Answer:
10 2/10
Step-by-step explanation:
because together it equals 9 12/10 but that cant happen so you add 1 to the 9 and get 10 so you have 2 left over
Mark me as brainliest
First step, list your A,B,C’s.
A=5
B=-9
C=-116
The quadratic formula is:
y= -b +/- the square root of b^2-4(a)(c)
———————————————————-
2a
^ all of that is divided by 2(a)
now you wanna fill in your a,b,c’s.
(im gonna use sr to shorten (s)quare (r)oot)
y= -(5)
Answer:
- v = 8
- x = -12
Step-by-step explanation:
1. I like to work with positive numbers, so the first thing I'd do is multiply the equation by -1.
2v + 7 = 23
2v = 16 . . . . . subtract 7
v = 8 . . . . . . . divide by 2
<em>Check</em>
-2(8) -7 = -23 . . . . true
___
2. (x/4) -5 = -8
x/4 = -3 . . . . . . . add 5
x = -12 . . . . . . . . multiply by 4
<em>Check</em>
(-12/4) -5 = -8 . . . . true
The answer is 7794, rounded is 7790.
Since the 4 in the ones place is not greater than 5, you round down and get 0.
