Answer:
24
Step-by-step explanation:
First we must recognize that this equation is a quadratic function, therefore we can use the quadratic equation and look only at the discriminate portion of that formula. However, before doing so we need to set up our equation by taking the 1 to the other side and so:
And we know that in general a quadratic function is such that:
And so our quadratic equation is:
But we only need to look at what's under the square root meaning:
This is our discriminant and since a=5, b=2 and c=-1 we have:
Answer:
(-9.5, 6.75)
Step-by-step explanation:
I inputted both equations on the desmos website and they met at this point
Answer:
51.28%
Step-by-step explanation:
since the test is worth 60% of your grade, the rest is worth 40%
calculate your new grade by multiplying each grade percent (as written) by the percent of your grade (as a decimal):
77.2(0.4) = 30.88
34(0.6) = 20.4
then add them together: 30.88 + 20.4
Answer:
B) 181
Step-by-step explanation:
3*5=15
45*4=180
24/2=12
12-4=8
5*2=10
15+190-12+10-10=181
Move the 14 over and get
5x = 2
divide by 5
x = 2/5
