Answer:
Step-by-step explanation:
A
(2x - 5)(x + 1)
B)
The x intrcepts occur when the factors equal zero.
2x - 5 = 0
2x = 5
x = 5/2
x = 2 1/2
C
I will give the the minimum from completing the square
y = 2(x - 0.75)^2 - 6.125
as x approaches + infinity, y approaches + infinity.
as x approaches - infinity, y approaches + infinity.
It's a quadratic. The y values go to plus infinity, when x goes from - infinity to + infinity.
D
Desmos is the most useful tool for this part of the question. What it shows is the two roots and the minimum at (0.75,-6.125. A parabola does what the end behavior describes. The roots are clearly labeled as is the minimum.
Well, it says that 34 kids like physics and since there is 100 students, we know 34% of the kids like physics. This means 66% like biology.
So a number (x because unknown) divided by 40 (x divided into 40 parts or x/40) has a quotient of 6 with a remainder of 16 (answer=6 with 16 remainder)
remember that remainder is not involved in division, just leftover
x/40=6+16 remainder
to get rid of the fraction, multiply the whole equation by 40 and add the remainder (since it wasn't involved in division)
x=240+16
x=256

number=256

Step-by-step explanation:
Answer:
The inside angle b is 50
Step-by-step explanation:
Since the angles of a triangel must = 180 degrees we subtrace 75 from 180 to get 180-75=105 and from there we know that angle a must be equal to angle c so 75+50-125 and then 180-125 = 55 so the inside angle of A must be 55 we get 105 back and subtract 55 from that to get 50 so b is equal to 50
