply to -16 and add to -15.
You would do this by listing the factors of -16, which the numbers 1 and -16 would work.
You would then substitute each value in for the 17x and add them together, which this is just separating the value 17x.
3(4x^2 - 16x + x - 4)
3(4x^2 - 16x)(x - 4)
You can then take ou ta four for the first function in the parentheses.
3(4x(x - 4) 1(x - 4))
Then you take the function from the outside and the inside.
3(4x + 1)(x - 4)
The answer to the question would be B.
Answer:
I cannot see the question clearly. But I know how to do .
5*4/4 +1/4
20/4+1/4
21/4
You can multiply the whole number by 1, for the same number...but in the terms you need...for example, 5/5=1, but by multiplying by that, you'll get the number /5
1) This equation is a polynomial to the second power, so lets use the quadratic formula.
<span>[ -B +- squareroot(B^2 - 4AC) ] / 2A -A bit hard to read without the actual format. </span>
<span>= [ -20 +- squareroot( 20^2 - (4)(-5)(60) ) ] / (2)(-5) -A corresponds to -5, B to 20, and C to 60. Plug in. </span>
<span>= [ -20 +- squareroot(400 - (-1200) ) ] / (-10) - Simplifying.... </span>
<span>= [-20 +- 40] / (-10) </span>
<span>Because there is a plus/minus we now have two equations. </span>
<span>= [-20 - 40] / (-10) and = [-20 + 40] / (-10) </span>
<span>= 6 = -2 </span>
<span>Now in case you aren't extremely familiar with the quadratic equation, by plugging in each piece and solving, we get the two x-intercepts that this parabola equation crosses and a graph. Lucky for us, this means that the two numbers we solved for is equal to the time at which this object touches the ground. </span>
<span>Common sense solves the rest. You cant have negative time so -2 is off our list. </span>
<span>****That means it will take 6 seconds for this object to hit the ground. ***** </span>
<span>2) We have f(x)=2x+12 and x is the amount of movies, and this function gives us the cost of the rental. </span>
<span>She requires 7 movies, so all we have to do is simply plug in 7 for x. </span>
<span>f(x) = 2x + 12 </span>
<span>= 2(7) + 12 </span>
<span>= 14 + 12 </span>
<span>= $26 -So the cost for 7 movies will be $26. </span>
<span>We know she already has $10 so we just subtract $26 - $10 and we get $16. </span>
<span>**** In order for her to rent 7 movies, makayla needs $16 more dollars.****</span>
